The Indoor Unit
There is enough room for installation and maintenance.
The ceiling is horizontal, and its structure can endure the weight of the indoor unit.
The air outlet and the air inlet are not impeded, and the influence of external air is the least.
The air flow can reach throughout the room.
The connecting pipe and drainpipe could be extracted out easily.
There is no direct radiation from heaters
INSTALLATION PLACE
Location in the following places may cause malfunction of the machine. (If unavoidable,
please consult your local dealer.)
a. There exists petrolatum.
b. There is salty air surrounding(near the coast).
c. There is caustic gas(the sulfide, for example) existing in the air (near a hot spring).
d. The Volt vibrates violently(in the factories).
e. In buses or cabinets.
f. In kitchen where it is full of oil gas.

NOTE:
Remark per EMC Directive 89/336/EEC
For to prevent flicker impressions during the start of the compressor (technical process),
following installation conditions apply.
1. The power connection for the air conditioner has to be done at the main power distribution.
The distribution has to be of a low impedance, normally the required impedance reaches
a 32A fusing point.at
2. No other equipment has to be connected with this power line.
3. For detailed installation acceptance, please refer to your contract with the power supplier
restrictions do apply for products like washing machines, air conditioners or electrical if
ovens.
4. For power details of the air conditioner, refer to the rating plate of the product.
5. For any question contact your local dealer.

INSTALL THE CONNECTING PIPE
The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as
the connections of the indoor unit.
Hard PVC binder must be used for pipe connection, and make sure there is no leakage.
With the connection part to the indoor unit, please be noted not to impose pressure on the
side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100, there should not be any win
ding.
The total length of the drain pipe when pulled out traversely shall not exceed 20m, when
the pipe is over long, a prop stand must be installed to prevent winding.
Refer to the figures on the right for the installation of the pipes.

CAUTIONS
2. Drainage test
Check whether the drainpipe is unhindered
New built house should have this test done before paving the ceiling.
Check whether the height drop between the indoor unit and outdoor unit, the length of
refrigerant pipe, and the number of the bends meet the following requirements:
The max height drop...................................................................................................20m
(If the height drop is more than 10m, you had better put the outdoor unit over above the
indoor unit.)
The length of refrigerant pipe.......................................................................less than 30m
The number of bends....................................................................................Less than 15
Page 8
Do not let air, dust, or other impurities fall in the pipe system during the time of installation.
The connecting pipe should not be installed until the indoor and outdoor units have been
fixed already.
Keep the connecting pipe dry, and do not let moisture in during installation.
1) Connect the indoor unit at first, then the outdoor unit.
,
Bend the tubing in proper way. Don t harm them.
The Procedure of Connecting Pipes
1. Measure the necessary length of the connecting pipe, and make it by the following way.
Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4
rounds with hands before fasten the flare nuts. (Refer to chart 11)
Be sure to use two wrenches simultaneously when you connect or disconnect the pipes.
Cautions
2) The stop valve of the outdoor unit should be closed absolutely (as original state). Every
time you connect it, first loosen the nuts at the part of stop valve, then connect the flare
pipe immediately (in 5 minutes). If the nuts have been loosened for a long time, dusts
and other impurities may enter the pipe system and may cause malfunction later. So
please expel the air out of the pipe with refrigerant before connection.
o
The bending angle should not exceed 90 C
Bending position is preferably in the bendable pipe. The larger the better it is .
Do not bend the pipe more than three times.
Be sure to use the same insulating materials when you buy the brass pipe. (More than
9mm thick)
Cut out a desired concave at the bending part of the insulating pipe.
Then expose the pipe(cover it with tapes after bending).
To prevent collapsing of deforming, please bend the pipe at its biggest radius.
Use bender to get a small radius pipes.
3) Expel the air (refer to the Expel The Air ) after connecting the refrigerant pipe with the
indoor unit and the outdoor unit.
Then fasten the nuts at the repair-points.
Notices For Benable pipe.
Bend the connecting pipe of small wall thickness.
Use the market brass pipe.

2. Locate The Pipe
1) Drill a hole in the wall (suitable just for the size of the wall conduit, 90mm in general), then
set on the fittings such as the wall conduit and its cover.
2) Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air
in, which will cause water leakage by condensation.
3) Pass the bound connecting pipe through the wall conduit from outside. Be careful of the
pipe allocation to do no damage to the tubing.
3. Connect the pipes.
4. Then, open the stem of stop valves of the outdoor unit to make the refrigerant pipe conne cting the indoor unit with the outdoor unit fluently flow.
5. Be sure of no leakage by checking it with leak detector or soap water.
6. Cover the joint of the connecting pipe to the indoor unit with the soundproof/insulating
sheath (fittings), and bind it well with the tapes to prevent leakage.

1. The air conditioner should use separate power supply with rated voltage
2. The external power supply to the air conditioner should have ground wiring, which is linked
to the ground wiring of the indoor and outdoor unit.
3. The wiring work should be done by qualified persons according to circuit drawing.
4. A leakage protector should be installed according to the National Standard concerning
electrical appliance.
5. Be sure to locate the power wiring and the signal wring well to avoid cross-disturbance and
their contact with connecting pipe or stop value body.
6. The wiring attached to this air conditioner is 10m long. Be sure to prolong it with wiring of
the same type and proper length if necessary. Generally, do not twist two wiring together
unless the joint is soldered well and covered with insulator tape.
7. Do not turn on the power until you have checked carefully after wiring.
