1General
1.0 Description
The Exalto toilet type Mariner 50 is a quiet electric macerating marine toilet with integrated
complete electronic flushing program(s). The toilet comes with a white porcelain bowl, white
coated wooden seat and cover, a control panel c/w wiring loom with “plug and play” connectors, a
solenoid valve in the water supply line and a liquid level switch for installation in the waste tank.
The pump is made of strong ABS with stainless steel cutters which makes the toilet suitable for
both fresh and salt water. The pump is located inside the bowl, giving the toilet a smooth look and
making it easy to clean.
1.1 Operation
By simply pressing one of the two buttons on the control panel, the flushing program is started. At
first, a quantity of water is allowed into the bowl. Then the powerful high speed pump with large
diameter impeller breaks down the organic residues and pumps it, together with the water in the
bowl, directly overboard or into the holding tank. The complete program takes 12 or 29 seconds,
subject to selected program.
Flushing program:
1.2 Conditions for optimum performance
The toilet was designed for grinding and pumping organic waste and normal toilet paper; putting
other object/fluids into the toilet may cause damage. The complete program is time-dependant. As
a result of that, a lower power supply will effect the pump action, reducing the capacity. A
deviation of 10% or more will effect the performance substantially and the life span of the toilet
considerably.

2.0 Connections discharge side
The toilet is supplied both with a short rubber pipe of 40/50 x 140 mm and a rubber non-return
valve of 40/50 x 135 mm. One of them is to be fitted in the discharge line. With installations above
the water line and discharge directly overboard, there is no need for the non-return valve to be
fitted. With all other applications as shown on page 6, it is advised to fit the non-return valve in the
discharge line.
2.1 Pump capacity in relation with discharge head
The graph shows the relation between the pump
capacity and the discharge head; the pump
capacity is reduced when the discharge head
goes up. The diameters of the discharge lines are
not to be reduced! The diameter of the pump
discharge connection (38 mm) is to be used
throughout the complete discharge piping
system. Reduction of the diameter will reduce
the pump capacity.
2.2 Connections of water supply
The toilet needs to be connected to a pressurised water system for flushing. The actual pressure in
the water supply line will effect the quantity of water used during a complete program. With a
higher water pressure, more water will be used when flushing the toilet; with a lower water
pressure, less water will be used. With insufficient water pressure, optimum performance of the
toilet cannot be guaranteed. The required water pressure before the solenoid is to be no less than
1 bar and no more than 2 bar.
As a standard, the toilet has a built-in solenoid in the water supply line. The connections of the
valve housing of this solenoid are ½” B.S.P. To ensure sufficient supply of water, the inside diameter
of the water supply line is to be no less than 12 mm (½”).
When seawater is used to flush the toilet, an inlet filter is to be fitted in the suction line of the
seawater pump, to prevent debris to enter the system and the solenoid valve and obstruct the
valve when closing. When a separate pump is used (electrically connected to the power supply of
the solenoid valve) instead of a pressurised system, a foot valve is to be fitted in the discharge side,
directly after the pump. This valve will keep the water supply line to the toilet full, resulting in
immediate water supply to the toilet after the program is started. Not fitting this foot valve may
result in a delay between the starting of the program and the start of the actual water supply to the
toilet. This will result in insufficient water supplied to the toilet and a satisfactory performance
cannot be guaranteed.

3 Installation
3.0 Foundation
The toilet is to be fitted on a foundation of sufficient strength. A weak foundation may bend and
cause breaking of the bowl; it may also increase the noise of pump action.
3.1 Installation of the toilet
In case the toilet is located close to the ships wall, it is advised to install the piping system and the
electrical wiring before the toilet is actually fitted. The toilet can be secured to the foundation by
using the stainless steel bracket supplied; a dimensional sketch of the bracket is shown below.
•The location of the toilet is to be
determined first. This location is
to be marked on
the foundation
and the dimensions given
below will allow you to
do so quickly and
easily.
•Secure the bracket to the
foundation.
•Place the toilet over
the bracket and secure it,
using the two stainless
steel M6 bolts and the two
white plastic rings as supplied.
When fitting the toilet, the
position of the two securing holes
in the sides of the toilet should
match the (M6) threaded
holes in the vertical parts of the bracket. To avoid breaking of the bowl, it is important to
prevent direct contact between the stainless steel and the porcelain, using the white
plastic rings under the bolt’s head. For the same risk of breakage, the M6 bolts are not to be
secured too tight.
•After tightening, the white caps supplied can be pushed over the head of the bolts, to
cover them.

