*1: Minimum 350 mm is required for 90° bends in refrigerant piping.

*2:   is “Min. 200 mm” <recommendation>.

In the case of less than 

00 mm (for example   is 100 mm), the exchange work 

of Branch box from a maintenance hole becomes difficult (Only exchange work 

of a PCB, linear expansion valve coils and sensors are possible).

In the case of “   450 mm”, prepare a maintenance hole at a PCB side (as it is 

shown in Fig. 4-8), and “Min. 300 mm” is needed as distance  .

In the case of less than 300 mm (for example   is 100 mm), the exchange work 

of Branch box, linear expansion valve coils and sensors from a maintenance 

hole becomes difficult (Only exchange work of a PCB is possible .

. The space when installing on the floor. (Fig. 4-10

3

.  The space when installing on a wall. (Fig. 4-11)  

The installation direction is limited when installing on a wall. (Fig. 4-1)

 

When installing the unit on the wall, install the piping connected to the outdoor 
unit facing down.  Other ways are not acceptable.

*3:   is “   600 mm” <recommendation>.

5. Refrigerant piping

*  Always follow the specifications written in the installation manual of the outdoor unit. Exceeding these requirements may cause  reduced performance of the equipment, 

and malfunctions.
