Vibration Isolators
Vibration isolators are recommended for all roof-mounted installations or wherever vibration
transmission is a consideration. The isolators can be purchased from McQuay by the part numbers
shown in the table.
The unit should be initially on shims or blocks at the listed 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 is part of the isolator. Installation of spring isolators requires flexible piping
connections and at least three feet of flexible conduit to avoid straining the piping and transmitting
vibration and noise.

Chilled Water System
Water Piping (Applicable when the Unit is Field Connected to a Water
Type Evaporator)
Local authorities can supply the installer with the proper building and safety codes required for proper
installation.
Install piping with minimum bends and changes in elevation to minimize pressure drop. Consider the
following when installing water piping:
1.
Vibration eliminators to reduce vibration and noise transmission to the building.
2.
Shutoff valves to isolate the unit from the piping system during unit servicing.
