IMPORTANT SAFETY INSTRUCTIONS
When using this electrical equipment, basic safety precautions should always be followed, including the
following.
1) READ AND FOLLOW ALL INSTRUCTIONS.
2) To reduce the risk of injury.
A) The water in a pool or tub should never exceed 104°F (40°C). A water temperature in excess of
104°F is considered unsafe for all persons. Lower water temperatures are recommended for
extended use (exceeding 10-15 minutes) and for young children.
B) Since excessive water temperatures have a high potential for causing fetal damage during the
early months of pregnancy, pregnant or possibly pregnant women should limit pool or tub water
temperatures to 100°F (38°C).
C) Before entering a pool or tub, the user should measure the water temperature at several occupant
locations using an accurate thermometer since the tolerance of water temperature-regulating
devices may vary as much as ± 5°F (± 3°C).
D) Alcohol, drugs or medications should not be used before or during pool or tub use since their use
may lead to unconsciousness with the possibility of drowning.
E) Obese persons and persons with a medical history of heart disease, low or high blood pressure,
circulatory system problems, or diabetes should consult a physician before using a pool or tub.
F) Persons using medication should consult a physician before using a pool or tub since some
medication may induce drowsiness while other medication may affect heart rate, blood pressure,
and circulation.
3) SAVE THESE INSTRUCTIONS.
---WARNING---
DANGER OF HYPERTHERMIA
Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above
the normal body temperature of 98.6°F. The symptoms of hyperthermia include dizziness, fainting,
drowsiness, lethargy and an increase in the internal temperature of the body. The effects of hyperthermia
include:
a) Unawareness of impending hazard;
b) Failure to perceive heat;
c) Failure to recognize the need to exit pool or tub;
d) Physical inability to exit pool or tub;
e) Fetal damage in pregnant women;
f ) Unconsciousness resulting in a danger of
drowning.
WARNING--- The use of alcohol, drugs or medications can greatly increase the risk of fatal
hyperthermia in pools and tubs.

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:
(1) The heating elements; mounted on a four-bolt
flange. There are 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 will
activate at flow rates of 20 GPM or greater.
(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:

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.
Page 3

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.
If the high temperature manual reset high limit switch
shuts off the heater, disconnect power at disconnect
switch and determine the cause before resetting.

The company extends this limited warranty to the original purchaser of a Coates Electric Pool Heater.
Coates warrants the electrical components* and wiring (excluding enclosure, enclosure parts, knobs and accessories) in this

or eighteen (18) months from date of factory shipment, whichever occurs first. Coates further warrants the stainless steel
water containment vessel to be free from defects in materials and workmanship for two (2) years from the provable date of
purchase or thirty (30) months from the factory shipment, whichever occurs first. Enclosure, enclosure parts, knobs and
accessories have no warranty whatsoever.
*Exception: Factory installed heating elements are warranted for ninety 90 days from the date of heater installation, or
eighteen (18) months from date of factory shipment, whichever occurs first.
COATES will repair or replace at its option, defective component parts as explained above, during the warranty period
provided such parts are returned to the factory, freight prepaid. Factory authorization MUST BE OBTAINED under this
warranty before returning such defective parts.
Limited Warranty Does Not Cover
1. New products purchased outside the United States of America and Canada.
2. Uncrating, unpacking, set-up, installation and / or startup of this unit.
3. Adjustments to controls normally operated by consumer, purchaser or installer.
4. This limited warranty does not extend to any defect, malfunction or failure caused by, or resulting from improper
service, maintenance or repair, abuse, neglect, accident, corrosion caused by improper water chemistry or by
equipment that use salt to create a sanitizer, lack of water, or any other cause beyond the control of Coates
Heater Company, Inc. or to any product where the nameplate shall have been removed, altered, replaced, defaced or
rendered illegible.
5. This limited warranty is void if the Heater is used in a salt water system or under any extreme or unusual
corrosive condition for which stainless steel metals would not be recommended.
6. This limited warranty does not extend to the repair or replacement of defective components except at COATES or a
service facility authorized by COATES
IMPLIED WARRANTIES, WHEN APPLICABLE, SHALL COMMENCE UPON THE SAME DATE AS THE EXPRESS
WARRANTY PROVIDED ABOVE, AND SHALL, EXCEPT FOR WARRANTIES OF TITLE, EXTEND ONLY FOR
THE DURATION OF THE EXPRESS WARRANTY. SOME STATES DO NOT ALLOW LIMITATIONS ON HOW
LONG AN IMPLIED WARRANTY LASTS, SO THE ABOVE LIMITATION MAY NOT APPLY TO YOU. THE ONLY
REMEDY PROVIDED TO YOU UNDER AN APPLICABLE IMPLIED WARRANTY AND THE EXPRESS
WARRANTY SHALL BE THE REMEDY PROVIDED UNDER THE EXPRESS WARRANTY, SUBJECT TO THE
TERMS AND CONDITIONS CONTAINED THEREIN.
COATES SHALL NOT BE LIABLE FOR INCIDENTAL AND CONSEQUENTIAL LOSSES AND DAMAGES, UNDER
THE EXPRESS WARRANTY, ANY APPLICABLE IMPLIED WARRANTY, OR CLAIMS FOR NEGLIGENCE,
EXCEPT TO THE EXTENT THAT THIS LIMITATION IS FOUND TO BE UNENFORCEABLE UNDER APPLICABLE
STATE LAW.
