POSITIONING OF THE UNIT
Maintain a minimum clearance of 50 cm from any wall of the unit. Keep the unit
away from any hot surfaces. Always operate the unit on a level, stable, clean,
fireproof and dry surface and out of the reach of children and persons of impaired
mental, sensory and intellectual functions.
The unit must be positioned in a way that the pump (pump unit, including the pump
handle and lever) and the drain plug are accessible at all times.
The mounting surface must be flat, hard and strong so that the floor can support
the weight of an adult.

Additionally, the seat and the toilet lid should be able to be tilted upwards and
outwards and they should not fall down when using the toilet. When tilted, the seat
and the toilet lid must be propped up so that the hinges are not strained.

ASSEMBLY OF THE UNIT
Prepare for assembly:
1. 4 screws with a diameter of 8 mm (5/16") made of stainless steel with a length
adapted to the thickness of the mounting surface,

2. 4 stainless steel nuts, preferably self-locking. If nuts other than self-locking
nuts are used, you must additionally use a special compound to secure the
nuts,
3. 8 large stainless steel washers with a diameter of no more than 21 mm
(13/16"),
4. A small tube of white silicone sealant.
Assembly:
1. Set the toilet in the desired position.
2. Mark the places for drilling the 4 mounting holes (using the holes in the base).
3. Remove the toilet and drill 4 vertical holes with a diameter of 9 mm in the
mounting surface.
4. Apply a coat of white silicone sealant to the outer edge of the lower base.
5. Screw on the toilet and tighten the fasteners securely. If you are not using self-
locking nuts, use a compound to secure the nuts.
HULL HARDWARE
You should prepare:
•A 19 mm (1-1/2") diameter safety valve for the flush water inlet and, if
debris is being thrown overboard, a 38 mm (1-1/2”) diameter safety valve
for the waste water outlet.
•Follow the safety valve manufacturer's instructions for materials and
installation methods.
•Make sure the inlet valve is below the waterline at all times when the vessel
is in motion, and make sure the outlet valve is positioned behind the aft
and higher than the inlet valve.
If the installation of the toilet needs to be joined with any hull connection that may be
below the waterline at any time (regardless of whether the vessel is at rest or in
motion), install the toilet in accordance with the following installation instructions:
•if connections are made between the toilet and any hull fittings that may
be below the waterline at any time, it is necessary to install valves of the
required diameter.
•These valves must be placed within easy reach of all users of the toilet. If
for any reason this is not possible, then full-size secondary valves must be
fitted to the hoses in a place where they are easily accessible.

If the toilet is connected to the hull throughfittings and the connections are
inadequately secured, when the toilet or the piping is damaged, the vessel may be
flooded, causing sinking and, consequently, loss of life.
CAUTION! Use ball valves of the required diameter. The use of screwed gate
valves is not recommended.
CONNECTING THE PIPES - CHOOSING THE METHOD
Select the correct method of connecting the inlet pipes (out of 2 options) and
connecting the outlet pipes (out of 4 options). The choice of the method depends on
whether the toilet is above or below the waterline and whether it is discharging waste
overboard or into an on-board tank.
CAUTION! If the toilet is connected to any throughfitting and the piping is
disconnected (from the throughfitting, safety valve, toilet or secondary valve),
water may overflow onto the deck and cause sinking.
The ends of all flexible hoses fitted directly or indirectly between the toilet and any
hull throughfitting joint that may be below the waterline at any time must be
secured with two clamps for stainless steel hose with worm gear.
CAUTION! Hose clips must be used!
GENERAL RULES FOR CONNECTING PIPES:
1. Secure the hoses in such a way that the hoses cannot move or rub against
anything and that they do not put any pressure on the couplings of the ends
to which they are connected, as this may cause adjacent connections to leak.
2. Avoid sharp angles that could cause the pipes to bend.
3. Keep all tubing lengths as short as possible, while still adhering to these
instructions. Unnecessary length of the inlet or outlet hose makes it difficult to
pump water into the toilet.
4. If it is difficult to attach the hose to, for example, the valves, lubricate it with
water or soften the hose by submerging its end in hot water.
CAUTION! Do not use fire to connect the plastic hose ends. Do not use oils,
greases or synthetic lubricants. Do not use sealant on any hose connections. Do
not over tighten the hose clamps. These actions may crack or break the plastic parts
of the toilet.

