1. The pump should be installed on a metal frame or board 10 mm above the foot of the motor. The motor should be connected to a reliable ground to prevent electric shock. 2. Before starting the pump, you should check whether the motor is damp, the circuit is intact, the mechanical part is stuck or loose, if any abnormal phenomenon should be excluded. 3. The pump should be the appropriate diameter of the glue pipe, one end of the suction pipe connected to the end of the valve, the other end of the pump inlet tight, and then from the pump outlet to the pump filled with diversion. At the same time, unscrew the exhaust bolts, drain the air and then tighten the bolts. 4. Connect the power cord, should use 4 square millimeter is appropriate, and 10A single-phase knife switch connected to the power of the main line, should not be directly inserted into the lamp. Install the circuit should pay attention to safety, the connection of the wires should be reliable, should avoid wrapping around the excess wire to prevent electric shock. 5. After the power is turned on, the motor should start within 3 seconds, if it can not start, immediately cut off the power and repair the line. 6. When pump is pumping under low voltage and low lift condition, pay attention to the running status of the motor. If the temperature rises to hot, it will automatically cut off the power and stop working. After the temperature drops, the motor will start up automatically. 7. The pump adopts the skeleton oil seal to seal. If it is used for a long time, the wear is serious and the pump is not on the water, the new one should be replaced promptly. 8. The motor should have protective devices, shall not work in the sun and rain environment. Long-term use of the pump, the pump drained water should be drained, and painted a little butter or oil on its surface to prevent rust.
