Operation manual SOLDOS - SL
Dosing station for the fine nebulisation of brine solution
for dry rooms, e.g. Tepidariums to create a salty sea
climate in the atmosphere of the room.
Safety instructions
1. Before the installation of a SOLDOS all materials in the
room have to be checked on their corrosion resistance
against the saline mixture of water and air both in the
adequate steam cabinet and additional and discharged
air shafts.
2. Use only pure, disinfected WDT brine solution with a salt
concentration of app. 5%. WDT brine solution is
delivered in a sterile condition in a closed container.
Outstanding brine solution is affected by bacterial
impact and so should not be used.
3. Consider disinfection instructions and durability of the
brine solution! (see point 4.3)

1. Application
The Soldos-SL nebulises brine solution for dry rooms by the use of a two-
component jet nozzle (compressed air and brine solution). After a short
time a salty sea climate is created in the room.
Due to the variety of setting parameters it is easy to adopt the SOLDOS-
SL to the site of operation. The dosing capacity depends also on the room
climate (humidity, temperature) and the air circulation rate. In general
useable for rooms with a floor space of app. 35m².
1.1 Function
The brine solution is primed out of an air sealed bag (Politainer) by a
peristaltic pump. This bag interfolds itself when the liquid brine solution is
taken out. This procedure prevents the contamination of brine solution
with germs of the ambient air. The peristaltic pump conveys the brine
solution to the two-component jet nozzle where it is nebulised and blown
into the room by the addition of compressed air.
The compressed air for the nebulisation has a follow-up time of 10 seconds
to prevent encrustation at the nozzle and follow-up dripping at the nozzle.
If the brine bag gets empty the nebulisation stops and the green-LED
blinks. An electrical output for a malfunction message can be connected.
The empty report is realized by an empty switch.
1.2 Option: additional functions
The controller of the SOLDOS-SL gives also the possibility to equip the unit
with additional attractions such as light and sound effects (MP3 sound
module). These attractions can be switched-on in parallel to the
nebulisation of the brine solution. This offers the possibility to create
ambience together with the salt infusion.

3. Installation
Before the installation of a SOLDOS all materials in the room have
to be checked on their corrosion resistance to brine solution!!!
If the SOLDOS is used in wodden cabinets the resistance of the
wood has to be checked. Additionally the wood has to be cleaned
regulary.
For the use in Saunas the Sauna Heater has to be resistant against
corrosion (stainless steel housing).
Attention!!! –please use only pure, disinfected WDT brine with a
salt concentration of app. 5%.
The SOLDOS has to be installed on a capable place next to the accordant
cabinet, but not directly on the back board of the wall as a disturbing noise
due to vibration might come up. Electrical supply by power socket
230V/AC.
We recommend to install the hose pipe for the brine solution and for the
the compressed air in a standard empty conduit d20.
Minimum installation radius of the empty conduits should be 20cm.

4. Assembly of the nozzle
For the installation of the nozzle and the covering screen, a borehole (100
mm) has to be done through the wall of the room (see picture). The
grommet/ mounting sleeve has to be glued-in diffusion resistant, in order
that the cover screen of the nozzle rests on the cabin surface with the
sealing. For the final assembly, the hose lines are directed from the
dosing unit through the mounting sleeve and connected on the hose
connections of the two-component jet nozzle. Now the cover screen is put
onto the mounting sleeve and fixed with the incl. screws.
When connecting the hose connections, please consider that the
compressed air piping and the brine dosing tube are not interchanged.
The difference between both hoses helps you here. For the compressed
air piping, a PE hose is used –with inside diameter of 6 mm and wall
thickness of 1 mm. The saline dosing connection consists of PTFE material
–with inside diameter of 4 mm and wall thickness of 1 mm. Therefore,
the dosing unit as well as the nozzle is provided by the fitting hose
connectors.
We recommend you to pass the dosing pipes by protective
material (insulation). Please consider that the lines are flexible
(backwards), for a possible dismounting of the nozzle.

