DIMENSIONAL DRAWING

INSTALLATION INSTRUCTIONS

Your toilet is just one part of a system. Correct installation of the whole system is essential if you want the toilet to perform properly, operate reliably and safely, and give satisfactory length of life.

The seat and id is delivered boxed and unfitted for ts protection.
Key numbers, e.g. (Key 31′) are references to the exploded view diagram on the back page.

LOCATION

Select a location that will give sufficient clearance all round and above the bowl.
The mounting surface must be flat, rigid and strong enough to support a man’s weight and should be at least 2″ (50mm) wider and 2″ (50mm) deeper than the base of the tolet.
You will need sufficient clearance below the mounting surface to be able to secure the mounting bolts, and to be able to remove them for maintenance.
ffer up the seat and id to the bowl. They should be able to swing up and over, so that they will not fall forward when the craft heels or pitches. When they are swung over they must be supported so that the hinges are not strained. Remove the seat and lid and put them aside until the installation is complete.

MOUNTING

You will need:

4x 1%’ (6mm) diameter stainless steel bolts of length to suit the thickness of the mounting surface.
4stainless steel nuts, preferably self-locking. If you do not use self-locking nuts you will need some nut-locking compound.
4 plastic and 4 stainless steel 1% (6mm) washers.
Atube of white silicone sealant
Offer up the toilet in the selected position and, using the holes in the base as a guide, mark the positions for the 4 bolt holes on the mounting surface. Remove the toilet and drill 4 vertical holes of 5/16 (8mm) diameter through the mounting surface.

Now complete all of the rest of the installation before you secure the bowl.

THROUGH HULL FITTINGS

You will need:

*/,” 19mm bore seacock for the Rinse pump and, if you are discharging the waste over board, a 1%4″ 38mm bore seacock for the waste outlet.
Follow the seacock manufacturer’s own instructions concerning materials and methods of installation.
Ensure the inlet seacock is positioned where it will be below the waterline at all times when the craft is underway, and also ensure that any other outlet seacock is both aft of, and higher than, the inlet seacock.

HAZARD RISK: Through Hull fittings.

FOLLOW THESE INSTRUCTIONS!

If the installation of the toilet results in it being connected to any through-hull fitting that may possibly be below the waterline at any time, whether when the craft is at rest, underway and heeling or rolling or pitching, you must install the toilet in accordance with these installation instructions. If you do not, water may flood in, causing the craft to sink, which may result in loss of life.

HAZARD RISK: ACCIDENTAL DAMAGE.

USE SEACOCKS!

If the toilet is connected to any through-hull fittings and if the toilet or pipework is damaged, water may flood in causing the craft to sink, which may result in loss of life Therefore, if you are making connections between the toilet and any through-hull fittings that may possibly be below the waterline at any time, full bore seacocks must be fitted to those hull fittings, to allow them to be shut off.

The seacocks must also be positioned where they are easily accessible to all users of the toilet. If, for any reason, itis not possible to do this, then secondary bore marine quality valves must be fitted to the hoses where they are easily accessible.

CAUTION! Use lever operated, full bore marine seacocks and valves. The use of screw-down gate valves is not recommended.

PIPEWORK – SELECTION OF CORRECT METHOD

‘You must select the correct method for the inlet pipework from 2 options and for the outlet pipework from 4 options, according to whether the toilet is above or below the waterline, and to whether it discharges the waste overboard o into an on-board holding tank

HAZARD RISK: BOWL RIM BELOW WATERLINE.

USE VENTED LOOPS!

If the toilet is connected to any through-hull fittings, and if the rim of the bowl falls Below the waterline, water may flood in causing the craft to sink, which may resultin loss of life.

Therefore, if the rim of the toilet is less than 8 (20cm) above the waterline when the craft is at rest, or if there is any possibility that the rim of the bowl may be below the waterline atany time, a ventilated anti-syphon loop must be fitted in any pipework connected to a through-hull fitting, irrespective of whether inlet or outlet

SPECIAL NOTE 1: The smaller bore inlet pipework is more hazardous than the larger outlet pipework Unless there is a ventilated anti-syphon loop in the inlet pipework, water will flow into the bowl whenever both the inlet seacock is open and the rim of the bowl is below the actual waterline.

SPECIAL NOTE 2: Making aloo in the hose without fitting a vent may be just as hazardous as no loop atoll, because water may syphon over a loop. It is the vent that actually prevents the syphon

HAZARD RISK: PIPEWORK BECOMES LOOSE.

USE HOSE CLIPS!

