ORDER INSTRUCTIONS
1. Choose: If you want to change the G3 coarse filters more often than the F7 -cassette filters, instead of ordering just the filterset, choose the option: Filterset + 2 extra pcs of G3 coarse filters. This way you add two coarse filters, that are needed for an extra change, to your order.
2. Choose: If you want a better filter of G4 class ( 220 x 260 x 48 mm) for the exhaust air, choose this option.
FILTER CHANGE
The recommended interval for filter changes is 2–3 times a year. In connection to the filter change, clean the ventilation unit and remove possible loose dirt, for example by using a vacuum cleaner. You should also check the condition of the heat exchanger and clean it if necessary with suitable detergent.
