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 prevent from reducing the suction.
• 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 observe 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.
• Turn on the pump, open the discharge valve to set the flow and
discharge pressure to the required data.
• 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.
• When the water is insufficient, it should stop the pump.
• If there is some abnormal noise, please stop the pump and check.
• If the pump is not use for long time or stop in low temperature, wa-
ter should be drained to avoid damaging the pump body as freezing.
