NOTE
• Equalizer pipe is only for connection between outside units on multi
outside unit system.
That is not connect to indoor units.
• Make sure the onsite piping does not come into contact with other
piping or the bottom frame or side panels of the unit.

Precautions when connecting piping between outside units
The Outside unit multi connection piping kit (sold separately) is
needed to connect piping between outside units in multi system.
Only proceed with piping work after considering the limitations on
installation listed here and in “5. Branching the refrigerant pip-
ing”, always referring to the kit’s installation manual.
(1) About outside unit multi connection piping kit
• Install the joint horizontally so that the attached warning label
faces strait up, and the tilt is within ±15°. (Refer to figure 13-1)
Do not install vertically. (Refer to figure 13-2)
• Maintain a straight portion of 19-5/8 in. or more until the split of
the joint without wrapping any onsite piping around this area.
Over 19-5/8 in. of straight area can be maintained by connect-
ing at least 4-3/4 in. of onsite pipe (straight) to the joint.
(Refer to figure 13-3)
(Refer to figure 13)
1. Warning label
2. Horizontal surface
3. ±15° or less
4. Ground
5. Onsite pipe (4-3/4 in. length or more)
6. Straight part of 19-5/8 in. or more
7. C-arrow view
8. D-arrow view
(2) The piping between outside units must be installed level (Pattern
1) or with a rise (Pattern 2). Otherwise oil may pool in the pipes.
(3) To avoid the risk of oil detention in the stopping unit, always con-
nect the shutoff valve and the piping between outside units as
shown A or B in the figure below.
