RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation. Rig
the unit by attaching chain or cable slings to the lifting holes
provided in the base rails. Spreader bars, whose length
exceeds the largest dimension across the unit, MUST be
used across the top of the unit.
If a unit is to be installed on a roof curb other than a
YORK roof curb, gasketing must be applied to all
surfaces that come in contact with the unit under-
side.
