NOTE
• Excessive torque may cause gas leakage. When
extending the pipe with welding or brazing, ensure
that nitrogen is used during the welding or brazing
process. The joint must be accessible and serviceable.
CAUTION
• Tighten the flare nut at the specified torque. If the flare
nut is over-tightened, it may break to cause leakage of
refrigerant gas.
Step 2.8 Fixing the installation plate
You can install the indoor unit on a wall, window frame, or
gypsum board.
WARNING
• Make sure that the wall, window frame, or gypsum
board can withstand the weight of the indoor unit. If
you install the indoor unit in a place where it is not
strong enough to withstand the unit's weight, the unit
could fall and cause injury.
When fixing the indoor unit on a wall
Fix the installation plate to the wall giving attention to the
weight of the indoor unit.

When fixing the indoor unit on a window frame
1. Determine the positions of the wooden
uprights to be attached to the window
frame.
2. Attach the wooden uprights to the window
frame giving attention to the weight of the
indoor unit.
3. Attach the installation plate to the wooden
upright using tapping screws.
When fixing the indoor unit on a gypsum board
1. Use stud finder to find out locations of the
studs.
2. Fix the plate hanger on two studs.
CAUTION
• If you fix the indoor unit on a gypsum board, use
only specified anchor bolts on reference positions.
Otherwise, the gypsum surrounding the joints may
crumble over time and cause the screws to be
loosened and stripped. This may lead to physical injury
or equipment damage.
• Search for other spots if there are less than two studs,
or the distance between the studs are different from
the plate hanger.
• Fix the installation plate without inclining to one side.
