3.2 Solenoid valve
The Invensys solenoid valve can be integrated in the toilet, directly in the inlet hose connector (see
specification on page) or installed in the fresh water supply line.
Before installing the solenoid valve, clean the pipes (brazing or welding residues, metal chips, seal
material).
A filter inside the solenoid valve prevents failures resulting from water impurities. We recommend
cleaning the solenoid valve filter regularly. Do not force the solenoid valve when tightening it. Do
not obstruct the pilot hole at the valve outlet. The entire piping section must be free from
bottlenecks. Comply with the recommended pressure range (refer to section 7.0).
3.3 Inlet pump
Install the inlet pump in a dry and ventilated place. The pump cannot be submerged or exposed to
sprays.
Install a fuse in the power supply circuit.
The pump can be assembled horizontally as well as vertically (in this case, the pumping unit must
face downwards).
Install the filter before the pump.
Install a vent valve to prevent siphoning phenomena, especially if the toilet is installed below the
floating line
WARNING: The inlet pump must not be used as a check valve. Failure to use a vent valve
may result in flooding, loss of the property, injuries, or even death.
