Coates PHS SERIES 54 & 480V - Manual (Page 3)

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).

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.
