Care and maintenance
10.1 Care and maintenance
General notes
Regular care and maintenance is fundamental
to a long service life and fault-free operation of
the unit.
All moving parts have a low-maintenance perma-
nent coat of lubricant. The refrigerant system is
designed as a hermetically sealed system and may
only be repaired by a specialist.
DANGER!
Before undertaking any work on the units, the
mains plug must be removed from the mains
socket.
n
Observe the regular care and maintenance
intervals
NOTICE!
Check the inlet and outlet grille for contamina-
tion on a regular basis.
n
In accordance with the operating conditions,
the units must be checked as and when
required, but at least once per year, by a spe-
cialist to ensure that they are in a condition that
is safe to use
n
Keep the units free of dust and other debris
n
Only clean the units with a dry or moistened
cloth
n
Never subject to direct jets of water
(
e.g. pressure washers etc.
)
n
Never use abrasive or solvent-based cleaners
n
Even with heavy contamination, use only suit-
able cleaners
Cleaning the dust filter
NOTICE!
Check the inlet and outlet grille and the dust
filter for contamination on a regular basis.
Loosen the two screws and pull out the filter frame.
Remove the filter from the frame.
Light contamination of the dust filter may be rem-
edied with careful blowing or suction.
Heavier contamination may be remedied by rinsing
the filter in a lukewarm (max. 40°C) soap solution.
Finally, always rinse the filter carefully with clear
water and allow to dry!
Before refitting the dust filter, ensure that its fully
dry and that no damage has been sustained.
NOTICE!
Heavily contaminated dust filters must be
replaced with new parts. Only original replace-
ment parts may be used.
The units may only be operated with the dust filter
in place.
