Our factory is neither responsible for nor is reliable for paying compensation for personal injury, pump damage and other property losses caused by violation of safety cautions.

APPLICATIONS

1. It is applicable to household water supply, equipment support, small airconditioning system, pipeline pressurization, garden watering, vegetable greenhouse watering, fish breeding and poultry raising, etc..
2. Transfer clean water and other non-corrosive liquids with low viscosity; do not transport inflammable, explosive, gasified liquids and liquids containing solid particles or fibers. The PH of water must between 6.5 and 8.5.

Remark:
This series of pump could be transformed into automatic water pump, which is realized through external automatic plant that is composed of pressure switch, pressure tank, etc.. Function features of the automatic pump are as follows: when the power is on, turn on the water tap and the pump will start working automatically; when the water tap is turned off, the pump will stop working automatically. If a water tower is used along with the automatic pump, connect to the upper limit switch and the pump will start or stop working automatically with water level in the water tower.

PIPELINE INSTALLATION

This product should be installed and maintained by personnel who is proficient in this manual and has special qualifications. Installation and operation should be in accordance with local regulations and recognized operation standards. Install pipelines properly as stipulated in the manual and meanwhile conduct frost protection measures for the pipeline.

1. For pump installation, the inlet pipe should be as short as possible with the least turnings. The pump should be installed in ventilated and dry environment. It could be installed outside, provided having proper covering to prevent rain and wind.
2. For pipeline use, valves should be installed on inlet and outlet pipelines.

2. INSTALLATION PRECAUTIONS FOR INLET PIPELINES
   1. While installing the electric pump, do not use too soft rubber tube for the inlet pipeline, avoiding to be sucked flat.
   2. The foot valve should be vertically placed and installed 30cm from water bottom to avoid sucking in sands and stones (B2);
   3. Joints of the inlet pipelines should be sealed with the least elbows, no water can be sucked.
   4. Diameter of the inlet pipe should be at least in accordance with that of the water inlet, so as to avoid too much water loss which will influence outlet performance.
   5. Pay attention to drop of water level while using, the foot valve should not be above the water surface (B1).

   6. In case the inlet pipe is longer than 10m or its lifting height exceeds 4m, the pipe diameter should exceed diameter of water inlet of the pump.
   7. Ensure the pumped will not be affected by pipeline pressures while installing the pipelines.
   8. Filter should be installed in inlet pipelines so as to avoid solidparticles to enter into the electric pump.
3. INSTALLATION PRECAUTIONS OF THE OUTLET PIPELINE
   Pipe diameter of the outlet pipeline should be at least in accordance with that of the water outlet, so as to reduce its voltage drop, high flow rate and noise to the minimum.

Electrical Connection

Unless the power is off, do not wiring the junction box. The electric pump should have reliable grounding to prevent current leakage with leakage protection switch being equipped.

1. Electrical connection and protection should be conducted according to stipulations. Specification of working voltage is marked on the nameplate; please ensure the motor is in accordance with power supply.
2. In case the working area of the electric pump is too far from the power supply, power transmission lines should be of a heavier gauge, otherwise the electric pump cannot work normally because the voltage drop is too dramatic.
3. A rubber extension cable shall be applied for the electric pump in case of outdoor use.
4. Check rotation of the motor (three-phase motor).

START-UP AND MAINTENANCE

Do not start up the pump before the pump chamber is filled with water. Do not touch the electric pump unless its power has been cut off for at least 5 minutes. Do not dismount the pump body unless water in the pump chamber is empted.
Rotate the fan blade before startup, check whether the pump rotation is flexible and then unscrew the water-filling plug, fill the pump chamber with clean water from the water injectionhole, then tighten the plug screw after the air has been completely discharged. Set the valve in a smaller flow in start-up and adjust to the required flow after water discharging (working range is displayed on the nameplate).
Attention:

1. The pump chamber should be filled with water before first use and water refilling is unnecessary in the future.
2. In case no water is discharged after being started for more than 5 minutes with water filled, turn off the electric pump, re-fill water or check whether the inlet pipeline has leakages.
3. In case of any frost and ice damages, please open the drain plug to empty water in the pump chamber. When start up the pump again, open the drain plug, fill water and tighten it and then the pump is usable.

4. In case not use for a long time, water in the pump should be emptied. The pump body, impeller and support should be cleaned and coated with anticorrosive oil before they are put in a ventilated and dry place for use.
5. In case the pump is halted for a long time, start it up again according to above diagram.
6. In summer or when the ambient temperature is high, pay attention to ventilation, avoid dew on electrical parts which will result in electrical faults.
7. In case the motor is hot or abnormal, cut off the power immediately and check faults according to the following table.

TROUBLESHOOTING

SAFETY PRECAUTIONS

1. To ensure normal and safety operation of the electric pump, read the manual carefully before use.
   
2. The electric pump should have reliable grounding to prevent short circuit; for safety, leakage protection switch should equipped and be careful no to wet the power plug; socket should be connected in damp - proof area.
   
3. Do not touch the electric pump while working; do not wash, swim near working area or let livestock into the water to avoid accidents.
   
4. Avoid splashing pressured water to the electric pump as well as prevent the pump immersed by water.
   
5. Keep the pump in ventilation.
   
6. In case ambient temperature is lower than 4°C or the pump is not used for a long time, empty liquid the pipeline system to avoid ice cracking of the pump chamber.
   Do not operate the pump for a long time without water in it.
   
7. The pumped liquid maybe hot and under high pressure, before moving and demounting the bump, valves in both sides of the bump should be turned off first and then empty liquids in the pump and pipelines so as not to be scalded.
   
8. Do not transfer any inflammable, explosive or gasified liquids that beyond the stipulation.
   
9. Ensure the pump will not be accidently turned on while installing and maintaining; if not used for a long time, cut off the power first and then turn off valves in inlet and outlet of the pump.
   
10. Power supply should be in accordance with the voltage stated in the nameplate. If not used for a long time, put the pump in dry, ventilated and cool place under room temperature.
