5. TIME DELAY MODE

This heater is equipped with an internal compressor time delay to allow the refrigerant to

settle during start-up or restart cycles. When the heater is started the fan will run but the

compressor will not start until the 3 to 5 minute delay has passed. The green heating light

will be on when the compressor is running. In some cases (when the heater is new or

during cold weather), it may be necessary to allow the unit to go through the time delay

several times before the unit will start. The unit will delay for other reasons noted below:

TIME DELAYS:

30 second compressor delay when switching pool/spa modes.

3 to 5 minute compressor delay when T.C.O. enables in pool mode.

5 minute T.C.O. off delay when: switching from spa to pool mode, when temperature is

reached in pool mode, or if LF (low water ﬂow) is displayed on LED.

If water pump loses prime there will be a 3-5 minute compressor delay.

6. NORMAL OPERATION INDICATORS

When the fan and compressor are running, the unit will discharge cool air from the top.

The heater will produce condensation while running and is considered normal. It will

produce more condensation the more humid the ambient air is. The condensation will

exit the heater through the bottom drain ports.

7. POOL/SPA COVER USE

You can substantially reduce the heat loss and electrical consumption by utilizing a pool

cover or pool blanket. You can get higher water temperatures in less operational time

using a cover. If you keep the pool or spa covered whenever you are not swimming you

can typically reduce heat loss by as much as 80% and reduce heating costs as much as

50%. Using a cover during the initial heat up period will greatly reduce the operational

time needed.

8. SPA HEATING

When heating a spa it is advisable to not run the air blower or air inlet venturis during the

initial heat up time. Air blowers and venturis inject air into the water to create the spa

therapy action. During colder weather the air blower or inlet venturis will inject cold air

into the spa thus increasing heat demand. Leaving these items off until the spa reaches

the set temperature will reduce the heat up time. A cover is highly suggested for spa

heating.

9. DEFROST CONTROL IN COLD WEATHER

DF This readout indicates that the internal defrost safety control has disabled the heater.

During cold weather where the air temperature drops below approximately 45 to 50 de-

grees (depending on humidity), the low refrigerant pressure switch (or defrost control) is

designed to disable the compressor only. Once the unit is in defrost mode the compres-

sor will shut off for 1 hour while the fan continues to help deice and warm the air coil.

After 1 hour the unit will attempt to restart. If the air temperature has increased to the

operational range the compressor will continue to run, otherwise the compressor will return

to the defrost mode for another 1 hour delay cycle.

You my experience some frost or icing on the outer air coil in cold weather temperatures

and is considered normal. If the air coil ices up, shut the heater off, allow it to defrost and

wait for warmer weather to restart the heater. If you live in an area where the weather

is expected to drop below 45˚F to 50˚F for an extended period you should disable the

heater during those times.
