TECHNICAL MAINTENANCE
Regular technical supervision and maintenance of the unit are required to
ensure the product long service life and non-stop operation.
Disconnect the unit from power mains prior to any maintenance
operations.
Warning! Consider the unit sharp edges! Fulfil maintenance
operations in work gloves!
The recommended unit maintenance periodicity is 3-4 times per year.
The unit technical maintenance includes regular cleaning and other works:
1. Filter maintenance (3-4 times per year).
Dirty filters increase air resistance and decrease supply air. Clean the
filters with a vacuum cleaner or flush those with water. After two consecutive
cleanings the filter must be replaced. Install dry filters only! Contact a local
distributor for the filters stated above in the section «Technical data».
Dirty filters are not considered as a warranty case! Replace
immediately humid and mouldy filters!
