NOTE When connecting the piping on site, be sure to
use the accessory piping.
Make sure the onsite piping does not come into
contact with other piping, the bottom frame or side
panels of the unit.
4 Branching the refrigerant piping
For installation of the refrigerant branching kit, refer to the
installation manual delivered with the kit.
(See figure 14)
1 Horizontal surface
Follow the conditions listed below:
- Mount the refnet joint so that it branches either
horizontally or vertically.
- Mount the refnet header so that it branches horizontally.
Installation of the multi connection piping kit
(See figure 18)
- Install the joints horizontally, so that the caution label (1)
attached to the joint comes to the top.
Do not tilt the joint more than 15° (see view A).
Do not install the joint vertically (see view B).
- Make sure that the total length of the piping connected to
the joint is absolute straight for more than 500 mm. Only
if a straight field piping of more than 120 mm is
connected, more than 500 mm of straight section can be
ensured.
- Improper installation may lead to malfunction of the
outdoor unit.
5 Piping length restrictions
Make sure to perform the piping installation within the range of
the maximum allowable pipe length, allowable level difference
and allowable length after
"6.6. Example of connection" on page 7.

Regardless of the period
- Great caution is needed when passing copper tubes through
walls.
- Block all gaps in the holes for passing out piping and wiring
using sealing material (field supply). (The capacity of the unit
will drop and small animals may enter the machine.)
