INSTALLATION
Notice:
• Do not install the pump in the sunbaked or wet place.
• Install the pump to near the water source as short as possible to have a shortest suction pipe and

• Position the pump using the brackets.
• Install the pump in dry and ventilated place to ensure safe operation.
• Try to reduce the bend in pipe circuit as you can, the gradient should less than 2%.
• The connection of pipe circuit should be water-tight, the pipes should be supported separately.
• It's appreciated to install a vacuum meter and pressure gauge in the suction and discharge to obser-
ve the situation of operation.

ELECTRIC CONNECTION

Danger:
• Ensure the voltage (V), frequency (Hz), phase (PH) is conform with the ones marked on the label. When
the Voltage 10%, it will make the inset thermal protector operate and the motor stop operating.
• Pump should be reliably earthed and with leakage protection switch.
• The cord should meet the requirements of current.
• Make sure the correct electric connection according to the wiring diagram.
START, OPERATION AND STOP THE PUMP
Warning:
• Dry operation is prohibited to avoid burning of mechanical seal.
• It could rotate freely from the fan cover by screw driver.
• Turn on the pump, it should be clockwise view from the fan cover.
• Fill water in the pump from the prime plug.

• Close the discharge valve before stopping the pump and power.
MAINTENANCE
Notice:
• It is prohibited to start the pump frequently, it should disconnect the switch when the power supply is
suddenly interrupt.
• It is not allowed to use the suction valve to adjust flow.
