TECHNICAL MAINTENANCE
Maintenance operations of the unit are required 3-4 times per year. Maintenance includes regular
cleaning and the following operations:
1.
Filter maintenance.
Filter Maintenance Frequency:
•
DUO/6Т901580 - 3-4 times a year;
•
DUO/6M901580B - according to the fi lter service alert generated every 3,000 operating hours
(according to the integrated hour meter).
Dirty fi lters increase air resistance in the system and reduce supply air volume. The fi lters require
cleaning not less than 3-4 times per year. Dirty fi lters can be restored with a vacuum cleaner or replaced.
Contact the unit Seller to purchase new fi lters.
The steps to replace the fi lters are as follows (Fig. 8):
1. Release the latches and remove the bottom panel.
2. Turn the latches and remove the condensate drain pan(s).
3. Turn the latches and remove the fi lters.
2.
Fan inspection (once a year).
Even regular technical maintenance of the fi lters may not prevent dust accumulation on fan part
surfaces resulting in overall unit performance drop and less fresh air supplied to the premises.
Clean the fans with a cloth or a soft brush. Do not use water, aggressive solvents, sharp objects etc.
as they may damage the impeller.
The steps to replace the fi lters are as follows (Fig. 8):
1. Release the latches and remove the bottom panel.
2. Turn the latches and remove the condensate drain pan(s).
3. Turn the latches and remove the heat exchangers.
3.
Condensate drainage check (once a year).
The condensate drainage (the drain line) may get clogged with the hard particles contained in the
extract air. Check the drain line functionality by fi lling the unit drain pan with water and clean the siphon
and the drain line if necessary.
4.
Fresh air supply check (twice a year).
The supply grille may get clogged with leaves or other objects resulting in the unit performance
drop and less fresh air supplied to the premises. Check the supply grille twice a year and clean it if
necessary.
5.
Ductwork system check (every 5 years)
Even if you follow all the listed maintenance guidelines, some dust can accumulate inside the air
ducts and reduce the unit performance. Duct maintenance means regular cleaning or replacement.
6.
Control unit maintenance (if necessary).
The control unit maintenance must be performed by an expert qualifi ed for unassisted
operations with electrical installations up to 1,000 V after reading and understanding the user’s
manual. Disconnect the unit from the power mains prior to the control unit maintenance.
The control unit maintenance steps are as follows (Fig. 9):
1. Undo the eight self-tapping screws securing the control unit cover.
2. Remove the control unit cover.
