Replace filters following the next steps:
Carry out filter cloth replacement operations only if you do not suffer from allergies to dust particles. Avoid replacing
filters when people with such allergies are present.
Replace the filter cloth from the filter frame in a well-ventilated area or outdoors.
Before removing the frame with cloth, it is recommended to have an air-tight bag (a plastic carrier bag etc.) ready to
carry the frame to a suitable area to conduct replacement and subsequently use it to dispose of the contaminated
cloth, e.g. with common waste.
When replacing filters, do not remove the unit’s door – use the special cover for filter replacing.
1. Release the filter plugs in the housing until using the product in the package – pull straight on.
Do not pull on the slant!
2. Remove the cover on the unit’s enclosure, start from the bigger recess.
3. Take out the frame with filter cloth.
4. Slide a new filter cloth onto the frame. The fibre is to be slid onto the frame.
5. Properly fitted cloth – the blue / red side faces unit’s ports and the white one the heat recovery exchanger.
6. Fit the filter covers, proceed from one side to another.
7. Press the cover into the unit’s enclosure so that it is flush with the lid’s edge along the entire parameter.
