The installation of this product requires basic mechanical skills and a full understanding of the installation manual. If you feel you are not comfortable performing this type of work, please seek a qualified professional.
Before mounting the condenser bracket to the supporting surface, ensure the surface will support the combined weight of the bracket, condenser, and the attached components.
To safely lift and position the bracket or condenser, an assistant or mechanical lifting equipment may be needed.
When tightening mounting hardware (bolts, nuts, screws, etc.), _DO NOT _overtighten. Over tightening could cause long-term damage to the support bracket and weaken or reduce its weight capacity.

Wall Plate A

Assembly of Support Bracket Mounts

Begin the installation process by assembling the support bracket mounts.

Take one of the folded brackets (Component C) and unfold it into an “L” shape, so that it stands upright and is pointed towards you. Refer to Fig. 2.1.
Insert component D into the hole at the base of the rear of component C. Please refer to Fig 2.2.
Next, take two bolts (component M8x25 M-A) and place washers (component B) onto them. Then, insert the bolts with washers into the front and rear slide holes on the top of the base of component C. Next, put washers (component M-C) on the ends of each bolt and then secure with nuts (component M-D). DO NOT overtighten the nuts. Please refer to Fig. 2.1.
This completes the assembly of one support bracket mount. Repeat the same process for the second support bracket mount.

Installation Of The Bracket

To properly install the bracket, you will need to select a strong and permanent installation location that can support the weight of the bracket and the condenser. Tools needed: Pencil (to mark mounting hole location), hand- held drill, and a level.

Using Wall Plate A (with lip of plate at the bottom), place it against the wall to determine the correct mounting location. Use a level to align the wall plate and ensure it is parallel with the ground. Once level, use a pencil to mark the three holes on the surface it is to be mounted to. Please refer to Fig. 3.1.
Once the holes are marked and aligned, using a hand-held drill, with a 5/16 in (8 mm) drill bit, drill holes into the mounting surface with a depth of approximately 2-3/4 in (70 mm).
NOTE: If you are drilling into any type of masonry (concrete, brick, etc.) please use a masonry drill bit which is specifically made to drill into those types of materials.
Then, place the wall plate against the wall and align the mounting holes. Insert bolts, component W-A, through the wall plate and into the mounting holes. Tighten the bolts to secure the wall plate to the mounting surface. DO NOT overtighten the bolts.
Now, using the support bracket mounts you assembled in the first section, you will now slide them onto each side of the mounted wall plate. They will need to be slid into the correct position on the wall plate to accommodate the bottom of the condenser. Please refer to Fig. 3.
With the support bracket mounts in the correct position, you will now use a pencil to mark the bottom hole on each of the support mounts. Once marked, remove the support bracket mounts from the wall plate. Please refer to the image below.

NOTE: Component D, that you installed earlier in the installation, is actually a vertical leveling screw. If you are mounting the bracket to a wall that has an uneven exterior surface (such as vinyl siding), and find that the upright portion of the brackets (component C) does not sit vertically straight against the wall, you can use this screw to adjust it. It acts as a bumper that sits against the wall and can be adjusted in and out. Please refer to the image below.
You will now drill the holes you just marked on the mounting surface using the same drill bit and drill depth used when mounting the wall plate.
Then, slide the support bracket mounts back on the wall plate and align the mounting holes. Now, insert the bolts from component W-A into the mounting holes and tighten them. DO NOT overtighten the bolts.

CAUTION

Installers must verify that the supporting surface will safely support the combined weight of the equipment and all attached hardware and components.

Mounting The Air Conditioner

If the MRCOOL® condenser that is to be installed to the bracket has rubber pads on the bottom of the mounting feet, remove them before attempting to mount the condenser to the bracket. The bracket has rubber isolating pads that will take the place of these.

Slowly position the unit on the installed mounting bracket and make sure it Is firmly supported by the mounting bracket.

Maintenance

Check that the bracket is securely fastened and safe to use at regular Intervals.
Please contact your distributor if you have any questions.
