ting the appliance cover").
11. Commissioning
WARNING Electrocution
Never operate the appliance when the casing is open,
without a cover or without side air connectors.

11.1 Initial start-up

Note
Fill the DHW cylinder before switching on the power
supply to the appliance. The appliance is equipped with
boil-dry protection to prevent operation with an empty
DHW cylinder.
Note
Following an interruption of the power supply, the
compressor operation remains blocked for at least one
minute. The PCB delays electronic starting by a minute,
during which the appliance goes through its initialising
process. If the compressor subsequently fails to start, it
may be locked out by additional safety devices (motor
overload relay or high pressure switch). This block should
lift after 1 to 10 minutes.

11.1.1 Fan setting subject to pressure drop
The appliance requires a constant air flow rate of 350 m³/h to op-
erate correctly. If an air duct is connected, the fan output must be
adjusted in the appliance menu due to the resulting pressure drop.
The factory setting is 40 %, intended for recirculation air mode.
