3.8.1 CENTRALISED SYSTEM - FRESH WATER

3.8.1.1 - Hydraulic system

The TECMA's toilet flushing cycles use the tank fresh water.
The solenoid valve can be integrated in the toilet, directly connected to the inlet/nozzle via the
supplied black rubber pipe. Alternatively, it can be mounted in the fresh water system (the one that
serves sinks, showers, and other utilities). When the toilet is used, the control panel opens the
solenoid valve through the control unit. The water is supplied via the autoclave, which pressurises
the entire hydraulic system on board. Diagram in section 8.5.
WARNING: The recommended system operating pressure is equal to 3 bar
WARNING: Keep the filters of every solenoid valve clean.

The autoclave is always live regardless of the sanitary system used. The "before use" button opens
the solenoid valve, whilst the "after use" button starts a program that opens the solenoid valve, then
it activates the pump and lastly activates the solenoid valve again for the final rinse.
3.8.1.3 – 110V/230V Electrical system
Tecma products with a 110V/230V motor have a plug, which must be connected to the power supply.
