2. WATER CHEMISTRY
(Corrosive water voids all warranties)
For your health and the protection of your pool equipment,
it is essential that your water be chemically balanced. The
following levels, see Table A, must be used 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.
Recommended Level(s)
Water Temp. (Deg. F)
pH
Total Alkalinity (PPM)
Calcium Hardness (PPM)
Salt (PPM)
Free Chlorine (PPM)*
Total Dissolved Solids (PPM)
*Free Chlorine MUST NOT EXCEED 5 PPM!
** In salt water chlorinated pools, the total TDS can be as high as 6000ppm
3. INTRODUCTION
WARNING: This heater is an electromechanical
A
machine that incorporates a 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 heating swimming pools. 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.
Since evaporation is the main cause of heat loss from a
pool, keeping the pool covered whenever it is not in use will

Further advice should be obtained from your pool
or spa builder, accredited pool shop, or chemical
supplier for the correct levels for your water.

CONSIDERATIONS
WARNING: Do not install the unit within 3 ft (91
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
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.
