Installation of Indoor Unit

1. Install Hangers

Install threaded hangers from ceiling supports. When locating hangers, allow enough room to open access panel(s). Be sure to allow for the recommended diffuser height outlined in the Diffuser installation section, page 6. Two nuts must be used on the end of each threaded hanger. Ceiling supports are supplied by others. Refer to diagram below.

NOTE

Refer to the Diffuser installation section, page 6, for instructions on mounting the diffuser.

2. Install Unit

Using sheet metal screws, attach the weatherhood/ thru-wall/filter section to the blower/burner section. The flange on the weatherhood/thru-wall/filter section should overlap the flange on the blower/burner section.

NOTE

Good duct practices should be followed for all ductwork. Ductwork should be installed in accordance with SMACNA and AMCA guidelines, NFPA 96 and any local codes. Reference the CAPS submittal for duct sizes.

3. Seal Wall Opening

Apply sealant around the perimeter of the weatherhood to prevent water penetration and drafts into the building.

NOTE

50/50 units are shipped with the louvered intake assembled to the unit and do not require a thru wall weatherhood.

Raise the assembled unit into place.

Using two nuts per hanger, fasten the unit supports to the hangers under the unit. Appropriate unit supports, such as the optional manufacturer hanging bracket kit, or c-channel and angle iron (supplied by others), should be used. Refer to the Indoor Mounting drawing.

In order to prevent the unit from swinging and to provide a safe environment for service and maintenance, additional measures must be taken to secure the unit in all directions.
