 A bypass regulator is provided to set the pump
pressure (starting from VC 1200).
 For consumers with a maximum permissible oper-
ating pressure below the maximum pressure of the
pump, use a safety valve for protection. This safety
valve must be installed in the flow of the device.
1. To reduce the pump pressure, turn the bypass adjustment
wheel anticlockwise until the maximum permitted pressure
for the external consumer is reached.
Monitor the display on the manometer for this.
2. To increase the pump pressure, turn the bypass adjustment
wheel clockwise until the required pressure for the external
consumer is reached.
