When Installing…
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents
water damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.
…In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.

tionary tabs from the frame. (Fig. 7)
(3) Remove the rear panel.
Tubing can be extended in 5 directions (KHS0951, KHS1251 and
KHS1852) as shown in Fig. 8a or 8b. Select the direction you need
providing the shortest run to the outside unit.
3-2. Make a Hole
(1) Place the rear panel from the indoor unit on the wall at the loca-
tion selected. Make sure the panel is horizontal, using a carpenter’s level or tape measure to measure down from the ceiling.
Wait until after cutting the hole before attaching the rear panel to
the wall.
(2) Determine which side of the unit you should make the hole for
tubing and wiring. (Fig. 9)
(3) Before making the hole, check carefully that no studs or pipes
are directly run behind the spot to be cut.
Fig. 6
Fig. 7
KHS0951, KHS1251
● Also avoid areas where electrical wiring or conduits are
located.
● Switching drain hose and drain cap
(a) Locate the drain hose and the drain cap. (Fig. 8c)
(b) Remove the drain hose on the right side by pushing and
turning the hose connector counter-clockwise to release it.
(Fig. 8c)
(c) Apply moderate force to pull off the drain cap on the left
side. (If you cannot pull it off by hand, use a long-nose pliers.)

a) If Wooden Wall
(1) Attach the rear panel to the wall with the 10 screws
provided. (Fig. 13)
If you are not able to line up the holes in the rear
panel with the beam locations marked on the wall,
use rawl plugs or toggle bolts to go through the
holes on the panel or drill 3/16 in. (5 mm) dia. holes
in the panel over the stud locations and then mount
the rear panel.
(2) Double check with a ruler or carpenter’s level that
the panel is level. This is important to install the unit
properly. (Fig. 14)
(3) Make sure the panel is flush against the wall. Any
space between the wall and unit will cause noise
and vibration.
b) If Block, Brick, Concrete or Similar Type Wall
Make 3/16 in. (4.8 mm) dia. holes in the wall. Insert
rawl plugs for appropriate mounting screws. (Fig. 15)
