are to be checked for tightness at least once are year. All seals have to be inspected at least one a year.
7.3.4 Checking the compressor
Mandatory annual control must be done by trained service personnel. The service issued by the pump
manufacturer must be followed. The pressure expansion system must be checked once a year. If
necessary, the pressure must be increased to the correct level.
7.3.4.1 Inspection
Suggestion for checks may include:
• Any abnormal noises from the compressor;
• Oil leaks from pipes or compressor;
• Any corrosion on soldering or pipes;
• Any refilling with refrigerant R410A;
• Visual checks in sight glass.
7.3.5 Checking the evaporator coil
The evaporator coil is used to absorb heat from extracted air. The coil will have reduced capacity if dust
forms a coating on the coil surface and increases the pressure drop on the air side. Even if the Living HP
is fitted with the extract air filters, dust eventually will deposit on the coil fins.
