Installing Option Spring Isolators
In order to mount spring isolators, first remove the nuts
and screws on the spring isolator supports. Before the
unit is positioned, the isolator supports should be bolted
to the unit support. Position the 4 spring isolators,
screw out the adjusting screws on each isolator until
they reach out to match the isolator support holes.
Then lower down the unit on the adjusting screws.
The levelling bolts should now be rotated one (1) turn at
a time, in sequence, until the unit end sheets are clear
of the floor or foundation by 22 mm (7/8") and the unit
is level. Check that the unit is level, both longitudinally
and transversely. If the levelling bolts are not long
enough to level unit due to an uneven or sloping floor or
foundation, steel shims (ground, if necessary) must be
added beneath the isolator assemblies as necessary.
After the unit is levelled, wedge and shim under each
corner to solidly support the unit in this position while
piping connections are being made, pipe hangers
adjusted and connections checked for alignment. Then
the unit is filled with water and checked for leaks. The
levelling 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.
