Commissioning

General preparations and control measures

Check that all on-site wiring has been performed correctly, in particular the earthing, prior to the initial start-up.

Check that the pipes joints are not under stress.

Fill the system and subject it to a visual inspection for leakages.

Open the shut-off devices at the pumps and in the suction and pressure piping.

Open the pump venting screws and fill the pumps slowly with water to allow the air to escape completely.

Commissioning the system

After all the preparations and checks have been made, switch on the main switch and set the control system to automatic mode. The pressure sensor measures the pressure at hand and transmits a corresponding current signal to the control device. If the pressure is less than the set start-up pressure, depending on the parameter settings and the control mode, it first switches on the base-load pump and, as required, the peak-load pump(s) until the consumer pipes

are filled with water and the set pressure has built up.

Decommissioning the system

If the pressure-boosting system has to be taken out of service for maintenance, repairs or other measures, proceed as follows:

Switch off the voltage supply and secure it against being switched on again by unauthorised persons.

Close the shut-off devices upstream and downstream of the system.

Shut off the diaphragm pressure vessel at the throughflow fitting and drain it.

Drain the system completely if necessary.

Consulting guide

Inlet pressure

The maximum inlet pressure (see Technical data) is to be observed for the system configuration. The maximum permissible inlet pressure is calculated from the maximum operating pressure of the system minus the maximum pump delivery head at Q = 0

Pressure reducer

Fluctuating inlet pressure is compensated by the speed control integrated into each single pump as long as the pressure fluctuation is not greater than the difference between the setpoint pressure value and the zero-delivery head of the single pump at minimum speed. If the pressure fluctuation is greater, a pressure reducing valve must be installed upstream of the system.

Volume flow

Up to 240 m3/h (66 l/s) system configuration according to DIN 1988 (EN 806); with standby pump up to 320 m3/h (88 l/s) in the event of operation of the pump as an additional peak-load unit

Residual-current devices

When installing residual-current-operated protection switches in conjunction with frequency converters, bear in mind that only universal-current-sensitive residual-current-operated protection switches in accordance with DIN/VDE 0664 are to be fitted.

Wilo-WMS low-water cut-out switchgear

The series Helix VE pump being used is already equipped with an integrated dry-running detection as safety equipment for the pump. The installation of a low-water cut-out switchgear is required if the pressure boosting systems are connected directly to a public mains power supply; this prevents the inlet pressure in the mains supply line from dropping to values below 1.0 bar. Please order directly when ordering the pressure boosting system. The WMS will then be installed in the pressure boosting system by Wilo, electrically wired and fully tested at the final functional test.

Standards/directives

The overall system conforms with the requirements of

  • DIN 1988 Part 5
  • DIN 1988 Part 6* (**)

* The specifications in DIN 1988 (EN 806) and of the water-supply companies are to be observed. Regarding the electrical components, the system conforms with the requirements of

  • VDE 0100 Part 430/Part 540
  • VDE 0110 Part 1/Part 2
  • VDE 0660 Part 101/Part 107 and
  • DIN 40719/IEC 754

Always observe the specifications in DIN 1988 (EN 806) when using and operating the pressure boosting system.(**) That does not apply to fire extinguishing systems in accordance with DIN 14462. Please request these separately.
