If you will install the unit on the ground
or on a concrete mounting platform, do
the following:
1. Mark the positions for four expansion bolts
based on dimensions chart.
2. Pre-drill holes for expansion bolts.
3. Place a nut on the end of each expansion
bolt.
4. Hammer expansion bolts into the pre-
drilled holes.
5. Remove the nuts from expansion bolts,
and place outdoor unit on bolts.
6. Put washer on each expansion bolt, then

If you will install the unit on a wall-
mounted bracket, do the following:
CAUTION
Make sure that the wall is made of solid
brick, concrete, or of similarly strong
material. The wall must be able to support
at least four times the weight of the unit.
1. Mark the position of bracket holes based
on dimensions chart.
2. Pre-drill the holes for the expansion bolts.
3. Place a washer and nut on the end of
each expansion bolt.
4. Thread expansion bolts through holes in
mounting brackets, put mounting brackets
in position, and hammer expansion bolts
into the wall.
5. Check that the mounting brackets are
level.
6. Carefully lift unit and place its mounting
feet on brackets.
7. Bolt the unit rmly to the brackets.
8. If allowed, install the unit with rubber
