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.
