SECTION 3 - HANDLING, STORAGE, INSTALLATION AND REASSEMBLY
INSTALLING OPTIONAL SPRING ISOLATORS
If ordered, four identical spring type isolator assemblies
are furnished with the unit as shown in Figure 10 on
page 30. Use the following instructions to install the
optional spring isolators:
1. While the unit is suspended by the rigging, bolt
the isolators to the unit by inserting the cap screws
through the holes in the mounting bracket into the
tapped hole in the top of the isolator leveling bolts.
Then the unit can be lowered onto the oor.
2. Rotate the leveling bolts one turn at a time, in se-
quence, until the unit end sheets are clear of the
oor according to the dimensions.
3. Check that the unit is level, both longitudinally
and transversely. If the leveling bolts are not long
enough to level unit due to an uneven or sloping
oor or foundation, add as many shims as neces-
sary (grouted, if necessary) under the isolator.
4. After the unit is leveled, wedge and shim under
each corner to solidly support the unit in this posi-
tion while:
• Piping connections are being made.
• Pipe hangers are adjusted and tightened.
• Connections are checked for alignment and
tightness.
5. Fill the unit with water and check for leaks.
6. Adjust the leveling bolts, and remove the shims.
The unit should now be in a correctly leveled po-
sition, clear of the oor or foundation, and with-
out any effect from the weight of the piping.
