The loss of a few drops of liquid fill will not impair the motor function. If any larger
amounts of leakage are suspected, the motor fill must definitely be checked.

5.2.4 Installing water storage tanks

If the pump set is intended for horizontal installation, submersible motors UMA 300
or 14D require a water reservoir.
ü The motor has been placed down in a horizontal position on a level and solid
surface. It has been secured against rolling off.
ü Position the motor with the connections for the water storage tanks at the
highest point.
ü The water storage tanks are on hand.
ü The motor fill has been checked with the motor in a vertical position.
ü Suitable liquid for topping up the motor fill has been prepared.
1. Remove the screw plugs from the top and bottom of the stator case. Remove
the joint rings.
2. Insert the water storage tanks (59-33) with new joint rings (411.51) into the
stator and screw them in tightly.
3. Fill the water storage tanks with the specified liquid fill until they overflow.
4. Close both water storage tanks with a screw plug with integrated vent valve
(741) and joint ring (411.51).
