Installation: Mechanical
The weight of the chiller will force the upper housing of each isolator down, perhaps
causing it to rest on the isolator's lower housing. Figure 18 illustrates spring isolator
construction.
6. Check the clearance on each isolator. If this dimension is less than 1/4" (6 mm) on
any isolator, use a wrench to turn the adjusting bolt one complete revolution up-
ward. Repeat this operation until a 1/4" (6 mm) clearance is obtained at all isolators.
7. After the minimum required clearance is obtained on each of the isolators, level the
chiller by turning the adjusting bolt on each of the isolators on the low side of the
unit. Be sure to work from one isolator to the next.
Remember that the chiller must be level to within 1/4" (6mm) over its length and width
and that clearance of each isolator must be 1/4" (6 mm).

Note:
The spring isolator must be
centered in relation to the tube sheet. Do
not
align the isolator with the flat part of
the chiller foot, because the tube sheet is
often off-center.
Note:
Place isolator near outside edge of
tube sheet as shown.
