INSTALLATION INSTRUCTIONS FOR
VMC SERIES AWR/AWMR AND CP
RESTRAINED MOUNTINGS
1. Floor should be level and smooth.
2. For indoor applications, isolators do not normally
require bolting. If necessary, anchor isolators to
floor through bolt holes in base plate. IMPORT-
ANT: Isolators must be bolted to substructure
and equipment to isolators when used under
outdoor equipment exposed to wind forces.
3. Lubricate threads of adjusting bolt. Loosen hold
down bolts to allow for isolator adjustment.
4. Block the equipment 1/4” higher than the speci-
fied free height of the isolator. To use the isolator
as blocking for the equipment, insert a 1/4” 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 revolu -
tions and proceed to each mount in turn.
7. Continue turning leveling bolts until equipment is
fully supported by all mountings and equipment is
raised free of the spacer blocks or shims. Remove
blocks or shims.
8. Turn leveling bolt of all mountings in either direc-
tion in order to level the installation.
9. Tighten nuts on hold down bolts to permit a clear-
ance of 1/8” between resilient washer and underside
of channel cap plate.
10. Installation is now complete.
