►
Loosen the counternuts with a screw wrench .
►
Correct the height of the feet .
►
Screw the counter nuts back up . Hold the appliance
feet firmly while doing so to prevent the height shift-
ing .
Fresh air connection (Option)
A fresh air pipe with a diameter of 160 mm or 200
mm can be connected if there is a fresh air connec-
tion (with overflow opening) . The following conditions
must be satisfied so that fresh air can be supplied to
the appliance:
Air pressure at the air intake
►
Maximum 0 Pa (no excess pressure)
►
Minimum – 20 Pa (under-pressure)
Exhaust air duct
For the exhaust air duct you can use all normal propri-
etary products, such as:
•
Plastic tubes
•
Flexible ducts or tubes
•
Galvanised metal ducts or tubes
•
Connecting, transition or deflection pieces for flat duct
and tube systems
•
Wall boxes for exhausting into the open air or into a
ventilation shaft .
Notice
The material must be moisture-resistant and ther-
mally stable up to 80 °C .
Pressure loss
The nature and length of the exhaust air duct, in parti-
cular knee pieces or curves with small radii, impede the
flow of air .
►
Be sure to obstruct the air flow as little as possible
and keep pressure loss (resistance) minimal .
Depending on the material used, the air is hindered
substantially or less substantially as a result of fricti-
on on the inside of the tubing .
►
Use tubes with a large inner diameter, smooth inner
surface and the shortest possible overall length .
Additional fittings, such as curves, bends, elbows and
wall boxes with grids or backpressure flaps increase
the resistance .
Notice
You will achieve optimal performance of the exhaust
air duct by observing the following points:
•
Large internal diameter
•
Short overall length
•
Avoid tube bends/elbow joints
Calculating the pressure loss
Calculate the loss of pressure using the correspon-
ding values for your appliance type .
Notice
To ensure the minimum required air flow, the total
pressure loss must not exceed the value of 200 Pa .
