2. Start up and Operation
Please ensure that the M-WRG-S ventilation unit has
been properly installed by an expert, according to the
assembly instructions and that the exterior of the unit
is not damaged. The interior and exterior intakes and
outlets must not be covered or obstructed.
Turn on the M-WRG-S ventilation unit by switching
the Power ON/OFF switch on the left bottom side of
the unit to ON and select a ventilation rate with the
alongside positioned 3-level switch.
To ensure a well ventilated and healthy room climate
it is recommended to run the M-WRG-S ventilation
unit continuously at ventilation level I or II. If
needed, switch for a limited period of time to
ventilation level III.
During the winter season, it is recommended to
ventilate the room once daily for 10 minutes at the
highest ventilation rate (III), in order to avoid any
condensate buildup inside the M-WRG-S ventilation
unit.
Caution: Before turning off the M-WRG-S ventilation
unit while exterior temperatures are below 0°C, the
unit has to be run for a minimum of 10 minutes at
level III for antifreeze protection.
Air flaps:
The air flaps will be automatically opened or closed if
the M-WRG-S ventilation unit is switched ON or OFF.
In case of a malfunction make sure the flaps are not
blocked and repeat once again to switch the unit ON
or OFF. In case of a power outage the air flaps will
be closed automatically
After the M-WRG-S ventilation unit is switched
OFF, please wait a minimum of 15 seconds
before switching it ON again.
