Outdoor Unit Installation
If using a multi system, install as described in the
installation manual supplied with the outdoor unit.
Step 3-1 Mounting the outdoor unit
To promote proper condensate draining, the recommended
installation of the outdoor unit is elevated above the ground
on a mounting bracket attached to a concrete pad.
In areas where snowfall occurs, the unit must be mounted
above the snow line to allow for proper heating. Snow cannot
be allowed to collect on top of the unit. For promoting natural
drainage in a heavy snow fall area:
•
Make space more 80 mm between the bottom of the
outdoor unit and the ground for installation. (Ensure
that the drained water runs off correctly and safely.)
•
Allow enough separation distance between the product
and the ground.

1
Place the outdoor unit in the selected installation location
(Step 1-1 on page 7), ensuring proper clearances and with
the arrow on top of the unit pointing away from the wall.
2
Clip the rubber feet to the tabs to minimize sound and
vibration to the structure.

Level the unit, then use anchor bolts to secure it at the
four mounting points.

For installations in locations that require seismic or
hurricane tie downs, comply with local codes.
5
If the selected location is exposed to strong winds, install
a protective fence around the unit so that the fan can
operate correctly.

WARNING
•
The unit must be properly secured to the wall. If the
unit falls, it may result in crushing, electric shock, fire,
or explosion that could cause death, severe personal
injury, or property damage.
1
At the selected installation location (Step 1-1 on page
7), attach the L-bracket to the wall as follows:
‐
Install the bracket as close to the wall as possible.
‐
Insert rubber isolators between the bracket and
the wall to minimize sound and vibration to the
structure. Do not fully compress the isolators.
