Once the unit is hung, you may install any additional ducting required. The diagram below

INSTALLATION TIPS
• Air filters help remove dust and particles from the circulating air. They should be installed on
the air inlet side according to the size of the inlet on the unit.
• Vibration dampeners are recommended to be installed between the unit and the ductwork.
They will decrease vibrations and noise coming from the unit. They also provide some flexibility
when installing and positioning the ductwork.
• The air inlet and air outlet should be far enough apart to avoid short-circuiting the air flow and
provide proper circulation in the room.
• Do not place the connecting duct weight on the unit. Provide proper support for the ductwork
independent of the unit supports.
• All ductwork should be properly insulated to prevent condensation.
• Refer to the following static pressure guidelines when installing the indoor unit:
Model Static Pressure
