9. Piping

• The pump should only be gripped by the two flats
at the top of the pump, see fig. 9.
• The pump can be installed vertically or horizontally.
During operation, the pump must always be com-
pletely submerged in water.
• When plastic pipe is used, a stainless steel safety
wire is recommended for lowering and lifting the
pump. Fasten the wire to the eyelet on the pump,
see fig. 10.
• The threaded joints must be well cut and fit to-
gether tightly to ensure that they do not work
loose.
