VENTILATION THE RIGHT WAY

12.3.7 Resetting the filter change indicator
After every air filter change, the filter change indicator must be reset in order to restart
monitoring of the period since the last air filter change. The procedure is as follows:
► Press key 1 (item 1 in Fig. 12 on page 23) for roughly 5 seconds.
The ventilation unit will beep three times as confirmation. Monitoring of the period
since the last air filter change is now restarted.
13 Cleaning
WARNING
► Switch off the power to the ventilation unit before cleaning.
► When cleaning, make sure that no moisture penetrates into the inside of the
housing.
► Never use a high pressure cleaner, steam cleaner or steam jet.
The ventilation unit is made of high quality plastic and requires little care.
► Wipe the outer surfaces from time to time with a soft, damp cloth. Use mild soapy
water. A commercially available plastic cleaner can be used for particularly stubborn
dirt.
NOTICE
► Never use acidic, corrosive or abrasive cleaning agents.
Maintenance of the M-WRG-II series of units is described in separate maintenance
instructions (in preparation).
