The entire system (combination of indoor and outdoor sections) must be manufacturer approved and Air Conditioning, Heating, and Refrigeration Institute (AHRI) listed.
NOTE: Installation of unmatched systems is not permitted.
5.3 Interconnecting Tubing
Give special consideration to minimize the length of refrigerant tubing when installing air handlers. Refer to Remote Cooling / Heat Pump Service Manual RS6200006,and TP-107 Long Line Set Application R-410A for tubing guidelines. If possible, allow adequate length of tubing such that the coil may be removed (for inspection or  cleaning services) from the cabinet without disconnecting the tubing.
5.4 Clearances
The unit clearance from a combustible surface may be 0”. However, service clearance must take precedence. A minimum of 24” in front of the unit for service clearance is required. Additional clearance on one side or top will be required for electrical wiring connections. Consult all appropriate regulatory codes prior to determining final clearances. When installing this unit in an area that may become wet (such as crawl spaces), elevate the unit with a sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install a protective barrier to prevent such damage. Always install units such that a positive slope in condensate line (1/4” per foot) is allowed.
5.5 Horizontal Applications
If installed above a finished living space, a secondary drain pan (as required by many building codes), must be installed under the entire unit and its condensate drain line
must be routed to a location such that the user will see the condensate discharge.

Installation Location

 Refrigerant Lines

WARNING
THIS PRODUCT IS FACTORY-SHIPPED WITH R410A AND DRY NITROGEN MIXTURE GAS UNDER PRESSURE. USE APPROPRIATE SERVICE
TOOLS AND FOLLOW THESE INSTRUCTIONS TO PREVENT INJURY.
NOTE: Refrigerant tubing must be routed to allow adequate access for servicing and maintenance of the unit. Do not install the air handler in a location that violates the instructions provided with the condenser. If the unit is located in an unconditioned area with high ambient temperature and/or high humidity, the air handler may be subject to nuisance sweating of the air handler cabinet. On these installations, a wrap of 2” fiberglass insulation with a vapor barrier is recommended.
7.1 Tubing Size
For the correct tubing size, follow the specification for the condenser/heat pump.
7.2 Tubing Preparation
All cut ends are to be round, burr free, and clean. Failure to follow this practice increases the chances for refrigerant leaks. The suction line is spun closed and requires tubing cutters to remove the closed end.
NOTE: To prevent possible damage to the tubing joints, do not handle coil assembly with manifold or flowrator tubes. Always use clean gloves when handling coil assemblies.
NOTE: The use of a heat shield is strongly recommended when brazing to avoid burning the serial plate or the finish of the unit. Heat trap or wet rags must be used to protect heat sensitive components such as service valves and TXV valves sensing bulb.
WARNING
A QUENCHING CLOTH IS STRONGLY RECOMMENDED TO PREVENT SCORCHING OR MARRING OF THE EQUIPMENT FINISH WHEN BRAZING CLOSE TO THE PAINTED SURFACES. USE BRAZING ALLOY OF 5% MINIMUM SILVER CONTENT.
CAUTION
APPLYING TOO MUCH HEAT TO ANY TUBE CAN MELT THE TUBE. TORCH HEAT REQUIRED TO BRAZE TUBES OF VARIOUS SIZES MUST BE PROPORTIONAL TO THE SIZE OF THE TUBE. SERVICE PERSONNEL MUST USE THE APPROPRIATE HEAT LEVEL FOR THE SIZE OF THE  TUBEBEING BRAZED.
7.3 Tubing Connections
An adjustable TXV with bulb is installed on the vapor tube from the factory.

1. Remove refrigerant tubing panel or coil (lower) access panel.
2. Remove access valve fitting cap and depress the valve stem in access fitting to release pressure. No pressure indicates possible leak.
3. Replace the panel.
4. Remove the spin closure on both the liquid and suction tubes using a tubing cutter.
5. Insert liquid line set into liquid tube expansion and slide grommet about 18” away from braze joint.
6. Insert suction line set into suction tube expansion and slide insulation and grommet about 18” away from braze joint.
7. Braze joints. Quench all brazed joints with water or a wet rag upon completion of brazing.

