Removal of Compressor Shipping Support

The Ultra-Aire 98H uses a compressor to power the
refrigeration system. To protect the compressor and
refrigeration system during shipping, a plastic tie wrap
secures it to the unit’s frame. Remove the tie wrap by
cutting the tie wrap and pulling from the unit as shown.
After removing tie wrap, insert plastic plugs provided
into the holes.

CAUTION!

REMOVE COMPRESSOR SHIPPING TIE FROM THE UNIT. FAILURE TO REMOVE SHIPPING TIE

WILL CAUSE EXCESS VIBRATION TO BE TRANSMITTED TO THE FRAME.