5. Fasten all hose ends with two stainless steel worm clamps, making sure all inlet
connections are tight and all outlet connections are watertight.
6. The outlet bend can be rotated by 360° to suit the installation. Always loosen
the 2 securing bolts, adjust the outlet bend to the required position and
retighten the 2 securing bolts before connecting the hose to it.
CAUTION! Failure to follow this procedure can cause leakage between the
inlet bend and the pump cylinder.
INLET PIPE CONNECTIONS (2 OPTIONS):
CAUTION! Always use a spiral reinforced marine hose with a smooth internal
bore of the recommended size!
I. TOILET BELOW THE WATERLINE
You should prepare:
•Reinforced spiral smooth flexible hoses for 19 mm (3/4") inlet and 38 mm
(11/2") outlet.
•Two stainless steel worm clamps for each hose end connection (4, 6 or 8).
When the toilet is installed below the waterline, appropriate anti-siphon loops are
required, both on the inlet hose (19mm, 3/4``) and on the outlet hose (38mm, 1½'').
This will prevent the water from siphoning back into the boat after using the toilet.
Install a 19 mm (3/4") ventilated loop, route the inlet hose directly from the inlet valve
to the pump inlet.

A. 19mm (3/4'') ventilated loop
B. 38mm (1'') ventilated loop
C. Height above the waterline (at all angles of heel) at least 20 cm (8'')
D. Waterline when heeling
E. Waterline
F. 38 mm (1'') outlet
G. 19mm (3/4'') inlet
1. Disconnect the hose connecting the pump inlet to the bend provided with the
toilet.
2. Rotate the inlet seal so that the bend is facing up.
3. Replace the hose with a previously prepared flexible hose of 19 mm (3/4") in
diameter and lay it down to form an antisiphon loop [A] with the highest point
at least 20 cm (8") above the highest possible waterline and install the
ventilated loop at the highest point.
4. Secure the ends of all hoses with two stainless steel worm clamps.
CAUTION! Inlet tubing with a smaller bore is more dangerous than outlet
tubing with a larger bore. If there is no ventilated anti-siphon loop in the inlet

pipeline, water will flow into the bowl both when the inlet valve is open and when
the rim of the bowl is below the actual waterline.
Setting the lever to the closed (pumping) position will restrict the flow, but the
lever MUST NOT be considered a shut-off valve. Looping the hose without a vent
can be as dangerous as not installing the loop, as water can seep through the loop.
II. TOILET ABOVE WATERLINE
You should prepare:
•19 mm (3/4") check valve.
1. Route the inlet hose by the shortest route from the inlet valve to the pump
inlet end.
2. Install a 19 mm (3/4") inline check valve next to the inlet valve.
A. Optional: 38 mm (1'') ventilated loop
B. Waterline when heeling
C. Height from drain bend to ventilated loop - at least 30 cm (12'')
D. 38 mm (1'') outlet
E. 19mm (3/4'') inlet
F. Optional: check valve
G. Outlet bend

OUTLET PIPE CONNECTIONS (4 OPTIONS):
I. TOILET BELOW THE WATERLINE AND DISCHARGING WASTE OVERBOARD
When the toilet is installed below the waterline, appropriate anti-siphon loops are
required, both on the inlet hose (19mm, 3/4``) and on the outlet hose (38mm, 1½'').
This will prevent the water from siphoning back into the boat after using the toilet.
Prepare a 38 mm (1½") ventilated loop.
A. 19mm (3/4'') anti-siphon loop
B. 38mm (1 ') anti-siphon loop
C. Height above the waterline (at all angles of heel) at least 20 cm (8'')
D. Waterline when heeling
E. Waterline
F. 38 mm (1'') outlet
G. 19mm (3/4'') inlet
Place the outlet hose to form a loop that is at least 20 cm (8") above the highest possible
waterline, and install a ventilated loop at the highest point.
II. TOILET ABOVVE THE WATERLINE AND DISCHARGING WASTE
OVERBOARD

If the toilet is to be installed above the waterline, it is recommended that the outlet
hose forms a loop to place the outlet hose about 30 cm above the outlet bend.
Prepare a 38 mm (1½") ventilated loop (optional).
A. Optional: 38 mm (1'') ventilated loop
B. Waterline when heeling
C. Height from drain bend to ventilated loop - at least 30 cm (12'')
D. 38 mm (1'') outlet
E. 19mm (3/4'') inlet
F. Optional: check valve
G. Outlet bend
Route the exhaust hose upward from the drain bend to form a loop at least 30 cm (12")
above the drain bend.
Installing a ventilated loop at the top will allow water to be retained in the base of the
toilet without the risk of it being siphoned off.
III. DISCHARGING WASTE FROM THE TOILET INTO A TANK UPPER EDGE OF
THE TANK ABOVE DRAINAGE AT ANY TIME
Prepare a 38 mm (1½") ventilated loop.

