NOTES BEFORE INSTALLATION
NOTE
1. Select the correct carry-in path.
2. Move this unit as originally packaged as
possible.
3. If the air conditioner is installed on a metal part
of the building, it must be electrically
insulated according to the relevant standards to
electrical appliances
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 32Afusing poinat t.
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
if restrictions do apply for products like washing
machines, air conditioners or electrical
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.

Please refer to the following figure for the distance
measurement between the screw bolts.
Please install with Ø10 hanging screw bolts.
The handling to the ceiling varies fromthe
constructions, consult the construction personnels
for the specific procedures.
Carry out the pipe and line operation in the ceiling
after finishing the installation of the main body.
While choosing where to start the operation,
determine the direction of the pipes to be drawn
out. Especially in case there is a ceiling, position
the refrigerant pipes, drain pipes, indoor & outdoor
lines to the connection places before hanging up
the machine.
The installation of hanging screw bolts.
1. The ceiling where the works will be done must
be flat. Consolidate the roof beamfor possible
vibration.
2. Cut off the roof beam.
3. Strengthen the place cut off, and consolidate
the roof beam.
OVERHANGING THE INDOOR UNIT
(1)Overhang the indoor unit onto the hanging
screw bolts with block
(2) Position the indoor unit in a flat level by using
the level indicator, unless it may cause leakage.

8. INSTALL THE CONNECTING PIPE
CAUTION
CAUTION
CONNECT THE DRAIN PIPE
1)
CAUTION
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:
Measure the necessary length of the connecting
pipe, and make it by the following way.
Connect the indoor unit at first, then the outdoor
unit.Bend the tubing in proper way. Do not harm to
them.
• Do not let air, dust, or other impurities fall in the
pipe systemduring 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.
The outdoor unit is factory charged with refrigerant.
Some systems require additional
charging of regrigerant depending on pipe lengths.
The additional refrigerant to be charged can be
calculated fromthe following formule:
R = T X (L-5)m
R(g): Additional regrigerant to be carged
T(g): The length of the liquid pipe
L(m):The quantity of charged refrigerant per meter
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 16)
Be sure to use two wrenches simultaneously when
you connect or disconnect the pipes.
The stop value 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 value , then connect the flare pipe
immediately (in 5 minutes). If the nuts have been
loosened for a long time, dusts and other

NOTICE FOR BENDABLE PIPE
BEND THE CONNETCTING PIPE OF SMALL
WALL THICKNESS
Use the market brass pipe
The bending angle should not exceed 90 .
Bending position is preferably in the middle of the
bendable pipe. The larger the bending radius the
Do not bend the pipe more than three times.
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 or deforming, please bend
the pipe at its biggest radius.
Use bender to get a small radius pipes.

Be sure to use the same insulating materials when
you buy the brass pipe (more than 9mmthick).

7)
Drill a hole in the wall (suitable just for the size
of the wall conduit, 90mmin general), then set on
the fittings such as the wall conduit and its cover.
Bind the connecting pipe and the cables
together tightly with binding tapes. Do not let air in,
which will cause water leakage by condensation.
Pass the bound connecting pipe through the
wall conduit fromoutside. Be careful of the pipe
allocation to do no damage to the tubing.
Connect the pipes.
Then, open the stemof stop valves of the
outdoor unit to make the refrigerant pipe
connecting the indoor unit with the outdoor unit
fluently flow.
Be sure of no leakage by checking it with leak
detector or soap water.
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.

(please refer to its manual for the way of using
manifold value)
When you have pumped for over 15 minutes,
please confirm that the indicator of multi-meter is
on 1.0x10 Pa(-76cmHg).
All the stop values should be opened before test
operation. Each air conditioner has two stop
values of different sizes on the side of the outdoor
unit which operate as Lo-stop value and Hi-stop
value, respectively.
Loosen and remove the maintenance nuts of
stop values A and B, and connect the charge hose
of the manifold value with the maintenance
terminator of stop valueA. (Be sure that stop
values A and B are both
closed)
Connect the joint of
the charge hose with the vacuumpump.
Open the Lo-lever of the manifold value
completely.
Turn on the vacuum pump. At the beginning of
pumping, loosen the maintenance terminator nut
of stop valueB a little to check whether the air
comes in (the sound of the pump changes, and
the indicator of compound meter turns below zero).
Then fasten the nut.
When the pumping has finished, close the Lo-
lever of the manifold value completely and turn off
the vacuum pump.
Loosen and remove the quadrangle cover of stop
values Aand Bto open stop value A and B
completely, then fasten them.
Disassemble the charge hose fromthe repair-
mouth of stop value A, and fasten the nut.

CAUTION
Refrigerant volume to be added is calculated
according to outdoor unit installation manual .
Be sure to add refrigerant measuring by a scale.

10. CONNECT THE DRAIN PIPE
1. Install indoor unit drain pipe
CAUTION
The outlet has PTI screw bread, Please use
sealing materials and pipe sheath (fitting) when
connecting PVC pipes.
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.
Check whether the drainpipe is unhindered
New built house should have this test done before
paving the ceiling.

Check the leakage
Insulation
Check all the joints with the leak detector or soap
water.
Be sure to with insulating materials cover all the
exposed parts of the flare pipe joints and
refrigerant pipe on the liquid-side and the gas-side.
Ensure that there is no gap between them.
Incomplete insulation may cause water
condensation.
11. WIRING
Attaching wiring
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. Aleakage 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.
