4.3. Dimensions and 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.
(A) In case of non-stacked installation (See figure 4)

(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.

4.4. Inspecting, handling and unpacking the unit
Handling the unit
As shown in the figure, bring the unit slowly by grabbing the left and
right grips.
Place your hands on the corner instead of holding the suction inlet in
the side of the casing, otherwise the casing could be deformed.
Take care not to let hands or objects come in contact with
rear fins.
Installation method for prevention of falling over
If it is necessary to prevent the unit from falling over, install as shown
in the figure.
■
