Installation of 1" Deflection Mounts

1. Floor or steel frame should be level and smooth.
2. For pad installations, isolators do not normally re-
quire bolting. If necessary, anchor isolators to floor
through bolt holes in the base plate.
Isolators must be bolted to the sub-
structure and the equipment must be
bolted to the isolators when outdoor
equipment is exposed to wind forces.
3. Lubricate the threads of adjusting bolt. Loosen the
hold down bolts to allow for isolator adjustment.
4. Block the equipment 10 mm (1/4 in.) higher than
the specified free height of the isolator. To use the
isolator as blocking for the equipment, insert a
10 mm (1/4 in.) shim between the upper load plate
and vertical uprights. Lower the equipment on the
blocking or shimmed isolators.

5. Complete piping and fill equipment with water,
refrigerant, etc.
6. Turn leveling bolt of first isolator four full revolutions
and proceed to each mount in turn.
7. Continue turning leveling bolts until the equipment is
fully supported by all mountings and the equipment
is raised free of the spacer blocks or shims. Remove
the blocks or shims.
8. Turn the leveling bolt of all mountings in either direc-
tion in order to level the installation.
9. Tighten the nuts on hold down bolts to permit a clear-
ance of 2 mm (1/8 in.) between resilient washer and
underside of channel cap plate.
10. Installation is now complete.
