Problem Possible Cause Possible Solution(s)
Unit is not operating
No power to unit Make sure power is on
Breaker is tripped Check the breaker / see note above
Thermostat too low Turn thermostat up until unit comes on
3 minute compressor delay timer still running Be sure the delay has passed
Low water flow
Make sure filter is clean
Make sure filter pump is on
Unhook cleaning devices
Outside temperature too low
Check outside ambient temperature or wait for warmer tempera-
tures to operate (Refer to Operating section)
Fan not functioning Call for service
Heat pump is running but
Display LEDs not on
System Component Failure Call for service
Heat pump runs continually
Thermostat set too high for ambient
temperature
Turn thermostat down
Evaporator is dirty
Clean by running tap water over the coil without additional nozzle
attachment. Do not use pressurized water as it can damage the coil
and void warranty.
Electrical component failure
Turn off pump. If the unit is still running after 3 minutes, turn off the
power to the unit and call for service.
Heat pump is cycling
(on / off too quickly)
Bad bypass valve or improper water flow
Ensure water flow is sufficient (is the filter pump running
continually?) If heat pump continues to cycle, turn unit off to pre-
vent compressor damage.
Low refrigerant, low abient temperature, or
high humidity with low ambient temperature
Check evaporator coil for severe frost. Turn unit off to prevent
compressor damage.
If heat pump continues to cycle, turn unit off to prevent compressor
damage. Call for service.
Water is coming from
bottom of unit
Condensation This is normal and there is no reason to be concerned
Possible water leak
Turn the unit off for several hours, but leave the filter pump running
continuously. If water quantity decreases, then it is only
condensation. Otherwise there is a possible leak.
