CONNECTION OF THE REFRIGERANT PIPE
Connection of the Refrigerant Pipe
When connecting the pipe to the unit or backout from the unit, use both
a spanner and a torque wrench.
When connecting, smear both inside and outside of the flare nut with
freeze motor oil, screw it by hand and then tighten with a spanner.
Refer to form 1 to check if the wrench had been tightened (too tight
would mangle the nut and lead leakage).
Examine the connection pipe to see if it had a gas leak, then take the
treatment of heat insulation. Only use a median sponge to entwine the
wiring interface of the gas pipe and heat preservation sheath of the gas
collection tube.
DRAINAGE HOSE
1. Install the drain hose.
S
The diameter of the drain hose should be equal or bigger than
the connection pipe's. (The diameter of the polythene pipe:
Outer diameter 1 in (25 mm) Surface thickness
mm).
S
The drain hose should be short and the drooping gradient
should be less than 1/100 to prevent the formation of an air bub-
ble. If the drain hose does not has enough of a drooping
gradient, a drain raising pipe should be added.
S
To prevent a bend in the drain hose, the distance between the
hoisting stand should is 3.28 to 4.92 ft. (1 to 1.5 m) (see Fig.8).
3.28 to 4.92 ft (1 to 1.5 m)

S
Use the drain hose and clamp attached. Insert the drain hose into
the drain vent, and then tighten the clamp.
S
Entwine the big sponge on the clamp of drain hose to insulate
heat.
S
Heat insulation should be applied to the indoor drain hose.

NOTE: Drain Setup pipe
S
The install height of the drain raising pipe should less than 11
in. (280 mm).
S
The drain raising pipe should form a right angle with the unit,
and distance to unit should not beyond 11.81 in. (300mm).

INSTRUCTION
The slant gradient of the attached drain hose should be within 3 in. (75
mm) so that the drain hole does not have to endure unnecessary outside
force.

1. Install the drain hose according to the following process if
several drain hoses join together.

2. Check the smoothness of the drain after the installation.
3. Check the drain state by immitting 36 3/5 in3 (600 cc) water
slowly from the outlet vent or test hole.
4. Check the drain in the state of refrigerating after installing the
electric circuit.

Electrical wiring
NOTE: The power of the entire indoor unit must be connected in the
outdoor unit.
S
About the electrical wiring, see the circuit diagram attached
with the unit.
S
All electrical wiring installation must be done by professional
personnel.
S
Remove the earthing treatment.
Wiring method of connection unit and controller
Connection wiring (communication)
1. Open the electric box cover, drag the wiring (communication)
from rubber plug A, and impact them well individually with an
impact fastener.
2. Wire according to the indoor side circuit diagram.
(1.) Fix the impact fastener after the connection.
(2.) Entwine the small sponge on the electric wire (entwine
to prevent condensation).
(3.) Impact tightly with an impact fastener after connection.
Then fir on the electric box.
(4.) Connect the 3 cord rubber wire to the counter terminal
of the 3 way terminal board.
