Initial start-up and adjustment

NOTE

☞

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 200/300 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.

ATTENTION

All fire regulations must be observed!

TIP!

Detailed information on the adjustment of KWL wall-mounted units can be found in the

Installation and Operating Instructions “KWL easyControls Initial start-up”; No. 82 237!

When using a heating coil, the duct system must be provided with temperature-resistant and non-

flammable ducts (e.g. spiral duct) 1m before and after the heating coil.
