Installation Manual

7 REFRIGERANT PIPING

WARNING

•If the refrigerant gas leaks during installation, ventilate the room.

If the leaked refrigerant gas comes into contact with fire, noxious gas may be generated.

•After installation, check that the refrigerant gas does not leak.

If the refrigerant gas leaks into the room and comes into contact with fire such as a fan heater, stove, or kitchen range, noxious gas may be generated.

„Connection of refrigerant pipe

• The refrigerant pipe connecting section is set in the

 

outdoor unit. Remove the front panel and the piping/

Hook

wiring panel. (M5: 9 pcs.)

• As shown in the illustration on the right, the hooks are

 

at the right and left sides of the front panel. Lift up and

 

•Adding only one follower unit is possible. Install the additional unit so that its position is opposite to the header unit. Use an extension valve for installation (See the figure above.).

Specify the pipe diameter in advance to allow for adding another unit.

remove the front panel.

•

Pipes can be drawn out forward or downward from the

 

 

 

outdoor unit.

 

 

• When drawing out the pipe forward, draw it out to the

 

 

 

outside via the piping/wiring panel, and leave a space

 

0

 

of 500mm or more from the main pipe connecting the

5

 

 

 

outdoor unit with the indoor unit, considering service

 

 

 

work or other work on the unit. (For replacing the

 

 

 

compressor, 500mm or more space is required.)

 

 

•

When drawing out the pipe downward, remove the

 

 

 

knockouts on the base plate of the outdoor unit, draw

 

 

 

the pipes out of the outdoor unit, and perform piping on
