Fitting of the Mounting Plate and Positioning of the wall Hole
Fixing the indoor unit body
When the mounting plate is first fixed
1. Carry out, based on the neighboring pillars or lintels, a proper leveling for the plate
to be fixed against the wall, then temporarily fasten the plate with one steel nail.
2. Make sure once more the proper level of the plate, by hanging a thread with a
weight from the central top of the plate, then fasten securely the plate with the
attachment steel nail.
3. Find the wall hole location A using a measuring tape
●
Hang surely the unit body onto the upper notches of the
mounting plate. Move the body from side to side to verify its
secure fixing.
●
In order to fix the body onto the mounting plate,hold up
the body aslant from the underside and then put it down
perpendicularly.
Unloading of indoor unit body

● Fix to side bar and lintel a mounting bar, Which is separately sold, and then
fasten the plate to the fixed mounting bar.
●
Remove terminal cover at right bottom corner of indoor unit, then take
off wiring cover by removing its screws.
● Refer to the previous article, “ When the mounting plate is first fixed “, for the
position of wall hole.

When connecting the cable after installing the indoor unit
Making a Hole on the Wall and Fitting the Piping Hole Cover
● Make a hole of 60 mm in diameter, slightly descending to outside the wall.
● Install piping hole cover and seal it off with putty after installation
Wall hole
1. Insert from outside the room cable into left side of the wall
hole, in which the pipe has already existed.
2. Pull out the cable on the front side, and connect the cable
making a loop.

Drawing of pipe
Insert the cable from the back side of the unit, then pull it out on the front side.
Loosen the screws and insert the cable ends fully into terminal block, then
tighten the screws.
Pull the cable slightly to make sure the cables have been properly inserted and
tightened.
After the cable connection, never fail to fasten the connected cable with the
wiring cover.
[ Rear piping ]
● Draw pipes and the drain hose, then fasten them with the adhesive tape
[ Left· Left-rear piping ]
● In case of left side piping, cut away, with a nipper, the lid for left piping.
● In case of left-rear piping, bend the pipes according to the piping direction to
the mark of hole for left-rear piping which is marked on heat insulation materials.
Note
When connecting the cable, confirm the terminal number of indoor and
outdoor units carefully. If wiring is not correct, proper operation can not
be carried out and will cause defect.

Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.
The standard pipe length is 5m. If it is overm, the function of the unit will be
affected. If the pipe has to be lengthened, the refrigerant should be charged,
according to 20 g/m. But the charge of refrigerant must be conducted by professional air conditioner engineer. Before adding additional refrigerant, perform air
purging from the refrigerant pipes and indoor unit using a vacuum pump,then
charge additional refrigerant.

3. The wiring method should be in line with the local wiring standard.
4. After installation, the power plug should be easily reached.
5. A breaker should be incorporated into fixed wiring. The breaker should be
all-pole switch and the distance between its two contacts should be not less
than 3mm.
3. Vacuumize for over 15min.And check the level gauge which should read -0.1MPa
(76 cm Hg) at Iow pressure side. After the completion of vacuumizing, close the

CAUTION
ƽ If the refrigerant of the air conditioner leaks, it is necessary to discharge all the
refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.
ƽ Please do not let other cooling medium, except specified one (R410A), or air
enter into the cooling circulation system. Otherwise, there will be abnormal
high pressure in the system to make it crack and lead to personal injuries.
Power Source Installation
ƽ The power source must be exclusively used for air conditioner. (Over I0A)
ƽ In the case of installing an air conditioner in a moist place, please install an earth leakage breaker.
ƽ For installation in other places, use a circuit breaker as far as possible.
