Installation - Mechanical

14 CXRC-SVX01F-EN

Installation Preparation

Before installing the unit, perform the following

procedures to ensure proper unit operation.

1. Position the unit and skid assembly in its final location.

2. Test lift the unit to determine exact unit balance and

stability before hoisting it to the installation location.

See

“Unit Handling Procedure,” p. 13 for proper

rigging procedures and cautions.

3. Remove the skids from under the unit. See unit IOM

SCXF-SVX01*-EN, “Skid Removal” section. If you find

internal damage, file a claim immediately to the

delivering carrier.

4. Remove the protective shipping covers from the unit.

5. Verify isolators are properly tightened for operation.

See

“Unit Isolation,” p. 14.

Unit Isolation

The standard unit comes with 6” x 6” x 3/8” thick isolator

pads. Place these under the unit in the locations shown in

Figure 14, p. 15 through Figure 16, p. 15.

Spring Isolators

Unit mounting locations are shown in Figure 14, p. 15

through Figure 16, p. 15. Operating weights and weight

loading at each mounting location are provided in Table 5,

p. 14. Isolator placement instructions are also placed in the

control panel with other unit documentation. Isolators are

identified by spring color and by the isolator part number.

All units utilize CP-1-28 “green” isolators (20–32 ton units

use 4 isolators per unit, 35-40 ton units use 6, and 50–60

ton units use 8). Install spring isolators at each unit

mounting point using the following procedure:

1. Bolt the isolators to the mounting surface using the

mounting slots in the isolators base plate. Do not fully

tighten the isolators mounting bolts at this time.

2. Set the unit on the isolators: the isolator positioning

pins must register in the unit mounting holes. See

Figure 14, p. 15 through Figure 16, p. 15 for locations.

3. Ensure clearances between upper and lower isolator

housings are between ¼” to ½“. See isolator detail in

Figure 13, p. 14. A clearance of over ½” requires shims

to level the unit (see Leveling the Unit section on this

page).

4. Make minor clearance adjustments by turning the

isolator leveling bolt clockwise to increase clearance

and counterclockwise to decrease clearance.

If proper isolator clearance cannot be obtained by turning

the leveling bolt, level the isolators themselves. A ¼”

variance in elevation is acceptable.

NOTICE:

Equipment Damage!

Proper isolator clearance and unit level must be

achieved or structural damage may occur.
