When heating the pool or spa you should check the following items as they are all
critical to the proper operation of the heater.
1. WATER FLOW
Make sure all pool filters and traps are clean since the unit requires a minimum water
flow in order to operate properly. The heater should and will not run unless the water
pump is running. There is an internal water pressure switch that disables the heater
whenever the water pump is not supplying water flow.
2. WATER PUMP TIMER SETTING
Since the heat pump collects heat from the outside air, you want to set the water pump
timer to run during the hottest part of the day. If you are heating the pool from “dead
cold” you may need to set the water pump timer to run 24 hours until the pool reaches
temperature, then reset the timer for a normal run time. Run times are determined by
pool size, set pool/spa temperature and weather conditions.
3. THERMOSTAT SETTING & MODE SELECT BUTTONS
The LED display will show a constant readout of the actual cur-
rent water temperature. To set the desired water temperature
press either the + or - thermostat buttons. While adjusting the
set temperature, the LED will flash. The flashing numbers will
indicate the thermostat setting.
If you have a spa you can press the spa mode button and set the desired spa tempera-
ture. If you do not have a spa use the pool mode only.
4. OPTIONAL TIME CLOCK OVERRIDE SWITCH
The optional “Time Clock Override” control you can set the switch turn this switch ON
and the heater will start the water filter pump automatically whenever the water tem-
perature drops below the thermostat setting.
This option is best used when heating the pool from “dead cold” and
for maintaining water temperatures during non timed periods where
the pool is losing 8 to 10 degrees or more overnight. The heating
mode select switch is best left in the OFF position during the warmer
parts of the swimming season. The optional time clock override feature is built into the
heater at the factory and can not be added later. See the bottom of page 4 also.
