Installation and Operating Precautions

(1) When lifting or moving the pump or equipment, pull the handle; never pull the cable, to avoid electric leakage.
(2) During transport, avoid collision and handle with care.
(3) When using this product, fit a leakage circuit breaker to prevent electric shock accidents caused by insulation deterioration as the product ages.
(4) Power voltage check: (A) single-phase: 220V; (B) three-phase: 380V; (C) when the pump runs under load, check whether the voltage is sufficient (the voltage must be the same as stated on the nameplate).
(5) The pump must be used at the rated voltage; the allowable voltage variation must be within ±10%.
(6) Be sure to use the grounding wire (the green core wire is the grounding wire).
(7) Power frequency check: before use, confirm that the power frequency marked on the product is consistent with the frequency used.
(8) If the cable is not long enough and must be extended: when extending the cable, note that an improper extension in wire thickness, size and length will cause voltage drop, difficult motor starting and shortened product life. The cable joint must not be placed in water.
(9) Confirm the rotation direction: (A) single-phase: the rotation direction is fixed before leaving the factory. (B) three-phase: if it runs in reverse, simply swap any two of the three power wires (if the pump runs in reverse, it will vibrate strongly, sound abnormal, deliver less water, and may cause the motor to burn out).
(10) Confirm that starting is normal; if it cannot start, check whether the impeller is stuck due to rust.
(11) Do not let the pump be buried in sludge or sand, and do not let debris block the pump piping; raise the pump on a pad where possible so that the pump bottom is exposed.
(12) Use piping of the same specification as the pump for drainage; using piping smaller than the pump outlet will increase the head loss and reduce the discharge due to improper piping, so please take note.
(13) When the pump is running, the water level must not be lower than the pump body; without water cooling the motor temperature rises quickly and the motor will burn out.
(14) Warning! The pump must not be used for flammable or explosive liquids such as gasoline, fuel oil or kerosene, and must not be used in flammable or explosive places.

Inspection, Repair and Maintenance

Every pump makes a normal sound when running. If during use the head, current, vibration or sound is found to be extremely different from usual, it is mostly a sign of an impending fault; inspection and repair must be carried out immediately. The fault troubleshooting below is attached for your reference. When inspecting the pump on site, be sure to switch off the power before inspection.

(1) Clearing debris from the pump: after pumping water containing silt, especially water containing cement, be sure to let clean water flow through the pump for a few minutes before stopping, to wash the inside of the pump. Otherwise silt, cement or debris will block the impeller and the pump body, and the pump will not start next time.
(2) Insulation resistance: check monthly. Use a 500V insulation resistance meter to measure the insulation resistance between each phase of the motor and the grounding wire, and confirm that it is above 10MΩ (if the result is below 10MΩ, repair immediately).
(3) Shaft seal and lubricating oil inspection: the life of the shaft seal device, calculated on pumping clean water, is about 5000–6000 hours, so check the lubricating oil at least every half year. When the lubricating oil becomes turbid or develops bubbles, repair immediately and replace the shaft seal and lubricating oil.
(4) Storage: before storing, if the lubricating oil check, impeller wear check and insulation resistance check are done first, the pump can be used immediately next time without waiting (and if repair is needed, there is ample time to do it). The inside and outside of the pump can also be washed with clean water; after the water has completely dried, store it in a dry indoor place.
