WDT POOLKLAR Touch XL
Original Bedienungsanleitung in deutsch - Version (V1.1 –2012_01_09) 6/24
4 Installation
4.1 Place of installation
For ease operation and maintenance please look for a good accessible mounting place, not at risk of
frost or direct sun shine.
4.2 Tapping points for measuring water
Only with good hydraulics a reasonable effect of the auto-control of the pH and the redox can be
achieved. The dosed chemicals should reach all places in the pools within a short time (< 5 minutes).
Also with bathers load the chlorine concentrations should be similar at different places of the pool. The
measuring water in the cell should be identical to that in the pool. So it should be conveyed as fast as
possible to the cell.
If you have an overflow system with balance tank and fresh water supply herein, this must be
considered. If highest quality is required, a extra pump for the measuring water is to be mounted.
It is recommended to link the power supply of the POOLKLAR to the power supply of the filter pump.
4.3 Installation proposal
Normally the water take off is between pump and filter, the injection behind the heat exchanger. For
the connection to the piping please use the by-packed valves with emerging tubes, that are to be
shortened so that their end is reaching to the middle of the pipe.
ACHTUNG!
As the water behind the POOLKLAR is very corrosive, the injection point should be behind
the heat exchanger.
At an overflow system it is recommended to install an extra measuring water pump

Original Bedienungsanleitung in deutsch - Version (V1.1 –2012_01_09) 7/24
5 Commissioning
Before taking into service the following points have to be worked through. Please see for this too
point 3.4 page 5.
5.1 Setting of the Control parameters –see for this page 22 “Commissioning form”
The POOLKLAR is at works set with certain parameters that are to be adjusted to the needs of your
pool. Normally you can use these parameters for start and change them after some days when you see
the reaction on your pool water quality. The most important will be the look on your values for free
chlorine.
5.2 pH-Electrode
Take the pH-Electrode from the packing and pull off the protection cap. Screw off the connector head
and screw the electrode into the cell. Now screw on the connector head again on the electrode.
After an hour time it is to check whether a calibration is needed. For this take out the
electrode again from the cell and place it in the buffer solution pH 7,0. A calibration is
needed if the indicated value has a difference to 7,0 more than 0,1.
5.3 Cleaning glass beads
The blue glass beads are to clean the surface of the platinum electrode to get stable values for the
redox tension. Pull off the cable from the redox electrode (10) and screw out the PVC electrode holder
from the cell. Now put the glass beads onto the platinum surface to cover the surface. Screw in again
the electrode into the cell and push in the cable to the electrode.
At screwing in the Redox-Electrode pay attention that no glass beads are in the thread.
ATTENTION!
Check all tube connections to be dense. Plastic connection are only fastened by hand!
5.4 Measuring water flow
At the flow control valve (9) the water flow is to be adjusted. The switch bobbin must be pushed to
top. Only in this position dosing is possible. The glass beads must rotate on the electrode surface; they
should not be lifted by too high flow of the water.
5.5 Dosing pump heads
Push the dosing heads on the motor shaft till the lockers do „klick“.
5.6 Chemicals
Place the two chemical containers under the POOLKLAR. It is strongly recommended to place them into
safety tubes to prevent leakage on the floor: Left, acid –right chlorine.
Place the suction lances into the containers.
red = acid - yellow = chlorine
For the right function of the POOLKLAR it is important to know what disinfection chemical
was used before. If it was other chlorine or non chlorine type there are reactions in the
water that may affect the disinfection capacity of the chlorine now in use.
Chlorine compounds on organic basis (Dichlor, Quickchlor and others) do reduce the redox tension at
same measured chlorine levels at use for longer time; the disinfection power of the chlorine is reduced.

WDT POOLKLAR Touch XL
Original Bedienungsanleitung in deutsch - Version (V1.1 –2012_01_09) 8/24
That means that at a certain level of the redox tension you get higher chlorine concentration. If you
don’t want the higher chlorine level, you have to select a lower set value for the redox tension, but
that means lower disinfection power. Best would be in this case to empty your pool and to fill fresh
water.
5.7 Switch off at backwash and vacuuming
During backwash the circulation back to the pool is interrupted but the water supply to the
POOLKLAR is not. Dosing could run on to the standing water in the return pipe. It would be
possible that after finishing the backwash high concentration of chlorine could be flushed to
the pool. To avoid this it is recommended to switch off the POOLKLAR during backwash.
If the vacuuming of the pool floor is executed through the filter we get high pollution rates to
the POOLKLAR that will block the filter on the system. So we recommend switching off of the
POOLKLAR in this time too.
6 Electrical connections
6.1 To open and close the housing
No tools are needed.
To open the housing cover you lift a little the lower and upper sideward
clips and you can then lift the cover forward, the upper cover clips are
running in their grooves to their front stop.
Now the cover can be flipped up and supported by means of the strap.
Press
Klick
To close the housing the strap must be loosened to backside and the
cover is then to be closed downwards. Now loose the upper sideward
clips and push the cover backwards. To seal the cover push at all 4
edges with slight. The cover closes with a slight “klick”.
To connect additional cables to the controller at the bottom of the housing you find some „push out“ for
cable connectors.

