Recommendations

Any intervention of the refrigerating circuit should be done profession-
ally following the safety regulations in force in the profession: retrieval
of freezing agent fluid, brazing under nitrogen, etc...
Any brazing intervention should be done by professional qualified re-
frigeration engineers.
This device has equipment under pressure, the refrigerating pipes.
Only use the original parts for replacing faulty refrigerating components.
Replacement of pipes may only be done with copper tube comply-
ing with standard NF EN 12735-1.
Any replacement with a part which is not an original one, any modi-
fications of the refrigerating circuit, any replacement of the freezing
agent fluid by a different fluid from that indicated on the identification
plate, any use of the device outside of the application limits appear-
ing in the documentation, will result in cancellation of the warranty as
well as the EC labelling complying with the Equipment under Pressure
Directive (if necessary) which will become the responsibility of the per-
son who carried out these modifications.

Maintenance

Dirt may accumulate in the evaporator. You can easily dislodge it with the
help of a jet of water without damaging the aluminium fins.
You can clean the plastic parts using a brush and all-purpose soap.

Wintering

Put the heat pump in OFF mode, to do so set the pre-defined temperature to the
minimum then cut the electrical supply of the heat pump.
At the end of the heating season it is essential to drain the condenser in order
to avoid the water turning to ice by the extreme temperatures which would
risk causing irreversible damage. To do this, close the water entry and exit
valve then disconnect the pipe to let the water in the condenser drain freely.
You could even use a jet of compressed air to eliminate any stagnant water
in the condenser. With the water entry and exit stop valves closed and the
pipe drained you can reconnect the pipe.
It is recommended that you cover the heat pump with its wintering cover in
order into protect it against bad weather and the rigours of winter.
