Rigging
Rigging holes are provided on all models. Caution should be exercised when moving these units. To prevent damage to the unit housing during rigging, cables or chains used must be held apart by spacer bars. The mounting platform or base should be level and located so as to permit free access of supply air. The unit weather hood may be removed for the rigging process. The condensing unit cover (wrapper) should be left in place.
Access Requirements
Provide adequate space at the compressor end of the unit for servicing. Provide two (2) feet of space above unit for service.
Mounting
The system requires an opening in the ceiling to the dimensions stated on page 3. Mounting rails are located at both ends of the chassis. Mounting rails may be used to attach unit to ceiling.
