4. Operation
IOM manual - SB series 21
By looking from the top of the pump.
Because the impeller cannot
be seen in this
position, the best way to check the rotation
is check the kick back motion of the pump
when the pump just starts. The kick back
motion of the pump should be counter
clockwise as shown in the picture (2).
NOTICE:
For the SB(…)E… pump , you should use a screwdriver metal body so that the water level sensor
probe and guide rod are connected, otherwise the pump cannot start (see chapter 1.8 . SB(…)E
technical data and function) .
To reverse the rotation, the following countermeasure must be taken.
COUNTERMEASURE:
Interchange two of the three wires designated U, V,
and W, respectively.
2. Operate the pump for a short time ( ≤ 1 minute) and perform the following checks:
➢
Operating current: use an AC ammeter (clamp), measure the current at the phase U, V,
and W that are connected to the terminal board.
➢
Operation voltage: use an AC voltmeter (tester) to measure the voltage at the terminal
board.
➢
Power supply voltage tolerance: within ±10% of the rated voltage (see chapter 1.2.
Pump design )
➢
Vibrations
CAUTION:
If the pump generates a considerable amount of vibration, noise, or smell, disconnect the power
supply immediately and contact Tapflo for further support.
3. Continue operations if no abnormal conditions are found during the trial operation.
4.4. Operation
WARNING:
➢
The pump may be extremely hot during operation. To prevent burns, do not touch the
pump with bare hands.
➢
Do not insert your finger or any object into the pump's inlet opening. Doing so may
cause injury, electrical shock, short, or fire.
➢
When the pump is not used for a long time, make sure that the power supply (such as
a breaker) is properly disconnected. If the wiring insulation deteriorates with the power
supply connected, it may cause current leakage, electrical shock, or fire.
