Initial commissioning and adjustment

Useful hint for adjustment!
The adjust ment by means of pressure measurement is explained in the Helios practical workshops, and this is the
easiest way to adjust a KWL EC 200/300 W ET 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 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!
