Air Duct Connection; Maintenance Of The Suction Air Filter - Hitachi RCI-1.0FSN3 Service Manual

2 Unit installation

2.6.3 Air duct connection

N O T E
• 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.

2.6.4 Maintenance of the suction air filter

Simply remove the set screws from the bar -1- (4 screws) and
remove it to pull the filter downwards.
