Initial commissioning 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 rea-
dily 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 suffi-
cient overflow openings (door gap, door grilles) are to be planned.
Any fire regulations must be observed!
Detailed information on the adjustment of KWL wall-mounted units can be found in the Installation and
Operating Instructions "KWL easyControls Initial Commissioning"; No. 82 237!
