Installation
Unit Isolation
To minimize unit sound and vibration transmission, one of the following installation methods
should be used:
1. Install the unit directly on an isolated (detached) concrete pad or on isolated concrete footings
located at each unit load point.
2. Install the optional neoprene or spring isolators at each mounting location. Refer to the
“Neoprene isolators” or “Spring isolator” section below.
Neoprene Isolators
Install the neoprene 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.
ƽ WARNING
Heavy Objects!
Use solid type blocks, i.e. 4" X 4" wood blocks or similar material to prevent collapsing. Keep
hands and other body limbs clear of elevated base rail while installing isolators. Failure to do so
could result in death or serious injury.
2. Align the mounting holes in the base rail of the unit with the holes in the top of the appropriate
isolator. Refer to Table 3 for the appropriate isolator for each load point.
3. Install a 1/2" NC bolt (field supplied) through the base rail of the unit into the threaded bolt hole
of the isolator. Position the isolator to allow access to the mounting holes in the base of the
isolator, then tighten securely.
4. Lower the unit and isolator onto the mounting surface. The maximum isolator deflection should
be approximately 1/4 inch.
5. Secure the isolator to the mounting surface using the base holes in the isolator.
6. Level the unit carefully. Refer to the “Leveling the Unit” section.
7. After the unit is level, tighten the isolator base mounting bolts to secure them to the mounting
surface.
