(1) Install the wall hook bracket so that it is correctly
positioned 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 37 to 44 Ibs (17 to
20 kg), it should be installed after properly examin-
ing 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.
[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 (12 x 18 mm dia.). Allow the anchor bolts to stick
out at least 18 mm from the wall.(Fig.8)
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.
• Finally tighten the bolts and wood screws after con-
firming, using the level indicator, that the clamp is hor-
izontal.
IInstall the wall hook bracket horizontally
and perpendicularly. If the wall hook
bracket is tilted, water will drip to the
floor.
