Raypak 302-902 Automatic Chlorinators And Chemicalfeeders, Winterizingyour Heater, Fig. #9225

AUTOMATIC CHLORINATORS AND CHEMICALFEEDERS

All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater. Do not place chlorine tablets or bromine sticks in the skimmer. High chemical concentrations will result when the pump is not running (i.e. overnight).

Chlorinators must feed downstream of the heater and have an anti-siphoning device to prevent chemical backup into the heater when the pump is shut off.

NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause very rapid corrosion to the heat exchanger in the heater. Such damage is not covered under the warranty.

WINTERIZINGYOUR HEATER

When heaters installed outdoors in freezing climate areas are to be shut down for the winter, please observe the following step-by-step procedure:

1.Turn off manual main gas and main gas shut off. Remove the drain plug or open the drain cock located on the bottom header.

SPAWATER CHEMISTRY

NOTE: Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water pH between 7.4 and 7.8 and total alkalinity between 100 and 150 p.p.m. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and also damaging the heater. If the pH drops below 7.2, the heater will be severely damaged.

NOTE: Heat exchanger damage resulting from chemical imbalance is not covered under the warranty.
