operation. After the desired temperature is reached, return the system to normal operation.

•Is airflow through the unit being obstructed? Restrictions such as shrubbery, tall grass, dirty coils, or any other obstruction to airflow will reduce performance.

•Is the pool blanket/cover being used? Unblanketed pools can lose up to 6° per night compared to 2 degrees or less when a blanket is used. Without a blanket, the total heat gained during the day can be lost overnight.

•Are rapid heat losses occurring in some other way, such as high wind, waterfalls, spa spillage, bubblers, rainfall, flow through solar panels at nights, or a high water table?

•Is water flow through the unit adequate? Check the system for obstructions, such as a clogged filter pump strainer or a dirty filter.

B.UNIT IS NOT RUNNING

•Is the control panel Power lamp ON? If not, the power switch may be shut OFF or circuit breaker tripped. Reset the power by switching it OFF, then back ON.

Verify that the circuit breaker is set and operating properly before calling for service.

•Is the thermostat setting correct? Verify that the temperature has been properly set on the thermostat, and that it is higher than the current water temperature.

•Have you waited 6 minutes for the time delay? After the unit has been running and then shut OFF for any reason, there is a 6-minutes timed cycle before operation can begin again.

•Is the Water Flow lamp OFF? This lamp will turn OFF if not enough water is flowing through the heater. Improperly positioned valves or a dirty filter could decrease the flow of water required for efficient operation. When the Water Flow lamp is ON, proper flow is present. If this lamp is OFF, but you can feel normal flow at the pool returns, check the water valves or settings.

•Is the Defrost Active lamp OFF? If this lamp is ON, the fan will be running but not the compressor. The unit is waiting for the frost to melt or the air temperature to rise before heating is resumed.

•Is the Heat Demand lamp ON? If not, then the thermostat setting is not higher than the temperature of the pool water. Raise the thermostat setting.

•Is the Low Pressure lamp ON? If this lamp is ON, there is a problem with the unit that will require service. Turn the unit OFF and call the number shown in the CONTACT INFORMATION at the beginning of this manual.
