CHLORINATOR
The chemical resistant check valve and loop MUST
be installed with all types of chlorinators to pre-
vent chlorine migration to the heater. The loop
should extend at least 8 inches above the chlorinator
top. The chemical resistant check valve should be
placed on the pipe leading "up" to the chlorinator.
Therefore, the weight of the water above the check
valve will hold it closed even if the spring is weak or
damaged. Mount the check valve as low as possible.
Be sure to keep the chlorinator, pump and filter lid o-
rings lubricated with silicone grease to insure a good
seal. If it looses its seal, it will allow the chlorine to
migrate to the heater when the system shuts off. The
loss of vacuum will allow reverse flow.

CAUTION
CAUTION
Air leaks or suction leaks that allow air into the system will
cause turbulence and damage to the sacrificial fittings. Cor-
rect immediately ! Do not add isolation valves unless required
for seasonal shut down & freeze protection procedures. Stag-
nant water left in the heat exchanger can cause corrosion !
