The fan is secured to a base by M8 pin bolts and nuts (4 pcs) in
mounting holes across antivibration mountings, included in deliv-
ery (see 3.1 Design, part 5). The base must be level and stable.
The fan must only be mounted to a horizontal plane.
The fan has three possible outlet directions (left/right/up), up-
wards as standard. Outlet direction can be changed by detaching
the standing skids (see 3.1 Design, part 4) and placing them to
desired side of fan casing (fixed with M8 bolts). Lower cleaning
hatch handle must be removed.
5.1.1 DISMANTLING THE FAN
If the final installation site is difficult to access, the fan has a split
casing as standard for easier transport.
If the fan has been in use and will be removed and dismantled,
make sure that the fan is disconnected from mains (supply- and
control cables detached) and ducting before beginning the dis-
mantling work.
1. Install support stands to back plate and standing skids with
M8 bolt and self-drilling screw. Stands are delivered loose with
the fan.
2. Detach the outlet connection by removing self-drilling screws.
