Installation of duct flange
Installation of duct (should be prepared locally)
Install the optional duct flange referring to
the installation manual provided with it.
In case that a duct fan is used, be sure to make it linked
with the air conditioner when outside air is taken.
Do not run the duct fan only. It can cause dew drop.
Prepare a duct of which inner diameter fits into the outer diameter of
the duct flange.
In case that the environment above the ceiling is high temperature
and high humidity, wrap the duct in a heat insulator to avoid causing
dew drop on the wall.
A duct must be procured at local site for dust collecting filter since
the dust contained in the outside air taken into the indoor unit is not
removed without such filter.

Preparation for temporarily hanging the grille
Temporary installation of the grille
Check that the 2 temporary hanging hooks on the grille are in the raised position.
<Grille hook is in the raised position>
<A grille in temporary installation>
<Grille hook is in the lowered position>
Align the label attached on the drain pipe corner of the Multi-functional
casement to the corner with the round hole of the grille, and temporarily
install the grille by latching the grille hooks onto the projections on the
Multi-functional casement 1.
Notes:
1. Make sure electrical wires are not caught between the Multi-functional
casement and the grille.
2. Never force pressure on the grille during the temporary installation.
It may result in accident and damage.
