Basic instructions, filter replacement, maintenance and cleaning

3.1.
 Maintenance involves visually checking the equipment, regularly replacing filters and cleaning the heat recovery exchanger.
 During maintenance observe the rules of personal hygiene and use protective equipment (a face mask, packaging for
contaminated filters).
Before starting maintenance of the unit, always disconnect the equipment from power supply by unplugging the plug

from the power socket.
 During maintenance observe safety instructions contained in the manual ("Important notice"), follow the fundamental rules of
safe work and use suitable means of accessing HVAC equipment (ladders, stepladders).

G4 / F7 filter cloth replacement

3.2.
 You should replace the filter cloth only provided that you do not suffer from allergic reactions to dust particles. Do not conduct
replacement when people with such a level of sensitivity are present.
Replace the filter cloth from the filter frame in a well-ventilated area or out of doors.

 Before removing the frame with cloth, we recommend that you should 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.
Replacement is carried out depending on the dust load of the ambient environment between every 500 and 2,000 operation

hours (usually approx. 2 - 3 months). The recommended inspection interval is indicated on the controller's display.
