INSTRUCTION MANUAL
WARNING!
Read and follow all safety precautions in
Instruction Manual - improper use can cause
serious injury.

USER NOTICES
☆When operating, the total capacity of the cooperating indoor unit should be no more than that of
outdoor unit. Otherwise, it will cause the shortage of cooling (heating) capacity.
☆Install a circuit breaker (or fuse) to each indoor unit according to capacity of the unit and a master
circuit breaker to all indoor units. Each of the circuit breaker, which are normally on, is used for
short circuit and abnormal overload protection of indoor unit. The master circuit breaker is used
to supply or cut off power of all indoor units together. The general power supply of all indoor units
must be cut off before cleaning them.
☆In order to start the unit successfully, the general power supply switch of the air-conditioning units
should be turned to the “ON” position for 8 hours before running.
☆After each of indoor units received the stop running signal, the fan motor of the indoor unit will use
the surplus cool or surplus heat of the heat exchanger go on running for 20-70 seconds, this is the
preparation for the next time use and this is the normal phenomenon.
☆When the selected mode of the indoor unit conict with the mode of outdoor unit, after 5 seconds,
the remote control will display the operation conict, the indoor unit will stop running, then to unify
the running modes of the indoor unit and outdoor unit, the unit will get right. There is no conict in
the COOL mode and DRY mode, the FAN mode will not conict with any other modes.

1 Safety Information
Please read this manual carefully before use this unit, and operate it correctly according to the
guide in this manual.
Please take specially note to the meaning of these two marks.
Warning : This mark means that it may cause casualty or badly hurt if the operation is incorrect.
Note : This mark means that it may cause casualty or property loss if the operation is incorrect.
Warning!
●Do not adopt fuse with unsuitable capacity or adopt iron thread instead of fuse, otherwise
malfunction or re may happened.
●Turn the main power off immediately if malfunction (such as smell the burning odor etc.) happened.
●Maintain ventilation to prevent oxygen leakage in room.
● Don’t insert nger or stick like things into discharge vent or outlet grill.
●Please make sure the unit is installed in the place that can withstand the weight of it adequately. If
the place is not strong enough, the air conditioner may drop and cause casualty event.
●Don’t spray or smear any oil paint or insecticide on the surface of unit, otherwise, fire may be
caused.
● Do not ret the air conditioner. Please contact the agency or professionals to repair or remove the
conditioner.
Note!
●Please check and make sure the cord, drainage pipe and tubes are connected in the correct way
to avoid leakage of water and refrigerant, electric shock or re, etc..
●The main power must be reliably earthed in order to assure the air conditioner is effectively
earthed and avoid electric shock. Please don’t connect the earthing line with the gas pipe, water
pipe, lightening rod or the connecting line of telephone.
● The air conditioner should be started at least after running for 5 min; otherwise it would affect the
duration of the unit.
●Don’t let the children operate the air conditioner.
●Please don’t operate the unit by wet hand.
● Please turn off the main power of the unit before cleaning the conditioner or replace the lter.
●Please turn off the main power if the air conditioner will not be used for a long time.

4.2 Selection of the installation location for indoor unit
●Obstruct should be away from the air intake or outlet vent of the indoor unit so that the
airow blow all over the place of the room.
●Make sure the installation of the indoor unit accords with the requirement for installation
dimension drawing.
●Select the place which can withstand 4 times weight of the indoor unit and would not
increase the operating noise and shake.
●The installation place should be horizontal.
●Select the place, where coagulated water is easy to discharge and outside unit to be
connected.
●Above 18000mm between the earth and indoor unit should be ensured for maintenance and
repair.
●Use hoisting screw to check if the installation place can withstand 4 times weight of the units
and strengthen it before installing.

4.4 Hoisting the main body of the unit
1) Hoisting the main body
Attach the hoisting stand base to hoisting screw. In order to rm the hoisting stand base, use nuts
with washers on either end of it.(refer to Fig. 1)
2) Please refer to the dimension of ceiling opening on the cardboard for installation
● There is a mark for ceiling opening center on the cardboard.
● There is also a mark for main body center on the cardboard.
● Use screws to x the installation cardboard on the unit. (refer to Fig.3)
3) Adjust the unit to right installation place.
4) Check if the unit is horizontal.
Inner drainage pump and bobber switch are installed in indoor unit. Check if every side of the unit
is horizontal by water lever. (If the unit slants to opposite direction towards which coagulate water
ows, it will bring malfunction to the bobber switch and cause water drops. (refer to Fig.2)
5) Unscrew the screws on the cardboard, which can be used for installing front panel.
4.5 Drainage pipe
1) Install the drain hose
● The diameter of the drain hose should be equal or bigger than the connection pipe’s. ( The
diameter of polythene pipe: Outer diameter 25mm Surface thickness ≥1.5mm)
● Drain hose should be short and drooping gradient should at less 1/100 to prevent the formation
of air bubble.
● If drain hose cannot has enough drooping gradient, drain raising pipe should be added.
● To prevent bent of the drain hose, the distance between hoisting stand should is 1 to 1.5m.
×
(wrong)
(Correct) 1/100 or more gradient
1-1.5m
● Use the drain hose and clamp attached. Insert the drain hose to the drain vent, and then tighten
the clamp.
● Entwine the big sponge on the clamp of drain hose to insulate heat.
● Heat insulation should be done to indoor drain hose.
2) Drain stepup pipe note
● The install height of the drain raising pipe should less than 280mm.
