INSTALL SPRING ISOLATION — Spring isolation may be
purchased as an accessory from Carrier for field installation. It
may also be field supplied and installed. Spring isolators may be
placed directly under machine support plates or located under
machine soleplates. See Fig. 14. Consult job data for specific ar-
rangement. Low profile spring isolation assemblies can be field
supplied to keep the machine at a convenient working height.
Obtain specific details on spring mounting and machine
weight distribution from job data. Also, check job data for
methods to support and isolate pipes that are attached to spring
isolated machines.
NOTE: It is recommended that any installation other than the
ground floor should have spring isolation for the chiller and
piping vibration isolation.
NOTE: These isolators are not intended for seismic duty, but
are intended to reduce the vibration and noise levels transmit-
ted from the chiller to the surrounding environment. For instal-
lations adjacent to areas that are sensitive to noise and/or
vibration, use the services of a qualified consulting engineer or
acoustics expert to determine whether these springs will pro-
vide adequate noise/vibration suppression.
