4.7 Installing Optional Spring Isolators

When ordered, 4 spring type isolator assemblies will be

furnished with the unit (see table below). The 4

assemblies are identical and can be placed at any of the

4 corners of the unit.

While the unit is still suspended by the rigging, the

isolator mounting brackets should be bolted to the unit .

Place the four spring isolators in position. The threaded

adjusting bolts in each isolator should be screwed out of

the isolator until the extended head of the screw fits

snugly into the isolator bracket hole. The unit should be

lowered over the adjusting bolts.

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 by 22 mm and the unit is level. Check that the

unit is level, both longitudinally and transversely (see

Levelling the Unit). If the levelling 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 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 (spring isolator deflection should be

approximately 25 mm).
