Clearances
All units require particular clearances for proper operation and
service. Installer must make provisions for adequate ventilation
air. Refer to Table 4 for clearances required for construction,
servicing, and proper unit operation.
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.
Units may be moved or lifted with a forklift. Slotted openings in
the base rails are provided for this purpose.
LENGTH OF FORKS MUST BE A MINIMUM OF 42 INCHES.
Do not permit overhanging structures or shrubs to
obstruct condenser air discharge outlet.
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 underside.
Before lifting, make sure the unit weight is distributed
equally on the rigging cables so it will lift evenly.
All panels must be secured in place when the unit is
lifted.
The condenser coils should be protected from rigging
cable damage with plywood or other suitable material.