If the toilet is connected to any through-hull fittings and if the pipework becomes disconnected, either from a through-hullfitting or seacock, or from the toilet or any secondary valve, water may flood in and cause the craft to sink, which may result in loss oflfe.

Therefore the ends of all flexible hoses fitted directly or indirectly between the toilet and any through-hull fitting that may possibly be below the waterline at any time, must be secured to the hose tails to which they are connected, using two stainless steel worm-drive hose clips.

PIPEWORK – GENERAL INSTRUCTIONS FOR ALL OPTIONS

You will need:

Spiral reinforced smooth bore flexible hoses for both the %” 19mm inlet and the 1″ (38mm) outlet pipework.
Two stainless steel worm-drive hose clips for every hose tail connection.
Secure the hose runs so that the hoses cannot move and chafe, and so that they do not exert any leverage on the hose tail fitlings to which they are connected, as this may cause adjacent joints to leak.
Avoid sharp bends in the hoses as this may cause them to become kinked.
Keep all pipework runs as straight and as short as possible, avoiding rising and falling over obstructions which creates airlocks.
Ifitis difficult to fit the hose onto the hose tails of the toilet or seacocks, lubricate it with water, or soften the hose by dipping the end in hot water.
CAUTION! Do not apply flame to the hose. Do not apply flame or heat to the plastic hose A tails on the toilet, rinse pump or solenoid valve. Do not use oils, greases or synthetic lubricants. Do not apply sealing compounds to any hose connections. Do not over tighten hose clips. Any of these actions may resultin cracking or breakage of the plastic parts
Secure the ends of all hoses to the hose tails with two stainless steel worm-drive hose clips, ensuring that all inlet connections are airtight and that all the outlet connections are water tight.

FRESH WATER RINSE PIPEWORK

You will need:

A’T”piece that fits your boat’s pressurized
CAUTION! Turn off power to the water pressure system pump, and open cold water taps to de-pressurize the system. Install a T fitting in the pressurized cold water pipework near to the toilet to provide a %” (13mm) feed to the Solenoid Valve.
CAUTION! If you ever connect your water system to unregulated USA City Water supplies, you must fit or use a pressure regulator to prevent risk of flooding

SAFETY

Ensure that this instruction manual reaches the owner, skipper or operator of the craft as it contains essential safety information.
‘ON COMPLETION – CLOSE BOTH SEACOCKS

The tolet is one of the most used pieces of equipment on your boat. Correct operation of the toilet is essential for the safety and comfort of your crew and craft

Open inlet and outlet seacock (and secondary valves if fitted)
Use good quality hard or soft household toilet paper, but do not use more than necessary.
Do not put anything in the toilet unless you have eaten it first, except toilet paper.

XTI HAZARD RISK: Accidental Damage. SHUT SEACOCKS!

Ifthe toilet is connected to any through-hull fittings that are below the waterline at any time, and if the toilet or pipework is damaged, water may flood in, causing the craft to sink, which may result in loss of life.

OPERATING INSTRUCTIONS

Therefore after every usage, both seacocks (or secondary valves) must be shut. Whenever your craft is unattended, even if for only a short period of time, both seacocks (even if secondary valves are fitted) must be shut

Ensure that all users understand how to operate the toilet systems correctly and safely, including seacocks and secondary valves.
Take special care to instruct children, the elderly and vistors.

CLEANING

To clean the bowl, use any liquid or cream ceramic cleaner.
CAUTION: Do NOT use aggressive chemical agents such as Acetone or Bleach because the plastic parts may crack and the enamel coating on the seat and lid may blister.
To clean the rest of the toilet, including the seat and lid, use a non-abrasive liquid cleaner. Polish with a dry cloth only.
CAUTION: Do not use abrasive pads on any part of the toilet and do not use cream cleaners except for the bow!.
To disinfect the toilet, use a liquid disinfectant diluted in accordance with the manufacturers instructions. You may apply it to all parts of the toilet using a sponge or soft brush as necessary.

SERVICING INSTRUCTIONS

SEAFLO Deluxe Flush Electric Toilets do not normally require maintenance during the season, provided that they are winterized in the autumn.

Regularly check all fastenings for tightness and leaks.

HAZARD RISK: Leaks. REPAIR LEAKS IMMEDIATELY!

If the toilet is connected to any through-hull fittings and, if the toilet or the pipework develops a minor leak, it can suddenly become a major leak that allows water to flood in, causing the craft to sink, which may resultin loss of life. Therefore, if any leak develops you must repair it immediately.

SOLENOID VALVE

The Solenoid Valve is maintenance free.

RINSE PUMP

Please refer to the data sheet provided for the SEAFLO 43T series rinse pump.

CERAMIC SHAFT SEAL