7.1 Operation Indication and Programmes
7.1.1 Normal operation
The values are indicated and controlled
No irritation
7.1.2 QuickInfo
With the function QuickInfo, the control parameter for pH-value,
redox-tension und temperature can be seen directly.
For this touch the wanted field
No change of the parameters is possible
7.1.3 Dosing delay
At any switch on of the POOLKLAR dosing is suppressed for the
set delay. This time has to be chosen so long that it is sure that
actual pool water flows through the measuring cell.
Software alarms are suppressed in this time
With touching this time can be interrupted (e.g. at a
maintenance job) and the POOLKLAR is running as set.
7.1.4 Start routine
If one of the values is outside the control range (p-range) a
dynamic dosing time monitoring is active: if a measure value does
not reach the control range with a certain time dosing is stopped
and alarm is given.
This irritation is indicated by the symbol and can only be reset
by a new start or a manual reset.
Dieses Zeichen fehlt hier! ?
7.1.5 Alarm
The symbol in the “out”-line indicated 1 or more alarms. The
alarm relay is activated.
We distinguish between alarms (software-alarm e.g. alarm high,
alarm low) and irritations (switch inputs).
At alarms the value is red colored. At irritations the according
symbol is shown in the “In”-line.
Alarms resp. irritations must be active at least for 5 seconds to be
indicated.

Identical to the Settings for pH. If you measure too high values for
free chlorine: set lower values for redox or contrary
7.2.1.3 Main menuSettings dosing capacity
This is to adjust the dosing capacity to the chemical consumption
needs of the pool.
Especially for small pools this is important to avoid overdosing.
If the values change up and down: lower the dosing capacity
and/or increase the proportional range
If you get the alarm indicating that the set value cannot be
reached: increase the dosing capacity or lower the control range.
Cycle time
Dosing is organized in cycles to avoid coming together of the two chemicals whereby for both chemicals
dosing times and pause times are defined. The shortest dosing cycle is 120 seconds, maximum dosing
time is each 50 seconds with each10 seconds pause in between. That means that all 2 minutes dosing is
activated in relation to the distance to the set point.
An extension of the cycle time does extend the second pause time and so the dosing capacity is reduced.

The calibration mode is conducted by real texts. By touching the AOKA the done steps are quit.
Calibration values are taken if the value is stable for 15 seconds. At the end the reached electrode values
are indicated and an evaluation of the electrode quality is done. At small deviations the calibration is
taken over; at greater deviations a information „cleaning” or “exchange” is given.
7.2.2.1 Main menu calibration pH- electrode
The ph-electrode gives as measuring signal a tension that is
converted to pH indication.
pH7 = zero point tension
the zero point tension should be 0mV +/-30mV.
pH4 = second check point to define the performance of the
electrode.
mV/pH = slope
the slope at 25°C should be 59 mV/pH
example: (mV at pH7 –mV at pH4 = 3pH x 59mV = 177mV)
Evaluation of the pH-electrode:
Indication „cleaning“
At a zero point tension > +/-41mV the indicated value is colored yellow and the mark for
“cleaning” is indicated. Same indication at a slope < 52mV or > 63mV/pH.
Indication „irritation“
At a zero point tension > +/-61mV the indicated value is colored red and the calibration is not
executed. Same with slope < 50mV or > 65mV/pH. The electrode is faulty and must be
changed.
If the calibration is not executed cause of faulty electrode, the control runs on with last
values.

7.2.2.2 Main menu calibration  redox- electrode
With the menu calibration  redox- electrode the redox-
electrode is to be calibrated. The redox buffer solution of WDT
brings a tension of 468mV at 25°C, see label.
As the check tension is free to choose this calibration can be done

7.2.3.1 Main menu Service output test
The output test is to check the function of the connected pumps and relay. The selected output is active
for 100 seconds. Touching AEsc. the test function can be interrupted any time.
Cause of safety reasons the dosing tests function only when the measuring water flows well, no
interruption is indicated.
7.2.3.2 Main menu Service input test
The input test is to check the function of the connected monitoring switches. The status of the switch is
indicated by a „0“(open) or “1”(closed).
All the switches (level and measuring water flow) are open in normal operation and closed to indicate
irritation: container empty, low measuring water flow.

8 Maintenance
All maintenance job shall be done by qualified personal. Need spare parts are to be supplied by
the dealer. Please pay attention to the safety indications at the chemical containers and wear
adequate protective clothes.
Maintenance jobs to do:
-clean filter if scaled
-calibrate the pH- electrode at a difference >0,2pH against the measuring with Phenol-red
-clean the inserts of the dosing valves –especially the chlorine one –every season or change if
worn
-change the dosing pump heads every season
-change the seals of the redox-electrode every season
8.1 Filter
The filter is to be cleaned if visually scaled. Especially in spring or autumn time it can be necessary more
often.
Advice!
A scaled filter leads to a higher consumption of chlorine; the chlorine reacts with the organic
material depressing the redox tension of the measuring water. Subsequently the chlorine
concentration in the pool water will rise.
8.2 pH-electrode
Attention!
At doing any job with a pH-electrode pay attention that no humidity comes into contact with
the connectors! Even smallest humidity will lead to a faulty electrode. The contacts must shine
golden and may not look corroded.
All sensors suffer under wear. The live time in swimming pool water should be at least one season, could
be 2 years. With the time the performance of the electrode will change cause of scaling of the diaphragm
and ageing of the sensor glass. This leads to deviations in the measuring value and a cleaning and
calibration in needed.
For cleaning the electrode only dunk it into the cleaning agent. Never use tiles or paper to clean the
sensor glass and diaphragm.
Advice!
After each cleaning or change of the electrode you must calibrate it again.
8.3 Injection valves
The yellow injection valve for chlorine solution tends to be blocked by calcium incrustations. Depending
on the water factors temperature and calcium hardness a cleaning can be necessary within weeks or
months. The sign for the need of cleaning is the blockage of the chlorine dosing and subsequently
indication of chlorine low alarm. It is recommended to clean the injection valve frequently to avoid
blockage of the dosing and stress/shorter life time of the pump.
The calcium incrustation can be easily dissolved by hydrochloric or acetic acid.
The parts 1, 3, 4, 5 und 6 are assembled ina
maintenance kit.
Advice
Please pay attention to the right assembly of the parts. Otherwise you will have irritations in
the function.
