Initial start-up and adjustment

Useful hint for adjustment!
☞
The adjustment by means of pressure measurement is explained in the Helios practical workshops, and
this is the easiest way to adjust a KWL EC 270/370 W R/L. In this respect, a pressure measuring
connector must be mounted to each connecting socket/ventilation pipe (approx. 20 cm past the unit
connection), and the pressure hoses must be readily accessible. To balance the whole system, supply
and extract openings should be provided with adjustable elements or valves (accessories). During
extraction of polluted extract air, a filter (accessories) is to be connected. The installation of kitchen
hoods to the system (cause: dirt, fire danger, hygiene) is not permitted. To ensure air circulation within
the room sufficient overflow openings (door gap, door grilles) are to be planned.
All fire regulations must be observed!
Detailed information on the adjustment of KWL wall-mounted units can be found in the
