10 Problems / solutions :
The difficulties met the most often can be solved by reading the table below.
If nothing corresponds to the list, or if the solutions applied do not solve the problem, refer to the notice or contact your retailer.
Problem Observation Probable cause Explanation/Solution
The heat pump does
not start
Screen extinct No electric food Check the connection with the
catch or / and the interlocking of the
circuit breaker at the head of line
The heat pump does
not start
Screen on Voltage to low Find out the reason and repair
The heat pump starts and
stops within a
few minutes
Find out the reason and repair
Compressor failure
Refrigerant circuit is damped
Four way valve failure
Check leakage, charge
refrigerant
with right amount
Change compressor
Find the damp reason and make some
changes
Change
The temperature of
the water increases
very
slowly
The heat pump works Water temperature and
ambient temperature too low
Water amount used continuously
too
large.
Water is running
under the heat pump
Water comes from the low vat
The black, plastic conduit
to evacuate the
condensates is not
connected or is stopped
The condensates are entailed by
the
condensation of the humid air
on the wings of the
evaporator. It’s quite natural.
Install the conduit or destop it.
Some frost appears
outside, on the wings
of the evaporator
The thickness of the frost is thin Ambient temperature is
too low
The frost is entailed by the freezing of
the humid air on the wings
of the
evaporator. It’s quite natural and
the heat pump is going
to defrost. Consider the
wintering of the heat pump. The thickness of the
frost is thick (the
blades of the
ventilator may rub on
the ice
much more thicker inside)
The deicing probe
or the thermic circuit
breaker does not work
Stop the heat pump and
call your retailer
The heat pump works but
the temperature of
the water does not rise (*)
The pressure of the
refrigerant
shown on the
manometer is very low
Escape of the refrigerant
Stop the heat pump and
call your retailer or a refrigeration
technician
The pressure of the
manometer is right
Breakdown or abnormal
wear of the compressor
The heat pump
emits noises of
vibration or sheet
The sheets of the casing do not
seem to be shocked
The screws are enlightened
Tighten the screws of the carter or call
your retailer
