The integrated macerator pump then grinds the wastewater and pumps it to the discharge, up to 3 m vertically and 30 m horizontally. In addition, according to SFA, the electric marine toilet Sanimarin 31 makes it easy to replace a manual-pump toilet.\u003c\/p\u003e\n\u003ch3\u003eWhat happens if I choose the No control variant?\u003c\/h3\u003e\u003cp\u003eBecause the No control variant is the toilet only, you need one of SFA's controls to operate it (Comfort, Premium or Luxe). You choose it separately. You can add it from the controls page or simply choose a variant that already includes one.\u003c\/p\u003e\n\u003ch3\u003eCan I fit the Premium control on the bowl of the Sanimarin 31?\u003c\/h3\u003e\u003cp\u003eNo. SFA allows the Premium push button on the bowl in every model except the Sanimarin 31. So on this model you must fit it away from the bowl but within easy reach of it, as the manual asks. The other two controls also need a different mounting: Comfort, a Ø 50 mm hole, and the Luxe keypad, an 88 × 48 mm cut-out.\u003c\/p\u003e\n\u003ch3\u003eCan I fit the electric marine toilet Sanimarin 31 below the waterline?\u003c\/h3\u003e\u003cp\u003eSFA covers that case with one condition. You must raise the pipe at least 50 cm above the waterline, fit an anti-siphon valve at the highest point and then run it down to the 3-way valve. The vented loop must also sit 50 cm or more above that line.\u003c\/p\u003e\n\u003ch3\u003e12 V or 24 V, and how much battery does it use?\u003c\/h3\u003e\u003cp\u003eChoose the variant that matches your boat's voltage. As for power, the motor is 300 W at 12 V and 360 W at 24 V. With Premium or Luxe, an ECO cycle uses 0.056 Ah at 12 V and 0.032 Ah at 24 V. A NORMAL one uses 0.105 Ah and 0.060 Ah.
