1.
Once again, check the nameplate of the pump to verify that its voltage and frequency are correct.
2.
Check the wiring, power supply voltage, the capacity of the ground leakage circuit breaker and the insulation
resistance of the motor.
NOTICE
Insulation resistance reference value is ≥ 30 MΩ. Please refer page 16 for the test method.
3.
Adjust the setting of the overflow protector (i.e. circuit breaker) to the pump's rated current.
4.
When using a generator, as much as possible avoid operating the pump in conjunction with other types of
equipment.
5.2 Trial operation
WARNING
Ÿ
Make sure that the unit cannot roll or fall over and injure people or damage property.
Ÿ
In some installations, the pump and the surrounding liquid may be hot. Bear in mind the risk of burn
injuries.
Ÿ
Make sure nobody is close to the unit when it is started. The unit will jerk in the opposite direction of the
impeller rotation.
CAUTION
Make sure to check the pump's direction of rotation when the pump is exposed to atmosphere. Operating
the pump in reverse while it is submerged in water will damage the pump, which may lead to current
leakage, electrical shock or fire.
NOTICE
Ÿ
Inspect the pump. Check that there is no physical damage to the pump or cables.
Ÿ
Check the oil level in the oil housing.
Ÿ
Remove the fuses or open the circuit breaker and check that the impeller can be rotated freely.
Ÿ
Check that the monitoring equipment (if any) works.
1.
.
Operate the pump for a short time (1 to 2 seconds), and then check the correct pump rotation
WARNING
Before changing the connections for reverse rotation, make sure that the power supply (i.e. circuit breaker)
is properly disconnected and that the impeller has stopped completely. Failure to observe this may lead to
serious accidents, including electrical shock, short or injury.
Ÿ
Use a phase rotation indicator to check the correct pump rotation.
NOTICE
When using a phase rotation indicator, read the operation manual with it.
