5- START UP / SHUT DOWN

5.1- Preparation

5.1.1- Venting and priming

• Make sure that the  pump and suction pipes are completely filled up with water. There is no problem 

for the pumps which have positive suction head. If there is a valve on suction line, it must be opened 

and air taps are loosened to enable the water replaces air in the pump, until it is completely full with 

water.

• If there is a foot valve on the suction line, the air should be emptied out.

• If the system has a vacuum pump, water is brought up in the rising pipe and filled up the pump 

through this vacuum pump. When water is risen up to the highest point then the pump is started 

up.

Make sure the pump never runs dry.

5.1.2- Checking the direction of rotation

• ECO SNM type pumps rotate in clockwise when it is looked from coupling to the pump. This direction 

is already indicated on the pump nameplate by an arrow. Check this by switching the pump on, then 

off again immediately. Fit the coupling guard back in place if you took it out.

5.2-  Start Up The Pump

• Check if the shut off valve in the suction line is open and the shut off valve in discharge line is closed.

• Switch on the circuit breaker and run the motor.

• Wait until the motor reaches the full speed (on star-delta running motors wait until it switches on 

delta).

• Open the discharge valve slowly while watching the ampermeter on the control panel (if the discharge 

line is empty do not turn on the valve fully open on first start up. Turn it on slowly to maintain the 

value on the ampermeter is under the rated current value of the motor).

• When the valve is if fully open, check the pressure on the manometer and see it is the same with 

the duty point pressure. If the pressure on the pressure gauge is lower than duty point pressure brings 

them to the duty point value by slightly closing the valve. If it is higher value, check your installation, 

especially geometric height again.

The pump should be shut down at once and the trouble should be corrected if the pump 

is running at its rated speed and found any of the following faults:

ATTENTION

ATTENTION

• Pump doesn’t deliver any water,

• Pump doesn’t deliver enough water,

• Flow is going down,

• Discharge pressure is not enough,

• Driver overloaded,

• Vibration on pump,

• High noise level,
