Step 3 Install Vent Piping
Refer to the indoor venting instructions I-6. Refer to your unit submittal to determine the correct venting option.
Step 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 Greenheck 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.
