vice. Please read the operation instructions carefully and make sure you have understood its
content.
Always use a grounded power connection with the appropriate mains voltage. You can find the corre-
sponding mainsvoltage on the type plate. If you have any doubts about the connection being grounded,
have it checked by a qualified professional. Never use a faulty electric cable.
Do not inspect the electrical part of the pressure pond filter in a wet or damp environment or when you
are wet yourself and protect it from direct sunlight. Install this device in a safe location so that nobody
can step on the cable, fall over or damage it. Disconnect the power plug before cleaning it and use only
a damp cloth for cleaning. Avoid using cleaning agents and make sure that no liquid entersthe electrical
part of the pump.
The electric part of the device contains no parts that can be inspected or serviced by the user. Leave
the maintenance, adjustment and repair to qualified technical personnel. In case of unauthorised inter-
vention the 2-year warranty is no longer valid! Keep these operation instructions safe.

Stability
To ensure the macerator’s long working life, the user should make sure that only organic toilet sewage,
water and toilet paper are removed with the toilet waste pump. The max. temperature of the pumped
fluid should not exceed +50°C in permanent operation.
This pump must not transport flammable, gas-emitting or explosive liquids. It cannot be used for other
fluids, like fuels, cleaning agents and other chemical products!
Installation
The macerator is installed according to the EN-12056-4 directive.
The unit canbeoperated on every standardtoilet with a horizontal outflow. The midpoint of the horizontal
drainagemust comply with the EU-Standard: 18cm above thefloor (Rohrbau/pipework: 18cm above the
ground according to FFB).
If a washing machine is connected to the macerator, the drainage pipe/hose must not be directly con-
nected to the macerator but it has to be led/coupled via a vented pipe system. If connected directly to
the macerator, the collecting tank may crack and this does not fall under warranty.
ATTENTION:
Pay attention when installing the unit, the pump must not be mounted freely suspended from
the pressure pipe or the power cable.

Functional principle
The macerator comprises a tank that storages the waste water and an electrical pump which is auto-
matically controlled and operated via a pressure switch.
The conveying/transporting function is activated when the flushing is operated, just like in the case of a
normal toilet.
The substances to be removed by pumping are collected in the tank (A). The air chamber (B)
measures the air pressure that flows through the pipe (C) in order to activate/operate the pressure
switch (D). The pressure switch starts the engine (E) that activates the turbine (F). The sewage is
transported and removed through the outlet (G).
This mechanism is easy and the unit is made of high quality materials. The operating principle is
based on a proven concept.

Discharging the toilets
d) Connect the horizontal departure of the toilet bowl with the rubber cuff of the pump system
and stretch the connection with the enclosed bell. Take care that you if necessary use a
lubricant, so that the rubber connection does not break.
e) Join the drain pipe with the rubber connection piece, the pipe should have a diameter of 40
or 32 mm. Seal the connection with the clamping piece.
Check the installation of the non-return valve
f) If the sewage should be transported / pumped upwards install the non-returnvalve as close
as possible to the macerator.
Discharging waste form toilet and other appliances
Connect the discharge pipes of the other appliances to the rubber connectors provided and clamp with
the pipe.
For bath or shower waste water, check that the slope from the Siphon has a gradient of at least 1 cm
per meter so that the waste flows by gravity to the Macerator. If other appliances are connected along
the discharge line near to the macerator, install check valves on their discharge pipesin order to prevent
waste return.
The slope of the horizontal parts of the discharge line must have a gradient of 1 cm per meter.
Pressure switch inspection
Plug the pressure tap chamber located in the rubber tank, press it down to create pressure and listen to
hear if there is a click indicating that the motor has switched on. If there is no click, also that the air
chamber of the pressure switch pipe nozzle does not leak.
If the appliance is switched on, themotor should start running.
Before performing this operation, check that the opening or inside of the pressure tap chamber are not
blocked.

Review the pressure switch
You trim this one to fastenings in the rubber container at, you push the excrement tank to below,
around pressure to in the inner one you produce and pay attention on this, whether you hear a click
noise. Clicking is switching the push button switch, this means that the engine would start. If you do
not hear any click noise, you make sure that the air cell of the push button switch pipe does not have
any leak or the excrement tank is leaky.
One can by also easy the push button switch puffs into the transparent tube, which leads to the push
button switch trigger, one hears, one the switch switches and the engine must call if click. No water may
be in the transparent tube and the push button switch! Otherwise push button switches dry or replace.
Cleaning the unit
The toilet pump macerator must be cleaned from the outside only with mild cleaning agents like damp
cloth and soapy water. Damage caused by inappropriate cleaning agents does not fall under warranty.

Detailed error descriptions and solutions
Residual water in the shower
Should order the lifting equipment at the discharge of waste water turns clean the feeding waste water
line have a slope of at least 2-3% and a height difference of at least 20cm from the siphon to the en-
trance of the pumping system .
This is both necessary so that the pressure switch in the toilet lift system works properly, the lifting unit
turns on and pumps out the water. Possible error if this is not taken into account is that the lifting sta-
tion does not empty the water or getting into the shower tray is too high residual in the pipes or possi-
bly back .

Loud noises , engine running or not hard at , water is not discharged
These are the symptoms of a blockage of the lifting system .
If the system is clogged with toilet paper and faeces , it is sufficient in most cases , carefully rinse the
system backwards with water. To do that, the output of the lifting station just a little water pressure, eg
so that the residues are flushed out of the pump body back to the lifting unit with a garden hose.
Please make sure that no water pressure comes on the collection of the lifting system. Otherwise, the
pressure switch of the lifting unit is damaged and the automatic on / off does not work properly any-
more .
With stronger obstructions / blockages by solid bodies that have jammed in the pump body , an open-
ing of the pump may be necessary so that the solids can be removed.
For strong shocks through the solids in the pumping system , it may even happen that the motor bear-
ings damaged. In this case, the motor of the lifting unit must be opened and the bearing be replaced.
This error is usually expressed after removing or flushing of larger solids. The lifting unit can then be
rotated by hand still free, but once you try to start the engine it blocked and only hums .
The flushing out of the lifting equipment requires no technical knowledge . Opening for cleaning should
be left to a qualified technician . In this case, you can contact us happy . We will then prompt you to
clean the lifting plant thoroughly and send it to our workshop.
Pump system does not pump out and is in the jog
This problem occurs with macerators (toilet pump systems), which were shut down (no electrical power)
but still supplied water; pressurized wastewater from a dishwasher or washing machine was supplied,
or it had more intake water than the pump could convey. As a result the pump system was "overfilled".
In this connection it can happen, that water penetrates in the pressure switch of the macerator and its
proper functioning is impaired. Then the toilet pump system either runs permanently or no longer
switches on automatically. This problem can be quickly solved and does not affect the guarantee.
You should proceed as follows
1. Disconnect the macerator from the mains voltage (pull out the plug).
2. Release the two screws (narrow sides) from the cover lid of the macerator
and remove it. (the cover)
3. Empty the small transparent hose which connects the big "tank" with the small black "control box".
Dry up the pressure switch in the small black box. (put it on the heating system or in the sun.)
4. After it had dried up, assembly the unit again in the reverse order.
5. Put the macerator into operation.
If you do not trust yourself to carry out this work, our technical service can do this for you. However I
would like to remind you that this case of malfunction does not fall under manufacturer’s warranty and
the costs for work and transportation will be borne by the customer.
