4.3. Trial operation
WARNING:
➢
Make sure that the unit cannot roll or fall over and injure people or damage property.
➢
In some installations, the pump and the surrounding liquid may be hot. Bear in mind
the risk of burn injuries.
➢
Never start the pump while it is suspended, as the pump may jerk and cause serious
accident.
➢
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:
➢
Inspect the pump. Check that there is no physical damage to the pump or cables.
➢
Check the oil level in the oil housing (see chapter 5.4. Oil inspection and change ).
➢
Remove the fuses or open the circuit breaker, and check that the impeller can be
rotated freely.
➢
Check that the monitoring equipment (if any) works properly.
1. Operate the pump for a short time (1 to 2 seconds) , and then check the correct pump
rotation.
WARNING:
Before changing the connections to 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.
Use a phase rotation indicator to check the correct pump rotation.
NOTICE:
When using a phase rotation indicator, read carefully it’s the operation manual.
Two ways to check the correct pump rotation
By looking at the impeller; the rotation of the
impeller should be counter clockwise as
shown in the picture (1).
