operations in work gloves!
QF
WARNING!
Cut power supply to the unit off by turning the automatic electric switch QF to OFF position prior to
any maintenance operations. Take steps to prevent re-activation of the automatic switch.
Fulfil the unit maintenance 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 air capacity of the unit. Clean the filter with a vacuum cleaner or flush it 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!
2. Heat exchanger maintenance (once per year).
The heat exchanger must be regularly cleaned to maintain high heat exchanger efficiency even in case of the regular filter cleaning.
Clean it with warm detergent solution. Remove the heat exchanger from the unit and flush it with warm detergent solution. Install the dry heat exchanger
back to the unit.
3. Fan maintenance (once per year).
The regular filter cleaning may not completely prevent the dust ingress into the unit, which results in the unit capacity decrease.
Clean the fan with a soft cloth or a brush. Cleaning with water, abrasive detergents, sharp object or chemicals is not allowed.
4. Condensate drain system maintenance (once per year).
Extract air particles may accumulate in the condensate drain system and cause its clogging. Pour a drain pan under the unit with water to check free water
flow. Clean a U-trap and the drain system if required.
5. Supply air flow control (twice per year).
Check the supply grille and remove foreign objects to maintain free air intake.
6. Air ducts maintenance (once in 5 years).
The regular unit maintenance in compliance with the above rules may not completely prevent dust ingress into the air ducts which may result in air flow
decrease. The air duct maintenance consist in periodical cleaning or replacement.
7. Exhaust grilles and intake diffuser maintenance (as required).
Remove the exhaust grille and the intake diffuser and flush those with warm detergent solution.
Check the ductworks thread connections periodically.