IMPORTANT NOTE: Ensure coil slides on the rails along the groove provided on the drain pan side walls. Failure to do so will result in improper condensate drainage.
7.4 Thermal Expansion Valve System Adjustment The following information for the indoor unit should be verified before attempting to charge system or adjust TXV if
necessary.

1. Total static pressure is .5” WC or less.
2. Airflow is correct for installed unit.
3. Airflow tables are in the installation manual and Spec Sheet for Indoor Unit.
4. Complete airflow tables and charging information are in Service Manual RS6200006.
5. The outdoor temperature must be 60°F or higher.
6. Set the room thermostat to COOL, fan switch to AUTO.
7. Set the temperature control well below room temperature.

Superheat adjustments should not be made until indoor ambient conditions have stabilized. This could take up to 24 hours depending on indoor temperature and humidity. Before checking superheat run the unit in cooling for 10 minutes or until refrigerant pressures stabilize. Use the following guidelines and methods to check unit operation and ensure that the refrigerant charge is within limits.
NOTE: Charge two stage units on low stage.

1. Purge gauge lines. Connect service gauge manifold to base-valve service ports.
2. Temporarily install a thermometer on the liquid line at the liquid line service valve and 4-6” from the compressor on the suction line. Ensure the thermometer makes adequate contact and is insulated for best possible readings. Use liquid line temperature to determine subcooling and vapor temperature to determine superheat.
3. Check subcooling and superheat. The system should have a subcooling of 8°F +/- 1°F and two-stage compressor systems should have a Subcooling of 6°F +/- 1°F. and superheat of 8°F +/- 1°F. If subcooling and superheat are low, adjust TXV to 8°F +/- 1°F superheat, then check subcooling.
   a. If subcooling is low and superheat is high, add charge to raise subcooling to 8°F +/- 1°F. Two-stage compressor systems should have a Subcooling of 6°F +/- 1°F then check superheat.
   b. If subcooling and superheat are high, adjust TXV valve to 8°F +/- 1°F superheat, then check subcooling.

Superheat Adjustments (Only if necessary)

1. Attach a pipe clamp thermometer near the suction line service valve at the outdoor unit.
   a. Ensure the thermometer makes adequate contact for the best possible readings.
2. TXV-based systems should have a Superheat value of 8°F +/- 1°F.
3. Adjust Superheat by turning the TXV valve stem clockwise to increase and counterclockwise to decrease. Adjustments should be made opening or closing the valve by no more than ¼ turn at a time. Allow the system to stabilize 15 to 20 minutes before making additional adjustments if necessary.
4. After adjustments are complete replace cap on adjustment stem and tighten 1/6 turn.
   5. Remove gauges and check the Schrader ports for leaks and tighten valve cores if necessary. Install caps finger tight.

NOTE: In situations where the TXV must be removed and replaced or re-installed into the system, the TXV should be hand tightened first and then apply a half turn to fully set the TXV. No more than 20 ft-lb torque should be applied to the joints of the TXV.

SUBCOOL FORMULA = SAT. LIQUID LINE TEMP. – LIQUID LINE TEMP.
SUPERHEAT FORMULA = SUCT. LINE TEMP. – SAT. SUCT. TEMP.

Condensate Drain Lines

The coil drain pan has a primary and a secondary drain with 3/4” NPT female connections. The connectors required are 3/4” NPT male, either PVC or metal pipe, and  should be hand tightened to a torque of no more than 37 in-lbs. to prevent damage to the drain pan connection. An insertion depth of approximately 3/8” to 1/2” (3-5 turns) should be expected at this torque.

1. Ensure drain pan hole is not obstructed.
2. To prevent potential sweating and dripping on to finished space, it may be necessary to insulate the condensate drain line located inside the building. Use Arm flex® or similar material.

