SECTION 1 – INSTALLATION
INSTALLING OPTIONAL SPRING ISOLATORS
When ordered, 4 spring type isolator assemblies will
be furnished with the unit. The 4 assemblies are identi-
cal and can be placed at any of the 4 corners of the unit.
While the unit is still suspended by the rigging, the iso-
lators should be bolted to the unit by inserting the cap
screw(s) through the hole(s) in the mounting bracket
into the tapped hole in the top of the isolator leveling
bolt(s). Then the unit can be lowered onto the floor.
The leveling bolts should now be rotated one (1) turn at
a time, in sequence, until the unit end sheets are clear of
the floor by the dimension shown in
and the unit is level. Check that the unit is level,
both longitudinally and transversely (see Leveling the
Unit). If the leveling bolts are not long enough to level
unit due to an uneven or sloping floor or foundation,
steel shims (grouted, if necessary) must be added be-
neath the isolator assemblies as necessary.
After the unit is leveled, wedge and shim under each
corner to solidly support the unit in this position while
piping connections are being made, pipe hangers ad-
justed and connections checked for alignment. Then
the unit is filled with water and checked for leaks. The
leveling bolts should now be finally adjusted until the
wedges and shims can be removed. The unit should
now be in correct level position, clear of the floor or
foundation and without any effect from the weight of
the piping.
