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.

 (PA12KKD, PA16KKD) flexible cords, type designation 245 IEC 57 

or heavier cord. The attached wire with two connectors should be applied. 

‹  Ensure the color of wires of outdoor unit and the terminal numbers are the same to the indoor’s 

respectively. 

‹  Earth lead wire shall be longer than the other lead wires as shown in the figure for the electrical safety 

in case of the slipping out of the cord from the anchorage.

1 

Please cut using pipe cutter and then remove the burrs. 

2 

Remove the burrs by using reamer. If burrs are 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.

•  After selecting the best location, start installation according to indoor/outdoor unit installation diagram. 

1 

Fix the unit on concrete or rigid frame firmly and horizontally by bolt nut (ø10 mm). 

2 

When installing at roof, please consider strong wind and earthquake. 
Please fasten the installation stand firmly with bolt or nails. 

 
 
 
 
 
 
 

Please make flare after inserting flare nut (locate at joint portion, of tube assembly) onto the copper pipe. (In case of 
using long piping) 
 Connect the piping 
•  Align the center of piping and sufficiently tighten the flare nut with fingers. 

•   Further tighten the flare nut with torque wrench in specified torque as stated in the table. 

Decide piping length and then cut by using pipe cutter. Remove burrs from cut edge. Make flare after inserting the 
flare nut (locate at valve) onto the copper pipe. Align center of piping to valves and then tighten with torque wrench to 
the specified torque as stated in the table.