A secondary condensate drain connection has been provided for areas where the building codes require it. Pitch all drain lines a minimum of 1/4” per foot to provide free drainage. Provide required support to the drain line to prevent bowing.
If the secondary drain line is required, run the line separately from the primary drain and end it where condensate discharge can be easily seen.
NOTE: Water coming from secondary line means the coil primary drain is plugged and needs immediate attention.
CAUTION
IF SECONDARY DRAIN IS NOT INSTALLED, THE SECONDARY ACCESS MUST BE PLUGGED.
Insulate drain lines located inside the building or above a finished living space to prevent sweating. Install a condensate trap to ensure proper drainage.
NOTE: When units are installed above ceilings, or in other locations where damage from condensate overflow may occur, it is MANDATORY to install a field fabricated auxiliary drain pan under the coil cabinet enclosure.
The installation must include a “P” style trap that is located as close as is practical to the evaporator coil. See Figure 12 for details of a typical condensate line “P” trap.
NOTE: Units operating in high static pressure applications may require a deeper field constructed “P” style trap than is shown in Figure 12 to allow proper drainage and prevent condensate overflow.

NOTE: Trapped lines are required by many local codes. In the absence of any prevailing local codes, please refer to the requirements listed in the Uniform Mechanical Building Code.
A drain trap in a draw-through application prevents air from being drawn back through the drain line during fan operation thus preventing condensate from draining, and if connected to a sewer line to prevent sewer gases from being drawn into the airstream during blower operation.
Use of a condensate removal pump is permitted when necessary. This condensate pump should have provisions for shutting off the control voltage should a blocked drain
occur. A trap must be installed between the unit and the condensate pump.
IMPORTANT NOTE: The evaporator coil is fabricated with oils that may dissolve styrofoam and certain types of plastics. Therefore, a removal pump or float switch must not contain any of these materials.
Tip: Priming the “P” trap may avoid improper draining at the initial installation and at the beginning of the cooling season.
This air handler is designed for a complete supply and return ductwork system.
CAUTION
DO NOT OPERATE THIS PRODUCT WITHOUT ALL THE DUCTWORK ATTACHED.
To ensure correct system performance, the ductwork is to be sized to accommodate 350-450 CFM per ton of cooling with the static pressure not to exceed 0.5” in w.c. Refer to ACCA Manual D, Manual S and Manual RS for information on duct sizing and application. Flame retardant ductwork is to be used and sealed to the unit in a manner that  will prevent leakage.
NOTE: A downflow application with electric heat must have an L-shaped sheet metal supply duct without any outlets or registers located directly below the heater.
9.1 Return Ductwork
DO NOT LOCATE THE RETURN DUCTWORK IN AN AREA THAT CAN INTRODUCE TOXIC, OR OBJECTIONABLE FUMES/ODORS INTO THE
DUCTWORK. The return ductwork is to be connected to the air handler bottom (upflow configuration).

 Return Air Filters

NOTE: For AMVT24BP1400** only: If installing a filter, an external filter must be used when installing the unit in Horizontal Right, or if the side drain pan is not removed for Down Flow application. A filter will not fit on the internal filter rails in these applications.
Each installation must include a return air filter. This filtering may be performed at the air handler using the factory filter rails or externally such as a return air filter grille. When using the factory filter rails, a nominal 16x20x1”, 20x20x1” or 24x20x1” (actual dimension must be less than 23-½”x20”) filter can be installed on a B, C and D cabinet
respectively (the cabinet size is the seventh letter of the model number).

