How to Connect the pipes

Drill a hole in the wall (suitable just for the size of the wall
conduit), 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.
Pass the bound connecting pipe through the wall conduct
from outside. Be careful of the pipe allocation to do on
damage to the tubing.

Connect the pipes. Refer to "How to Connect the pipes" for
details.

Expel the air with a vacuum pump. Refer to "How to expel the
air with a vacuum pump" for details.

open the stop values of the outdoor unit to make the
refrigerant pipe connecting the indoor unit with the outdoor
unit in fluent flow.

Check the leakage. Check all the joints with the leak detector
or soap water.

Cover the joints of the connecting pipe with the soundproof /
insulating sheath (fittings), and bind it well with the tapes to
prevent leakage.

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.

Flaring

Cut a pipe with a pipe cutter.

(refer to fig.22)

Bend the tubing in proper way. Do not harm to them.

Connect the indoor unit at first, then the outdoor
unit.

Too large torque will harm the bellmouthing and too small
will cause leakage. Please determine the torque
according to Table 4.

After the connecting work is finished, be sure to check
that there is no gas leak.

The bending angle should not exceed 90.

Bending position is preferably in the middle of the
bendable pipe. The larger the bending radius the better it
is.

Do not bend the pipe more than three times.

When connecting the flare nut, coat the flare both inside
and outside with either oil or ester oil and initially tighten
by hand 3 or 4 turns before tighting firmly.

Be sure to use both a spanner and torque wrench
together when connecting or disconnecting pipes to /from
the unit.

Drainage test

Inatall the drain joint of the outdoor unit

Check whether the drainpipe is unhindered.

New built house should have this test done before paving
the ceiling.

Remove the test cover, and stow water of about 2000ml to the
water receiver through the stow tube.

( Refer to fig.29 in the

figure page)

Turn on the power, and operate the air conditioner under the
"COOLING" mode. Listen to the sound of the drain pump.
Check whether the water is discharger well (a lag of 1min is
allowed before discharging, according to the length of the drain
pipe), and check whether water leaks from the joints.

Stop the air conditioner, turn off the power, and reset the test
cover to its original position.

Fit the seal into the drain joint, then insert the drain joint into the
base pan hole of outdoor, rotate 90 to securely assemble them.
Connect the drain joint with an extension drain hose (Locally
purchased), in case of the condensate draining off the outdoor
unit during the heating mode.

8. WIRING

CAUTION

The air conditioner should use separate power supply
with rated voltage.

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.

The wiring work should be done by qualified persons
according to circuit drawing.

An all-pole disconnection switch having a cintract
separation of at least 3mm in a poles should be
connected in fixed wiring.

Be sure to locate the power wiring and the signal wring
well to avoid cross-disturbance.

Do not turn on the power until you have checked
carefully after wiring.

NOTE

The drain plug is used to empty the water-receiver for
maintenance of the air conditioner. Please stuff it imposition at
all times during operation to avoid leakage.

The body's pump pipe and the drainpipe (especially the
indoor part) should be covered evenly with the out-let pipe
sheath (fittings) and be bound tightly with the constrictor to
prevent condensation caused by entered air.

To prevent water from flowing backwards into the air
conditioner while the air conditioner stops, please lean the
drainpipe down toward outdoor (outlet-side) at a degree of
over 1/ 50. And please avoid any bulge or water deposit. (
Refer to fig.27.a in the figure page)

Do not drag the drainpipe violently when connecting to
prevent the body from being pulled. Meanwhile, one
supportpoint should be set every 1~1.5m to prevent the
drainpipe from yielding (Refer to fig.27.a in the figure page).
Or you can tie the drainpipe with the connecting pipe to fix
it.(Refer to fig.27.c in the figure page)

In the case of prolonged drainpipe, you had better tighten its
indoor part with a protection tube to prevent it from loosing.

If the outlet of the drainpipe is higher than the body's pump
joint, the pipe should be arranged as vertically as possible.
And the lift distance must be less than 200mm, otherwise the
water will overflow when the air conditioner stops.( Refer to
fig.28 in the figure page)

The end of the drainpipe should be over 50mm higher than
the ground or the bottom of the drainage chute, and do not
immerse it in water. If you discharge the water directly into
sewage, be sure to make a U-form aquaseal by bending the
pipe up to prevent the smelly gas entering the house through
the drain pipe.

NOTE

The power connection for the air conditioner has to be
done at the main power distribution. The distribution has
t o b e o f a l o w i m p e d a n c e , n o r m a l l y t h e r e q u i r e d
impedance reaches at a 32 A fusing point.

No other equipment has to be connected with this power
line.

For detailed installation acceptance please refer to your
power supplier, if restrictions do apply for products like
washing machines, air conditioners or electrical ovens.

For power details of the air conditioner refer to the rating
plate of the product.

For any question contact your local dealer.

Remark per EMC Directive 89/336/EEC
For to prevent flicker impressions during the start of the
compressor (technical process) ,following installation
conditions do apply.
