Rigging and handling
•
The rooftop unit is not designed to be
handled by a fork-truck. NEVER use fork-truck
to unload, move or lift a unit.
•
Proper rigging and handling of the unit is
mandatory during unloading and setting into
position for safety and to retain warranty
status.
•
Handle the unit in an upright position to
avoid damage of internal components while
handling the unit.
•
Exercise care when moving the unit. Do not
remove any packaging until the unit is near
the place of installation.
•
All rigging and handling MUST be performed
by a qualified rigging contractor.
•
Refer to the unit's
Submittal Data
for the
exact unit weight, corner loads, and center of
gravity. As part of the submittal data a unit
specific rigging and handling instructions
document with lifting lug drawing is available.
•
Proper spreader bar(s) and cables that are
appropriate for the configuration and size of
the unit must be used during rigging.
•
Refer to Figure 6 and Figure 7 for the lifting
lug angles and examples. For exact lifting
lug locations, contact your local sales
representative or use the RTUToolkit rigging
and shipping document. All lifting lugs must
be used to prevent twisting of the equipment
structure.
•
Always use lifting straps with safe working
load limits above the weight of the unit. Use
either a 3/4 in. round pin anchor shackle or a
3/4 in. round pin chain shackle for each lifting
lug.
•
When blocks are used under the base rail
during transportation or storage, ensure a
block is located under each and every lifting
lug on both sides of the unit.