A. 38 mm (1'') ventilated loop
B. Tank vent pipes
C. Height from the top of the tank to the ventilated loop - at least 20 cm (8'')
D. Optional: 38 mm (1'') ventilated loop
E. Height from drain bend to ventilated loop - at least 30 cm (12'')
F. Drain bend
G. Top of the tank above the outlet bend at any time (option III)
H. Tank below the outlet bend (option IV)
If there is a possibility that the outlet bend will be below the top of the tank, install a
ventilated anti-siphon loop in the outlet piping so that the contents of the tank do not
flow out through the bowl.
Lay the exhaust hose so that it forms a loop that is at least 20 cm (8") above the highest
possible level that the tank can reach and install the ventilation loop at this highest
point.
IV. DRAINAGE FROM THE TOILET TO THE TANK, THE DRAIN BEND ALWAYS
ABOVE THE TOP EDGE OF THE TANK.
Prepare a 38 mm (1½") ventilated loop (optional).

A. 38 mm (1'') ventilated loop
B. Tank vent pipes
C. Height from the top of the tank to the ventilated loop - at least 20 cm (8'')
D. Optional: 38 mm (1'') ventilated loop
E. Height from drain bend to ventilated loop - at least 30 cm (12'')
F. Drain bend
G. Top of the tank above the outlet bend at any time (option III)
H. Tank below the outlet bend (option IV)
Route the exhaust hose upward from the exhaust bend to form a loop at least 30 cm
(12") higher than the exhaust bend. This will create a water seal at the valve to prevent
unpleasant odors from the toilet.
If the ventilation loop is installed on top of the hose loop, it will ensure that water can
be retained in the base of the toilet without the risk of flooding.
CAUTION! Close both valves (inlet and outlet) after installation and whenever
the toilet is not in use!
CAUTION! Whenever the toilet is not in use, move the lever to the closed
position (pumping).

3.3. Working with the device
A. Flush and drain (open position)
B. Pumping (closed position)
FIRST USE
When the toilet is being used for the first time and after longer periods of rest, some
parts of the toilet may need to be lubricated.
1. Open the inlet and outlet valves (and secondary valves if fitted).
2. Fill half the bowl with warm, fresh water.
3. Set the lever to the closed position ( ) and then pump out the warm
water.
REGULAR USE
1. Open the inlet and outlet valves (and secondary valves if fitted).
2. Before use, make sure that there is enough water in the bowl to prevent the
toilet paper from accumulating at the bottom of the bowl. If the bowl is empty,
move the lever to the open position (flush and drain) ( ) and move the
pump handle up and down until the water fills the bowl.
3. After filling the bowl with water, set the lever to the closed position (pumping
out: ).
4. For the pump to function properly and efficiently, make long, smooth
movements (with the pump handle).

5. If necessary when using the toilet, you can use the pump to pump out some of
the contents (to keep the filling of the bowl low enough for comfortable use).
6. Use good quality toilet paper. Do not use more toilet paper than necessary.
Risk of clogging the toilet!
7. After use, set the lever to the closed position (pumping: ) and pump until
the bowl is empty.
8. When the bowl is empty, set the lever back to the open position (rinse and
drain: ) and continue pumping until all contents are removed (do approx.
7-10 full movements up / down).
9. Finally, move the lever to the closed position (pumping) and make another 7-
10 pump movements to pump out all the water from the system (so that the
waste does not flow back into the toilet).
10. After using the toilet, close both valves (inlet and outlet)!
3.4. Cleaning and maintenance
a) Empty and clean the tank regularly (if this type of installation is used).
b) Use only non-corrosive cleaning agents for cleaning the surfaces.
c) Perform regular inspections of the unit checking technical fitness and any
damages.
d) Use a soft cloth for cleaning.
e) Do not use sharp and/or metal objects (e.g. wire brush or metal spatula) for
cleaning as they may damage the surface of the appliance material.
f) Do not clean the unit with acidic substances, medical products, diluent, fuel,
oil or other chemicals as this may cause damage to the unit.
CAUTION! Water in the discharge pipes tends to go back up. For this reason,
after using the toilet and emptying its contents, perform approx. 10 movements in
"flush and drain" mode and approx. 10 movements in the "pump down" mode.
CAUTION! Only toilet paper may be thrown into the toilet!
CAUTION! It is forbidden to throw into the toilet: personal
hygiene products (wet wipes, diapers, pads, tampons, cotton
buds, ear buds), building materials, medicines, needles and
syringes, hair, dental floss, wool, cigarettes or cigarette filters,
litter, foil bags, toys, condoms, chewing gum and pour fats, oils,
hot water, gasoline, solvents.

