Operation
Startup Procedures
Following installation, the following standard startup procedures are to be carried out to ensure pump function.
7.16 Warning
Do not run the pump dry. Running the pump without sufficient water will result in damage to equipment. Ensure that a sufficient water level is maintained.
1. Ensure that all obstructions have been removed.
2. Carry out a visual inspection of the pump ensuring no damage has occurred during installation.
3. Look through the plexiglas to check that there are no obstructions.
4. Check that the pump is filled with water. If not, remove the plug on the side of the suction chamber. Fill the pump with water. Re-fasten the
plug.
5. Ensure that the inlet and outlet pipes are securely fastened.
6. Ensure that the electrical connections are according to the motor name plate.
7. Remove the fan cover. Manually rotate the shaft by hand turning the fan. Ensure that all moving parts rotate freely without obstruction. Re-fit
the fan cover.
8. Turn on the power supply.
9. Check the rotation direction is in accordance with the serial number label. Observe the rotation on the motor end of the pump.
10. Check that the pump generates vacuum by operating the system (i.e. flush the toilet).
11. If abnormal operation, vibration or noise is experienced, shut down the pump immediately. Refer to the troubleshooting guidelines.
Startup Testing
1. Leak test the pump by filling the pump with water and checking for leaks. Any indication of leaking should be fixed using approved methods by
a qualified person. See the products service and maintenance information for details. If no leak is found the pump is deemed acceptable.
2. Test the amperage to ensure that results are within the given readings on the motor name plate.
Service and Maintenance
Intended Use
To maintain the expected operational lifetime, the following must be adhered to.
1. Do not pump liquids containing cleaners that create foam.
2. Minimize pumping of liquids containing caustic cleaners (such as drain cleaner) or bleach.
3. Minimize pumping of chlorine or corrosive cleaners.
Mild soap or biological cleaners are recommended. See Jets Vacuum AS product range for suitable cleaning solutions.
Scale Build Up
Pumps used for pumping wastewater are subject to mineral scale build-up. Regular follow-up during maintenance intervals is recommended based
on pump usage. Mineral scale build-up, if left untreated, may affect the performance of the pump.
To treat mineral scale build-up, it is necessary to flush a suitable descale solution through the pump. Jets™ descale products are recommended.
Annual Descaling of the Vacuumarator™ Pump
1. Shut down the pump. Follow step 1 to 13 under the Shutting down the Vacuumarator™ pump.
2. Re-attach all the parts that were removed to drain the pump.
3. Fill the pump with Jets™ Descale Gel, until it overflows the inlet of the pump.
4. Allow to react for a minimum of 24 hours.
5. Connect the inlet pipe to the suction side of the pump.
6. Connect the outlet pipe to the pressure side of the pump.
7. Open the valves on the inlet and the outlet of the pump, if installed.
8. Connect the power to the pump and set it into operation.
9. Flush the pump with water through the connection on the side of the suction chamber or through the flap cleaning valve.
Cleaning or Flushing the Vacuumarator™ Pump
Fresh water supply may be connected to the suction chamber on the pump to flush and clean, when necessary, and to fill the pump with water
after service.
