2. INTRODUCTION

A WARNING: This
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 swimming 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.
As with all heaters, compared to other types of heaters
such as gas or oil-fired, this heater has lower heating
capacity on a BTUH/hr basis. As a result, it will be required
to operate longer to accomplish the desired results. It
may, at certain times, operate as much as 24 hours per
day. However, this should not be of concern to the owner,
because the unit is designed to operate continuously.
Even though it may operate continuously for many hours,
it will still heat the pool with greater economy than heaters
driven by fossil fuel.
Place a cover or blanket over the pool at night and other
non-use periods. This will keep evaporation, the cause of
main heat loss, to a minimum, and will greatly reduce pool
heating costs. During warmer weather, the cover may be
required only at night.

Water Chemistry

A WARNING: Do not install the unit within 3 ft (91 cm)
of fossil-fuel-burning heaters. Air intake along the sides
of this heater could disturb the combustion process of
an
the unit, and could cause damage or personal injury.
a
• Mount the unit on a level, sturdy base, preferably a
concrete slab or blocks. The size of the base should
be at least 3 ft by 3 ft (91 cm by 91 cm).
• You must install the 4 black rubber sound isolation
pads (each 2 inches square [5.1² cm]) that ship with
the unit. The pads are shipped in a bag with the
unions, gaskets and the I&O manual. Install pads
under the 4 corners of the unit to reduce vibration
and sound transmission to the base.
CAUTION: The unit's supporting base must be high
enough to keep it completely free of standing water at
all times.
Situate 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 at least 1 ft (30.5 cm)
from walls, pipes and other obstructions.
WARNING: This unit is designed for outdoor
A
installation ONLY; DO NOT install it in an enclosed area
such as a shed or garage.
4. WATER CHEMISTRY
NOTE:
Damaged caused by water chemistry outside
these guidelines will not be covered under warranty.
For your health and the protection of your pool equipment,
it is essential that your water be chemically balanced.
Damage to the unit caused by improper water chemistry
will not be covered under warranty. Accordingly, use the
levels in Table A as a guide for balanced water.
• Occasional chemical shock dosing of the pool or spa
water should not damage the heater providing the
water is balanced.
