2.6.3 Air duct connection
? NOTE
• Use eld-supplied exible ducts to avoid abnormal acoustic vibrations.
• RPI units are supplied with a standard air lter on the suction side. This lter is supplied for cases where no 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.
