Vibration Isolators
Vibration Isolat ors
It is recommended that isolators be used on all upper level
installations or in areas where vibration transmission is a
consideration.
Figure 7: Isolator Locations
Transfer the unit as indicated under "Moving the Unit." In all
cases, set the unit in place and level with a spirit 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, flushing, 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 hold-
down bolts are not used.
Installation of spring isolators requires flexible piping
connections and at least three feet of flexible electrical conduit
to avoid straining piping and transmitting vibration and noise.
Refer to unit dimension drawing for mounting locations.
