!
Please note
Commissioning is weather-

In the event of high relative
humidity (e.g. in the case of
heavy rain or fog) or outside tem-
peratures below –5 °C, the sys-
tem

be evacuated prop-
erly.
Danger
Direct contact with refrigerant

Please note
Before evacuating the refrigerant
lines and the internal unit, check
all connections for tightness with
leak detecting spray:
Keep the valves on the external

nitrogen through the service
valve. The test pressure is the
max. permissible operating pres-
