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 condition
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 possibil-
ity of corrosion damage to the heat exchanger. Chemical damage is not covered and
may void the warranty.
CHEMICAL FEEDERS & USAGE
1. Chemical feeders should be installed as far down-line of the heater as possible.
6" TO 8"
TO
POOL
CHLORINATOR
2. If a chemical feeder is installed at a level higher than the plumbing from the heater,
a Hartford loop must be installed that is at least as high as the top of the chemical
feeder.
3. 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 chlorine
into the heat exchanger before it is diluted with the rest of the pool water.
4. NEVER PLACE CHEMICALS IN THE POOL or SPA SKIMMER !
Chemicals placed in the skimmer will feed concentrated chemicals or chlorine into the
heat exchanger before it is diluted with the rest of the pool water. Chemicals or chlorine
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.
5. DO NOT STORE CHEMICALS NEAR THE HEATER !
6. POOL PUMP SUCTION AIR LEAKS
If a pool has a suction air leak, or the pool water level is causing the pump to suck
air into the pool plumbing, air turbulance in the heat exchanger can decrease heat
transfer and possibly cause damage to the heat exchanger.
7. PUMPS OVER 1.5 hp or 70 gpm
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.
POOL WATER BALANCE
The following standardized water
balance values should be main-
tained to reduce the risk of corrosion
and/or mineral buildup in the heat
exchanger.
