INSTALLATION DO’S AND DON’TS
Figure 5.4. - Short circuiting of vibration mounts
Don't allow short circuiting of vibration mounts.
Do ensure vibration mounts are free from short circuiting by
making sure that the hanger rods are central and not in contact
with the hanger cage. Ensure no debris, or other connection is
creating another path through which the vibration could
transmit.
Spring fully compressed
Don't overload spring mounts.
Ensure that spring mounts are sized correctly for the job. Be
careful to include the weight of ductwork (and any other piece of
equipment) if they are going to be supported by the vibration
isolators. Also ensure spring mounts incorporate neoprene or
rubber pads to eliminate noise which can travel through a steel
spring.
