Installation of the unit without duct may lead capacity degradation caused by short circuit, operation
stop by high pressure protection, or other malfunction.
¢ About the duct
The duct needs to be purchased locally. When installing the duct, be careful of the followings:
• Do not cover the service panel. If covered, the panel cannot be opened for servicing.
• Screw holes for installing the duct are placed on the front panel. Fix the duct by using a Ø5 mm
tapping screw. (Refer to following diagram for the location.)
