NSTALLATION SERVICING SPACE
The connection piping outlet direction in the installation shown in
figure 4 is frontward or downward. The unit of numeric values is
mm.
When routing the piping backward, secure space of ≥250 mm on
the right side of the unit.

1
In these cases, close the
bottom of the installation
frame to prevent the
discharged air from
being bypassed
2
In these cases, only 2
units can be installed.
3
In these cases, no
restriction of height L1.
This situation is not
allowed
(B) In case of stacked installation
1.
In case obstacles exist in front of the outlet side.
2.
In case obstacles exist in front of the air inlet.
NOTE
Do not stack more than one unit.
About 100 mm is required as the dimension
for laying the upper outdoor unit's drain pipe.
Get the portion A sealed so that air from the
outlet does not bypass.
(C) In case of multiple-row installation (for roof top use, etc.)
1.
In case of installing one unit per row.
≥1000
2.
In case of installing multiple units (2 units or more) in lateral
connection per row.
