3.2.1 Device overview
The control unit CPR-Touch XL is delivered as a ready-assembled unit. All parts are
mounted on a plastic plate or on the respective dosing device. This ensures that the device
is safely installed. Potential execution errors by the assembling personnel are thereby
avoided, as far as possible.
For transportation purposes, both electrodes along with the glass shaft have been removed
from the measuring cell and delivered in a packaging box. The roller carriers for the
peristaltic pumps have been removed from the motor shaft in order to avoid deformation
of the dosing hoses when they are stored for extended periods of time.

5Commissioning
5.1 Commissioning, - comments
The work described here may only be carried out by trained specialist personnel from a
specialist company. Prior to commissioning, the installed devices must be checked for
proper installation and leaks.
The device is delivered with defined factory settings. You can find the setting values in the
operation data sheet in Chapter 9.4.
NOTICE!
Please ensure that all hose screw connections of the measuring
water pipes are firmly tightened. Check all pipe unions at the device
and at the two measuring water ball valves ½” – 6 x 1. Plastic pipe
unions may only be fastened hand-tight!
5.2 Commissioning works
Carry out the commissioning works in the sequence indicated.
5.2.1 Insert the cleaning beads
The included blue glass beads are used for cleaning the two metal electrodes screwed in
from below (pos. 10 and 11). This concerns the chlorine and redox electrodes. Fill the
measuring cell from above with a sufficient number of glass beads to ensure that at least
the metal surface is covered, approx. 20 to 30 beads.
NOTICE!
In special cases, a sieve is installed in the infeed opening. In this case,
the electrodes must be removed and the cleaning beads filled in
from below. Subsequently reinstall the electrodes.

5.2.2 Insert pH and combination electrodes with glass shafts
Remove the two electrodes with glass shafts from the packing box and pull off the
protective cap. The union nut of the electrode cables can be removed from the electrodes
by twisting to the left. The electrodes are screwed into the measuring cell from above at
position 4 (blue) and position 5 (black). Subsequently, the electrode plug must be placed
back onto the respective electrode and the union nut must be tightened.
5.2.3 Set the measuring cell flow rate
Once all electrodes have been screwed hand-tight into the measuring cell and the
measuring water lines have been connected, the measuring water intake can be opened.
The flow volume can be adjusted at the flow control valve (pos. 6). The flow meter float
(pos. 2) must be pushed toward the top in order to release the dosing. The cleaning beads
must rotate extensively on the metal surfaces. If the cleaning beads become suspended,
the flow is too high and the cleaning effect is not guaranteed.
5.2.4 The control parameters
The device is loaded with factory-defined control parameters. Please adjust the control
parameters for your pool according to the required dosing performance and the desired
setpoints.
The mechanical commissioning is now completed. Continue with Chapter 6, Operation and
service of the device in order to adjust the control parameters to your swimming pool and
to optimise them.
NOTICE!
Following a temperature adjustment and inflow time of approx. one
hour, the electrodes must be calibrated.
