Particular attention should be paid to:
• the provision of venting to the sump
• installation of isolating valves on the inlet and discharge lines
• removal of any slack from the power cable by coiling and securing it so that it cannot be damaged during
operation of the pump
ATTENTION The power cable should be handled carefully during installation and removal of the
pump in order to avoid damage to the insulation.
ATTENTION! PE3 pumps must not be dry-installed without a cooling jacket.
When dry-installed the pump motor housing may become hot. In such a case, to avoid burn injury,
allow to cool down before handling.

discharge pipe and cable.
Arrange the cable run so that the cables will not be kinked or nipped.
Hoses, pipes and valves must be sized to suit the pump performance.
9�3�4 Venting of the volute
After lowering the pump into a sump full of water, an air lock may occur in the volute and cause pumping
problems. To clear the air lock, shake the pump, or raise the pump in the medium and then lower it again. If
necessary, repeat this venting procedure.
We strongly recommend that dry-installed XFP pumps are vented back into the sump by means of the drilled
and tapped hole provided in the volute.
