Outdoor Unit Installation
If you are installing the unit on a wall-mounted
bracket, follow these steps:
TO REDUCE VIBRATION OF WALL-MOUNTED UNIT
Before installing a wall-mounted unit, make sure
that the wall is made of solid brick, concrete, or
a similarly strong material. The wall must be able
to support at least 4 times the weight of the unit.
If allowed, you can install the wall-mounted unit
with rubber gaskets to reduce vibration and noise.
1. Mark the position of the bracket holes based on
the dimensions in the Mounting Dimensions chart
on the previous page.
2. Pre-drill the holes for the expansion bolts.
3. Clean dust and debris away from the holes.
4. Place a washer and nut on the end of each
expansion bolt.
5. Thread expansion bolts through the holes in the
mounting brackets. Then, put the mounting
brackets in position and hammer the expansion
bolts into the wall.
6. Check that the mounting brackets are level.
7. If the feet of the outdoor unit have rubber pads
already installed, and you’re using a MRCOOL
®
wall-mounted bracket, remove them before
attempting to mount the condenser to the bracket.
The mounting bracket has rubber isolating pads on
it that will take the place of these.
