[Installation directly to a wall]
Refer to Fig. A for the installation hole dimensions of the wall
hook bracket.
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.
(1) 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.)
(2) For a concrete wall, embed anchor bolts (10 mm dia.) into
the wall at the wall hook bracket holes (11 × 43 mm hole
and 11 × 94 mm hole).
(Allow the anchor bolts to stick out at least 18 mm from
the wall. Use 2 bolts for flat concrete wall and 4 bolts for
blister concrete wall.)
(3) Install the nuts to the anchor bolts through the wall hook
bracket.
(4) Finally tighten the bolts and wood screws after confirming,
using the level indicator, that the clamp is horizontal.
WARNING
• Install the wall hook bracket so that it is correctly
po si tioned hori zon tally and vertically. If the wall hook
bracket is tilted, wa ter will drip to the floor.
• As the weight of the indoor unit is 15 to 18 kg, it should
be installed after properly examining the place where it is
in tended to be in stalled. 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.
