The center of installation plate should be at more than 1 at right and left of the wall. 
The distance from installation plate edge to ceiling should more than 2. 
From installation plate left edge to unit’s left side is 3. 
From installation plate right edge to unit’s right is 4.

: For left side piping, piping connection for liquid should be about 5 from this line. 

 

: For left side piping, piping connection for gas should be about 6 from this line. 

1  Mount the installation plate on the wall with 5 screws or more (at least 5 screws). 

(If mounting the unit on the concrete wall, consider using anchor bolts.) 

o  Always mount the installation plate horizontally by aligning the marking-off line with the thread and using 

a level gauge. 

2  Drill the piping plate hole with ø70 mm hole-core drill. 

o 

Line according to the left and right side of the installation plate. The meeting point of the extended line is 
the center of the hole. Another method is by putting measuring tape at position as shown in the diagram 
above. The hole center is obtained by measuring the distance namely 128 mm for left and right hole 
respectively. 

o 

Drill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoor 
side. 

 

1  Insert the piping sleeve to the hole. 
2  Fix the bushing to the sleeve. 
3  Cut the sleeve until it extrudes about 15 mm 

from the wall. 

 

   

           

   When the wall is hollow, please be sure to use 

the sleeve for tube assembly to prevent dangers 
caused by mice biting the connection cable. 

 

4  Finish by sealing the sleeve with putty or 

caulking compound at the final stage.

designation 245 IEC 57 or heavier cord. 

3  Bind all the indoor and outdoor connection 

cable with tape and route the connection cable 
via the escapement. 

4  Remove the tapes and connect the connection 

cable between indoor unit and outdoor unit 
according to the diagram below. 

 

 

 
Note: 
  Secure the connection cable onto the control board with the holder. 

  Ensure the colour of wires of outdoor unit and the terminal Nos. are the same to the indoor’s respectively. 

  Earth wire shall be Yellow/Green (Y/G) in colour and longer than other AC wires for safety reason.

1  Please cut using pipe cutter and then remove the burrs. 
2  Remove the burrs by using reamer. If burrs is not removed, gas leakage may be caused. 

Turn the piping end down to avoid the metal powder entering the pipe. 

3  Please make flare after inserting the flare nut onto the copper pipes.
