Trane RTHC - Alternate Moving Method; Isolation Pads

Installation, Operation and Maintenance 2 - 7
4 Attach cables to lifting beam. Total lifting weight,
lifting weight distribution and required lifting beam
dimensions are shown in the rigging diagram
shipped with each unit and in
Figure 6 . The lifting
beam crossbar must be positioned so the lifting
cables do not contact unit piping or electrical
panel enclosure.
WARNING
Connect an anti-rotation strap
between the lifting beam and com-
pressor before lifting unit. Failure
to do so may result in personal
injury or death should a lifting
cable fail.
5 Connect an anti-rotation strap or cable loosely
between the lifting beam and the threaded
coupling or eyelet provided at the top of the
compressor. Use an eyebolt or clevis to secure
the strap at the coupling or eyelet.
NOTE: The anti-rotation strap is not a lifting chain,
but a safety device to ensure that the unit cannot tilt
during lifting.
Alternate Moving Method
6 If it is not possible to rig from above as shown in
the figures, the unit may also be moved by jacking
each end high enough to move an equipment
dolly under each tube sheet support. Once
securely mounted on the dollies, the unit may be
rolled into position.
Proper jacking locations are shown in
Figure 6
and by the rigging diagram that ships with the unit.
Isolation Pads
NOTE: The elastomeric pads shipped (as standard)
are adequate for most installations. For additional
details on isolation practices, refer to Trane
Engineering Bulletin RLC-EB-3, or consult an
acoustical engineer for sound-sensitive installations.
7 During final positioning of the unit, place the
isolation pads under the evaporator and
condenser tube sheet supports as shown in
Figure 7 . Level the unit as described in the next
main paragraph.
NOTE: Durometer values for isolator pads are a
measure of resilience. See Figure 7 .
