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 lter.
2 Where the suction duct is used, t the air lter at the suction
duct inlet point, removing the standard air lter from the unit.
This air lter must be 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 lter downwards.