Electric Heat

Refer to the installation manual provided with the electric heat kit for the correct installation procedure. All electric heat must be field installed. If installing this option, the ONLY heat kits that are permitted to be used are the HKS and HKTSD series. Refer to the air handler unit’s Serial and Rating plate or the HKS and HKTSD specification sheets to determine the heat kits compatible with a given air handler. No other accessory heat kit besides the HKS and HKTSD series may be installed in these air handlers.
The heating mode temperature rise is dependent upon the system airflow, the supply voltage, and the heat kit size (kW) selected. Use data provided in Tables 5, 6, AND 7 to
determine the temperature rise (°F).
NOTE: For installations not indicated above the following formula is to be used:
TR = (kW x 3412) x (Voltage Correction) / (1.08XCFM)
Where: TR= Temperature Rise kW
= Heater Kit Actual kW
3412 = Btu per kW
VC* = .96 (230 Supply Volts)
= .92 (220 Supply Volts)
*VC (Voltage Correction)
= .87 (208 Supply Volts)
1.08 = Constant
CFM = Measured Airflow
NOTE: The Temperature Rise Tables can also be used to estimate the air handler airflow delivery. When using these tables for this purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions. Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature minus the room air temperature. Using the temperature rise calculated, CFM can be estimated from the TR formula above. See Service Manual for more information.

Comfort Setting Menu Heater Kit Info
Comfort Setting Menu (CFS): There are 6 options available in the Comfort Setting Menu which impacts system target run time and electric heat functionality. Electric heat operation adjustments only apply if a communicating heat pump is installed. Comfort Setting Options 1 – 5 have set values for the System Target Runtime and option 6 enables additional menus to customize all comfort settings. See list below for the System Target Run times associated with the first 5 Comfort Settings. These first 5 options are setup to help satisfy the thermostat slower or faster based on the selection where option 1, with a 10 minute Target Runtime, is attempting to satisfy much faster than option 5, with a 30 minute Target Runtime.
System Target Runtime:
Comfort Setting Option 1) 10 Minute System Target Runtime
Comfort Setting Option 2) 15 Minute System Target Runtime
Comfort Setting Option 3) 20 Minute System Target Runtime
Comfort Setting Option 4) 25 Minute System Target Runtime
Comfort Setting Option 5) 30 Minute System Target Runtime
Electric Heat Adjustment: This system will automatically determine if the heat pump is capable of satisfying the thermostat in the selected System Target Runtime. If the heat pump is unable to satisfy in the selected time, electric heat settings will determine how many attempts should be given to the heat pump before temporarily locking it out and using the furnace. These electric heat settings also determine at what time the system should remove the temporary heat pump lockout and run the heat pump again. There are four adjustable items associated with back up electric heat operation control. In the same way as the System Target Time, each of these items have defaulted values for Comfort Settings 1 – 5. Only when Comfort Setting 6 is selected will each item be available for full adjustment.
Stage Up Percent (7 segment menu SUP): This is a value that determines how far past the target runtime the system should continue running the heat pump before transitioning to the furnace. For example, assume this menu was set to 20% with a target runtime of 20 minutes. If the thermostat did not remove the heating call after 20 minutes, the system would allow for an additional 20% heat pump run (20% of the 20 minute target is an additional 4 minutes). In this case, the system would turn on back up electric heat after 24 minutes if the thermostat call was still present. Each time this occurs, the system records this as a strike against the heat pump (the strike is important when looking at the Over Target Threshold).
Over Target Threshold (7 segment menu Ott): If the heat pump has consecutively activated back up electric heat for the selected Over Target Threshold amount of times, meaning for this many consecutive cycles it has been unable to satisfy the target time by itself, then the heat pump will be temporarily locked out and the furnace will become the primary heat source.
Stage Down Percent (7 segment menu SdP): This only applies when the heat pump and back up electric heat are activated on initial start-up. In this case, the system will try to determine when the best time to operate the heat pump individually again. To determine this, the system looks at how easily the air handler is able to satisfy the thermostat using the heat pump with back up electric heat. Assume this setting is 15% and the target time is 20 minutes If the heat pump with back up electric heat can satisfy the thermostat in less than 17 minutes (20 minutes – 15% = 17 minutes) then the algorithm records a strike against the air handler (this strike is important when looking at the Under Target Threshold).

