1
Install the indoor unit temporarily.
• Secure the unit and supporting plate (field supply) at
four places with M12 screws. (Refer to Fig.7)
• Fit the supporting plate into the suspension bolt.
(Refer to Fig.8) Use washers to secure and tighten
both the upper and lower nuts to the suspension
bolt.
2
Adjust the unit to the preset height.
3
Make sure that the unit is level.
• Adjust the unit using a level gauge. If it is installed
unevenly, water may leak from the unit.
• When making adjustments, test all four corners of
the unit with the level gauge or use a vinyl tube filled
with water.
4
Secure and tighten the upper nuts.
5
Be sure to completely insulate the duct to be con-
nected (field supply) and the connecting joint on
the main unit body.
• Please use a level gauge or
a soft vinyl tube filled with
water to determine the hori-
zontal position of the unit, so
that its inclination angle with
the water drainage hole and
the air intake side does not
exceed 1°.
• Place the drainage hole and
the air intake side at a higher
position in order to avoid
water leakage.
• The difference of height between end faces of
the product shall be adjusted as follows.
