3.1.3 Free-standing submerged installation

Pumps for free-standing submerged installation can
stand freely on the bottom of the pit or the like. See
fig. 4.
Fig. 4 Free-standing pump on strainer
Fit a flexible union or coupling to the outlet in order
to facilitate service on the pump and easy separation
of pump and outlet line.
If a hose is used, make sure that the hose does not
buckle and that the inside diameter of the hose
matches that of the pump outlet.
If a rigid pipe is used, fit the union or coupling, non-
return valve and isolating valve in the order
mentioned when viewed from the pump.
If the pump is installed in muddy conditions or on
uneven ground, support the pump on bricks or a
similar support.
Proceed as follows:
1. Lower the pump into the liquid by means of a
chain secured to the lifting bracket of the pump.
Place the pump on a plane, solid foundation to
make sure that the pump stands securely.
2. Hang up the end of the chain on a suitable hook
at the top of the pit and in such a way that the
chain cannot come into contact with the pump
housing.
3. Adjust the length of the motor cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation.
4. Fasten the relief fitting to a suitable hook.
Make sure that the cable is not sharply
bent or pinched.
5. Connect the power cable.
