Automatic Chlorinators
and Chemical Feeders
All chemicals must be introduced and completely diluted in
the pool or spa water before being circulated through the
heater. Do not place sanitizing chemicals in the skimmer.
High chemical concentrations will result when the pump is
not running (e.g. overnight).

3. BEFORE INSTALLATION
WARNING: This heat pump pool heater is an
A
electromechanical
machine
pressurized refrigerant gas in a sealed system. ONLY
trained and qualified service personnel are authorized to
install or service this equipment. Without proper training
and knowledge of such equipment, any attempt to install
or service the unit could result in serious injury or even
death.
This manual contains important information on the use,
maintenance and troubleshooting of your new heater. This
unit must be properly installed, maintained and operated
for optimal performance.
This heater is an extremely efficient, economical machine
designed specifically for pool heating. It is similar in design
and operation to a typical residential air conditioning
system. The unit employs a hermetic motor/compressor
operating in a refrigeration cycle to extract heat from
ambient air and deliver it to the circulating pool water.
All heat pump pool heaters have a lower BTU/hr heating
capacity than a gas-fired or oil-fired heater for the same
pool and will have to operate more hours per day to keep
the pool at setpoint. It may operate up to 24 hours a day
at certain times. It is designed to do so. Even with long
runtime hours, it will heat the pool at less cost than other
heaters using fossil fuel.

Chlorinators must feed downstream of the heater and
have an anti-siphoning device to prevent chemical backup
into the heater when the pump is shut off.
See plumbing diagrams starting with Figure 9.
NOTE: High chemical concentrates from feeders
and chlorinators that are out of adjustment will cause
rapid corrosion to heat exchanger. Such damage is not
covered under the warranty.

Since evaporation is the main cause of heat loss from a
pool, keeping the pool covered whenever it is not in use will
greatly reduce the cost of keeping the pool heated. Even
during warmer weather, Raypak recommends keeping the
pool covered at night.
INSTALLATION
Installation Considerations
Locate the heater carefully to minimize installation costs
while providing maximum efficiency of operation, and to
allow adequate service access, as follows:
For unrestricted air intake and service access, position
each side of the unit according to Figure 2.
A
WARNING: This unit is designed for outdoor
installation. It is NOT certified for indoor installation.
DO NOT install it in an enclosed area such as a shed or
garage, or under a porch or deck.
To minimize water piping, locate the unit as close as
possible to the existing pool pump and filter.
Irrigation water should be directed away from the heater as
irrigation water spray can damage the heater.
Rain water runoff - the unit is designed to operate outdoors
and can be exposed to rain. However, rain water run off
falling directly onto the unit can cause damage and/or
shorten the life of your unit. Such damage is not covered
under warranty. Install rain gutters or rain diverters on your
roof if the unit is installed in a position where contact with
rain runoff may occur.
