WARNING
The pump must not be switched on
when it is not completely filled up.
ATTENTION
Seen from the top of the motor the
pump should rotate clockwise. See
7.1.1 Indicators 16 (B). In case of a 3-
phase motor the rotating direction can
be changed by exchanging two of the
three phase wires.

Close the fill plug.
5.
Fully open the suction shut-off valve.

1.
Remove the fill plug (B) from the top bracket.
2.
Close the outlet shut-off valve.
3.
Fill the pump housing to the maximum through
the fill plug with the liquid that is to be pumped.
4.

5.
Check the rotational direction of the pump.
6.
Open the outlet shut-off valve.
7.4.3
After an extended period of non-
operation or storage
During first start-up, check the mechanical seals for
leakage due to seizure or dehydration of the
lubricating film. If so, please proceed as following:
1.
Turn shaft manually or;
2.
Start up the pump, then open and close the
outlet shut-off valve quickly during operation.
3.
Check if the mechanical seal is still leaking.
If the shaft is still leaking:
1.
Disassemble the mechanical seal.
2.
Thoroughly clean and decrease the running
surfaces.
3.
Assemble the mechanical seal again and retry
start-up.
If this doesn’t solve the shaft leakage, replacement of
the mechanical seal is necessary.
