Rigging

The chiller should be moved by lifting or by the base rail
designed for forklifting. Refer to the unit model number
for more details. Refer to submittal and lifting drawings
provided with order/unit to get unit lifting weights and
center of gravity dimensions. Refer to the rigging label
attached to the unit for further details.
WARNING Lifting and Moving Instructions!
Do not use cables (chains or slings) except as shown.
Lifting beam crossbars must be positioned so the lifting
cables do not contact the sides of the unit. Each of the
cables (chains or slings) used to lift the unit must be
capable of supporting the entire weight of the unit. Test
lift unit at minimal height to verify even level lift. Lifting
cables (chains or slings) may not be of the same length.
Adjust as necessary for even level lift. The high center
of gravity on this unit requires the use of an anti-rolling
cable (chain or sling). To prevent unit from rolling, attach
cable (chain or sling) with no tension and minimal slack
around compressor suction pipe as shown. Other lifting
arrangements could result in death, serious injury, or
equipment damage.

Lifting Procedure

Attach chains or cables to lifting beam, as shown
in lifting drawing provided with unit. Lifting beam
crossbars MUST be positioned so lifting cables do not
contact the sides of the unit. Attach the anti-rolling
cable to the circuit 2 compressor suction pipe. Adjust as
necessary for even level lift.

Unit Isolation and Leveling

Mounting
Construct an isolated concrete pad for the unit or
provide concrete footings at each of the four unit
mounting points. Mount the unit directly to the concrete
pads or footings. Level the unit using the base rail as a
reference. The unit must be level within 5 mm over the
entire length and width. Use shims as necessary to level
the unit.
Neoprene Isolator Installation (optional)
Install the optional neoprene isolators at each mounting
location. Isolators are identifi ed by part number and
color.
1. Secure the isolators to the mounting surface,
using the mounting slots in the isolator base
plate. Do not fully tighten the isolator mounting
bolts at this time.
2. Align the mounting holes in the base of the unit,
with the threaded positioning pins on the top of
the isolators.
3. Lower the unit on to the isolators and secure the
isolator to the unit with a nut. Maximum isolator
defl ection should be approximately 6.4mm.
Level the unit carefully. Refer to "Leveling".
Fully tighten the isolators mounting bolts.

NOTICE
Remove Shipping Spacers
For all RTWD 060-120 and all RTUD 060-120, remove and
discard the two shipping spacers with four bolts, located
underneath the oil separator, as shown in Figure 2
before starting unit. Failure to remove the spacers could
result in excessive noise and vibration transmission into
the building.
For RTUD 130-270 ton units, remove and discard the four
sets of shipping spacers (each including two spacers
and one bolt), located within the oil separator mounting
brackets, as shown in Figure 3 before starting unit.
Failure to remove the spacers could result in excessive
noise and vibration transmission into the building.
