Rigging - Daikin Vision Installation And Maintenance Manual

Rigging

WARNING
A licensed and/or professional rigger is responsible for
developing a safe lift plan to meet local/national/international
codes.
DANGER
Use all lifting points. Improper lifting can cause severe
personal injury, death or property damage.
DANGER
ACCIDENT HAZARD. Do not forklift. Rig the unit only from
lifting points. Verify unit is secure before lift. Failure to comply
could result in personal injury or death.
Extended size Vision air handlers ship as separate sections,
completely assembled, or in modules of assembled sections.
The unit must be rigged as it ships from the factory . Do
not rig units after assembly . Each section ships with a
factory installed base rail and must be lifted via the retractable
(or removable for ship sections less than 49") lifting brackets
provided on each section (see
To prevent damage to the unit cabinetry, use spreader bars.
Position spreader bars to prevent cables from rubbing the
frame or panels. Before hoisting into position, test lift for
stability and balance. Avoid twisting or uneven lifting of the unit.
A fan array or coil section might have a tall, thin aspect ratio.
The center of balance on these sections can be high and make
the section prone to tipping during the lift. Care should be
taken when lifting units with a tall, thin aspect ratio.
Rigging Instructions
DANGER
DO NOT LIFT FROM 2" HOLES AT ENDS OF UNIT. Failure to
comply may result in personal injury or death.
Use proper sized shackles and hooks for rigging the unit. Rig
the unit according to the instructions listed below and connect
to lifting points as shown in
1. The unit must be rigged as it ships from the factory. Do
not rig units after assembly. The 2" holes at the end of
the unit are for tie down purposes only. Do not lift from
these points. See lifting points in "Figure A" and "Figure
B" (Figure 3).
2. The spreader bar length must be equal to (or no greater
than a foot longer than) the shortest dimension (width or
length) of the unit. Install the spreader bar parallel to the
shortest dimension.
3. On narrow sections, the lifting brackets will already be
exposed. For wide sections, the lifting brackets need to
be extended. To do this, cut the wire-tie which is holding
the bracket and retaining pin. Pull the bracket until the
retaining pin hole is exposed. Slide the retaining pin into

the hole and secure it with the provided spring clip and
washers. See details in "Figure B"
4. Fasten four separate cables to each of the four lifting
brackets extending from the middle of the section. Use
long enough cables so that the angle between the cables
and the ground is a minimum of 60º.
5. To attach rigging equipment, the large lifting bracket
bolt may need to be removed. Clevises or rigging hooks
can be used by attaching them around the provided bolt.
Examples of proper connections are shown in "Figure C"
( Figure 3).
6. Before hoisting into position, test lift for stability and
balance. Adjust cable lengths to avoid uneven lifting of
unit.
