12 Installation, Operating and Maintenance Instructions (Original Instructions)
ABS submersible sewage pump XFP 80C - 201G
8 Commissioning
Before commissioning, the pump should be checked and a functional test carried out. Particular attention should be
paid to the following:
-
Have the electrical connections been carried out in accordance with regulations?
-
Have the thermal sensors been connected?
-
Is the seal monitoring device correctly installed?
-
Is the motor overload switch correctly set?
-
Does the pump sit correctly on the pedestal?
-
Is the direction of rotation of the pump correct - even if run via an emergency
generator?
-
Are the switching ON and switching OFF levels set correctly?
-
Are the level control switches functioning correctly?
-
Are the required gate valves (where fi tted) open?
-
Do the non-return valves (where fi tted) function easily?
8.1
Types of operation and frequency of starting
All pumps of the XFP series have been designed for continuous operation S1 when either submerged or dry-
installed.
8.2
Checking direction of rotation
When three phase units are being commissioned for the fi rst time, and also when used on a new site, the
direction of rotation must be carefully checked by a qualifi ed person.
When checking the direction of rotation, the pump should be secured in such a manner that no danger
to personnel is caused by the rotating impeller or by the resulting air fl ow. Do not place your hand into
the hydraulic system!
When checking the direction of rotation, or when starting the unit, pay attention to the
START
REACTION
. This can be very powerful and cause the pump to jerk in the opposite direction to the
direction of rotation.
ATTENTION:
When viewed from above, the
direction of rotation is correct
if the impeller rotates in a
clockwise manner.
NOTE:
The start reaction is
anti-clockwise.
ATTENTION!
If a number of pumps are connected to a single control panel then each unit must be
individually checked.
ATTENTION!
The mains supply to the control panel should have a clockwise rotation. If the leads
are connected in accordance with the circuit diagram and lead designations, the
direction of rotation will be correct.
