INTRODUCTION
This manual provides installation procedures, operating and maintenance instructions and a parts list for the Coates Pool Heater.
Your Coates Electric Swimming Pool Heater has been designed and engineered to provide you with the most progressive quality heating system possible. Its operation is efficient and pollution-free. Models are available for every size or make of pool.
To insure a long life of trouble-free service, your Coates Pool Heater should be carefully installed in accordance with the instructions given in this manual. Failure to do so may damage the pool heater and the pool equipment to which it is connected. Only qualified personnel should install and maintain this unit, and, of course, local plumbing and electrical codes have precedence over these instructions.
1.0 DESCRIPTION
The Coates Swimming Pool Heater consists of a heating tank with external enclosure, and the electrical heating and control system. In order to help maintain the heater in a satisfactory manner, a brief description of its components and their operation is included for the customer’s convenience.
The pressure vessel and its enclosure comprise the main mechanical portion of the pool heater.
The pressure vessel, in conjunction with the pressure switch and heating element are the only portions of this equipment in contact with the water.
The external enclosure is a sheet steel case totally enclosing the pressure vessel and electrical components. The enclosure is coated with a rust inhibiting, powder coat finish.
The electrical system, which is the heart of this unit, can be considered as three separate systems engineered to provide optimum use of energy. They are as follows:

(1) The heating elements; mounted on a four-bolt flange. There are 1, 2, 3 or 4 elements.
(2) The control system; consists of the pilot switch, high limit thermostat, flow switch, temperature control, magnetic contactors, 240V transformer (480V units only) and sequencer (on some single phase units only). These controls are wired into a control circuit designed to control the temperature of the water leaving the heater. The high-limit thermostat is designed to open the control circuit and cut off the power in the event of excessive temperature.
A flow switch is built-in to prevent the pool heater from operating without water flow. The flow switch is designed for a minimum of 20GPM.
(3) The main current-carrying components; are the contactors and fuses. These are wired into circuits which carry the full amperage draw of the elements. The contactors open during a high temperature condition to de-energize the elements.
The element fuses in these units are rated at 60 Amps and have an interrupting capacity of 100,000 Amps rms. These fuses provide supplemental circuit protection for the internal wiring of the heater.
The heater has a temperature controller adjustable up to 104°F(40°C) and has one manual reset type high temperature limit thermostat set at 118°F (48°C).

2.0 LOCATION AND PLUMBING

A. Installation: Location

Coates swimming pool heaters are quiet, do not expel exhaust fumes, and may be conveniently located in a shed or basement. Normal positioning of the pool heater should be in close proximity to the pool filtration system. Select a location conveniently close to incoming electrical service and where excessively long piping runs are not required.

Minimum clearance:

Front Left Right Top Back

PHS 36 (914)# 18 (457)
* 18 (457) 6 (153)

* Required clearance is based on plumbing configuration used. # Refer to NEC Table 110.26 (A)(1) – Dimensions: Inches (mm) – Temperature control is located on the front side.

