3.1.3 Minimum space
Pumps installed with a float switch require a free
space between the float switch and the wall to
ensure free movability.
Pumps with side inlet require a free space between
the floating inlet strainer and the wall.
If you install the pump in a well or tank, the minimum
free space must be as shown in figs
2 and 3 .
Pumps installed without a float switch require a
space that corresponds to the physical dimensions of
the pump.