g) Do not use strong chemicals (e.g. acetone), as plastic parts may break and the
enamel coating on the seat and cover may be damaged.
h) Use any ceramic cleaner to clean the bowl.
i) Use a non-abrasive liquid cleaner to clean the rest of the toilet, including the
toilet seat and lid. Polish only with a dry cloth.
j) NOTE: Do not use abrasive cloths on any part of the toilet and do not use
creamy cleaners (except the bowl).
k) To disinfect the toilet, use a liquid disinfectant diluted according to the
manufacturer's instructions. It can be applied to all parts of the toilet using a
sponge or a soft cloth depending on your needs.
l) NOTE: Do not use thick liquid toilet cleaners or pure bleach. They can damage
the valves, gaskets, seals and the enamel coating of the toilet seat and lid.
m) Check all fasteners regularly for leakage.
CAUTION! If the toilet is connected to any throughfitting and there is a slight
leak in the toilet or in the piping, it should be repaired immediately. Even a small
leak can cause sinking. If there is any leakage, repair it immediately!
I. SERVICE AND WINTER TIME - PREPARATION
1. Flush the toilet according to the instructions for use for regular use. Make sure
that all waste has been drained and that the bowl is empty.
2. Close both bottom valves (even if secondary valves are installed).
NOTE: If the vessel spends winter in the water, close both valves as well.
3. Handheld toilets are designed to be serviced in-house. No special tools are
required.
II. MAINTENANCE - CHANGING THE SEAL
If water begins to leak around the piston at the top of the pump, the packing [items
32,33,34] is worn and must be replaced.
1. Unscrew the pump cylinder [18] with a 24 mm (15/16 ") wrench and remove
it.
2. Wrap the piston [28] with tape approx. 16 mm (5/8 ") from the handle. Grab
the plunger through the tape, unscrew the handle and remove the O-ring [25].
Remove the tape.
3. Slide the old packing assembly off the piston [keys 32, 33, 34]. Wrap tape
around the threads on top of the piston to secure the new seal and slide the
new seal assembly [32, 33, 34] onto the piston. Remove the tape from the
thread.

4. Wrap the piston [28] with tape approx. 16 mm (5/8 ") from the handle. Grab
the plunger through the tape and install the washer and handle. Remove the
tape from the plunger.
5. Slide the entire assembly back into the pump cylinder and tighten.
6. NOTE: Holding the plunger with a tool anywhere except 16 mm (5/8 ") below
the handle damages its surface in a way that quickly damages the seal.
III. MAINTENANCE - WINTER
Drain the entire installation, both to protect against frost damage and to prevent the
growth of bacteria that cause unpleasant odors.
1. Open all secondary valves.
2. Unscrew the base drain plug [9,10].
3. Disconnect the outlet flange [14] from the pump (if possible, do not remove
the hose from the outlet bend [16]).
4. Loosen the hose clamps and disconnect the hoses from both safety valves. Use
the pump handle [36] to drain the water. Make sure the tank is completely
drained.
5. NOTE: The use of antifreeze is not recommended as there is a possibility that
antifreeze will penetrate the entire toilet system. If anti-freeze is required, it
must be glycol-based.
If you plan to renovate the toilet in the spring, now is a good time to completely
dismantle it.
CAUTION! Risk of valve opening by mistake.
If the toilet is disassembled / disconnected and the valves are opened while the
unit is in the water, water will pour in and may cause sinking, which can lead to
loss of life.
It is necessary to put a warning notice on the valves and, if possible, close the valves
with a wire.
CAUTION! ATTACH WARNING NOTES!
If the toilet is not being dismantled:
•Reconnect all hose ends and secure them with hose clamps.
•Install the base drain plug securely.
•Install the valve in the outlet bend.
•Reconnect the outlet bend and hose to the cylinder with the outlet flange
while relieving the drain hose. Otherwise, the joint may not be sealed.
