Installation of Indoor Unit

NOTE

To prevent premature heat exchanger failure, do not locate units where chlorinated, halogenated, or acid vapors are present.

1. Install Hangers

Install threaded hangers from ceiling supports. When locating hangers, allow enough room to open access panel(s). Two nuts must be used on the end of each threaded hanger. Ceiling supports are supplied by others.

2. Install Unit

Raise the unit into place. Using two nuts per hanger, fasten the unit supports to 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.

Using self-tapping screws, attach ductwork to unit. 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.

NOTE

Two nuts must be used on each end of each threaded hanging rod for proper support.

WARNING

All factory-provided lifting lugs must be used when lifting any unit. Failure to comply with this safety precaution could result in property damage, serious injury or death.

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. Install Vent Piping

Refer to the Indoor Venting Instructions. Refer to your unit submittal to determine the correct venting option.

NOTE

The use of a duct adapter is recommended on a downblast (DB) arrangement to align the ductwork with the supply unit. The duct adapter is only a guide and is not to be used as support for the ductwork.

3. Apply Sealant

Apply an appropriate sealant around the perimeter of the curb and duct adapter(s) to isolate fan vibration and prevent water penetration.

4. Install Unit

Use a crane and a set of spreader bars hooked to the

factory lifting lugs to lift and center the unit on the curb/equipment support(s).

Use self-tapping
