Cleaning the units
The unit housing must be opened
to allow the inside of the unit to be
cleaned and to provide access to
electrical components.
1. Remove the power plug from
the mains socket.
2. Disassemble the transportation
bracket (A) and the stand (B) by
removing the 4 threaded screws.
3. Dismantle both side covering
panels (C).
To do this, loosen each
self-tapping screw from
the underside, slide the sheet
downwards towards the wheel
and then upwards out of
the holder.
Remove the earth conductor
on the inside of the panel.
Cleaning the dust filter
Slide the protection grid upwards
slightly, then pull forwards and
remove downwards.
Then remove the dust filter which
has now been released.
Light contamination of the dust
filter may be remedied 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.
The units may only be operated
with the dust filter in place.
■
Observe the regular care and
maintenance intervals
■
In accordance with
the operating conditions,
the units must, if necessary,
be checked at least yearly by a
specialist to ensure that they are
in a condition that is safe to use
■
Keep the units free of dust and
other debris
■
Only clean the units with a dry
or moistened cloth
■
Never subject to direct jets of water
e.g. pressure washers etc.
■
Never use abrasive or solvent-
based cleaners
■
Use only suitable cleaners, even
for heavy contamination
Care and maintenance
All moving parts have a low-
maintenance permanent coat of
lubricant. The refrigerant system is
designed as a hermetically sealed
system and may only be repaired
by a specialist.
NOTE
Regular care and maintenance
is fundamental to a long
service life and fault-free
operation of the unit.
CAUTION
Before undertaking any work
on the units, the power
plug must be removed from
the mains socket.
NOTE
Heavily contaminated dust
filters must be replaced with
new parts.
Only original spare parts may
be used.
CAUTION
Check the inlet and outlet
grille and the dust filter for
contamination on a regular basis.
NOTE
Adjustment and maintenance
work may only be carried out
by authorised and qualified
technicians.
