This heat pump is equipped with the highest marine grade cupronickel alloy heat ex-
changer that is designed to resist corrosion from normal pool water. The life and con-
dition of the heat exchanger is directly related to the pool water chemical balance and
chemical usage techniques. The following precautions are required to help prevent
the possibility of corrosion damage to the heat exchanger. Chemical damage is not
covered and may void the warranty.
CHEMICAL FEEDERS & USAGE
1. All Chemical feeders must be installed as far "down-line" of the heater as possible.
2. A check valve and chemical trap loop must be installed between the heater and any
chemical feeders as shown here (and in the installation manual). The loop will help
prevent chemical backup into the heater.
3. All feeders should be installed at the same or below the heater piping elevation to
prevent chemical back up into the heater.
4. Do not install a chemical feeder on the suction side of the filter system. Feeders and
chlorinators installed on the suction side will discharge concentrated chemical or chlo-
rine into the heat exchanger before it is diluted with the rest of the pool water.
5. NEVER PLACE CHEMICALS IN THE POOL or SPA SKIMMER !
Chemicals placed in the skimmer will feed concentrated chemical or chlorine into the
heat exchanger before it is diluted with the rest of the pool water. Chemicals or chlo-
rine placed in the skimmer will dissolve and concentrate in the skimmer when the
water pump is off and then send a super concentrated chemical solution through the
heater every time the water pump restarts.
6. DO NOT STORE CHEMICALS NEAR THE HEATER !
POOL WATER BALANCE
The following standardized water balance
values should be maintained to reduce the
risk of corrosion and/or mineral buildup
in the heat exchanger.
POOL WATER PUMP REQUIREMENTS
The water pump creates a vacuum on the skimmer line and the bottom floor suction
drain in the pool. If there is an imperfection in the filter system or plumbing, the pump
will draw air into the piping. This air will cause turbulence in the heat exchanger de-
creasing heat transfer and possibly causing physical erosion.
NOTE: Be advised that water pumps rated over 1.5 H.P. or over 70 gallons per
minute must have a plumbing bypass added to the exterior heater piping as
shown in the technicians installation manual. Be aware of this when upgrading
your existing water pump.
MINIMUM WATER BALANCE REQUIREMENTS
pH - 7.4 to 7.6
Chlorine - 1.0 to 5.0 p.p.m.
Alkalinity - 90 to 120 p.p.m.
Calcium - 200 to 350 p.p.m.
