TROUBLESHOOTING
The unit technical maintenance consists in the periodic cleaning of the
unit surfaces and cleaning or replacement of the filters. Remove dust
with a soft brush, cloth or compressed air. Do not use water, abrasive
detergents, solvents, sharp objects.
1. Fan maintenance (once a year).
•
Remove the screw in the bottom part of the fan grille, remove and
clean the grille.
•
Disconnect the wires from the ventilation unit by using the
connectors.
•
Remove the four screws and take off the ventilation unit.
•
Clean the impeller blade.
2. Regenerator and filter maintenance (4 times a year).
•
Take off the ventilation unit. Pull the cord to remove the regenerator
and the filter from the air duct. Do not let the regenerator fall down.
•
Clean the filter as often as required, but at least once in three
months. To clean the filter flush it under running water or use a
vacuum cleaner. Let the filter dry and install the dry filter inside the
air duct. Contact a local distributor for the filters stated above in the
section «Technical data».
•
Even regular filter maintenance may not completely prevent the
dust ingress into the regenerating unit. Clean the regenerator with
a vacuum cleaner at least once a year.
3. Outer ventilation hood maintenance (once a year).
The outer ventilation hood may get clogged with leaves and other objects
that reduce the unit air capacity.
Check the outer ventilation hood twice a year and clean it as often as
required.
Cleaning of the outer ventilation hood:
•
remove the front part of the outer ventilation hood:
•
clean the outer ventilation hood and the air duct.
WARNING!
Disconnect the unit from power mains prior to maintenance operations!
