Start and stop of the pump at different water levels may
be manual or automatic. If automatic start and stop is
required, a level regulator can be ordered (as option).
Level regulators are available for both 50Hz and 60Hz
markets.
The level regulator can be set at different operating lev-
els by adjusting the length of cable. A clamping bracket
situated below the lifting handle holds the level regulator
cable in place.
If continuous pumping is required at any time the level
regulator can be placed in a special rubber bracket on
the lifting handle thus eliminating the level regulator
function.

shock.
Earth continuity test
When performing the earth continuity test, measure be-
tween the earth wire in the motor cable and one of the
screws securing the strainer. See picture below.
Check that the mains voltage and frequence agree with
the specifications on the pump data plate.
Make sure that the pump is correctly earthed (ground-
ed).

is correctly connected by test-
ing it.

All electrical work shall be car-
ried out under the supervision of
an authorized electrician.
