Support Assembly
2
Begin the installation process by assembling the support mounts.
1. Position one Component C support and one Component D support in such a way that the Component C
support is standing upright on its rectangular base and the Component D support is lying perpendicular
with the square base of Component D intersecting Component C's interior.
2. The four bolt holes near the base of Component C should be properly aligned with the four bolt holes near
the square base of Component D.
3. Take two Component M8x55 M-B bolts and two Component M8 M-D nuts. With the Component C support
standing upright and the Component D support pointed toward you, insert one Component M8x55 M-B
bolt in the top bottom hole, then tighten one Component M8 M-D nut over the exposed end of the bolt
extending out of the opposite side of Component C. The bolt should also extend through the top hole of
Component D.
4. Take the second Component M8x55 M-B bolt and extend it through the lower hole on Component C.
Attach the Component M8 M-D nut to the end.
5. Do not overtighten the nuts.
6. Next, take one Component E and insert it into the singular hole at the base of the upright Component C
support.
7. Finally, assemble two Component M8-25 M-A bolts, two Component B washers, two Component D8 M-C
washers, and two Component M8 M-D nuts. Push the M-A bolt through the B washer, then insert it through
the innermost slide hole in Component D. Place the M-C washer on the base of the M-A bolt, then secure it
in place with an M-D nut. Do not overtighten.
8. Repeat this process for the second set of components and insert them in the outermost slide hole in
Component D.
9. This completes the assembly for one of the support mount.
10. Repeat the process to assemble the second support mount.

Installation Of The Bracket
To properly install the bracket on a brick and concrete
structure, you will need an install site with a structure
strong enough to support the bracket and the
condenser, a pencil to mark, a hand-held drill, and a
level.
1. Use Wall Plate A and a pencil to mark the location
of the mounting holes. Use a level to ensure the
mounting holes are properly aligned.
2. After the holes are marked and aligned, use a
hand held drill with a 0.5 inch (12mm) drill bit to
drill a hole approximately 1.8 inches (45mm)
deep.
3. Insert one Component W-A into the center
mounting hole. Align Wall Plate A with the insert
Component W-A and the other two mounting
holes. The thick side of Wall Plate A should be on
the bottom and parallel to the ground.
4. Attach a washer and a nut to Component W-A. Do
not overtighten the nut.
5. Slide one previously assembled support mount
onto the lip of Wall Plate A from the left.
6. Slide the other previously assembled support
mount onto the lip of Wall Plate A from the right.
7. Mark four new mounting holes. Two mounting
holes should be marked for the left support
mount and two should be marked for the right
support mount.
8. Remove the support mounts.
9. Using the same drill bit and drill depth as before,
drill four mounting holes at the previously marked
locations.
10. Insert one Component W-A into each of the four
mounting holes.
11. Slide one previously assembled support mount
onto the lip of Wall Plate A from the left.
12. Slide the other previously assembled support
mount onto the lip of Wall Plate A from the right.
13. Align the support mounts with the mounting holes
and the inserted components. Attach a washer
and a nut to each Component W-A. Do not
overtighten the nuts.
