Installation
5.1
Select installation location
A freely accessible installation location should be selected to facilitate operation and subsequent maintenance tasks. The
installation location must be protected from frost and the device may not be exposed to direct sunlight.
5.2
Mounting the device on the wall
Select the installation height so that the device is located at eye level. Measure the four drill holes on the mounting plate and mark
their location on the wall. Use the included four black plastic spacers to ensure the required distance from the wall.
5.3
Voltage supply
The devices must be supplied with continuous voltage. I.e., the voltage supply must not be locked with the filter system. For
locking with the filter system, please use the external off input.
The permanent voltage supply is required for the proper execution of the disinfection dosing by means of active oxygen. This also
prevents condensation corrosion.
5.4
Assembly notices
Only "good" basin hydraulics can achieve a satisfactory control of the two auxiliary hygiene parameters, pH value and redox
voltage. The dosed chemicals must reach all areas of the basin within a short time. Even under stress, the concentrations
measured in different areas must be approximately the same. The measuring water should be as close to identical to the basin
water as possible and must reach the measuring cell as quickly as possible. This is the only way to quickly detect and rebalance
changes in the water quality.
If the basin water is conducted through an overflow gutter and a compensation basin (splash water), which is potentially also used
for the freshwater feed-in, only the sampling of the measuring water directly from the basin will lead to satisfactory measuring and
control results.
At very low temperatures <5°C, the touch screen may become impaired due to the stiffness of the frontal film!
5.5
Provide external pre-filter
It is not possible for the pool operator to detect a contaminated pre-filter below the new design cover. For this reason, an external
pre-filter must be integrated in the measuring water inlet. Depending on the local conditions, the pre-filter can be installed directly
at the device or at any other installation site along the measuring water inlet. This has the advantage of making it possible to select
a more convenient access point for the pool operator.
