Rigging
Foundation Support
The foundation must be level, smooth,
and capable of supporting the machine
weight. The machine legs should be
positioned over isolation pads. A
housekeeping pad or support rail is
recommended to elevate the machine
for maintenance. Any foundation pad
should provide adequate structural
support and keep the installed machine
level within 1/16-inch [1.6 mm] by length
and width for reliable operation.
Leveling marks on the evaporator and
absorber tube sheet can be used to
check the machine after it is positioned
on the pad.
Chiller Isolation
Isolation pads are provided with each
unit. The purpose of the isolation pad is
to distribute the machine weight and
minimize sound and vibration
transmission through the building
structure.
