allow the unit to be picked up thru lifting eyes in the brackets.The lifting brackets are shipped attached
to the back panel of the ECU. Attach the brackets to the left and right side panels as shown in Figure
2. The 4 screws for attaching the brackets are shipped in the holes at the top of the side panels. When
attaching the brackets, make sure the top of the bracket is angled towards the center of the ECU.

Mounting The Unit

1. For wiring into the back of unit, locate the lower of the two knockouts on the wall side of the unit.
Drill a one inch hole in the shelter wall to match this opening. Allow sufficient clearance to run
3/4" conduit through the hole and to the unit.
2. Lift the unit into position using an appropriate and safe lifting device.
3. Make sure that the duct flanges are properly aligned with the wall opening. Adjust as necessary.
4. Note the holes in each side flange. Using the holes for guides, drill holes through the wall with a
drill bit. Insert the bolts through the flanges. Install nuts and washers on the inside of the shelter.
Tighten the bolts to secure the unit.
5. Apply a bead of silicone where the side and top flanges contact the exterior wall.
6. On the inside of the shelter, install the wall sleeves in the supply and return air openings. The sleeves
may be trimmed to fit flush with the inside wall.
7. Check the fit of each sleeve to its mating flange for possible air leaks. Apply silicone sealer to close
any gaps. Install the air return and supply grilles.
