5 Technical description
5.1 Use according to the regulations
By asbestos sanitation works within closed rooms, you have to exclude that the asbestos
fibres leave the area of operation uncontrolled and endanger the human health and the
environment. For this reason, persons must leave the area of operation through a lock
system and take a shower before they exit.
The deconta water treatment assumes the heating of the shower water and takes over
the filtering of the contaminated sewage water
5.2 Device description water treatment
The built-in geyser in the water treatment provides the heating of shower water. The
sewage pump will automatically start along with the shower process. This sucks out the
waste water from the shower. Through a pre-filter and two fine filters, the wastewater is
cleaned so far that it can be fed to a sewer.

5.3 Waste water pump
The self-priming sewage pump is installed, ready for operation, in the water treatment.
She sucks the contaminated shower water through the pre-filter and then pumps it
through the two fine filters. The built-in pressure switch protects the filter plant from
excessive overpressure. While showering one automatic ensures that the pump is
started and runs during the entire process. A manual starting is possible with the key
"sewage pump start"
5.3.1 Model with 2 waste water pumps
Optionally, the WM 400 V can be equipped with a second sewage pump. This sucks in
parallel with the first sewage pump the contaminated shower water through a separate
filter and pumps it then subsequently through the two common fine filters. Typical use
case is a 5-chamber lock with two shower chambers

5.4 Waste water filtration plant
The waste water filter system is used for filtration of contaminated shower water.
In the three-stage filtration system consisting of a pre-filter (220), a pressure gauge for
filter monitoring and two fine filters (50, 1), the water is filtered and discharged through
the drain line.To achieve a constant flow pump, the fine filters have to be changed at a
too strong fouling.
We recommend a filter change of the two fine filter at about 3.0 bar
The pre-filter is to clean up pollution
Filter change:
Unscrew the cap nut
Remove and dispose of the filter
Insert the new filter cartridges
Tighten the cap nut
Damaged filter cartridges can not be reused
All the filters mentioned must be disposed of in accordance with statutory regulations.

5.5 Instantaneous water heater
The instantaneous water heater is completely electronically controlled and heats the
water as it flows. The electronic regulation and control unit detect the water flow, the inlet
temperature and the temperature selector at the specified outlet temperature. The
microprocessor calculates the required value and turns on the appropriate heat output.
When closing the hot water valve, the heater is turned off independently and the
electronic all poles system disconnected from the mains. The device consists essentially
of the heating block, the power module with triacs, the electronic module, a safety
temperature and pressure limiter and the pressure differential switch.
Heating coils are used as a radiator, which are surrounded by flowing water directly. By
this heating mode and with 0.5 litres of very low water content, a high efficiency is
ensured. The amount of water is limited by a built-in flow control by fully open hot water
valve to max.10l / min flow rate so that a suitable outlet temperature for the shower
(about 40º C) remains.
Thanks to the built-in temperature and pressure safety limiter, a double safety shut-off is
reached by over pressure and over temperature. The pressure limiter triggers by a rise in
pressure to about 22 bars, the temperature limiter triggers at about 55º C in the intake
and at about 70º C in hot-water outflow. In response of the pressure or temperature
limiter the device is disconnected at once from the mains.
Prior to press again the pushbutton on the safety temperature and pressure limiter, the
cause of the disorder is to be determined and resolved by a qualified person

7 Initial operation
7.1 Connection assignment to the personal lock system Quick-Dush
Establish the current supply of the water management (400V, 32A 3+N+PE)
Establish the fresh water supply of the water management to the connection “fresh
water filling”.
Establish connection “warm water exit” with the shower roof element
Establish connection “sewage water suction” with the shower floor element
Connect the drain hose connection with "waste water” and sewer
7.2 Preparing for operation
Open fresh water intake
Fill the sewage pump (see chapter 8.2 )
Set the temperature of shower water at the thermostat
Set the main switch to „ON“
The system is now operational
Note:
Before the start up of the sewage pump, it is to verify whether the shaft can be turned by
hand. On this purpose a screwdriver has to be put in the notch on the shaft extension of
the fan side and move the shaft. With new pumps, the strong initial rotational resistance
of the wheel will come loose after running.

8 Maintenance and care
The suction hoses, pumps, filter housings and filter are contaminated after the
first use. Repairs and maintenance have to be executed only under the observance
of all relevant safety measures.
8.1 Daily maintenance
- Control if the hoses have a continuous flow
- Control of the sewage water filter pressure gauge
- Visual inspection of the pre-filter for contamination
8.2 Sewage water pump
In case of frost danger, the stopped pump has to be emptied through the drain plug.
After a long standstill this is to check, before restarting, if the wheel has been blocked by
deposits caused by impurities, sediment and other causes. You may clean with
appropriate measures.
Caution! All works on the unit are to be performed only if the electrical power has been
turned off.
Before commissioning, the pump must with the fluid through the vent port to be fully
populated
Note: The pump must not be operated without liquid filling. Before operating, the pump
must be filled completely with the fluid through the vent port

The safety limiter
Changes in the safety temperature and pressure limiters are not
allowed! In all the disorders, we recommend to consult the service.
For the activation of the safety limiter, after the remedy of a previous
disorder, a screwdriver or similar should be introduced through the
opening of the cap and carefully pressed until the limiter clicks.
Information: Upon request, deconta concludes a service contract with you.
