Spring isolators typically ship assembled and ready for
installation. To install and adjust the isolators properly,
follow the provided instructions.
N N o o t t e e : : Do NOT adjust the isolators until the chiller is
piped and charged with refrigerant and water.
I I m m p p o o r r t t a a n n t t : : Do NOT block any serviceable components
such as the lubrication system with field-
installed devices such as spring isolators.
1. Position the spring isolators under the chiller as
shown in the preceding figure. Ensure that each
isolator is centered in relation to the tube sheet.

N N o o t t e e : : Spring isolators shipped with the chiller may
not be identical. Compare the data provided
in the unit submittal package to determine
proper isolator placement.
2. Set the isolators on the sub-base; shim as
necessary to provide a flat, level surface at the
same elevation for the end supports.
I I m m p p o o r r t t a a n n t t : : Support the full underside of the
isolator base plate; do NOT straddle
gaps or small shims.
3. If required, screw the isolators to the floor through
the slots provided, or cement the pads.
N N o o t t e e : : Fastening the isolators to the floor is not
necessary unless specified.
