Positional requirements
The pump is suitable for
vertical as well as horizontal
installation, however, the
pump shaft must never fall
below the horizontal plane,
see fig. 4.
To refill the motor, proceed as follows:
1. Remove the cable guard and separate
the pump end from the motor.
2. Place the motor in vertical position
with an inclination of approx. 10°.
3. Remove the filling plug using a
screwdriver or a similar tool.
4. Inject motor liquid into the motor with
a filling syringe or similar tool,see fig. 3.
5. To allow possible air to escape, move
the motor from side to side. And turn the
shaft.
6. Replace the filling plug and make sure it is tight.
7. Assemble pump end and motor.
8. Install the cable guard.
The pump is now ready for installation.
8. Electrical connection
General
The electrical connection should be carried out by an authorized
electrician in accordance with local regulations.
Before starting work on the pump, make sure the
electricity supply has been switched off and that it cannot be
accidentally switched on. The pump must be grounded. The
pump must be connected to an external mains switch.
The supply voltage, rated maximum current and power factor (PF) appear
on the motor nameplate. The required voltage for GRUNDFOS
submersible MSE3-NE motors, measured at the motor terminals, is +6%/–
10% of the nominal voltage during continuous operation (including
variation in the supply voltage and losses in cables).
If the pump is connected to an installation where a Ground Fault circuit
breaker (GFI) is used as additional protection, this circuit breaker must trip
out when ground fault currents with DC content (pulsating DC) occur.
Supply voltage:1 x 100-115V or 1 x 200-240 V +6%/–10%, 50/60 Hz.
The current consumption can only accurately be measured by means of a
true RMS instrument. If other instruments are used, the value measured
will differ from the actual value.
The Redi-Flo3 pumps can be connected to a Redi-Flo3 status box.
Note: The pump must never be connected to a capacitor or to
another type of control box other than a Redi-Flo3 status box.
The pump must never be connected to an external frequency
converter.
Motor protection
The motor has built-in automatic thermal overload protection and requires
no additional motor protection.
Connection of motor
The motor can be connected directly to the main circuit breaker.
