Evacuation System If Several Ironers Are Connected To A Common Evacuation Duct - Electrolux IC4 4819 FFS Service Manual

10
Evacuation system if several ironers are connected to a common
evacuation duct (except for the gas heating machines)
If several dryer ironers are installed with a common evacuation duct, the cross-section of the
evacuation duct must increase as a function of the number of installed machines so that each of
them operates at the same value of air resistance.
Use elbows (and not Tees) to allow
the air to pass forwards.
The simplifi ed fi gure below shows
the principle on which the evacuation duct
shape is designed.
Number of ironers
Outlet diameter of the exhaust pipe in (mm)
Ventilation aperture required section
The indicated evacuation diameter is the dryer outlet diameter.
Cross-sections of ducts between dryers and the outside of the building must be designed taking
account of the fl ow and the allowable pressure loss on each machine and the routing of ducts
(elbows and lengths).
Please call us if you are in any doubt about the layout of your exhaust device if you are
modifying an existing installation.
