START-UP
- Replace the RED transport cap with the cap with a built-in dipstick.
- Check the oil level through the window or using the dipstick and, if necessary, top it up.
- Make sure that all fi ttings are securely tightened and that the pump feed is open.
- To expel the air present in the pump and make it easier to fi ll, we recommend you detach the delivery
pipe from the pump or keep the port/s open without any nozzles fi tted.
- Start the pump for 5/10 seconds until the liquid fl ows out smoothly from the delivery pipe or applian-
ces; if this does not happen, stop the pump and repeat the operation after a 10-second pause.
- Complete the connections and/or install the nozzles.
- Calibrate or regulate the valves; to prevent tampering, apply lead seals where possible, or paint the
regulating registers so that any tampering can be readily detected.
- All INTERPUMP pumps are tried and tested prior to shipment, the installation engineer is, however,
obliged to test the complete system for an adequate time to check for leaks, overheating, deterioration
in performance or calibration, etc.
