WARNING
Only qualified personnel, as defined by National
Electric Code Article 100, should install and
maintain this equipment. Unauthorized alteration
or improper maintenance of this unit may release
the manufacturer from any warranty claims. The
installation must be in accordance with the
instructions in this manual and applicable local
plumbing and electrical codes.
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 flow
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:
2
(1)
The heating elements; mounted on a four-bolt
flange. There are either 2, 3 or 4 elements.
(2)
The control system; consists of the pilot switch,
high limit thermostat, flow switch, temperature control,
magnetic contactors and transformer. These controls
are wired into a 120V or 220V 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 will
activate at flow rates of 20 GPM (1.26 L/sec) or greater.
(3)
The main current-carrying components; are
the contactors. These are wired into circuits which carry
the full amperage draw of the elements. The contactors
function during a high temperature condition to deenergize the elements.
The heater has a temperature controller adjustable from
70°F(21°C) to 104°F(40°C) and has one manual reset
type high temperature limit thermostat set at 122°F
(50°C).

LOCATION AND PLUMBING
A.
Installation: Location
Coates swimming pool heaters are quiet, do not expel
exhaust fumes, and may be conveniently located in 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.

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 122°F
(50 °C).
Ground wires must be insulated copper conductor and
the same size as supply wiring, but not less than #12
AWG (4 mm2).

A plumbing bypass around the pool heater is not
necessary unless flow rates though the heater exceed
80 GPM (5 L/sec). A minimum flow rate of 20 GPM
(1.26 L/sec) 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.
Suggested size for insulated copper conductor
wires. Based on 125% correction factor for wire
with 90°C insulation.

ELECTRICAL INSTALLATION
First:
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.
To Connect Pool Heater to Power Supply
These pool heaters 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.
or
All pool heaters covered in this manual have integral
thermostats, transformers, contactors and sequencers
where required.
All other internal connections are completed and
tested at the factory.

Wiring Diagram: Single-Phase Models
Wiring diagrams on pages 6 through 14 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.
or
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
the power conductors to bus assembly on inside of the
heater.

Startup Procedure:
4.0
1. Make sure that the pump is on and that there is at
least 20 GPM (1.26 L/sec) flow through the pool
heater. The heating elements will fail if allowed to
operate dry.
MAINTENANCE
Element Inspection and Replacement:
1. Turn off power at main disconnect switch and turn
off water at water supply line.
2. Drain pool heater.
3. Remove left end service access panel.
4. Disconnect element leads.
5. Remove the four (4) element flange retaining nuts
and extract element.
6. Installation is the reverse of steps 1 through 5.
(Reinstall element with new gasket)
2. Check temperature control setting, also, examine
wiring for loose connections, etc.
3. Set temperature control to the desired
temperature.
Note: for each degree the
temperature control setting is increased, power
usage may increase up to 10%.
Semi-Annual Cleaning:
Accumulated sludge in the tank is the greatest cause of
element failure. Twice yearly (before summer start-up
and before winter), the pool heater should be drained
and cleaned to remove any scale or sludge. More
frequent cleaning may be required if pool water contains
sediment or any amount of foreign matter.
1. Turn off system at main disconnect switch.
2. Open drain valve.
3. Permit water to run until it is clear.
4. Close valve and restart normally.
4. Turn on power at main disconnect switch.
5. Turn on pilot switch on pool heater.
When closing down the pool for any length of time,
shut off the power at the main disconnect switch and
drain the water from the system. Water must not be
allowed to freeze in the heater, as this will cause
severe damage.
If high temperature causes manual reset high limit
switch to shut off the heater, disconnect power at
disconnect switch and determine the cause before
resetting.
PROTECT ING YOUR COAT ES HEAT ER

Proper water balance is important to extending the life of your Coates
Heater. While pH control is critical, the control of alkalinity and calcium
hardness will protect against scaling and also help to prevent corrosion.
