to ensure proper drainage. If the secondary drain line is required, run the line separately from the primary drain and end it where it can be easily seen. NOTE: Water coming from this line means the coil primary drain is plugged and needs clearing.
CAUTION

Installation Clearances
Place this unit as close to the space to be air conditioned as possible. These units are U.L. listed for installations with zero clearance to combustible materials. If this unit is installed in a removable ceiling panel, ensure adequate space is available for servicing. Run ducts as direct as possible to supply and return outlets. Use nonflammable weatherproof flexible connectors on both supply and return connections at unit to reduce noise transmission.
Ducting
Duct work should be fabricated by the installing contractor in accordance with local codes. Use industry manuals such as such as NESCA (National Environmental Systems Contractors Association, 1501 Wilson Blvd., Arlington, Virginia 22209) as a guide when sizing and designing the duct system.

If secondary drain is not installed, the secondary access must be plugged.
The installation must include a “P” style trap that is located as close as is practical to the evaporator coil. See Figure 1 for details of a typical condensate line “P” trap.
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. In a blow-through application the drain trap prevents conditioned air from escaping. It is permissible in this application to use a shallow trap design sometimes referred to as a running trap.
Drain Connection

To ensure correct system performance, the ductwork is to be sized to accommodate 375-425 CFM per ton of cooling with the static pressure not to exceed 0.5″ W.C. Inadequate ductwork that restricts airflow can result in improper performance and compressor or heater failure.
WARNING

To prevent possible equipment damage, property damage, fire, carbon monoxide poisoning, explosion, personal injury or death, do not connect ductwork to any heat producing device such as a fireplace insert or stove.
Filters
Filters are not provided with unit, and must be supplied and installed in the return air system by the installer. A field installed filter grille is recommended for easy and convenient access to the filters for periodic inspection and cleaning. Filters must have adequate face area for the rated air quantity of the unit. The minimum filter size is 20″ x 20″ x 1″.
Condensate Drain Piping
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 approximately 37 in-lbs. to prevent damage to the drain pan connection. An insertion depth between .143 to .355 inches (2-5 turns) should be expected at this torque. Use the female (3/4 NPT) threaded fitting that protrudes outside of the enclosure for external connections.
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 Armaflex® or similar material.
A Secondary Condensate Drain Connection has been provided for areas where the building codes require it. Pitch the drain line 1/4″ per foot to provide free drainage. Insulate drain lines located inside the building to prevent sweating. Install a condensate trap

Figure 1 The depth of a running trap (Figure 2) should be either 1″ or a depth that permits unrestricted condensate drainage without excessive air discharge. Field experience has shown condensate drain traps with an open vertical Tee between the air handler and the condensate drain trap can improve condensate drainage in some applications, but may cause excessive air discharge out of the open Tee. We do not prohibit this type of drain but we also do not recommend it due to the resulting air leakage. Regardless of the condensate drain design used, it is the installer’s responsibility to ensure the condensate drain system is of sufficient design to ensure proper condensate removal from the coil drain pan.

Figure 2
When coils 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. Drain lines from the auxiliary pan must be installed and terminated so that the homeowner can see water discharges. A primary condensate drain connection is located in the drain pan on the bottom of the coil / enclosure assembly. The female (3/4 fpt) threaded fitting that protrudes outside of the enclosure is used for external connections.

LAYOUT FOR CEILING MOUNT AIR HANDLERS
NOTE: These air handlers are designed for indoor installation only at a max altitude of 10,500 feet above sea level or a min altitude of -184 feet below sea level.

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 casing. On these installations, a wrap of 2″ fiberglass insulation with a vapor barrier is recommended. A secondary drain pan below the unit is also recommended to protect
the installation site.

Figure 5 IMPORTANT: Installation of Air Handler must follow any local codes/regulations. The manufacture recommends that when a heater kit is not installed, a field supplied disconnect switch or breaker should be installed in the electrical circuit that will allow power to be shut-off for service or maintenance.
SPECIAL INSTRUCTIONS
This air handler comes equipped with an evaporator coil with a check style flowrator assembly, an indoor blower and all necessary internal electrical wiring. Remove the piston from the flowrator. For the rated performance a Thermal Expansion Valve (TXV) is required. Follow the instruction below for TXV installation and adjustment procedure.
WARNING
The evaporator coil is shipped from the factory with approximately 120 PSI tracer gas charge. Use caution when relieving pressure.
IMPORTANT NOTE: Torch heat required to braze tubes of various sizes is proportional to the size of the tube. Tubes of smaller size require less heat to bring the tube to brazing temperature before adding brazing alloy. Applying too much heat to any tube can melt the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed. NOTE: The use of a heat shield when brazing is recommended to avoid burning the serial plate, insulation or the finish on the unit. Heat trap or wet rags should be used to protect heat sensitive components such as service valves and TXV valves. Use insulation present in the service kit to prevent condensation on the TXV.
Tubing Connections Note: The TXV must be adjustable to meet the outdoor unit’s target superheat value. During the superheat adjustment on the TXV, the torque applied on the nut cannot exceed 25 in-lbs. Refer to the EXPANSION VALVE TROUBLESHOOTING section of this manual for assistance with the adjustable TXV.

