Operational Instructions

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 un-

less 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 current 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

temperature. 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 temperature drops below the

thermostat setting.

This option is best used when heating the pool from "dead cold" and for main-

taining 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
