[Installation directly to a wall]
Before fastening the wall hook bracket to the wall with the screws, level it
by tapping the hook at the center of bracket to the wall with the handle of
a screwdriver.
• Fasten the wall hook bracket to the wall with 6 or more screws and
anchor bolts through the holes near the outer edge of the bracket.
• Do not install the wall hook bracket at only one place or at an angle. For
a concrete wall, embed anchor bolts (10 mm dia.) into the wall at the
wall hook bracket holes (11 × 43 mm dia. and 11 × 94 mm dia. (Fig. 6)).
Allow the anchor bolts to stick out at least 18 mm from the wall. (Fig. 7)
Install the unit to the anchor bolts with nuts through the wall hook bracket.
Use 2 bolts for concrete wall and 4 bolts for blister concrete wall (Fig. 8).
• Finally tighten the bolts and tapping screws after confirming, using the
level indicator, that the clamp is horizontal.

WARNING
(1) Install the wall hook bracket so that it is correctly posi-
tioned horizontally and vertically. If the wall hook
bracket is tilted, water will drip to the floor.
(2) As the weight of the indoor unit is 15 to 18 kg (33 to 40
lbs), it should be installed after properly examining the
place where it is intended to be installed. If the place is
not strong enough, a plank or girder should be used to
make the place sufficiently strong so that the wall can
support the weight.
