• The flow paths to and from the system are not blocked.

• The power supply connections are as specified in the Electrical Drawings.

• Protective earth is connected.

• Cut off the small rubber tip on top of the manometer. However, do not remove the

black rubber part.

• The communication connections are as specified in the Electrical Drawings.

• All internal valves are set to Open/Run position.

• Power up the system by switching on the automatic fuse. Observe the start-up of

the water monitoring unit and the sensor modules.

• Set the IP-address following section 4.2.5.

• Verify that all functions described in the communication protocol found in the

installation manual are working.

• Set the clock and date on the HMI display by pressing a random area of the screen

for 5 seconds. A popup menu will appear. Choose Show System Settings and go to

Time. Set the time and date and return to the Home Page.

• Open the flow regulator valve inside the WMRTU cabinet to the middle position

(i.e. turn the valve to the outer position, then turn the valve 4 turns in the opposite

direction).

• Start sampling by pressing the RUN button in at the bottom right corner of the

home page on the WMRTU system.

• The WMRTU pressure setting is delivered pre-adjusted. If flow alarm occurs

during initial start-up, it indicates that the installation requires more pressure to

trigger the flow sensor. This can be done by increasing the pressure on the pressure

reducing valve. Please look at the manometer to ensure that the maximum

allowable pressure is not exceeded. Observe that a flow is established, and no flow

alarm occurs.

ATTENTION

• The suction line must not be blocked when the pump is running. The pump will be

damaged if the suction line is blocked.

• Do not run pump dry. Avoid air in the sampling to prevent the risk of air lock

leading to flow alarm and damage of the pump.

• Pay attention to the temperature of the pump. Time to cool down can be needed

prior to attempting restart.
