Selection of installation positions fo r outdoor unit
*
*To install the outdoor unit at the places which c an st and the load of the machine weight and will
not cause big vibrations and noises;
*To install the unit at the places not to be expos ed to rain or direc t sunshine, and the places with
good v entilation;
* The noises generated from the unit will not affect the neighboring plac es ;
*Do not install the unit on non-metal fram e;
*Not to install the unit at the places w here there might occur the generation, inflow, stay or
leakage of inflam m able gas es ;
*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.

*, a groov e
for the pipes has to be opened at the proper place on
the bas e stand.
1.Installation of wall-m ounting plate
Fix the wall-m ounting plate firmly on the wall with scr ews.
Make sur e of the leveling of the plate. Slanted wall-m ounting
plate might jeopardize the s m ooth disc harge of the c ondens ed
water.
2.Drill holes on the wall
Drill holes at places slightly below the wall-m ounting plate,
with hole diam eter of 65mm(2-3/5") and the outer edge of
the hole 5-10mm(1/5-2/5") low er (Fig.2) so that the condensed
water can sm oothly flow out. Cut the wall penetrating pipe
to proper length accor ding 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.
3.Installation of drain pipe
Ins tall the pipelines of the indoor unit in accor danc e with
the direction of the wall holes. Wrap tightly the drain pipe
and the pipelines with tape. Make sur e that the drain pipe
is underneath the pipelines. (Fig.3) (W hen the drain pipe
passes the room interior, som e c ondens ed water might
occur to its sur faces if the hum idity is ver y high).

pipe through the wall hole. Hang the indoor unit on the
hooks at the top of the wall-m ounting plate so that the
hooks at the bottom of the indoor unit match the hooks of
the wall-m ounting plate. (Fig.4)

Ordinary pipelines connection (it is suitable for non-quick coupler)
No dust ,foreign articles,air or moisture s hould be allow ed to enter the air conditioning system .Careful
attention should be paid when pipeline connection for outdoor unit is m ade.Try t
cur ves as much as possi ble,otherwise hardening or cr acks might be caused to the copper pipes.Suitable
wrenches should be used w hen the pipeline connection is done so as to ensure appr opriate torque(refer
to follow ing torque Table 1).Excessive torque might
lead to leakage.

and the follow ing pipeline connec tion procedures should
be adopted:

2.Align the joint counter of c onnec ting pipe with the proper
indoor and outdoor joint c onic sur faces,tighten the connecting
nut m anually.Then,make it secur e with a wrench as shown

3.Remove the two valve cor e c aps from the outdoor unit.
4.Turn on the high and low pressur e valve cor es with an
socket wrench,then tighten the two valve cor e caps of the

1.C heck that pipelines connec tion have been properly
connec ted,rem ove the charging port cap,and connect
the m anifold gauge and the vacuum pum p to the
charging valve by ser vice hoses as s hown Fig.8.
2.O pen the valve of the low pressur e side of m anifold

ndoor
unit and the c onnec ting pipes until the pressur e in
them low ers to below 1.5mmHG(The operation time
for vacuum ing is about 10 minutes ).W hen the desired
vacuum is reached,close the valve of the low pressur e
of the m anifold and stop the vacuum pum p.
3.Disconnec t the ser vice hos es and fit the cap to
the c harging valve.
4.Remove the blank caps ,and fully open the spindles
of the 2-way and 3-w ays valves with a service valve
wrench.
5.Tighten the blank caps of the 2-way and 3-w ays
valves,applying the above torque Table 1.

After the pipieline c onnec tion is done,use a leakage inspection device or soap s uds to car efully check
if there is any leakage at the joints.This is an im porant step to ensure the quality of ins tallation.Once
a leakage is detected,proper t
reatm ent should be taken im m ediately.

Finishing touches
*Use thermal tube to wrap the joints and wrap the tube tightly with ethy lene tapes.
*Fix the wrapped pipelines on the exterior wall with clam ps.
*Fill in the gaps left over by the pipeline hole and wall hole to prevent rain-water from entering.
*
Test running
* Connect to the pow er source, check if the function selection keys on the rem ote controller are
working properly.
* C heck if the room tem perature adjustm ents and timer settings are working properly.
* C heck if the drain is sm ooth.
* C heck if there is any abnormal noise or vibration during operation.
* C heck if there is leakage of refrigerant.

Suitable Installation Position
*
Isn't there anything which prev ents ventilation or obstructs operation in front of the indoor unit ?
Do not install the unit following plac e .

Inspection and Maintenance
*
Accor ding to the ser vice conditions and operating environm ent , the inside of the air conditioner
will bec om e dirty after sever al seas ons (3 to 5years ) of ser vice , resulting in decreased operating
perform ance .Inspec tion and maintenance are recom m ended in addition to us ual cleaning (The
air conditioner can be used for a longer period and without anxiety .)
