4.2.5 Install the baseplate using stilt mounting
NOTICE:
The stilt-mounted baseplate is not designed to support static piping loads. Ensure that the suc-
tion and discharge piping are supported individually. Failure to do so may result in equipment
damage.
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 to install the
stilts.
2.
Install the lower part of the stilt assembly:
a) Screw the lower jam nut and adjusting nut onto the stilt.
b) Set the lower adjusting nut to the correct height.
The correct height depends on the required distance between the foundation/floor and the base-
plate.
c)
Put a washer onto the lower adjusting- nut.
3.
Install the stilt assembly on the baseplate:
a) Insert the stilt assembly into the baseplate's anchorage hole from below.
b) Put a washer onto the stilt.
c)
Fasten the stilt assembly with the upper adjusting nut by hand.
4.
Screw the upper jam nut onto the stilt by hand.
5.
Repeat steps 2 through 4 for all the stilt assemblies.
