6.2 Use and Maintenance

2.1 After setting up the pump, check the insulation resistance again and

make sure there is no damage to the cable. Turn the pump on to test after

making sure everything is ok. Check to see if the voltage and current on

the control box comply with that on the specified technical parameter of

the pump. After checking the flow rate and there is no vibration and noise,

the unit can be used.

2.2 After the pump has run for 5 hours first time, the pump should be shut

down immediately to check the hot insulation resistance. It should not be

less than 0.5M

2.3 The time interval between shut down and restart is better to be 30 minutes

to prevent damage to the pump due to the incomplete backflow. The

startup times in 24 hours are better to be less than 10 times.

2.4 After normal operation, regular inspection of the voltage, working current

and insulation resistance may extend the pump's service life. If any of the

situations listed below exist, immediately shut the pump down for

troubleshooting.

(1)

The current exceeds 20% of the rate current under rated head and

flow rate.

(2)

When the dynamic water level is below the inlet joint, it will result in

water pumped intermittently or running idly.

(3)

Violent vibration of the pump and pipeline.

(4)

The voltage is too low.

(5)

Fuse in the control box is burned out.

(6)

The hot insulation resistance for motor to the earth is less than 0.5M

(7)

After the pump has been working for a year, or after it has been

submerged for two years, take the pump out to clear sundries or replace

worn parts.
