Note-Five (5) Minute Time Delay Function:

The heater controls contain a solid-state time delay module. This time delay feature prevents damage to the compressor should electrical power be repeatedly interrupted, or if the heat pump were to come under any other circumstances leading to an on-off-on-off cycling condi- tion. If the heater has water flow and electrical power supplied, but the heater does not imme- diately start upon turning the thermostat to its highest setting, wait five (5) minutes; the time delay module may be preventing the heater from operating. Likewise, once the heater is running, if the thermostat is turned back below the present water temperature, the heat pump will shut off. Subsequently, the heater cannot restart for approximately five (5) minutes, no matter how far the thermostat is turned back up.

4. Ensure Uninterrupted Pump Operation During Initial Warm-Up:

uPermit your pool or spa circulation pump to run continuously until the desired water temperature is reached. (with a pool, this may take several days.)

uContinuous pump operation will likely require temporarily resetting (or removing completely) the trippers on the time clock, thus allowing nonstop operation. When an external electronic controller operates pumps and valves, follow the controller manufacturer's instructions to ensure temporary, uninterrupted pump operation.

uThroughout the warm-up period, keep the selected pool or spa thermostat dial set clockwise to its highest setting.

5.Desired Water Temp. Reached-Set Thermostat to Maintain:

uOnce the desired water temperature has been achieved, rotate the thermostat knob very slowly counterclockwise until the unit (just) shuts off.

uThe heater will automatically maintain your pool or spa at the selected temperature.

6.Return Pump Timer Controls to Normal Settings:

uReset pump timer controls for normal daily hours of operation.

uDuring cooler or cold weather conditions, it may become necessary to extend the daily hours of pump operation; doing so will help the heater to keep up with increased heat losses.

Heating Tips

Pool/Spa Blankets

A solar blanket will significantly reduce your heating bills. You should check with the installing dealer to see if your heat pump was sized to be used in conjunction with a solar blanket or without one. Blanketed pools will typically lose only 3 - 4° of heat per night versus 8 - 10° overnight with an un-blanketed pool. Reductions of 40 - 60% on heating bills can be achieved by using solar blankets.

WARNING ! Failure to heed the following may result in permanent injury or death.

Improperly used, Pool-Spa solar blankets can become a drowning risk to people and pets. Solar blankets are not safety covers. They are not designed to support the weight of a person or pet. Never enter a pool until the solar cover is completely removed (under no circumstances should anyone swim under the blanket). Follow all safety recommendations of the blanket manufacturer.