3.2 Installation of the control panel
•Cut a rectangular hole of 56 x 120 mm in the ships wall, at an easy accessible location
•Remove the bezel from the control panel by sliding it upwards
•Rotate the panel 90° and insert it from behind into the hole
•Secure the control panel with screws or bolts and nuts
•Slide the bezel back into place
3.3 Installation of the reverse rotation switch
•Cut a rectangular hole of 22 x 30 mm in the ships wall or at another location
•Disconnect the wires form the switch; check the actual location of the wires on the
terminals of the switch as shown on page 8 or make a note of the actual location of each
wire on the switch for repositioning after installation of the switch
•Insert the wires from behind into the hole
•Re-connect the wires to the switch in the original positions
•Push the switch into the hole
3.4 Installation of the level switch
A (high) level switch is part of the standard scope of supply of the
toilet and is to be fitted in the waste tank. A visual alarm on the
control panel will indicate that the tank is full; the middle icon on
the control panel will be illuminated.
The level switch works on air pressure; there are no moving parts in
the tank that could effect the working of it. The electric parts of the
switch are located outside the tank in a rubber housing and is
connected to the rubber pipe in the tank by means of a flexible
tubing.
•Install a short pipe with an I.D. of 39 mm on the top of the tank
•Insert the rubber adapter into this pipe
•Push the rubber pipe into the rubber adapter

5Operation
5.0 Flushing and pumping out
The operation of the toilet is very easy. By simply pressing one of the two buttons (see pos. 5.1) on
the control panel, the flushing program will be started. The solenoid will be opened and water will
flow into the bowl. After a few seconds, the powerful centrifugal macerating pump will be started
to break down the waste and pump out the waste together with the water in the bowl. The
complete program will take 12-29 seconds.
5.1 Selecting water quantity (“ECOFLUSH” or “FULLFLUSH”)
The program offers the choice to flush the toilet with two water quantities. The two buttons on the
control panel offer the choice to flush with 3.4 – 6.2 ltrs of water. The choice of program may be
subject to availability of water.
When pressing the left button (ECOFLUSH) on the
control panel, the shorter programs will be started
and 3.4, 3.8, 4.2 or 4.9 ltrs of water will be used.
When pressing the right button (FULLFLUSH) on the control
panel, the longer programs will be started and 4.7, 4.9, 5.3 or
6.2 ltrs of water will be used.
5.2 Emergency operation
This toilet is equipped with an emergency button. With this button the pump can be activated to
empty the bowl without allowing water into the bowl first. This emergency operation can be used
when the water supply to the toilet is interrupted. When pouring water into the bowl by hand, the
toilet can still be used.
5.3 Reverse rotation
This toilet is equipped with a reverse rotation button. This button will allow you to reverse the
rotation of the pump. This may come handy in case the pump is blocked as a result of articles,
other than those that the toilet was designed for, being put into the toilet. By pressing this button,
the rotation of the pump is reversed and the debris that blocked the pump will be returned to the
bowl allowing you to remove it without taking the toilet apart. Test run the toilet again with just
water to make sure all debris has been pumped out.

6 Maintenance
6.0 Cleaning of the toilet
To clean the toilet, no special cleaners are needed. Standard available cleaners will do the job. Do
not use any cleaners on the seat and cover that may cause scratching of the surface.
6.1 Removing scale deposits
To remove scale deposits, normal household vinegar can be used. Pour the vinegar into the bowl,
leave it there for a few hours and pump it out by operating the toilet several times or poor a bucket
of water into the bowl and pump it all out with the emergency button.
6.2 Cleaning the toilet after use on salt water
This toilet is suitable for the use on salt water. However, after being used on salt water for a few
weeks, it is advised to flush the toilet with fresh water a few times.
6.3 Protection against freezing
To protect the toilet against freezing, salt or cooling fluid should be added to the flushing water (or
put into the bowl) and flushed a few times. Do not put anti-freeze in the toilet! The supply- and
discharge lines should be drained completely for optimum protection.
