SPRING AND FALL OPERATION

If the pool is being used occasionally, do not turn the heater completely off. Set the thermostat down to 65° F. This will keep the pool and the surrounding ground warm enough to bring the pool up to a comfortable swimming temperature in a shorter period of time.

WINTER OPERATION

CAUTION

•Operating this heater continuously at water temperatures below 68° F. will cause harmful condensation and will damage the heater and void the warranty.

•If the heater has been drained for freezing condition, do NOT turn "ON" until the system is circulating water.

•Water trapped in the heat exchanger can result in freeze damage to the exchanger or headers. Freeze damage is specifically not covered by the warranty.

If the pool won't be used for a month or more, turn the heater off at the main gas valve. For areas where there is no danger of water freezing, water should circulate through the heater all year long, even though you are not heating your swimming pool. The MiniMax NT should not be operated outdoors at temperatures below 0° F. for propane and -20° F. for natural gas. Where freezing is possible, it is necessary to drain the water from the heater. This may be done by opening the drain valve, located at the inlet/outlet header, (see Figure 29.), allowing all water to drain out of the heater. It would be a good practice to use compressed air to blow the water out of the heat exchanger. (See additional notes under Important Notices in

Introduction.)
