For the left-hand and right-hand piping, remove the
rear plate bushing from the left side of the rear plate.
Explain to clients that the rear plate bushing must be
kept as it may be used when relocate the air
conditioner to any other place.
Wind the connective cable, drain hose and wiring with
tape securely, evenly.

When relocate the unit to an other place,
perform evacuation. using vacuum pump .
For the R407C/R410A refrigerant models,
make sure the refrigerant added into the air
conditioner is liquid form in any case.
Caution in Handing the Packed Valve
Open the valve stem until it hits against the
stopper. Do not try to open it further.
Securely tighten the valve stem cap with a
spanner or the link.
Valve stem cap tightening torque.
Using the Vacuum Pump
(For method of using a manifold valve, refer to its
operation manual)
Completely tighten the flare nuts A, B, C, D,
connect the manifold valve charge hose to a
charge port of the packed valve on the gas
pipe side.
Connect the charge hose connection to the
vacuum pump.
Fully open the handle Lo of the manifold valve.
Operate the vacuum pump to evacuate. After
starting evacuation, slightly loose the flare nut
of the packed valve on the gas pipe side and
check that the air is entering. (Operation noise
of the vacuum pump changes and a
compound meter indicates 0 instead of minus )
After the evacuation is complete, fully close
the handle Lo of the manifold valve and stop
the operation of the vacuum pump.
Make evacuation for 15 minutes and more and
check that the compound meter indicates
-76cmHg.
Turn the stem of the packed valve B about
45 counterclockwise, securely tighten the
flare nut after 6-7 seconds.
Disconnect the charge hose from the charge
connection of the packed valve at the gas pipe
side.
Fully open the packed valves B and A.
Securely tighten the cap of the packed valve.

1. Outdoor Installation Precaution
Install the outdoor unit on a rigid base to prevent increasing noise level
and vibration.
Determine the air outlet direction where the discharged air is not
blocked.
In the case that the installation place is exposed to strong wind such as
a seaside or high position, secure the normal fan operation by putting
the unit lengthwise along the wall or using a dust or shield plates.
Specially in windy area, install the unit to prevent the admission of wind.
If need suspending installation, the installation wall should be solid brick, concrete or the same
intensity construction, or actions to reinforce, damping, supporting should be taken. The
connection between bracket and wall, bracket and the air conditioner should be firm, stable and
reliable.
If need suspending installation, the installation bracket should accord with technique requirement in
the installation bracket diagram.
2. Drain Elbow Installation
Fit the seal into the drain elbow, then
insert the drain elbow into the base pan
hole of outdoor unit, rotate 90
to
securely assemble them. Connecting
the drain elbow with an extension drain
hose (Locally purchased), in case of
the water draining off the outdoor unit
during the heating mode

1. Cut a pipe with a pipe cutter.
2. Insert a flare nut into a pipe and flare the
pipe.

1. Remove the cover control from the
unit by loosening the 3 screws.
2. Dismount caps on the conduit panel.
3. Temporarily mount the conduit tubes
(not included) on the conduit panel.
4. Properly connect both the power supply
and low voltage lines to the corresponding
terminals on the terminal block.
5. Ground the unit in accordance with local
codes.

WARNING
Be sure to comply with local codes while
running the wire from the indoor unit to
the outdoor unit.
Every wire must be connected firmly.
No wire should be allowed to touch
refrigerant tubing, the compressor
or any moving parts.
Loose wiring may cause the terminal to
overheat or result in unit malfunction.
A fire hazard may also exit. Therefore,
be sure all wiring is tightly connected.
Note : To prevent wires loosening or leaving the Cord
Clamp, please select proper cord diameter to fill the
holes on the cord clamp.

Perform test operation after completing gas
leak check at the flare nut connections and
electrical safety check.
Check that all tubing and wiring have been
properly connected.
Check that the gas and liquid side service
valves are fully open.
1. Connect the power, press the ON/OFF
button on the remote controller to turn the
unit on.
2. Use the MODE button to select COOL, HEAT
(cooling & heating modles only ), AUTO and
FAN to check if all the functions works well.
3. When the amient temperature is too low
(lower than 17 C), the unit can not be
contro lled by the remote controller to run
at cooling mode, manual operation can be
taken. Manual operation is used only when
the remote controller is disable or mainten-
ance necessary.
Hold the panel sides and lift the panel up to
an angle until it remains fixed with a
clicking sound.
Press the Manual control button to select
the AUTO or COOL, the unit will operate
under Forced AUTO or COOL mode
(see User Manual for details).
4. The test operation should last about
