NOTE
The compressor is mounted to the cabinet base by four bolts that are inserted from the
underside of the base. In order to remove the compressor, it is necessary that the entire air
conditioner be raised and placed on blocks of sufficient height to allow for removal of
these bolts from below the base.
DO NOT LIFT without holding unit in upright position. Otherwise unit will fall over.
(2) Attach an overhead hoist to the lifting handle on each side of the cabinet, using a sling and spreader
bar.
(3) Raise the cabinet and place it on blocks at least four inches high. Be sure the blocks do not obstruct
the holes in the base through which the compressor mounting shoulder screws must be removed.
