CAUTION
Align pipes to be connected.
Sufficiently tighten the flare nut with fingers,
and then tighten it with a spanner and torque

Install the outdoor unit on a rigid base to prevent increasing
noise level and vibration.
Determine the air outlet direction where the discharged or
radiating 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 shield plates.
Specially in windy area, install the unit to prevent the admission of wind.
If need suspending installation, the installation bracket should accord with technique
requirement in the installation bracket diagram. 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.

When relocate the unit to another place,
perform evacuation using vacuum pump.
Open the valve stem until it hits against the

Perform test operation after completing gas
leak check at the flare nut connections and
electrical safety check.
1. Connect the power, push the ON/OFF
button on the remote controller to begin
testing.
2. Push mode button, select cooling, heating,
fan mode to check if all the functions works
well.
3. If you can't find the Remote controller or the
battery of the Remote controller has given
out, manually operation can be taken for
the moment.
1) Open the front panel of the indoor unit;
push the "COOL" button on the electrical
control box.
2) Connect the power, the air conditioner
begin to operate, check if there is any

1. 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.
2. Connect the charge hose connection to the
vacuum pump.
3. Fully open the handle Lo of the manifold valve.
4. 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 com-
pound meter indicates 0 instead of minus)
5. 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.
6. Turn the stem of the packed valve B about 45
counterclockwise, securely tighten the flare
nut after 6-7 seconds. Make sure the pressure
display in the pressure gauge is a little higher
than atmosphere pressure.
7. Fully open the packed valves B and A.
8. Securely tighten the cap of the packed valve.

2. Connect the connective cables to the terminals as
identified with their respective matched numbers
on the terminal block of indoor and outdoor units.
Connect the ground wire to the ground screw,
the washer under the screw must touch the electr-
ical installation plate.
3. To prevent the ingress of water, from a loop of the
connective cable as illustrated in the installation
diagram of indoor and outdoor units.
4. Insulate unused cords (conductors) with PVC-tape.
Process them so they do not touch any electrical
or metal parts.

CAUTION
1. For the left-hand and right-hand piping, remove
the pipe cover from the side panel.
Explain to clients that the pipe cover must be kept
as it may be used when relocate the air conditioner
to any other place.
2. Wind the connective cable, drain hose and wiring
with tape securely, evenly.
Install the drain hose at the bottom of the connective cable.
Reasonably and carefully arrange and bandage the piping in case
to damage the drain hose and connective piping.
Make sure to run the drain hose sloped downward to drain out the
condensation smoothly.
Never intercross or intertwist power line with any other wiring.
