5.1.2 Grundfos MS 6000 motors
• If the motor is delivered from stock, check the level of motor
liquid before fitting the motor to the pump. See fig. 3.
• When pumps are delivered direct from Grundfos, the level has
already been checked.
• Check the level in connection with service. See fig. 3.
The filling hole for motor liquid is placed at the top of the motor.
1. Position the submersible pump as shown in fig. 3. The filling
screw must be at the highest point of the motor.
2. Remove the screw from the filling hole.
3. Inject liquid into the motor with the filling syringe until the
liquid runs back out of the filling hole. See fig. 3.
4. Replace the screw in the filling hole and tighten securely
before changing the position of the pump.
Torque: 3.0 Nm.
The submersible pump is now ready for installation.

5.1.4 Franklin motors from 3 kW and up
Check the level of motor liquid in Franklin 4" and 6" motors by
measuring the distance from the bottom plate to the built-in
rubber diaphragm. The distance can be measured by inserting a
rule or a small rod through the hole until it touches the diaphragm.
See fig. 5.
Caution
Take care not to damage the diaphragm.
Fig. 5 Measuring the distance from bottom plate to
diaphragm
The table below shows the correct distance from the outside of
