SWIMMING POOL HEAT PUMP
SWIMMING POOL HEAT PUMP
Problem
Observation:
Possible cause
Solution
water leak
there's an amount of water under the heat pump
1.Condensation due to atmospheric humidity
2.Water leak
1.No action required
2.Try to localize the leak and check for the presence
of chlorine in the water. If that is the case, the heat
pump must be temporarily replaced during repair.
Problem
Observation:
Possible cause
Solution
abnormal amount of ice formed on the evaporator
the evaporator is for the most part covered in ice
1.Insufficient air inflow
2.High water temperature
3.Incorrect setting of automatic defrost control
4.The 4-way valve is out of order
5.Not enough refrigerant
1.Check the location of the heat pump and remove any
dirt that could be present on the evaporator
2.If the pool water is already quite hot (warmer than
29 (,the probability of ice formation increases.
Lowering the set temperature is a possible option
3.Check the setting of the defrosting function together
with your installer.
4.Check the voltage in the electrical wiring to the 4
-way valve. If electric potential is measured, replace
the coil. If the problem persists, have the heat pump
checked by a refrigeration technician.
5.Have the heat pump checked by a refrigeration
technician.
Problem
the heat pump doesn't work
Observation:
the screen does not light up and the fan/compressor doesn't make a sound
Possible cause
Solution
1.Wrong setting of parameters
2. Pressure switch out of order
3. Electrical failure
1.Check the set parameters and adjust them if necessary
(settings just above the capacity of the heat pump)
2. Check operation of the pressure switch by turning
off the filter pump and restarting it. If the heat pump
doesn't react to this, the pressure switch must be
adjusted or replaced.
3. Contact your installer
24
The heat pump works normally but the water is cooling down instead of heating up
The screen displays the temperature but no error codes
Problem
Observation:
Possible cause
Solution
1.The wrong mode has been selected
2. The controller is out of order
3. The 4-way valve is out of order
1.Verify the parameters, select the correct mode
2. Check the voltage in the electrical wiring to the
4-way valve. If no electric potential is measured,
replace the controller
3. Check the voltage in the electrical wiring to the
4-way valve. If electric potential is measured,
replace the coil. If the problem persists, have the
heat pump checked by a refrigeration technician
