installations or in areas where vibration transmission is a
consideration.

Table 16: Vibration Isolator Mounting Locations (Packaged
Chillers)
Transfer the unit as indicated under Moving the Unit.“ In
all cases, set the unit in place and level. When spring-type
isolators are required, install springs running under the main
unit supports.
The unit should be set initially on shims or blocks at the listed
spring free height. When all piping, wiring, ushing, charging,
etc., is completed, the springs are adjusted upward to loosen
the blocks or shims that are then removed.
A rubber anti-skid pad should be used under isolators if
holddown bolts are not used.
Installation of spring isolators requires exible piping
connections and at least three feet of exible electrical conduit
to avoid straining piping and transmitting vibration and noise.
Refer to unit dimension drawing for mounting locations.
