2. DRILL A HOLE IN WALL FOR
INTERCONNECTING PIPING,
DRAIN & WIRING
• Decide the position of the hole for piping
according to the location of mounting plate.
• Drill a hole in the wall. The hole should tilt a
little downward toward outside to allow for
appropriate water drainage.
• Install a sleeve through the wall hole to keep
the wall tidy and clean.
3. PIPING AND DRAIN HOSE
CONNECTIONS TO INDOOR UNIT
• Run the piping (liquid and gas pipe) and cables
through the wall hole from outside or put them
through from inside after indoor piping and
cables connection is complete to connect to
the outdoor unit.
• Decide whether to cut the unloading piece off
in accordance with the piping direction.

Drainage structure
NOTE:
When installing the pipe at the
directions 1, 2 or 4, cut the corresponding
unloading piece off the indoor unit base.
NOTE:
Both sides drainage structure is
standard. For both sides drainage structure,
it can be chosen for right, left or both sides
drainage connection. If choosing both sides
drainage connection, another proper drain
hose is needed as there is only one drain
hose offered by factory. If choosing one side
drainage connection, make sure the drain
hole on the other side is well plugged.
• After connecting the piping , install the
drain hose. Then connect the power cords.
After connecting, wrap the piping, cords
and drain hose together with thermal
insulation materials.
NOTE:
Dimensions are in “inch” unless otherwise stated in the table.

• PIPING JOINTS THERMAL INSULATION:
Wrap the piping joints with thermal insulation
materials and then wrap with a vinyl tape.
• PIPING THERMAL INSULATION:
a. Place the drain hose under the piping.
b. Insulation material uses polythene foam
over 6mm in thickness.
NOTE:
Drain hose is prepared by installer.
• Do not arrange the drain pipe in a way that
leaves it twisted, sticking out or waving around.
Do not immerse the end of it in water.
• If an extension drain hose is connected to the
drain pipe, make sure to insulate when passing
along the indoor unit.
• When the piping is directed to the right, piping,
power Cord and drain pipe should be thermal
insulated and fixed onto the back of the unit
with a piping fixer.

PIPING CONNECTION:
a. Before unscrewing the big and the small sealing caps, press the small sealing
cap with the finger until the exhaust noise stops, and then loosen the finger.
b. Connect indoor unit pipes with two wrenches. Pay special attention to the
allowed torque as shown below to prevent the pipes, connectors and flare
nuts from being deformed and damaged.
c. Pre-tighten them with fingers at first, then use the wrenches.
If you don't hear the exhaust noise, please contact with the merchant.
