The dimensional relationship between H, L and A is as
shown in the table below.
0 < L ≤ 1/2H
L ≤ H
1/2H < L ≤ H
H < L
Install the frame to achieve "L ≤ H".
NOTE
1.
Close the area under the frame so that the outlet air does
not bypass there.
2.
Only two outdoor units can be installed side by side.
(D) When outdoor units are stacked
(1)
When an obstruction is present on the air outlet
side
NOTE
1.
Only two outdoor units can be stacked.
2.
About 4 in. is required as the drain piping size for the upper
outdoor unit.
3.
Close the area Z (gap between the upper outdoor unit and
the lower outdoor unit) so that the outlet air does not by-
pass there.
(2)
When an obstruction is present on the air inlet side

CAUTIONS ON INSTALLATION
•
Before installation, confi rm the strength and levelness of the
foundation so that vibrations and noise are not generated.
•
Fix the outdoor unit securely on a rigid base with foundation
bolts as shown in the foundation drawing below.
(Prepare 4 sets of commercially available M12-type or
equivalent foundation bolts, nuts and washers.)
•
Use resin washers to prevent the paint from being scratched
off and rusting.
•
The foundation bolts should be protruded by 15/16 in.

〈〈Drain treatment〉〉
•
In a location where drain from the outdoor unit may cause
troubles (for example, where drainage may splash on gen-
eral passersby), perform the drain piping work using the
drain plug (optional).