*Airflows shown are to be considered the absolute minimum allowable for the Air handler and Heat kit combination. The minimum airflow does not represent the  recommended airflow by the manufacturer. When selecting a heater kit, the Minimum Blower Setting (M.B.S.) or speed tap listed on the unit’s nameplate should be followed.
Minimum CFM Required for Heater Kits
Table 10
Under Target Threshold (7 segment menu Utt): If the air handler is able to satisfy the thermostat using the heat pump with back up electric heat for the selected number of consecutive cycles the electric heat operation will be temporarily removed. The heat pump will then be used during the next cycle. If the heat pump can satisfy the thermostat in less than the System Target Runtime the back up heat operation will be completely removed and the heat pump will become the primary heat source again. If it fails to do so, the strike count against the furnace will be reset and the furnace will remain the temporary primary heat source until the Under Target Threshold is reached again.
The system will automatically make adjustments in an attempt to satisfy the thermostat as close to this target runtime as possible. After a power cycle or mode change (cooling to heating or heating to cooling) the system will run full capacity for the selected mode during the first thermostat call. Based on the selected target runtime and how long the initial cycle takes to satisfy the thermostat, the control algorithm will adjust the system stage times for a 2 stage unit or the capacity demand percentage for an inverter / modulating unit for the next cycle.

Quick Start Guide for Communication Outdoor Units

EXTREMELY IMPORTANT: For all cooling calls the system only requires a single Y input from the thermostat. For all heating calls (including applications with backup electric heater kits) the system only requires a single W input from the thermostat. Internal algorithms will control all available cooling and heating stages based on these inputs. Any single-stage 24VAC thermostat can be used. For proper operation, the thermostat must be setup to control a single stage AC outdoor unit and to control single stage electric heat operation. The control board does not accommodate an O wire thermostat input (reversing valve signal).
If a heat pump is installed, the thermostat should be setup as stated above. Setting the thermostat for the heat pump control or multistage control may result in incorrect performance.

1. Connect all necessary thermostat wires to the thermostat connector on the air handler control as instructed by the applicable wiring diagrams shown in this section.
2. Connect the 1 & 2 wires between the indoor and outdoor unit for communicating operation.
   NOTE: Verify two stage outdoor units include a 24VAC transformer (for outdoor control board power). Two stage outdoor units may not behave properly without this 24 VAC transformer.
3. Download the Cool Cloud HVAC phone application for charging and to configure / test system.

NOTE: When new versions of Bluetooth Communication Software and Air Handler Control Software are available, the phone application notifies the user. Software updates are classified as either optional or mandatory and installed by using the phone application. Ensure all mandatory software updates and install if necessary.
14.1 Charging

1. Two-stage outdoor units using the Cool Cloud HVAC application:
   a. Using the cooling icon after entering the outdoor unit menus, energize the outdoor unit at 49% capacity or lower.
   b. Charge the outdoor unit as required using the charging information provided with the outdoor equipment.

Quick Start Guide for Non-Communicating Outdoor Units
When setting up a Comfort Bridge air handler for use with a Non-Communicating outdoor unit you must set airflow in the “ton” menu on the PCB or in the Cool Cloud HVAC APP. Failure to do so will result in the air handler PCB displaying “IdL” and the blower will not operate with a call for cooling. The Board does not need to be replaced, you MUST set the airflow first.
EXTREMELY IMPORTANT: For two stage electric heat kit control the system only needs a single W input. Internal algorithms will control staging automatically based on the single W input. For non-communicating outdoor unit wiring, see instructions below:

1. Use the wiring diagrams on the next page to connect low voltage thermostat wires.
   NOTE: When installing the air handler with a noncommunicating heat pump, wire directly to the “O” terminal on the non-communicating heat pump. See the following figures.
2. Download the Cool Cloud HVAC phone application.
   NOTE: When new versions of Bluetooth Communication Software and Air Handler Control Software are available, the phone application notifies the user. Software updates are classified as either optional or mandatory and installed by using the phone application. Ensure all mandatory software updates have been installed. Review notes for optional software updates and install if necessary.
3. Go to the Non-Comm Outdoor Setting Menu () using the on board push buttons or the Cool Cloud HVAC phone application. Select “” for single stage Air Conditioners, “” for single stage Heat Pumps, “” for two stage Air Conditioners and “” for 2 stage Heat Pumps.
4. Go to the Tonnage Units Menu () and select the tonnage value that corresponds to the desired airflow for the outdoor unit. See the following table.
   NOTE: For the two stage non-communicating outdoor units, system will stage airflow automatically for low stage operation.

