Vibration Isolators
Vibration isolators are recommended for all roof mounted installations or wherever vibration
transmission is a consideration.
Table 1 and Table 2 list isolator point loads for all unit sizes. Figure 4 shows isolator locations. See
Dimensional Data for detailed dimensions required to secure each isolator to the mounting surface.
The spring flex isolators are white type CP2-32, McQuay kit number 350014821 provides the
required four per unit.
