WARNING
WARNING
If people are likely to come into
physical contact with the pump or pumped
media (liquid), e.g on construction sites or farms etc.,
the grounded socket must have an additional ground-
fault protection device (GFI) connected. When pumping
near a lake (Jetties, beaches, ponds and fountains etc.) a
safety-distance of at least 65 ft. (20 meters) between the
people and the pump is applicable. The pump must never
be placed directly into a swimming pool unless it is shut
down for maintenance. If used in connection with
swimming pools, special safety regulations apply.
LEVEL SWITCH OPERATION
Pump control by use of level switch.
Operation
BEFORE STARTING
Check the oil level in the oil casing.
Remove the fuses or open the circuit breaker and check
that the impeller can be rotated by hand.
Check that the monitoring equipment (if any) works.
Check the direction of rotation. The impeller shall
rotate clockwise, as viewed from above. When started,
the pump will jerk in the opposite direction to the
direction in which the impeller rotates. See the figure.
STARTING JERK
Installation
Run the cables so that they do not have any sharp bends
and are not pinched.
Connect the motor cable to a grounded power supply.
See “Electrical connections”.
Connect a discharge hose to the threaded discharge
connection. The pump is now fitted with a discharge hub
which may be adjusted to provide either vertical (std.)
or horizontal discharge. Simply remove the (2) hex head
cap screws holding the discharge hub, turn the discharge
hub 180º and reinstall the (2) screws.
Lower the pump into the sump.
Place the pump on a base which will prevent it from
sinking into a soft sump bottom. Alternati vely, the pump
can be suspended by its handle just above the sump bot-
tom.

warning may cause a lethal accident. Make sure that the
ground lead is correctly connected by testing it.
All electrical work shall be carried out under the supervision
of an authorized electrician.
Local codes and regulations shall be complied with.