2. Select any value less than 50% for low stage operation and any value greater than 50% for high stage operation.
3. Confirm thermostat heating and cooling calls function properly for high stage operation.

Table 15

Dehumidification

Dehumidification allows the air handler’s circulator blower to operate at a reduced speed during a combined thermostat call for cooling and a dehumidification call from the thermostat or humidistat. This lower blower speed increases dehumidification of the conditioned air as it passes through the indoor coil. The control board is equipped with a 24 volt dehumidification input (DH) located on the thermostat wiring connector. The terminal can be configured to enable dehumidification when the input is energized or de-energized. When using an external Dehumidistat, connect it between the R and DH terminals. If the humidistat closes on humidity rise or the thermostat energizes this terminal when dehumidification is required, set the control board Dehu Logic Menu () to “” using the push buttons or Cool Cloud HVAC phone application. If the humidistat opens on humidity or the thermostat deenergizes this terminal when dehumidification is required, set the Dehu Logic Menu to “” using the push buttons or Cool Cloud HVAC phone application.

Auxiliary Alarm Switch

The control is equipped with a 24VAC Aux Alarm to be used for a condensate switch install (designated by CONDENSATE IN/OUT on the control). By default, the
connected AUX switch is normally closed and opens when the water level in the evaporator coil base pan reaches an undesirable level. The control responds by displaying
a “” error code and turning off the outdoor condensing unit. If the AUX switch is detected to be in the closed position for 30 seconds, normal operation resumes and the error message is no longer displayed.

Start-Up Procedure

The air handler includes three on-board push buttons allowing users to navigate indoor and outdoor system menus. The Right and Left buttons allow the user to scroll through the main menus and to then scroll through available options within specific menus. The Center button is used to enter into a main menu and to then permanently
select options within those menus.
NOTE: After scrolling to the desired option within a menu, that option may be flashing on the 7-segment displays. This indicates the option has not been officially selected. Pressing the Center button two times will select that option. The first press will stop the flashing. The second will make the selection official and return you to the main menu.

Accessory Control (Humidifiers, Dehumidifiers, Ventilators)

If an external humidifier, dehumidifier or ventilator is installed, it may require airflow from the HVAC system to function properly.

1. Make sure the installed 24VAC thermostat is capable of controlling the accessory or accessories.
2. Connect the appropriate accessory control wires to the accessory devices from the thermostat (see thermostat manual for connection and setup instructions).
3. If the thermostat is capable of providing a continuous fan call (G signal) during accessory operation: Make sure to connect the thermostat G terminal to the G terminal on the indoor unit. Setup thermostat to ensure G signal is energized during accessory operation.
4. Select the appropriate fan only airflow for the accessory using the indoor unit push button menus or the Cool Cloud HVAC phone application.
5. Using the thermostat, independently test each accessory in addition to the independently testing continuous fan mode.

Dehumidification Control Options

Key Mitigations:

1. Full featured TS (degum & overcool)
2. Connect G and degum wire correctly
3. Dehumidistat

Ramping Profiles

The variable-speed circulator offers four different ramping profiles. These profiles may be used to enhance cooling performance and increase comfort level. Select the desired
ramping profile using the Cool Cloud phone application or the push button menus.

