  If an awning is built over the unit to prevent direct 

sunlight or rain, be careful that heat radiation from 
the condenser is not obstructed. 

  There should not be any animal or plant which 

could be affected by hot air discharged. 

  Keep the spaces indicated by arrows from wall, 

ceiling, fence or other obstacles. 

  Do not place any obstacles which may cause a

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 center to unit’s left side is 3. 
From installation plate center to unit’s right side 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. 

31 

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.

How to keep the cover

In case of the cover is cut, keep the cover at the rear 
of chassis as shown in the illustration for future 
reinstallation.
(Left, right and 2 bottom covers for piping.)

Install the indoor unit

Hook the indoor unit onto the upper 
portion of installation plate. (Engage 
the indoor unit with the upper edge 
of the installation plate). Ensure the 
hooks are properly seated on the 
installation plate by moving it in left 
and right.
