Vetus Electric Marine Toilet SMTO2 — Installation & User Manual

Technical Data

Control panel: 72 (2 13/16") square, cut-out ø 57 (2 1/4"), 4 × ø 4,5 (3/16") fixing holes; toilet dimensions in the drawing in the PDF.

• Only for faeces and toilet paper: no cotton wool, tampons, sanitary towels, condoms, hair, oil or other liquids.
• Never put your hands in the bowl outlet: the macerator blades are not covered. Never work on the electrical system while it is live. Keep rubber gloves on board for cleaning.

Installation

• Install to local regulations: in some areas pumping waste straight overboard is not permitted.
• Mount on a floor strong enough to avoid point loads that could split the bowl (reinforce with multiplex if needed); use the toilet as a template and the fasteners supplied.
• Outlet: hose connector Q on the bowl outlet with clamp H; 19 mm ID drain hose (e.g. VETUS no-smell sanitary hose) with clamps. The connector turns to route the hose left, right, down or up; its bend can be cut off to run the drain upwards.
• Water supply: ball valve with 3/4" connection, always accessible. A pressure system must give at least 1.5 bar (22 psi); otherwise, or with outside water, fit a supply pump of at least 10 litres/minute (2.2 Imp.Gal/min; 2.7 US Gal/min). Filter outside water well.
• If the toilet is below, or less than 40 cm (16") above, the waterline, fit an air-relief valve at the highest point of the outlet against siphoning.
• Electrical: check the motor type plate voltage; batteries with enough capacity; switch and fuse in the + wire; wire at least 6 mm2 (12 V) or 4 mm2 (24 V). Red +, black −.
• Control panel: fit the build-in flange with packing in the wall, connect the flat cables, cover the plug connection and click the panel in with its O-ring.
• Test: open the supply valve fully, run a cycle, then run one with a few pieces of toilet paper, and check all connections for leaks.

Use and Maintenance

• Supply ball valve open. ECO button: short flush (1,2 litres), about 10 seconds. NORMAL button: long flush (2,2 litres), about 20 seconds. Each cycle is a flushing phase (magnetic valve) then a pumping phase (macerator).
• Close the ball valve after use; rinse with clean water a few times if the toilet has not been used for a while.
• Winter: close the water supply, pump the bowl empty by holding the pump-symbol button, pour about 2 litres of antifreeze into the bowl and drain the pipes. Antifreeze is toxic: never discharge it overboard.
• Descale at least twice a year: close the supply, pump empty, leave about 1 litre of vinegar or scale remover in the bowl for some hours, then run several cycles. No sodium-based unblockers or solvents. Rinse with fresh water now and then if flushing with seawater.
