8.2 How to replace supply/extract air filter
The bag filter must be changed when necessary, they cannot be cleaned. We recommend ordering original filters from
Systemair. Operation time between filter changes depends on the air quality. A differential pressure transmitter indi-
cates when it is time to change the filters, which will trigger an alarm in NaviPad.
1. Pull out the old filters and replace with new ones.
2. In NaviPad, log in as operator; 1111 (min. level).
3. Press on the alarm symbol
on the control panel.
4. Choose Filter alarm and press acknowledge.
8.3 How to clean NaviPad
Disconnect the NaviPad power cord. Wipe the NaviPad gently with a soft cloth. Remove resistant marks with mild de-
tergent (intended for touch screens) on the cloth, gently wipe the screen. Do not use other cleaning agents (they may
contain ammonia or other additives).
8.4 How to clean the heat exchanger
Caution
Do not use detergent containing ammonia
The heat exchanger is sensitive for impacts. Handle the heat exchanger carefully.
Clean the heat exchanger with hot soapy water. It is also possible to use pressure air, but not with too high pressure.
8.5 Control of the heat exchanger
The rotor bearings are permanently lubricated from factory and should not be re-greased.
Once a year verify that the exchanger rotates with ease
Remove the driving belt and verify that the rotor can be moved by hand.
Replace worn-out heat recovery sealing brushes.
Control the driving belt 4 times a year
Tighten the driving belt if the tension is too low.
Secure that the driving belt follows the tracks.
Replace worn-out driving belt.
