Read all safety instructions. Failure to follow the safety precautions and instructions may result in electric shock, fire,
and/or serious injury. Keep all safety information and instructions in a safe place for future reference.
Resistance
To ensure a long service life, only organic toilet waste water, water and paper should be disposed of with the lifting unit.
The maximum temperature of the pumped liquid should not exceed 80
℃
during operation. No flammable, gassing,
or explosive liquids may be pumped with this pump. This pump must not be used for other liquids, in particular motor
fuels, cleaning agents and other chemical products!
Important
Toilet paper, urine and faeces are the only substances that belong in a toilet. Everything else belongs in the garbage
can! Please note that the waste water can only be pumped into the lifting unit without pressure.
Note
Some of the accessories included in the delivery are located inside the lifting unit. Please remove the accessory bag
before installation.
Installation
The lifting unit will be installed according to EN-12056–4. The lifting unit can be operated at any commercially available
toilet with a horizontal outlet. According to the EU standard, the centre of the horizontal outlet must be 18 cm above
the floor.
Important
PRESSURE-LESS: When connecting a washing machine to the lifting unit, the waste water hose must not be
connected directly to the lifting unit, but must be supplied via a vented pipe system (e.g., via a washbasin which can
be slowly introduced into the unit). In case of direct connection, the collecting tank of the lifting unit may burst, and this
is not a warranty case. We recommend that assembly and leak testing be carried out by qualified personnel. Please
observe the legal regulations!
ATTENTION
During installation, make sure that the pump is not freely suspended from the discharge line or power cable.
Operating principle
The lifting unit consists of a tank which collects the waste water and an electric pump which is automatically controlled
by a pressure switch. The pumping function is activated when the flush is activated, just like a normal toilet. The
materials to be conveyed are collected in the container. The air chamber measures the air pressure flowing through the
pipe to actuate the pressure switch. The pressure switch starts the engine that drives the turbine/shredder. The waste
water is conveyed away through the outlet. This mechanism is simple and the unit is made of high-quality materials.
The function is based on a proven concept. The lifting unit consists of a housing with a built-in pump which
automatically drains acidic, fatty, and hot water (up to 80
℃
), faeces and toilet paper via a pipe with a diameter of
28 mm, 32 mm or 44 mm to the next sewage system. They are designed to collect waste water from sanitary
installations in bathrooms (EN-12050–3, EN-12050–4) or kitchens, including washing machines, dishwashers, and all
other appliances. The non-return valve included in the packaging must be installed. The standard EN-12050–3,
EN-12050–4 stipulates that if a WC is connected, only a shower, a bidet and a washbasin can be connected, too.
The lifting unit cannot be installed on appliances such as washing machines and dishwashers if it is connected to the
toilet. If the water flow in the tank cannot be interrupted during normal operation, a device with the same capability
must be used which will automatically switch on if necessary. The installation must comply with the European standard
EN 12056–4. Fix the container with two plugs (
⌀
3.5 mm) or a similar device using the fixing holes provided. The lifting
unit can be connected to any toilet model with a wall drain according to European regulations. It is fixed by inserting the
WC drain into the rubber sleeve which comes out of the housing and screwing the supplied clamp.
The connection of the drain is on the top side of the appliance and the other consumers in the bathroom or kitchen are
the thin sides of the appliance. The connected appliances should be operated separately and not continuously
(e.g., shower). The shower and bath drains must be at least 10 cm from the floor. All connected sanitary
facilities must be able to interrupt the flow of water. If the auxiliary inputs are not used, fit the appropriate stopper.
Checking the assembly of the check valve. If the waste water is to be pumped upwards, install the check valve as
close as possible to the lifting unit. Emptying toilets and other sanitary units. Connect the drain pipes of the other
sanitary units with the rubber connectors supplied and tighten them with the clamp. For shower and bath wastewater,
ensure that the siphon slope is at least 1 % (1 cm⁄m) so that the wastewater flows to the lifting system by natural gravity.
If other sanitary units are connected along the disposal circuit near the lift, install check valves in the appropriate drain
pipes to prevent backflow. The slope of the horizontal components must be at least 1 %. For the lifting unit to switch on
when discharging waste water, the incoming waste water pipe should have a gradient of at least 2–3 % and a height
difference of at least 20 cm from the siphon to the inlet to the lifting unit. This is both necessary so that the pressure
switch in the toilet lifting unit is activated, the lifting unit is switched on and the water is pumped out. Possible errors if
this is not considered: the lifting system does not pump the water out, there is always residual water in the pipes,
there is residual water in the shower tray.