1. Remove the valve core to allow high pressure tracer gas to escape. No gas indicates a possible leak.
2. Remove the 13/16″ flare nut and tailpiece. 3. Unsweat the access fitting on the tailpiece 4. Remove the check piston and install the appropriate TXV. See
the TXV service kit for instructions. 5. Unsweat the cap on the suction line. 6. Slide the 13/16″ flare nut over the tailpiece. 7. Braze tailpiece to the lineset liquid tube. 8. Insert the suction line into the connection, slide the insulation
at least 18″ away from the braze joint. Braze suction line. 9. AFTER THE TAILPIECE HAS COOLED, confirm position of the
white Teflon® seal and hand tighten the 13/16″ flare nut. 10. Torque the 13/16″ flare nut to 7-25 ft-lbs. or tighten 1/6 of a
turn. Do not overtighten.
CAUTION
Excessive torque can cause orifices to stick. Use the proper torque settings when tightening orifices.
11. Replace suction line insulation. 12. After installation, evacuation and charging of the low side is
complete, check fittings for leaks.
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 0.3″ WC or less. 2. Airflow is correct for the 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 termostat 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. Befor checking superheat run the unit 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.

1. Purge gauge lines. Connect service gauge manifold to basevalve 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 themometer makes adequeate 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. 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. 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 thatn 1/4 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 Scrader ports for leaks and tighten valve cores if necessary. Install caps finger tight.

MAINTENANCE
Room Thermostat
The room thermostat controls the operation of your heating and/ or cooling unit. It senses the indoor temperature and signals the equipment to start or stop maintaining the temperature you have selected for your comfort. The room thermostat should be in a central, draft free inside wall location for best operation. Do not place any heat producing apparatus such as lights, radio, etc., near the thermostat as this will cause erratic operation of the comfort system.
Air Filter(s)
All central air moving comfort systems must include air filter(s). Locate these filters in either the equipment or return air duct system upstream of the equipment. The filter(s) removes dust and debris from the air thus helping to keep your conditioned space clean. More important, the filter keeps dust and debris from collecting on heat transfer surfaces thus maintaining optimum equipment efficiency and performance. Inspect and clean or replace filters every month. This routine maintenance procedure will pay big dividends in reduced operating cost and reduced service expense. Never operate comfort equipment without filter(s).
Fuses and/or Circuit breakers
This comfort equipment should be connected to the building electric service in accordance with local and National Electric codes. This electrical connection will include over current protection in the form of fuses or circuit breakers. Have your contractor identify the circuits and the location of over current protection so that you may be in a position to make inspections or replacements in the event the equipment fails to operate. Keep replacement fuses of the proper size on hand.

The primary limit and the backup protection device on ther electric heating element are the two components that can be replaced.

Periodic Checkup and Service
This unit is designed to provide many years of dependable, troublefree comfort when properly maintained. Proper maintenance will consist of annual checkups and cleaning of the internal electrical and heat transfer components by a qualified service technician. Failure to provide periodic checkup and cleaning can result in excessive operating cost and/or equipment malfunction.

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 one-time 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.

Heater Kit Service

This comfort equipment comes pre-installed with a UL 2-40 certified heater kit. In times of replacement, please ensure that only a UL 2-40 certified kit is utilized.

NOTE:
1. Airflow data indicated is at 230V without air filter in place.
2. Select a speed tap that provides a minimum 300 CFM per outdoor ton. For satisfactory operation, external static pressure must not exceed 0.3″WC ( for electric heater only).

Expansion Valve Troubleshooting Before replacing an expansion valve, check the following items:
1. Bulb location: Must be tightly securred to the suction line upstream of the equalizer connection.
2. Insulation: Bulb must be properly insulated. 3. Equalizer: Must be connected to the 1/4: SAE connection on
the suction line. 4. Charge: Ensure the system is properly charged. there MUST
be a minimum of 10°F Sub-Cooled liquid at the valve inlet. If the system appears to be “starving” (low suction pressure but insufficient cooling):
1. Check the Superheat (SH) at the evaporator outlet. If SH is between 5°F – 12°F the TXV is controlling properly. -Verify that there is proper airflow to the evaporator (fan is operating and filter is unrestricted).
2. If SH is above 12°F, the setting of the TXV may be too high. -Adjust the SH by turning counter-clockwise to decrease SH. -Wait 20 minutes for the system to balance and adjust again, as required. -If adjusting the valve has no effect on the SH, the valve may be stuck because of dirt debris or it may have lost the Power Element charge.
i. After properly reclaiming the refrigerant, remove the TXV and check for dirt and debris. Clean, if possible, or replace the TXV and filter/drier.

If the system appears to be “flooding”(compressor frosting or moisture is condensing at the suction connection):
1. Check the SH at the evaporator outlet. If SH is between 5°F – 12°F, the TXV is controlling properly.
2. If SH is less than 5°F, the SH adjustment may be too low. -Adjust the SH by turning the adjustment stem clock-wise to increase the SH. -Wait 20 minutes for the system to balance and adjust again as required. -If adjusting the valve has no effect on the SH, the valve may be stuck open because of dirt of debris or moisture in the refrigerant.
i. After properly reclaiming the refrigerant, remove the TXV and check for dirt and debris. Clean, if possible, or replace the TXV and filter/drier. Add a moisture indicator to allow checking of moisture if this believed to be a probable cause.
