– Before performing any maintenance or repair work, switch o the main power panel switch, remove the
fuses (or switch o the circuit breakers) or open the unit's protection devices.
– Before starting any maintenance or repair work, make sure that the unit is switched o.
– After disconnecting the power supply, wait 10 minutes before touching live parts to avoid risks due to
residual voltages in the DC bus condensers of the compressor inverter.
– Note that some sections of the electrical box are very hot. The same applies to the components of the
high pressure refrigeration circuit. Consider the risk of burns and wear personal protective equipment
before carrying out any work in these areas.
– Do not touch the conductive sections.
– Do not rinse the unit. Humidity can cause an electric shock or a fire risk.
– When removing the service panels, there is a risk of accidentally touching live components.
– When installing or servicing, never leave the unit unattended after removing the service panels.
The checks described should be carried out at least once a year by a qualified technician.

storage tank, remove the booster heater from the storage tank and immerse
it in a bucket (or other container) with limescale removal product for 24 hours.
Unit control box
