sufficiently ventilated.
Place, possible to bear the unit, where vibration and noise are
not increased.
Place, where discharged wind and noise do not cause a
nuisance to the neighbors.
Place, where a distance marked is available as illustrated
in the above figure.
Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate.
Install an exclusive branch circuit of the power.
A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it.
To this unit, both liquid and gas pipes shall be insulated
as they become Iow temperature in operation.

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
Refer to the previous article, " When the mounting plate is first fixed ", for the
position of wall hole.
Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten
the plate to the fixed mounting bar.

1. Insert the drain hose into the dent of heat insulation materials of indoor unit.
2. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then
connect them.
3. Coat the flaring seal face with refrigerant oil and connect pipes.
Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape
4
Other direction piping
Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.
Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according
to the position of wall hole. When bending, be careful not to crash pipes.
Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation
of connecting part specially.
Fixing the indoor unit body
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.
4.Connecting the indoor/outdoor Electric Cable
Removing the wiring cover
Remove terminal cover at right bottom corner of indoor unit, then
take off wiring cover by removing its screws.

When connecting the cable after installing the indoor unit
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.
When connecting the cable before installing the indoor unit
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 .

is not correct, proper operation can not be carried out and will cause defect.
1. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar
qualified person.The type of connecting wire is H05RN-F or H07RN-F.
2. If the fuse on PC board is broken please change it with the type of T. 3.15A/250 V.
3. The wi ring method should be in line with the local wiring standard.
4. After installation, the power plug should be easily reached.

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.Connection
Use the same method on indoor unit. Loosen
the screws on terminal block and insert the
plugs fully into terminal block, then tighten the
screws.
Insert the cable according to terminal number
in the same manner as the indoor unit.
If wiring is not correct, proper operation can
not be carried out and controller may be
damaged.
Fix the cable with a clamp.
