9-5. Caution for Ducting Work
• This unit has high static pressure.
In case of small pressure resistance (for instance, a short duct), install an airflow control damper (field supply)
for adjusting airflow volume as airflow volume / airflow noise increases.
• If the air conditioner is to be installed in a room such as an office or meeting room which needs a low sound
level, provide a supply and return sound absorption chamber with an acoustic liner.
• Use a flexible canvas connection or vibration isolation hanger (field supply) to break transmission of
mechanical vibration of the unit.

CAUTION
• Use incombustible duct materials.
• Use thermal insulation to prevent duct condensation.
• An air filter (field supply) must be installed at the air intake side.
If not installed, the heat exchanger will get dirty and the unit will reduce the quality.
• Obtain and install an air filter (field supply) which can easily wash away the dust by lukewarm, soapy
water orsuck up with a vacuum cleaner.
• Clean the air filter periodically to collect dust and other particles from the air.
• Use duct static pressure within a range of specification value.
