2 Safety instructions
Please observe the following general safety instruc-
tions when assembling and operating the unit:
– Assembly, installation and servicing may only be
performed by properly trained specialists.
– Screw the enclosure to the floor to prevent it from
tipping over when the cooling unit is installed.
– Do not obstruct the air inlet and air outlet of the
cooling unit inside and outside the enclosure
(see also section 4.2.2).
– To ensure problem-free opening and closing of
the enclosure door, use a ride-up door roller (refer
to the accessories in the RITTAL Catalogue).
This raises the door slightly and balances out the
weight of the cooling unit, to prevent buckling of
the door and associated seal problems.
– The heat loss of the components installed in the
enclosure must not exceed the specific useful
cooling output of the cooling unit.
– When transporting the enclosure with the cooling
unit externally mounted, always use an additional
shipping brace to support the cooling unit.
– The cooling unit must always be transported in an
upright 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.
– The mains connector of the cooling unit must only
be connected and disconnected with the system
de-energised. Connect the pre-fuse specified on
the rating plate.
