Application Considerations
Isolation and Sound Emission
Structurally transmitted sound can be reduced by elastomeric vibration eliminators. Elastomeric
isolators are generally effective in reducing vibratory noise generated by compressors, and
therefore, are recommended for sound sensitive installations. An acoustical engineer should
always be consulted on critical applications.
For maximum isolation effect, water lines and electrical conduit should also be isolated. Wall
sleeves and rubber isolated piping hangers can be used to reduce the sound transmitted through
water piping.To reduce the sound transmitted through electrical conduit, use flexible electrical
conduit.
Local codes on sound emissions should always be considered. Since the environment in which a
sound source is located affects sound pressure, unit placement must be carefully evaluated. Sound
power levels for chillers are available on request.
Servicing
Adequate clearance for evaporator and compressor servicing should be provided. Recommended
minimum space envelopes for servicing are located in the dimensional data section and can serve
as a guideline for providing adequate clearance.The minimum space envelopes also allow for
control panel door swing and routine maintenance requirements. Local code requirements may
take precedence.
