5. INDOOR UNIT INSTALLATION
〈 It may be easier to install accessories (sold separately) before installing the indoor unit. Refer to the
installation manuals provided to the accessories as well. 〉
As for the parts to be used for installation work, be sure to use the provided accessories and specified parts
designated by our company.
(1) Temporally install the indoor unit.
• Connect the hanging brackets to the hanging bolts. Be sure to use and tighten the nut and washer (11) for
each hanging bracket from both upper and lower sides of the hanging bracket. (Refer to Fig. 5) At that time,
the fall of the washer (11) for the hanging bracket can be prevented if the washing fixing plate (9) is used.

CAUTION
• During the installation work, perform the curing of the air outlet and protect the resin drain pan of
the indoor unit from the intrusion of foreign substances, such as welding spatters.
Otherwise, water leakage may occur as a result of damage, such as hole damage, to the resin drain pan.
(2) Make adjustments so that the unit will be in the right position.
(3) Check the level of the unit.
(4) Remove the washer fixing plates for
the falling prevention of the washers
for the hanging brackets, tighten the
nuts on the upper side, and securely
fix the unit.
CAUTION
• Use the level and check that the unit is installed horizontally. (4-directions)
• In the case of using a vinyl tube in place of the level, put the both edges of the vinyl tube in close contact
with the bottom of the product to make levelness adjustment.
If the unit is installed at a slant with the drain pipe side set high, in particular, the float switch will not operate
normally and water leakage may result.