B. Installation: Plumbing
Pipe the heater as shown in Figure 2 to the inlet and outlet openings on the right side. Connect the heater in line between the filter discharge and pool. The water line coming from the filter should be connected to the heater inlet, and the discharge line to the pool should be connected to the outlet. The pool will not heat properly unless it is plumbed correctly. If plastic pipe is used, it should be suitable for at least 120°F (49 °C).
A plumbing bypass around the pool heater is not necessary unless flow rate though the heater exceeds 80 GPM. A minimum flow rate of 20 GPM is required. Lack of sufficient flow will not allow the flow switch to activate the heater.
It may be necessary, in larger Olympic-sized or public pools, to use two or more heaters to obtain sufficient KW capacity. If so, the heaters must be placed in parallel, so that each heater takes equal flow.
DRAINAGE: A method of draining water away from the heater and other equipment is to be provided. The heater should be flushed at the end of each swimming season. During flushing or service, water may be spilled and could cause damage to the floor or other equipment. A drain valve is to be installed in the INLET plumbing.
3.0 ELECTRICAL INSTALLATION
1.Check nameplate rating to insure the heater matches your electrical supply.
2.CHECK ELECTRICAL CONNECTIONS TO ALL COMPONENTS within the heater for tightness. These can become loose during shipment and handling.
3.Check components for any moisture, rust, or dust which may have accumulated during shipping, and clean or dry where necessary.
All pool heaters covered in this manual have integral thermostats, transformers, contactors and sequencers where required.
Wiring diagrams included show internal wiring and required field connections for various models. Consult your local electrical code for proper wire and conduit sizes, and other local requirements.
Do not connect the pool heater to, or operate at, a voltage other than the voltage rated on the nameplate.
Bring wires of adequate size from a fused disconnect switch or circuit breaker with an ampere rating of 125% of the ampere rating shown on heater nameplate. Refer to Table 1 for wire sizes. Connect power conductors to the power distribution block inside

the heater. All other internal connections are completed and tested at the factory.

Ground wires must be insulated copper conductor and the same size as supply wiring, but not less than #12 AWG.

A. To Connect Pool Heater to Power Supply

The pool heaters with load ratings over 48 Amps have branch supplemental fusing already installed in the element circuitry; see wiring diagrams. To connect to the power supply, one needs only to protect the main supply lines, either with a circuit breaker or fused disconnect switch (Figure 1). Suggested wire sizes are shown in Table 1.

Figure 1
B. Startup Procedure:
1. Make sure that the pump is on and that there is at least 20 GPM flow through the pool heater. The heating elements will fail prematurely if allowed to operate with insufficient water flow.
2. Check temperature control setting, also, examine wiring for loose connections, etc.
3. Turn on power at main disconnect switch.
4. Turn on pilot switch on pool heater.
5. Adjust temperature control to desired water temp.
If the high temperature manual reset high limit switch shuts off the heater, disconnect power at disconnect switch and determine the cause before resetting.

DIGITAL THERMOSTAT CONTROL

For heaters equipped with a digital thermostat. The

digital thermostat control which measures the

temperature of the water as it enters the heater has a

MENU button, up and down adjustment buttons, and

an LED display. The desired water temperature (set

point) is controllable between 40°F and 104°F (5°C

and 40°C). The set point may differ from the actual

water temperature at the pool or spa due to heat loss

in the piping.

MENU: The MENU button cycles through the three menu items: Measured Water Temperature (default), SET POINT and °F/°C.

ADJUSTING THE SET POINT:
Press one of the following buttons; MENU, or .
The display will momentarily blank and then the current set point will be displayed. Press the or button to change the set point. Hold the button down for rapid temperature changes.

The set point will be saved and the display will return to the measured temperature after two seconds of inactivity.

FAHRENHEIT TO CELCIUS: Press the MENU button twice and the current temperature scale will be displayed ( F or C ). Press the
or buttons to toggle between F and C.

The temperature scale will be saved and the display will return to the measured temperature after two seconds of inactivity.

ERROR CODE: The display will read “Err” when it detects a problem with the temperature sensor. This can be caused by a faulty sensor or a loose connection between the sensor and the temperature controller.

DIAL THERMOSTAT CONTROL

For heaters equipped with an analog dial thermostat.

The thermostat measures the temperature of the water

as it enters the heater. The desired water temperature

(set point) is controllable between 70°F and 104°F (21°C

and 40°C). The set point may differ from the actual

water temperature at the pool or spa due to heat loss in

the piping.

5.0 MAINTENANCE

Element Inspection and Replacement: 1. Turn off power at main disconnect switch and turn
off pump. 2. Drain pool heater. 3. Remove service access panel opposite inlet/outlet. 4. Disconnect element wires. 5. Remove the four (4) element flange retaining nuts
