Commissioning
11. Commissioning
!
Material losses
To prevent the temperature falling below the dew point,
the casing must be closed during operation and undam-
aged.
A contractor must commission the appliance, make all the set-
tings at the commissioning level of the heat pump manager, and
instruct the user.
Commissioning must be carried out in accordance with these op-
erating and installation instructions and the operating and instal-
lation instructions of all components belonging to the heat pump
system. Our customer support can assist with commissioning,
which is a chargeable service.
A heat pump system can comprise many different components.
A sound knowledge of the system function is therefore essential.
Where this appliance is intended for commercial use, the rules of
the relevant Health & Safety at Work Act may be applied during
commissioning. For further details, check with your local super-
visory body; in Germany for example, this is theTÜV.
