OUTDOOR UNITS 6 Outdoor units may be connected to
indoor units using field-supplied robing of retiigerant grade
and condition. See Table 3 tbr correct line sizes. Do not use less
than 10 ft of interconnecting robing.

INSTALLING THE INDOOR UNIT BODY TO THE
WALL HANGING BRACKET
1. Pass the pipes through the walt sleeve mid then hook the
indoor unit body on top of the wall hanging bracket.
2. For left-hand piping, hang the unit on top of the wall
hmlging bracket and incline the unit using a toot such as a
screwdriver set between the middle area of the body mid
bottom right of the walt hanging bracket. Connecting the
pipe can be done more easily if the unit is inclined.
3. Fix the bottom part of the unit to the walt hanging bracket
by pushing it carethlty until the two bracket hooks fit into
the marked places at the base of the unit until it snaps into
place. Refer to Fg. 11.
NOTE:
f Do not crush or kink the indoor piping. Avoid sharp bends
with a bend radius of less than 4 inches.
f Do not over bend the sane part of the pipe lfequently.
f Do not remove the flare nut fiom the indoor unit pipe until
the piping is connected.
DO NOT BURY MORE THAN 36 IN. OF REFRIGER-
ANT PIPE IN THE GROUND. If any section of pipe is
buried, there must be a 6-in. vertical rise to the valve
connections on the outdoor unit. If more than the
recolrnnended length is buried, refiigermlt may migrate to
cooler, buried section during extended periods of system
shutdown. This causes reti-igerant slugging mid could
possibly daanage the compressor at start-up.
NOTE: Both mb:ed phase and vapor refiigerant lines must be
insulated.
If either retiigerant tubing or indoor coil is exposed to the
annosphere, the system must be evacuated follc_ving good
reli-igeration practices.
Run refiigerant tubes as directly as possible, avoiding
unnecessary turns aaldbends. Suspend refi-igerant tubes so they
do not damage insulation on vapor tube and do not transmit
vibration to structure. Also, when passing reti'igermlt robes
throu_l a wall, seal the opening so that vibration is not trans-
mitted to structure. Leave some slack in reiiigerant robes
between structure mid outdoor unit to absorb vibration.
MAKE PIPING SWEAT CONNECTIONS 6 Remove plas-
tic caps tiom liquid and suction sen:ice valves. Use refi-igerant
grade tubing.
Position tube end downward and cut the tube to the request-
ed length. Remove the burrs with a reamer. See Fig. 12.
NOTE: Oil in the compressor is extremely susceptible to mois-
ture absorption. Keep ends of robing sealed during installation.
Remove flare nuts tiom the unit connections and place them
on the robe end. Flare the robe with the flaring tool. The flare
end must not have aalyburrs or imperfections. The length of the
flared walls must be uniibnn. See Fig. 13.
