Operation
Precautions
• Never operate the pump without safety devices installed.
• Never operate the pump with the discharge valve closed.
• Make sure that all safety guards are in place and secure.
• Make sure you have a clear path of retreat.
• Never work alone.
• Beware of the risk of a sudden start if the product is used with an automatic level control and/or
internal contactor.
Distance to wet areas
Electrical Hazard:
Risk of electrical shock when pumping or mixing near a lake, jetties, beaches, ponds, fountains, or similar.
There must be a safety distance of at least 20 m (65 ft.) between the person and the product if the person
is in contact with the pumped or mixed liquid.
Noise level
NOTICE:
The noise level of the product is lower than 70 dB. However, the noise level of 70 dB may be exceeded in
some installations and at certain operating points on the performance curve. Make sure that you
understand the noise level requirements in the environment where the pump is installed. Failure to do so
may result in hearing loss or violation of local laws.
Start the pump
WARNING:
• If you need to work on the pump, make sure that it is isolated from the power supply and cannot be
energized.
• Make sure that the pump 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.
• Make sure nobody is close to the pump when it is started. The pump will jerk in the opposite
direction of the impeller rotation.
NOTICE:
Make sure that the rotation of the impeller is correct. For more information, see Check the impeller rotation.
1. Check the coolant level in the seal housing.
2. Remove the fuses or open the circuit breaker, and check that the impeller can be rotated freely.
3. Conduct insulation test phase to ground. To pass, the value must exceed 5 megohms.
4. Check that the monitoring equipment works.
5. Start the pump.
