5. Run refrigerant piping as directly as possible and
avoid any unnecessary turns or bends.
6. Condensate piping can be directed through the inside
wall to an approved drain or straight outside.
NOTE: The piping hole for condensate line must slope at a
minimum pitch of
1
/
4
in. per foot to ensure proper drainage.
If proper pitch cannot be achieved, install accessory conden-
sate pump at this time.
III. STEP 3 — MOUNT UNIT
Refer to Fig. 4 for clearances and dimensions. Use mounting
template included inside box to locate mounting bolt holes,
piping holes, electrical connections, and accessory outdoor-
air intake, if used.
Select proper type of hardware from the guidelines below.
See Fig. 5.
A. Wooden Structure
Install hanging bolts on a square wooden piece placed over
beams.
B. Newly Built Concrete Slab
Install hanging bolts with inserts, embedded bolts, etc.
C. Metal Structure
Install hanging bolts utilizing an existing angle or by install-
ing a new support angle.
D. Previously Built Concrete Slab
Install hanging bolts with expansion anchor.
E. To Mount Unit:
1. Remove mounting bracket and reinstall the 2 hex-
head bolts (factory-supplied) into each side of indoor
unit as shown in Fig. 6. Allow approximately
3
/
8
-in.
space between bolt head and unit.
2. Determine installation position, paying particular
attention to piping lengths, wiring connections, clear-
ances, etc. See Fig. 3 for connection locations, Fig. 4
for clearances, and Fig. 7 and 8 for bolt locations.
3. Open knockout if right-side piping connections are
required (Fig. 9), by removing the pre-slit portion in
the rear of the right side panel with a saw or cutter
knife.
4. Mount hanging brackets on ceiling (Fig. 10) for either
concealed or exposed bolt hanging position.
5. Lift the unit into place, and fit the hex-head bolts on
sides of indoor unit into mounting slots of mounting
brackets (Fig. 11). Ensure unit is mounted with a
slight tilt to the right rear side for proper drainage.
6. Tighten indoor unit hex-head bolts securely.
CAUTION: Solid structure in ceiling must be used
due to the weight of the unit.
