Installation manual
6.4 Shared exhaust duct
It is recommended that each machine is connected to a separate exhaust duct and fully inserts into the exhaust
duct.
When several machines shall use the same exhaust duct , the exhaust duct must increase after each machine.

The exhaust duct diameter must not be reduced.
The multiple dryers must have separate backdraft dampers when connected through a shared exhaust duct.
If not, the load in the dryer will be affected by other dryers and become moist.
6.5 Exhaust dimensioning
It is important that the machine has correct air volume compared to each machines power. If the air flow is smaller or
larger this will result in a longer drying period.
If the outlet pipe is long or the ventilation is not properly designed we recommend to clean the outlet pipes periodi-
cally. The exhaust pipes shall be short in order for the machine to work in the best way.
Failure to install back draft dampers in shared dryer exhaust ducts can cause hazardous conditions such backflow
of combustible gases. Single or independent dryer venting is recommended. It is suggested that the use of 90° turns
be avoided; use 30° and/or 45° bends.
It is recommended that exhaust or booster fans not be used in the exhaust ductwork system. If an exhaust booster
fan is required, care must be taken to meet all other installation requirements.
The exhaust duct must be designed the static back pressure measured from the exhaust outlet connection does not
exceed the maximum allowable back pressure specified in Technical data.
