The green diode (pos. 10) indicates normal pump operation.
The switch unit contains the electronic as well as the terminal block for power
supply and pump motor. The signal/operating elements at the switchbox cover
are (Fig. 2)
●
Yellow LED: Mains power is on, the pump is on ready standby, (pos. 9)
●
Green LED: Pump runs, (pos. 10)

Red LED:
●
Reset button: After fault rectification the reset button (pos. 8) must be kept
pushed until the system is fully pressurized. This is also valid for renewed
start-up, otherwise the pump will again fail due to insufficient system
pressure.

Siting/Installation
5.1 Installation
For installation and mounting requirements refer to the pump installation and
operating instructions.
The arrow at the housing indicates direction of flow.
The WILO-Fluidcontrol must only be mounted into a vertically run discharge
pipe.
●
The WILO-Fluidcontrol to be screwed onto the discharge port of the pump
using
suitable connecting fittings, to be sealed with hemp or Teflon band.
●
If the water column between pump and highest outlet tap exceeds 15 m,
the unit must be installed at a higher level in the discharge pipe ensuring
a maximum vertical head onto the unit of not more than 15 m. In such
case no outlet tap must be located at a level below that of the WILO-
Fluidcontrol (Fig. 3).
●
In order to avoid noise transmission from the pump onto the pipe system
it is recommended to provide and install a flexible connector at the
discharge side of theWILO-Fluidcontrol.
