Maintenance
Safety
CAUTION!
The installation, adjustment, maintenance and any repairs must be carried out
by qualified personnel informed of the risks related to the operations of equipment supplied
from high voltage and high temperature.
CAUTION!
The power supply is constantly present in the switch for the unit. Risk of electric
shock.
CAUTION!
After a power failure the dehumidifier may restart automatically. Turn off the
main switch and always padlocked supply before performing any maintenance work
.
PLEASE NOTE! For any maintenance or repair:
Wait 15 minutes after turning off the dryer before opening any service panel, in order to
allow for the cooling of the reactivation coil.
Electrically disconnect the dehumidifier via the main switch
.
Disconnect the power plug
The maintenance intervals depend on the environment which the dehumidifier is installed in. The
frequency of these intervals may differ from one installation to another. Improper maintenance can
result in decreased performance.
Filters
The dehumidifier is equipped with two separate filters, one for the process air and one for the
reactivation air. The filters are placed on the inputs airflows of the dehumidifier. Cleaning or filter
replacement intervals will be determined by the amount of dust and air particles where you installed the
dehumidifier.
The filters should be checked at least once a month.
The unit can be equipped with the differential pressure gauges to check the pressure drop through the
filters. Do not leave the dehumidifier in operation without the filters: the rotor could be ruined.
Rotor
The rotor doesn’t need maintenance. However you may need to clean it very delicately with compressed
air. If it is very dirty, the rotor can be washed with water but before you do this, contact your local
distributor because it is not a routine operation. Check once a year the bearings and the surface of the
rotor.
Electric engines
The electric engines are equipped with ball bearings. Maintenance operations of the bearings aren’t
necessary. Check the engine and any noise once a year
.