6. Taking the unit into operation
6.1 Attaching the brine reservoir to the unit
Before taking the unit into operation the brine solution reservoir has to be
attached to the unit. At the programme switch the dosing performance is
adjusted by the pause- and spraying time. The programme switch is to
set up the type of operation, the test programmes and the cycle time for
the push-button operation.
When you take the unit into operation we recommend to set the pause-
and spraying time on a middle position (pause time 4 minutes/ spraying
time 25 seconds). Starting from this values the times have to be adapted
according to the basic conditions at the point of use (measures of the
room, steam quantity). The unit has to be switched-on with the main
switch on the right sight of the controller before it can be taken into
operation.
Attaching the brine reservoir:
1. Screw-off the original lid of
the brine reservoir.
2. Pull out the special lid from
the nipple of the suction tube
of the SOLDOS.
3. Screw the special lid onto the
brine reservoir.
4. Push the suction tube with
nipple into the special lid.
5. Pull the connected reservoir
into the console. Pay
attention that the flange ring
sits correctly in the guiding.

6.2 Operation modes
The programme switch is to set the demanded programme. There are 2
general operation modes:
6.2.1 Interval operation - „continuous dosing“
At the continuous dosing the programme starts after the unit has been
switched-on. The spraying time is adjustable by a rotary knob on 5-10-
15-20-25-30-35 or 40 seconds. The pause time between the single
sprays is adjustable on 1-2-3-4-6-8-10 or 12 minutes. This cycle is
repeated until the unit is switched-off.
Put the programme switch on „continuous dosing“. The LED „continuous
dosing“ shines. Adjust now the spraying- and the pause time.
Example: pause time 4 minutes, spraying time 20 seconds
The unit sprays brine solution every 4 minutes for 20 seconds.
6.2.2 Push-button operation
The push-button has to be connected according to the wiring diagram.
The demanded cycle time is adjusted at the programme switch. The LED
“push-button operation” shines.
After pressing the connected push-button the same procedure as described
above (“continuous dosing”) starts. After the lapse of the adjusted cycle
time on 5 –10 –15 –20 or 25 minutes the dosing stopps and the
SOLDOS is ready for a restart.

Operation manual Soldos - SL (04-09) page 11 of 18
When the unit is taken into operation we recommend to set the spraying-
and pause time on a medium setting (Pause time 4 minutes, Spraying
time 25 seconds, Dosing time peristaltic pump app. 1,6l with hose 3,2).
On the basis of these values the settings have to be adapted to the
situation on site and the demanded salt intensity by trial.
For taking the unit into operation the unit has to be switched on with the
main-switch in the right side of the control housing.
6.3 Settings
The single operation parameters can be adjusted at the front plate of the
SOLDOS-SL.
Dosing performance in l/h during continous operation:
This stepless Poti is to set the dosing performance of the peristaltic brine
pump in l/h. Due to tolerances of some components of the rpm-control and
the dosing hose the effective dosing performance can vary +/- 15% of the
adjusted dosing performance.
Pause time in minutes:
Pause time in between the nebulisation intervals.
Spraying time in seconds:
This rotary knob is to set how long the spraying shall last. During this time
the peristaltic pump and the compressor works.
Attention: After the spraying time the follow-up time of 10 seconds of the
compressor is activated (see page 4).

Operation manual Soldos - SL (04-09) page 12 of 18
Test switch:
To test all functions/ components of the SOLDOS-SL.
Cycle in minutes for push-button operation –programme switch:
This switch has several functions:
1) Choice of the operation mode (see page 10 –point 6.2).
2) Activation of the disinfection resp. flushing (see page 13 –point 7).

