•
Use field-supplied flexible ducts to avoid abnormal acoustic vibrations.
•
RPI units are supplied with a standard air filter on the suction side. This filter is supplied for cases where no suction duct is applied (or
when the duct is very short).
Secure the flexible 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 filter.
2
Where the suction duct is used, fit the air filter at the suction duct
inlet point, removing the standard air filter from the unit. This air
filter must be field-supplied or a factory-adapted one must be
used.
