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

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 wi  
is not correct, proper operation can not be carried out and will cause defect.

1.Connection of pipes  
To bend a pipe, give the roundness as large as possible not to crush the pipe  
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.
