Installation Manual For Indoor Unit

The length difference among every duct is limited below 2:1.

Reduce the length of duct as possible as can.

Reduce the amount of bend as possible as can.

Use heat insulation material to bind and seal the part connecting main unit and the flare part of air discharging duct. Perform duct installation work, before the fitment of ceiling.