Operation manual Soldos - SL (04-09) page 13 of 18
7. Disinfection instruction
The disinfection has to be done at every exchange of the brine bag,
at least monthly (Before the initial operation, the disinfection has
to be done as well)
The disinfection has to be done preferably before or after the
operation when no bathers are in the room!
A disinfection tablette is always included in delivery!
Disinfection:
Step 1:
Wash out the empty politainer by drinking water, fill up the
measuring bottle (200 ml) by cleaned water und add one tablet.
Lock up the measuring bottle and shake it until the tablet is
solubilized.
Step 2:
Fill in the brine solution into the empty, cleaned politainer and draw up the
politainer again.
Step 3:
Draw up the nozzle adaptor on the nozzle in the room (PVC
compact with PE downpipe hose) in order to receive the
disinfection and brine solution. By using the downpipe hose,
pipe the solution directly into the gully if possible.
This is to avoid that the solutions are atomized within the
room.
Step 3.1
Before starting the disinfection, the dosing performance of
the hose pump has to be upgraded to the highest
performance in order to assure a complete fllling of
the hose pipe.
Step 4:
Switch on the programme „disinfection“. The pump is
dosing the solution for 4 minutes now. Within this time,
all parts are filled with disinfection solution. Afterwards,
the Soldos is disabled for 11 minutes, in order to provide
the disinfection solution enough residence time.
Meanwhile, the LED for both disinfection and flushing is
lighting.

Operation manual Soldos - SL (04-09) page 14 of 18
This procedure complies with the Ö-Norm 6222 part 1.
The Soldos is securely disinfected.
Flushing:
Step 5:
Remove the canister (with disinfection solution) and draw
the new brine canister with germfree brine solution. Turn
the programme switch to “flushing”. Now, the brine
solution is dosing for 4 minutes in order to completely
flush out the disinfection concentration.
Step 5.1
After the rinsing process, the dosing performance of the hose
pump has to be reseted to the performance before the
disinfection process.
Step 6:
Remove the PVC compact (with the PE downpipe hose) from the nozzle.
The Soldos is ready for operation again, when the programme switch is turned
back to the initial position.
Step 7:
Every disinfection has to be written down in the following protocol.
Durability
On every canister, the expiration date is stated. Furthermore, every canister
should be consumed within 4 weeks after opening.

Operation manual Soldos - SL (04-09) page 15 of 18
8. Peristaltic pump
8.1 Function principle
This type of peristaltic pump will reliably meter a
chemical solution to the injection point particularly when
low dosing rates are required with products which ‘gas
off’ (i.e. self priming). The advancing roller occludes the
tube which, as it recovers, draws in fluid that then
becomes trapped by the next roller and later expelled
from the pump. The technique offers the following
advantages:
No contamination of the fluid or the pump as the fluid
is contained in the tube
Gentle pumping action with accurate flow rates
The pump is self priming and can run dry
The pump is quiet running and very simple to handle
8.2 Changing the dosing hose
For transport and storage, the peristaltic hose kit is not fitted into the pump to
prevent deformation of the hose. For fitting push in the hose holder into the
slides at bottom of the pump housing, turn the roller so that the hose comes to
the flat part, push the hose into the housing by turning through the roller. After
some turns the hose is in the right working position. Than fit the safety disc onto
the shaft and the protection cover onto the housing

9. Maintenance
Please consider:
- Change the dosing hose of the peristaltic pump yearly.
- Check the pump head with the roller always when you exchange the
brine bag. Check if there´s corrosion or other signs of wear. The rollers
have to be even and must not show grooving.
- Check the hose connections if they are seal.
- Check and clean the air filter of the compressor monthly.
When the unit is taken out of operation we recommend a flushing of the
whole system with distilled water, to prevent incrustations. Afterward take
out the roller of the pump head to discharge the dosing hose.
When the unit is taken into operation again we recommend to do a
disinfection.
Tap water contents calcium that would block the very fine boring
of the nozzle
Maintenance of the rooms
The interior of the room has to be cleaned out with a wet towel at the end
of a day, so no deposits or incrustations will come up.
