Install the spring isolators at each unit mounting (load)
point, using the following procedure:
1. Elevate the unit (one side at a time) to allow access
to the base rail mounting holes.
2. Align the mounting holes in the base rail of the unit
with the positioning pin in the top of the
appropriate isolator.
3. Position the isolator to allow access to the
mounting holes in the base of the isolator.
4. Lower the unit onto the isolator. The positioning pin
on the isolator must engage into the hole of the
base rail. The clearance between the upper and
lower isolator housings should be approximately 1/
