Maintenance

Activities required before starting maintenance
Warning of electrical voltage
Before starting any internal work on the device, switch
the main switch to position 0. For disassembly a cool-
down period of at least 30 minutes should be
observed. Before starting any internal work, check that
all motors and fans are at a standstill and that the
device has cooled down.
Activities required before starting maintenance
• For adjustment work, measurements or the like which
have to be carried out during operation, always switch over
to manual operation (ON-SITE).
• If the dehumidifier was previously operated, one is to wait
for the end of the rundown period before switching the
device off and for the end of the cool-down period of at
least 30 minutes before disassembly.
• Secure all plant sections and operating media (such as
vapour) up- and downstream the dehumidifier against
inadvertent start-up.
• For all maintenance, inspection and repair work, de-
energize the dehumidifier and secure the main switch
against inadvertent restart.
• Attach a warning sign and secure the device against
restart.
Notes on maintenance and repair activities
• Perform the stipulated adjustment, maintenance and
inspection work in due time.
• Inform the operating personnel before starting any
maintenance and repair work.
• Upon completion of the maintenance work check all
loosened screwed connections for tight fit.
• Upon completion of the maintenance work check all safety
devices for proper functioning.
Air filter change
The filter change intervals depend on the degree of air pollution
and the filter quality. Dirty filters impair the performance ability
of the dehumidifier.
A filter change is required at the latest when the filter change
indicator FILTER on the control panel lights up.

Air filters for air inlet, dry air and regeneration air
1. Open the door for accessing the air filter behind the air
inlets. In case of a standard version this means the left
door of the cabinet; if mirror-inverted, use the right door.
2. Pull the filters for the individual air inlet openings out
towards the front.
3. Change the filters as needed.
4. Then close the cabinet door again.
