and tools suited for electrical operations.
Personnel must be qualified according
to national safety rules and regulations.
Only manufacturer- qualified personnel

Rigging
Follow all applicable regulations and
safety practices during rigging and lifting.
Prepare and follow written rigging and lifting plan.
Lifting must be directed by trained, professional rigger.
Spreader bars must be used and be long enough to pre-
vent rigging from contacting unit. Use only the desig-
nated lift points according to unit's IOM, and use ALL
lift points.

CABINET RISER INSTALLATION
Do NOT use the risers to lift or move the
cabinets.
Refer to Figure 3 on page 14 , which shows the
correct location of the cabinet in relation to the floor
sleeve and risers.
Risers are not designed to support or lift any part of the
cabinet. Do not use them to lift a cabinet. Risers are at-
tached using nylon ties to allow for slight adjustments
during installation, and expansion of riser column dur-
ing operation. Take care during installation to avoid
damage to risers and riser stub-outs.
Improper handling and installation of
risers could damage riser stub-outs and
valves and could result in property dam-
age, death, or serious injury.
Do not allow the risers to bottom out. Riser
stub-out should be centrally located with
the stub-out opening of the cabinet riser.
Do not allow riser stub-outs or risers to
contact cabinet sheet metal.
Do not drag risers on the floor while mov -
ing the cabinet.
When the risers are shipped loose, riser installation can
be completed before cabinet installation. When install-
ing risers, ensure the riser stub-outs are centered in the
the cabinet openings. Ensure that the risers cannot bot-
tom out in swage (see
Figure 1 on page 12
).
When risers are shipped attached to cabinets, complete
the installation of risers and cabinet at the same time.
Detaching the riser from the cabinet is unnecessary.
Placing the Cabinet
The correct location of the cabinet in relation to the
floor sleeve and risers is shown in Figure 3 on page
14 . To place the cabinet correctly, perform the fol-
lowing steps:
