CHEMICAL USE
Water quality must be checked regularly and maintained within recommended limits at all times.
Failure to maintain the proper water quality will greatly reduce the life of your heater.
•
Never add chemicals directly into skimmer.
•
Automatic chlorinators must be piped downstream from the heater. A check valve must be installed
between the chlorinator and heater to prevent raw chlorine from draining back into the heater. A chemical
trap may be piped at least six (6) inches above the chlorinator. See piping diagram B.
Always maintain the following water quality requirements:
PH LEVEL 7.4 to 7.8
CHLORINE CONCENTRATION 1 to 5 PPM
TOTAL ALKALINITY 100 to 200 PPM
CALCIUM HARDNESS 100 to 300 PPM
