Install the baseplate using spring mounting

NOTICE: The spring-mounted baseplate is designed only to support piping loads from thermal
expansion. You must support the suction and discharge piping individually. Failure to do so may result in
equipment damage.

The foundation pads are not provided with the baseplate. Make sure that the foundation pads are 316
stainless-steel plates, which have a 16-20 micro-inch surface finish.
Before you start this procedure, make sure that the foundation pads are correctly installed on the
foundation/floor (see the manufacturer's instructions).
1. Put the baseplate on a support above the foundation/floor.

Make sure that there is enough space between the baseplate and the foundation/floor in order to
install the spring assemblies.

2. Install the lower part of the spring assembly:

a) Screw the lower jam nut onto the spring stud.
b) Screw the lower adjusting nut onto the spring-stud, on top of the jam nut.
c) Set the lower adjusting nut to the correct height.

The correct height depends on the required distance between the foundation/floor and the
baseplate.

d) Put a washer, a follower, a spring, and one more follower onto the lower adjusting nut.

3. Install the spring assembly on the baseplate:

a) Insert the spring assembly into the baseplate's anchorage hole from below.
b) Put a follower, a spring, another follower, and a washer onto the spring stud.
c) Fasten the spring assembly with the upper adjusting nut by hand.

4. Thread the upper jam nut onto the spring stud by hand.
5. Repeat steps 2 through 4 for all the spring assemblies.
6. Lower the baseplate so that the spring assemblies fit into the foundation pads.
7. Level the baseplate and make the final height adjustments:

a) Loosen the upper jam nuts and adjusting nuts.
b) Adjust the height and level the baseplate by moving the lower adjusting nuts.
c) When the baseplate is level, tighten the top adjusting nuts so that the top springs are not loose in

their followers.

8. Fasten the lower and upper jam nuts on each spring assembly.
