Locating And Installing Isolator Pads; Checking The Isolator Pad Deflection - York MILLENNIUM YS Manual

Installation
RIGGING (CONT'D)
Units shipped dismantled should be as-
sembled under the supervision of a
York representative.
If the cooler is to be field insulated, the insulation should
be applied while the unit is in the lift position, before the
unit is placed in position.

LOCATING AND INSTALLING ISOLATOR PADS

The isolator pads should be located in accordance with
the floor layout of the dimensional product drawing, Form
160.47-PA1. After the isolator pads have been placed
into position on the floor, lower the unit onto the pads.
Make sure the pads are even with the edges of the
mounting feet. When the unit is in place, remove the
rigging equipment and check that the chiller is level, both
longitudinally and transversely. See Figure 3.

The longitudinal alignment of the unit should be checked
by placing a level on the top center of the cooler shell
under the compressor/motor assembly. Transverse
alignment should be checked by placing a level on top
of the shell end sheets at each end of the unit.
The unit should be level within 1/4 inch from one end to
the other end and from front to the rear. If the chiller is
not level within the amount specified, lift it and place
shims between the isolation pad and the tube sheets.

CHECKING THE ISOLATOR PAD DEFLECTION

All isolator pads should be checked for the proper de-
flection while checking the level of the unit. Each pad
should be deflected approximately 0.15 inch (4mm). If
an isolator pad is under deflected, shims should be placed
between the unit tube sheet and the top of the pad to
equally deflect all pads. Refer to Figure 3.
