your local dealer.
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.
8 Water leak

voltage must correspond to the voltage on the identification label
of the unit.

2 turns). Refer to "[E-04] Pump only operation (air purge
function)" on page 24.
11 Shut-off valves
Make sure that the shut-off valves are correctly installed and
fully open.
Once all checks are fulfilled, the unit must be closed, only then can
the unit be powered up. When the power supply to the unit is turned
on, "88" is displayed on the remote controller during its initialization,
which might take up to 30 seconds. During this process the remote
controller can not be operated.
