Note:
• All dimensions are in inches in accordance with ANSI Y14.
• Standard finish for housing is powder coated, for spring is powder coated, and for
hardware is zinc electroplate. For color, see the previous tables.
• Installation requires a bolting or anchoring mount to support the structure with a
minimum two 5/8 in. diameter bolt or two 1/2 in. diameter concrete anchors.
• All springs are designed for 50% over-travel.
• See Installation of optional spring isolators for installation instructions.
• Isolators with 1 in. deflection must be of the same class for the entire unit. That is, C2Ps
must be used at all locations on a selected unit, or all CPs.
• Pin 63 is for isolators, X = no isolators only active selection, 1 = 1 in. deflection not active,
N = neoprene not active.
Installation of optional elastomeric isolators
If ordered, elastomeric type isolator assemblies are supplied with the unit. The isolator load rating
can vary based on the location on the chiller. This is due to the weight distribution of the unit and
the isolators must be located as prescribed in the technical data portion of the chiller submittal
package. See Figure 13 for the locations. See Table 7 for isolator details.
Spring isolators are shipped fully assembled and must be positioned in accordance with the
submittal drawings or as otherwise recommended.
1. Set the isolators on the floor, housekeeping pad, or subbase, and ensure that all isolator
centerlines match the equipment mounting holes.
2. VMC Group recommends that the isolator base (A) be installed on a level surface. Shim or
grout as required, leveling all isolator bases to the same elevation. The maximum difference
that can be tolerated is 1/32 in. (0.794 mm).
3. Bolt or anchor all isolators to supporting structure using base slotted holes (B).
4. Remove the top bolt and washer.
5. Place the equipment on top of the isolators, making sure that the mounting holes of the
equipment line up with the isolator threaded hole (C).
