CHLORINATOR PLACEMENT
1. All chlorinators should have a chemical resistant
check valve and a loop plumbed at least 8 inches above
the chlorinator, between it and the heater, as far down
line from the heater as possible.
2. Never plumb a chlorinator into the suction side of
the circulation pump. All automatic chemical feeders
should be as far down line of the heaters water flow as
possible.
3. Off line type chlorinators should be tapped into the
plumbing only as shown on the diagram. See pool/spa
combinations requiring special placement. See plumb-
ing diagram.
4. Never install a chlorinator at a higher elevation than
the lowest heater piping even if a loop check valve is
used. Doing so may allow chlorine to migrate to the
heat exchanger, causing damage.
5. Do not allow floating chlorinators to be drawn up to
the skimmer inlet.
6. Keep the chlorinator lid o-ring lubricated with sili-
cone grease. Replace when needed.

Do not place any chemicals in the skimmer throat.
Chlorine tablets placed in the skimmer will allow a
concentrated solution of chlorine to pass through the
heat exchanger causing damage.
7. Do not place any chemicals in the pump lint trap cav-
ity or filter. Make sure the lint trap basket is placed
properly to prevent debris from clogging the heat ex-
changer.
8. Do not over load chlorinator feeder cavity. Exces-
sive amounts of chlorine tablets will increase the chance
of migration of acetic, concentrated chlorine to migrate
to the heat exchanger causing damage. 25% of maxi-
mum is suggested.
9. When adding gas chlorine make sure that the pH does
not drop below 7.4. Make sure that the total alkalinity
does not drop below 90 p.p.m. Gas chlorine is very ace-
tic.
10. Do not isolate the heater from the water flow unless
you have installed a drain plug to drain all the water
from the heat exchanger and then blow out with pres-
surized air. Stagnant water will corrode the heat ex-
changer and piping.
