MAINTENANCE
– Prior to undertaking any maintenance operation on the HP, it is imperative to disconnect the power supply from the HP: there is a risk of electrocution that
can cause damages, severe injuries, and even death. Maintenance operations are to be conducted by a qualified technician.
Cleaning (must be conducted by a qualified technician at least once yearly):
– The cleaning of the inlet of the evaporators and of the outlet of the fan are necessary to maintain a sufficient yield.
– The HP outer casing must be cleaned with a damp soft cloth (microfibre for example). The use of detergent and other household products might damage the
surface of the casing and change its properties.
– The evaporator, at the rear of the HP, can be cleaned carefully using a soft brush vacuum cleaner, just a soft brush, or a stream of soft water; never use a
high-pressure hose.
Yearly maintenance, safety checks (must be conducted by a qualified technician at least once yearly):
Prior to any maintenance operation, it is imperative to power down the device and to wait a few minutes before installing pressure control devices, as the
high pressure and temperature in some parts of the cooling circuit could cause severe burns.
– Check that the electric cables are properly connected.
– Check that the earth terminals are properly connected to the earth.
– Check the state of the pressure gauge, and that the pressure is aligned with the temperature (table below), and for the presence of coolant.
