Air conditioners are units that should have the professional technicians do the
installation for you.
This Instruction Guide is the universal-purpose version for the models of split
wall-mounted air conditioners manufactured by our Co. The appearance of the
units that you purchase might be slightly different from the ones described in
the Guide, but it does not affect your proper operations and usage.
Please read carefully the sections corresponding to the specific model you
choose, and keep the Guide properly so as to facilitate your reference at later
time.

Selection of installation positions for indoor unit
*
* To be installed at the position where the air delivered from the unit can reach every corner of
the room;
* To avoid being affected by the outdoor air;
* To avoid blockage to the air inlet or outlet of the unit;
* To avoid too much oil smoke or steam;
* To avoid possible generation, inflow, lingering or leakage of flammable gases;
* To avoid high-frequency facilities (such as high frequency arc welders, etc.);
* To avoid the places where acid solutions are frequently used;
* To avoid the places where some special sprayers (sulfides) are frequently used.
* Not to install a fire alarming device near the air outlet of the unit (during operation, the fire alarm
device might be erroneously triggered by the warm air from the unit);

Make sure of enough space for installation and maintenance.
* To take into consideration the operational convenience and safety in installation, it is recommended
to ensure enough space between the unit and the walls.
*
Height limits of indoor and outdoor units.
* Either the indoor unit or the outdoor unit can be higher, but the height difference must comply the stated
requirements.
* Try to reduce the bending of the piping line as much as possible so as to avoid possible negative impacts upon the
performances of the units.

Selection of installation positions for outdoor unit
*
* To install the outdoor unit at the places which can stand the load of the machine weight and will
not cause big vibrations and noises;
* To install the unit at the places not to be exposed to rain or direct sunshine, and the places with
good ventilation;
* The noises generated from the unit will not affect the neighboring places;
* Do not install the unit on non-metal frame;
* Not to install the unit at the places where there might occur the generation, inflow, stay or
leakage of inflammable gases;
* Pay attention to the drainage of the condensed water from the base plate during operations;
* To avoid the air outlet being directly against the wind.
Detailed space requirements around the outdoor unit
1. When there are obstacles above
the unit
2. When the front (air outlet) is open 3. When there are obstacles only in
the front (air outlet)
4. When there are obstacles at the front and rear sides.
5. When there are obstacles all around
the unit on four sides.
Although the top side is open, the
installation is not to be done if there
are obstacles all around.

INSTALLATION & REPAIR GUIDE
Split Wall-Mounted air conditioner
1.Installation of wall-mounting plate
Fix the wall-mounting plate firmly on the wall with screws.
Make sure of the leveling of the plate. Slanted wall-mounting
plate might jeopardize the smooth discharge of the condensed
water.
2.Drill holes on the wall
3.Installation of drain pipe
Install the pipelines of the indoor unit in accordance with
the direction of the wall holes. Wrap tightly the drain pipe
and the pipelines with tape. Make sure that the drain pipe
is underneath the pipelines. (Fig.3) (When the drain pipe
passes the room interior, some condensed water might
occur to its surfaces if the humidity is very high).
4.Installation of indoor unit
Pass the connection wires, connecting pipelines and drain
pipe through the wall hole. Hang the indoor unit on the
hooks at the top of the wall-mounting plate so that the
hooks at the bottom of the indoor unit match the hooks of
the wall-mounting plate. (Fig.4)

Drill holes at places slightly below the wall-mounting plate,
with hole diameter of 65mm(2-3/5") and the outer edge of
the hole 5-10mm(1/5-2/5") lower (Fig.2) so that the condensed
water can smoothly flow out. Cut the wall penetrating pipe
to proper length according to the thickness of the wall (35mm(1/10-1/5") longer than the wall thickness) and insert
the pipe as indicated in Fig.2.

Inspections:
a. Check if the hooks at the top and bottom
are firmly fixed.
b. Check if the position of the master unit is
properly leveled.
c. The drain pipe should not curve upward
(Fig.5).
d. The drain pipe should be at the lower part
of the wall pipes (Fig. 5).

* Try to ship the product to the installation location in its original package;
* As the gravity center of the unit is not at the installation center, special caution should be taken
when using hoisting cables to lift it up;
* During shipping, the outdoor unit must not be slanted to over 45 degrees (Do not store the unit
in a horizontal way).
* Use expansion bolts to fix the mounting supports on the wall;
* Use bolts and nuts to fix the outdoor unit firmly on the supports and keep on the same level;
* If the unit is installed on the wall or at the rooftop, the supports have to be firmly fixed so as to
resist earthquake or strong wind.

Ordinary pipelines connection
(it is suitable for non-quick coupler)
No dust ,foreign articles,air or moisture should be allowed to enter the air conditioning system.Careful
attention should be paid when pipeline connection for outdoor unit is made.Try to avoid repeated
curves as much as possible,otherwise hardening or cracks might be caused to the copper pipes.Suitable
wrenches should be used when the pipeline connection is done so as to ensure appropriate torque(refer
to following torque Table 1).Excessive torque might damage the joints while too little torque might
lead to leakage.

Soap water method
(1)
Remove the caps from the gas side and
liquid side valves.
(2)
Remove the service-port cap from the gas
side valve.
(3) To open the gas side valve turn the valve
stem counterclockwise approximately
90°,
wait for about 2-3 seconds, and close it.
(4)
Apply a soap water or a liquid neutral
detergent on the indoor unit connection or
outdoor unit connections by a soft brush to
check for leakage of the connecting points
of the piping.
(5)
If bubbles come out, the pipes have
leakage.
Evacuation
Outdoor
unit
Connect the charge hose end described in the
preceding steps to the vacuum pump to
evacuate the tubing and indoor unit.
Confirm the "Lo" knob of the manifold valve is
open. Then, run the vacuum pump.
The operation time for evacuation varies with
tubing length and capacity of the pump. The
following table shows the time required for
evacuation.
vacuum pump is used
When the desired vacuum is reached, close the
"Lo" knob of the manifold valve and stop the
vacuum pump.
Adding refrigerant
Refrigerant must be added if the piping measures more
than 7.5 metres(%") in length.This operation can only
be performed by a professional technician,for the
additional
amount,see the table 3 below.
