Name Installation Box Base Plate Screw M4X25 Front Panel Screw ST2.2X6.5
Fig.4 presents simply how to install the wired controller and please pay special attention to the following
instructions.
(1) Please cut off the power supply for all buried power cords in the installation hole and the whole
installation must be done without any live part.
(2) Pull out the four-core twisted pairs in the installation hole and let it go through the rectangular hole on the
base plate of the wired controller.
(3) Fix the base plate on the wall with screws M4X25. (4) Let the four-core twisted pairs go through the slot of the wired control and then x the front panel and
base plate together.
(5) Fasten the front panel and base plate with screws ST2.2X6.5.
NOTE
Pay special attention to the electric wiring to prevent that the air conditioner goes out of control owing to the
electromagnetic interference.
① 
The signal line and communication line should be separated with the power cord and the connecting wires
between indoor and outdoor units should be with a minimal distance of 20cm, otherwise the communication
would go wrong.
② 
If the air conditioner is installed where it would be affected by electromagnetic interference, the signal line
and the communication line must be the shielded twisted pairs.

3 INSTALL THE UNIT
3�1 Install the rear panel
(1) Always mount the rear panel horizontally.
Due to the water tray of indoor unit has been
adopted the both-way drainage design, the outlet
of water tray should be adjusted slightly down when installing, that is taking the outlet of the water tray as the center of a circle, the included angle between the evaporator and level should be 0 or more, that is good for condensing water drainage.
(2) Fix the rear panel on the wall with screws.
(Where is pre-covered with plastic granula )
(3) Be sure that the rear panel has been xed rmly enough to withstand the weight of an adult of 60kg,
further more, the weight should be evenly shared by each screw.
3�2 Install the piping hole
① 
Ake the piping hole (Ф55) in the wall at a slight downward slant to the
outdoor side.
② 
Insert the piping-hole sleeve into the hole to prevent the connection piping
and wiring from being damaged when passing through the hole.
3�3 Install the water drainage pipe
(1) For well draining, the drain hose should be placed at a downward slant. (2) Do not wrench or bend the drain hose or ood its end by water.(As
show in Fig.6)
(3) When the long drainage hose passing through indoor, should wrap
the insulation materials.
Note:
When connecting the electric wire if the wire length is not enough, please contact with the authorized service shop to buy a exclusive electric wire that is long enough and the joint on the wire are not allowed.
● The electric wiring must be correctly connected, wrong connection
may cause spare parts malfunction.
● Tighten the terminal screw in order to prevent loose.
● After tighten the screw, slight pull the wire and conrm
whether is it rm or not.
● If the earth wire is wrong connection, that may cause
electric shock.
● The cover plate must be fixed, and tighten the connection wire, if it is poor installed, that the dust, moisture may enter in or the connection terminal will be affected by outside force, and will cause re or electric shock.
3�4 Install the unit
● The piping can be lead out from right, right rear, left ,left
rear.
(1) When routing the piping and wiring from the left or
right side of indoor unit, cut off the tailings from the chassis
in necessary(Show in Fig.7)
1) Cut off the tailings 1 when routing the wiring only;
2) Cut off the tailings 1 and tailings 2 when routing both
the wiring and piping.
(2) Take out the piping from body case, wrap the piping electric wire, water pipe with tape and pull them through the piping hole (As show in Fig.8)
(3) Hang the mounting slots of the unit on the upper tabs
of the rear panel and check if it is rm enough.(As show in
Fig.9)
(4) The height of the installed location should be 2.5 m or more from the oor.

MAINTENANCE
1 TROUBLESHOOTING
1�1 CAUTION
Don’t attempt to repair the air conditioner by yourself. It can cause an electric shock or re. Please check the following items before asking for repair, it can save your time and money.
Phenomenon Troubleshooting
Not operate immediately when the air conditioner is restarted.
Once the air conditioner is stopped, it will not operate in approximately 3minutes to protect itself
There's unusual smell blowing from the outlet after operation is started.
The unit has no peculiar smell by itself. If has, that is due to the smell accumulated in the
ambient.
Solution method: Cleaning the lter. If problem still has, so need to clean air conditioner. (Please
contact with the authorized maintenance center.)
Sound of water ow can be
heard during the operation.
The sound is due to water owing they are not malfunctions.
In COOL mode, sometimes the mist
emitted from the air outlet vent.
When the indoor temperature and humidity are very high, this phenomenon would happen. This is caused by the room air is swiftly cooled down. After running for a while, indoor temperature and humidity will fall down, the mist will die away.
Creaking noise can be heard when start or stop the unit.
This is caused by the deformation of plastic due to the changes of temperature.
The unit can not run.
Has the power been shut down? Is power plug loosed? Is the circuit protection device tripped off or not? Is voltage higher or lower? (Tested by professionals) Is the TIMER correctly used?
Cooling(Heating) efciency
is not good.
Is Temp setting suitable? Were inlet and outlet vents obstructed? Is lter dirty? Are the windows and doors clothed? Did Fan speed set at low speed? Is there any heat sources in the room?
Wireless remote control
is not available.
The unit is interfered by abnormal or frequent functions switchover occasionally the controller cannot operate. At this time, you need to pull out of the plug, and reinsert it. Is it in its receiving range? Or obstructed? To check the voltage in wireless remote control inside
is charged, otherwise to replace the batteries. Whether the wireless remote control is damaged.
If water leakage in the room.
The air humidity is on the high side.
Condensing water over owed. The connection position of indoor unit drainage pipe is loosed.
Indoor unit cannot deliver air.
In HEAT mode, when the temperature of indoor heat exchanger is very low, that will stop deliver air in order to prevent cool air. (Within 2min) In COOL mode, when the temperature of indoor heat exchanger is very high, that will stop deliver air in order to prevent heat air. (Within 2min)
Moisture on air outlet vent.
If unit is running under the high humidity for a long time, the moisture will be condensed on the air outlet grill and drip off.
Cooling LED blinks, display F0.
F0:Ambient temperature sensor is open or short-circuit.
Please cut off power at rst and then check whether the wires of ambient temperature sensor have been disconnected with the main board. If there are disconnected, please insert the ambient temperature sensor and then check whether it can run normally after power on. If it still can’t run normally; please replace the ambient temperature sensor.
