Cleaning internal components
For cleaning the interior of the unit
and to gain access to the electri-
cal components, it is necessary to
open the unit housing.
■
Clean the components either by
blowing out, suction, inlet grille
or with a soft brush. Do not use
a jet of water!
■
Carefully clean the internal
surfaces of the unit, condensate
trap with hose connection, fan
and fan housing.
■
Check all unit components for
possible damage and repair if
necessary.
■
Carefully refit all previously
removed components in the
reverse order.
NOTE
Only authorised specialists
may carry out adjustments and
maintenance.
Troubleshooting
The units were manufactured us-
ing the latest production methods
and tested repeatedly for perfect
function.
If faults should still occur, the unit
must be checked against the fol-
lowing list.
The unit does not start:
■
Check unit installation (tilt
switch)
The unit will only operate in an
upright position!
■
Check the supply connection
and system fuse
230V/1~/50
Hz
on-site
■
Check the mains plug and
power cord for damage
■
Check the condensate container
for level and correct seating
The “FULL TANK” indicator
light must not light up!
■
Check the microswitch of the
condensate container
■
Check for free air flow
Overheating
!
■
Check the miniature fuse on the
control pcb
The unit operates, but with
no condensate formation:
■
Check the room temperature
The operating range of the unit
is between 1°C and 40°C
■
Humidity has not reached
the fixed value (45% relative
humidity)
■
Check the air inlet and outlet
grilles for fouling
Clean or replace if necessary!
■
Have the exchanger surface of
the absorption rotor checked
for fouling.
This work makes it necessary
to open the unit and must
be carried out only by an
authorised specialist!
The unit is loud or
condensate discharges:
■
Check that the unit is standing
on a level and firm surface.
■
Check that the unit is standing
upright and stable.
■
Have the condensate trap or
connection checked for dirt
deposits.
This work makes it necessary
to open the unit and must
be carried out only by an
authorised specialist!
NOTE
Only authorised specialists
may carry out adjustments and
maintenance.
NOTE
Particular care must be taken
when cleaning the adsorption
rotor as the surface must not
be subjected to any mechani-
cal load.
ATTENTION
After carrying out all work on
the units, an electrical safety
test must be carried out in ac-
cordance with VDE 0701.
