3. Insufficient refrigerant.
Check that there are no leaks in the appliance and
system, if necessary repair them. Replace the refrigerant
with new product and correct quantity.
4. Temperature out of range
Check that the setpoint temperature is not too high in
heating or too low in cooling.
Abnormal noise from the pump or no
water circulation while the pump is
running
1. Water loss in the circuit.
Check the filling tap, fill the circuit with the right amount
of water.

Remove air from the circuit.
3. The valves in the hydraulic circuit are
not fully open.
Verify that all valves are fully open.
4. The water filter is dirty or clogged.
Clean the filter or replace it.
Compressor discharge pressure too
high
1. Too much refrigerant.
Replace the refrigerant with new product and correct
quantity.
2. Air in the refrigerant circuit.
Replace the refrigerant with new product and correct
quantity.
3. Inadequate water flow.
Check the water flow in the circuit, if necessary use a
more performing pump.
4. Too high temperature.
Make sure that the water supply temperature sensor
works properly.
Suction pressure too low
1. Dirty filter drier.
Replace the filter drier.
2. Electronic expansion valve blocked.
Repair or replace it.
