Connecting the tube curve
Included is a tube curve with a sep­
arate sealing ring, clamping ring and
four screws.
Glue the sealing ring to the flange of
►
the tube curve.
Place the clamping ring over the tube
►
curve.
Fasten the clamping ring and tube
►
curve with four screws to the exhaust
opening.
Exhaust air duct
For the exhaust air duct you can use all
normal proprietary 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 moisture­resist­
►
ant and thermally 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.
Pressure losse through friction
The air is affected by friction on the
inside of the tubes and, depending on
the material used, is obstructed to a
greater or lesser extent.
Use tubes with a large inner diameter,
►
smooth inner surface and the shortest
possible overall length to ensure low
frictional resistance.
Pressure loss through obstacles
Additional fittings, such as curves,
bends, elbows and wall boxes with
grids or backpressure flaps increase
the resistance.
Notice
To obtain optimal performance of the
dryer when installing the exhaust line,
observe the following points
• shortest possible overall length
• largest possible inner diameter
• avoid bends and elbows
