tions when assembling and operating the unit:
– Assembly, installation and servicing may only be 

performed by properly trained specialists.

– Do not obstruct the air inlet and air outlet of the 

cooling unit inside and outside the enclosure 
(see also section 4.2.2).

– The heat loss of the components installed in the 

enclosure must not exceed the specific useful 
cooling output of the cooling unit.

vertical position.

– Use only original spare parts and accessories.
– Do not make any changes to the cooling unit other 

than those described in these instructions or asso-
ciated instructions.

– Risk of burn injuries! For cooling units with auto-

matic condensate evaporation, the surface of the 
thermal element will get very hot during operation, 
and will remain so for some time afterwards.

be connected and disconnected with the system 
de-energised. Connect the pre-fuse specified on
