suction duct is applied (or when the duct is very short).
Secure the exible air duct to the outsides of the hoses supplied with the unit.
Bear in mind the following instructions depending on the installation
type:
1 Where the suction duct is not used, keep the standard air îš¿lter.
2 Where the suction duct is used, îš¿t the air îš¿lter at the suction
duct inlet point, removing the standard air îš¿lter from the unit.
This air îš¿lter must be îš¿eld-supplied or a factory-adapted one
must be used.
2.6.4 Maintenance of the suction air lter
Simply remove the set screws from the bar -1- (4 screws) and
remove it to pull the îš¿lter downwards.