• Profile A provides only an OFF delay of one (1) minute at 100% of the cooling demand airflow.
• Profile B ramps up to full cooling demand airflow by first stepping up to 50% of the full demand for 30 seconds. The motor then ramps to 100% of the required airflow. A one (1) minute OFF delay at 100% of the cooling airflow.
• Profile C ramps up to 82% of the full cooling demand airflow and operates there for approximately 7 1/2 minutes. The motor then steps up to the full demand airflow. Profile C also has a one (1) minute 100% OFF delay.
• Profile D ramps up to 50% of the demand for 1/2 minute, then ramps to 82% of the full cooling demand airflow and operates there for approximately 7 1/2 minutes. The motor then steps up to the full demand airflow. Profile D has a 1/2 minute at 50% airflow OFF delay.

Electric Air Cleaner Warning

The control is equipped with an Accessory Relay and a pair of ¼ inch accessory terminals which is normally open, labeled EAC-IN and EAC-OUT (see accessory contacts graphic). The Accessory Relay is configured to close anytime the blower is running. A closed relay means the two terminals will have continuity between them (the control
does not energize these contacts). It is recommended to utilize 24VAC with these terminals and limit the current to 1A.

Achieving 1.4% Low Leakage Rate
Ensure all the gaskets remain intact on all surfaces as shipped with the unit. These surfaces are areas between the upper tie plate and blower access panel, blower access and coil access panels, and between the coil access and filter access panels. Ensure upon installation, that the plastic breaker cover is sitting flush on the blower access panel and all access panels are flush with each other and the cabinet. With these requirements satisfied, the unit achieves less than 1.4% airflow leakage when tested in accordance with ASHRAE Standard 193.

AIR HANDLER
AIR HANDLER HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
An indoor air filter must be used with your comfort system.
A properly maintained filter will keep the indoor coil of your comfort system clean. A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your air conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters should be replaced. Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types. These filters can do a better job of catching small airborne particles.
Motors
Indoor and outdoor fan motors are permanently lubricated and do not require additional oiling.
WARNING
HIGH VOLTAGE
DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
ALUMINUM INDOOR COIL CLEANING
(QUALIFIED SERVICER ONLY) This unit is equipped with an aluminum tube evaporator coil. The safest way to clean the evaporator coil is to simply flush the coil with water. This cleaning practice remains as the recommended cleaning method for both copper tube and aluminum tube residential evaporator coils.
It has been determined that many coil cleaners and drain pan tablets contain corrosive chemicals that can be harmful to aluminum tube and fin evaporator coils. Even a onetime application of these corrosive chemicals can cause premature aluminum evaporator coil failure. Any cleaners that contain corrosive chemicals including, but not limited to, chlorine and hydroxides, should not be used. An alternate cleaning method is to use one of the products listed in TP-109* to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils. TP-109 is also available on the web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical cleaners.
CAUTION
TO AVOID THE RISK OF EQUIPMENT DAMAGE OR FIRE, INSTALL THE SAME AMPERAGE BREAKER OR FUSE AS YOU ARE REPLACING. IF THE CIRCUIT BREAKER OR DUSE SHOULD OPEN AGAIN WITHIN THIRTY DAYS, CONTACT A QUALIFIED SERVICER TO CORRECT THE PROBLEM.
IF YOU REPEATEDLY RESET THE BREAKER OR REPLACE THE FUSE WITHOUT HAVING THE PROBLEM CORRECTED, YOU RUN THE RISK OF SEVERE EQUIPMENT DAMAGE.

BEFORE YOU CALL YOUR SERVICER

• Check the thermostat to confirm that it is properly set.
• Wait 15 minutes. Some devices in the outdoor unit or in programmable thermostats will prevent compressor operation for awhile, and then reset automatically. Also, some power companies will install devices which shut off air conditioners for several minutes on hot days. If you wait several minutes, the unit may begin operation on its own.
• Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses as necessary.
• Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.
• Check for obstructions on the outdoor unit. Confirm that it has not been covered on the sides or the top. Remove any obstruction that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.
• Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs, curtains or furniture).
• Check the filter. If it is dirty, clean or replace it.
• Listen for any unusual noise(s), other than normal operating noise, that might be coming from the outdoor unit. If you hear unusual noise(s) coming from the unit, call a qualified servicer.
