COLD WEATHER OPERATION

IMPORTANT FREEZE INFORMATION

MODERATE CLIMATE: Heater operation can contin- ue during short-term cold spells. When temperatures are between 0° and 32°F, flow (continuous pump operation) must be maintained.

CAUTION: Do not use the heater to maintain water temperatures just above freezing or for freeze protec- tion. When heater is used during freezing weather, care must be taken to avoid freeze-ups. Continuous pump operation is a must. Additional protection may be required. The heater is not warranted against freeze-ups.

COLD CLIMATE: Prolonged operation with water temperatures below 50°F is not recommended. When starting the heater with water temperatures below 50°F, operate the heater continuously until higher temperatures are reached. Operating the heater for prolonged periods with pool water below 50°F can seriously damage the heater, and is not cov- ered by the warranty.

For cold climate areas, please follow the winterizing procedures listed.

WINTERIZING THE POOL & SPA HEATER

Heaters installed outdoors in freezing climate areas may be shut down for the winter. Observe the follow- ing procedure for winterizing the heater:

1.Turn off gas valve, manual gas valve, and electri- cal supply to the heater.

2.Open drain plug located on the inlet/outlet header, (under water pipes). Remove the heat exchanger inspection panel on the side opposite water piping to gain access to the drain plug on the return head- er. Open drain plug on return header.

3.For ASME Heaters only: Disconnect compression fittings from the pressure switch and return header that connects to the 1/4" copper tube and allow the tube to drain.
