CHAUFFAGE FRANCAIS Stelios 250 L Benutzerhandbuch Seite 64

Failure Description
The device no longer
works.
Low performance in
sanitary production.
The compressor is not
working.
The Compressor
noisy.
The fan does not work
The device does not
produce heat while the
compressor is working
The discharge pressure
is too high.
The suction pressure is
too low.
1) Water flows from the drain port of the safety valve:
When producing hot water, the cold water contained in the device is heated and
expands, so that water flows from the drain port of the safety valve, which is normal.
However, if the water flows continuously, it means that the safety valve loses its
Non-Unit effectiveness. You must stop using the device and replace the safety valve as soon as
Fail possible.
2) The heating time of the water of an entire tank becomes longer:
When the temperature is low enough in winter (e.g. 0℃), the performance of the
heat pump to produce hot water will not be as good as usual, so the water heating time of
an entire tank becomes longer.
ATTENTION
If the device remains defective despite all these checks, you must contact your installer or technical
station as soon as possible.
Table 2 Common Failures
Reason

Compressor remains interrupted.
2. The compressor
contactor is defective.
3. Poor electrical connections.
4. Compressor
protection tripped.
There are defective internal
is
components
2. Insufficient oil level.
1. The condenser is out of order.
2. The motor is out of order.
1. More Refrigerant (Leak).
2. The compressor is out of order.
1. Too much refrigerant.
2. Non-condensable product in
the refrigerating installation.
1. The filter is clogged.
