š  Do not install the unit in excessive oil fume area 

such as kitchen, workshop and etc. 

š  There should not be any heat source or steam 

near the unit. 

š  There should not be any obstacles blocking the air 

circulation. 

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

š  A place where drainage can be easily done. 

š  A place where noise prevention is taken into 

consideration. 

š  Do not install the unit near the door way. 

š  Ensure the spaces indicated by arrows from the 

wall, ceiling, fence or other obstacles. 

š  Recommended installation height for indoor unit 

shall be at least 2.5 m. 

š  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. 

š  There should not be any animal or plant which 

could be affected by hot air discharged. 

š  Keep the spaces indicated by arrows from wall, 

ceiling, fence or other obstacles. 

š  Do not place any obstacles which may cause a 

short circuit of the discharged air. 

š  If piping length is over the [piping length for 

additional gas], additional refrigerant should be 
added as shown in the table.

Example: For E9*** 
If the unit is installed at 10 m distance, the quantity of 
additional refrigerant should be 50 g .... (10-7.5) m x 
20 g/m = 50 g.

The mounting wall shall be strong and solid enough to 
prevent it from the vibration. 
 

 

 
The center of installation plate should be at more than 
c

 at right and left of the wall. 

The distance from installation plate edge to ceiling 
should more than d. 
From installation plate left edge to unit’s left side is e. 
From installation plate right edge to unit’s right side is 
f

. 

 

○

B  

: For left side piping, piping connection for 

               liquid should be about g from this line. 
 

: For left side piping, piping connection for gas 

               should be about h 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. 

 

 

 
4  Finish by sealing the sleeve with putty or 

caulking compound at the final stage.

(This can be used for left rear piping and bottom 
piping also.)

1  The inside and outside connection cable can 

be connected without removing the front grille. 

2  Connection cable between indoor unit and 

outdoor unit shall be approved 
polychloroprene sheathed 4 x 1.5 mm

2

 flexible 

cord, type 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. 

 

 

 

 

 

 
 
 

 

o

 

Secure the connection cable onto the control board with the holder. 

o

 

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

o

 

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