VEVOR Deep Well Submersible Pump
OPERATION
The electronic controller orders the automatic start and stop of the water pump when opening or closing any tap or valve of the system. The controller can keep a constant pressure and water flow in the system as long as any tap in the system is open during the pump’s operation.
CAUTION
The electronic controller can be used either for drinking water or non-
drinking water systems. In installations where both types of water are
present, make sure that drinking water is not mixed with non-drinking one.

INSTALLATION OF THE PRESSURE GAUGE(Fig.1)
The pressure gauge is provided with an O-ring, two fixing screws, and a screw cap. The pressure gauge can be mounted on any side of the controller by introducing the cylindrical connector with the O-ring into the hole in the body of the device and fixing it by means of the two supplied screws. The screw-tap is to be located on the opposite side’s pressure gauge vent (without an O-ring or Teflon).
HYDRAULIC CONNECTION(Fig.2)
Before proceeding with the hydraulic connection, it is essential to prime
the pump correctly. The controller should be installed always in a vertical
position, thus connecting the inlet opening(male 1″)directly to the pump
outlet and the lateral outlet(male 1″) to the network. Avoid outlet non-return
valves. The following accessories are recommended: Flexible with a
disassembling link for network connection, protecting the set from possible
flexion charges and vibrations. Ball valve which permits the isolation of the
pump from installation.
ATTENTION
The water column between the pump and the highest point of use shall not
exceed 15m for model DSK-2 and the pumps should supply a minimum pressure of
2.5 bar. In the case of using the control in points between 15 and 30m in
height, you are suggested to use model DSK-2.1. The adjustment of the starting
pressure is made by the screw placed at the top of the control (Fig.5 ) Read
the indicated pressure shown in the pressure gauge when the pump starts and
perform on the screw according to the wished side ( Pressure adjusting must be
per- formed by professionals). As per standards the starting pressure should
be 0.2 bar higher than the manometric one, and the pump will have to give at
least a pressure bar higher than the adjusted one, Example: This operation
only adjusts the starting pressure, not the working pressure which only
depends on the pump feature. It will be easier to proceed with the adjustment
if a tap of the installation is opened, which will reduce the internal
pressure of the control.
ELECTRIC CONNECTION (Fig.3)
Check the power supply to be~220V-240V, First disconnect the power supply,
then dismount the cover of the electronic circuit and make the connections as
per the diagram on a plate. The controller can be also used for three-phase or
single-phase pumps with intensities higher than 10A by means of an auxiliary
contact. In this case, the connections will have to be made according to the
scheme in Fig
WARNING
Bad connections may soil the electronic circuit
STARTING
- Be sure that the pump is correctly primed, and then gently open the tap.
- Connect the controller to the electric supply. The tension LED will light (POWER)
- The pump starts working automatically and within a period of 20-25seconds, the pressure gauge will reach approximately the maximum pressure provided by the pump.
- During its working, the corresponding LED(ON) will be on.
- Close the tap indicated on point After 7-9 seconds the pump will stop. The tension LED (POWER) will be the only one to remain on.
- Any problem after this procedure will be due to defective pump priming.
POSSIBLE PROBLEMS
- The pump doesn’t stop:
- Water leakage higher than 1.21/min at some point—check the system, the tap, etc.
- The manual start switch (RESET) is blocked—press it several times. Consult your dealer if the problem persists.
- Breakdown on the electronic board—proceed to its substitution
- Incorrect electric connection on electronic board—check the connections according to Fig.3.
- The pump doesn’t start:
- Not enough water supply, the security system has been activated and the LED (FAILURE) is on—check the water supply and restart the pump through the reset switch(RESET.
- Pump is blocked:
- LED (FAILURE) is on and the security system is activated. When we act on the manual start switch (RESET)the LED (ON)is activated but the pump doesn’t work—consult your dealer.
- Failure in the electronic circuit—switch off the power supply, wait a few seconds, and turn it on again. If the pump doesn’t start immediately then replace the circuit.
- No electrical supply—check the proper electric feeding. The tension LED (POWER) should be on.
- Not enough pump pressure—the security system has been activated and the corresponding LED (FAILURE) is on. Check that the pump pressure is 0.8 bar higher than the starting pressure of the controller.
- Air in the pump aspiration—the pressure gauge will indicate a pressure lower than the nominal or constant oscillations. The security system will act by stopping the pump and the LED (FAILURE) will be on. Check the sealing of the connections and O-ring of the aspiration conduct.
- The pump starts and stops repeatedly:
- Small leakage at some point of the installation—verify possible tap of tank leakages and repair them.
