•  There should not be any heat source or steam near the unit.  

•  There should not be any obstacles blocking the air 

circulation. 

•  A place where air circulation in the room is good. 

•  A place where drainage can be easily done. 

•  A place where noise prevention is taken into consideration. 

•  Do not install the unit near the door way.  

•  Ensure the spaces indicated by arrows from the wall, ceiling, 

fence or other obstacles. 

•  Recommended installation height for indoor unit shall be at 

least 2.5m. 

•  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 short circuit 

of the discharged air. 

•  If piping length is over the rated length, additional refrigerant 

should be added as shown in the table below: 

 

 
 
 

 
Example: For PC12KKD 
If the unit is installed at a 10m distance, the quantity  
of additional refrigerant should be 60 g. 
…… (10-7) m x 20g/m = 60 g

The mounting wall is strong and solid enough to prevent if from the vibration. 
 
The centre of installation plate should be at more 
than 450 mm at right and left of the wall. 
 
The distance from installation plate edge to 
ceiling should more than 75mm. 
 
From installation plate left edge to unit’s left side 
is 62 mm. 
 
From installation plate right edge to unit’s right 
side is 79 mm. 
 

○

B  

: For left side piping, piping connection for gas should be about 45 mm from this line. 

 

: For left side piping, piping connection cable should be about 785 mm from this line. 

 

1  Mount the installation plate on the wall with 5 screws or more. (If mounting the unit on the wall, consider 

using anchor bolts.) 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. 

z  Put measuring tape at position as shown in the diagram above. The hole centre is 

obtained by measuring the distance namely 115 mm and 120 mm for left and right hole 
respectively. 

z  Drill the piping plate hole at either the right or left and the hole should be slightly slanted 

to the outdoor side. 

 

1 

Insert the piping sleeve to the hole. 

2 

Fix the busing to the sleeve. 

3 

Cut the sleeve until it extrudes about 15mm from the wall  
 

 

 

4 

Finish by sealing the sleeve with putty or caulking compound at the final 
stage.  

 
 

When the wall is hollow, please be sure to use the sleeve for tube 
ass’y to prevent dangers caused by mice biting the connecting 
cable.
