4. Ensure Uninterrupted Pump Operation During Initial Warm-Up:
u Permit your pool or spa circulation pump to run continuously until the desired water temperature is
reached. (with a pool, this may take several days.)
u Continuous 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.
u Throughout 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:
u Once the desired water temperature has been achieved, rotate the thermostat knob very slowly
counterclockwise until the unit (just) shuts off.
u The heater will automatically maintain your pool or spa at the selected temperature.
6. Return Pump Timer Controls to Normal Settings:
u Reset pump timer controls for normal daily hours of operation.
u During 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.

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.

Heating Tips
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
.
Pool/Spa Blankets
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.
Failure to heed the following may result in permanent injury or
death.
