1.Fitting of the Mounting Plate and Positioning of the wall Hole  
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  
A=170mm  
Fit the level line  
When the mounting plate is fixed side bar and lintel  
Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten  
the plate to the fixed mounting bar.  
Refer to the previous article, " When the mounting plate is first fixed ", for the  
position of wall hole.  
2.Making a Hole on the Wall and Fitting the Piping Hole Cover  
Make a hole of 70 mm in diameter,  
slightly descending to outside the wall.  
Install piping hole cover and seal it  
off with putty after installation

3.Installation of the Indoor Unit  
Drawing of pipe  
[ 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.

Indoor unit  
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

Fix with adhesive tape  
Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.  
[Other direction piping]  
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.  
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.

Indoor unit  
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 H05/07RN-F or 245IEC57(YZW).  
2. If the fuse on PC board is broken please change it with the type of T. 3.15A/250V.  
3. The wiring method should be in line with the local wiring standard.  
4. After installation, the power plug should be easily reached.

2.Connection of pipes  
To bend a pipe, give the roundness as large as possible not to crush the pipe ,and the bending radius  
should be 30 to 40 mm or longer.  
Connecting the pipe of gas side first makes working easier.  
The max vertical distance between the indoor unit and the outdoor unit is 5 m.  
Forced fastening without careful centering  
may damage the threads and cause a  
leakage of gas.
