3.2.4d.ORP Calibration
Due to the characteristic structure of ORP (RX) sensors, the
measurement values change over time. The change in the sensor
measurement value affects the value displayed by the device. For
this reason, sensors must be calibrated periodically with fluids with
an ORP (RX) value known (475mV). ORP Calibration parameter is
used to perform this operation.
The OK button is pressed once and the parameter is entered,
to exit the parameter, the MENU button must be pressed once.
After entering the parameter, a screen like the one shown is
displayed. The ORP (RX) sensor is immersed in 475mV liquid and
the sensor is left in the liquid until the timer on the screen is reset.
When the timer is reset, the ORP (RX) sensor is calibrated.
3.2.4e.ORP Read
Read ORP parameter; It is the parameter that shows the
instantaneous value that the ORP sensor reads. The OK button is
pressed once and the parameter is entered, to exit the parameter,
the MENU button must be pressed once. After entering the
parameter, a screen like the one shown is displayed. No action is
taken, only the reading the sensor displays instantly.
3.2.5.PROGRAM MENU
It is the setting page where GEMAŞ technical personnel can intervene. Modifying this page may damage
the overall operation of the device.

CLEANING - MAINTENANCE INSTRUCTIONS
4.1.
Electrode Cleaning
Although the physical properties of the water used vary depending on geographical regions, it inevitably
contains certain amounts of calcium, magnesium, iron, and other minerals. While the water is cold, these
suspended minerals decompose from water during electrolysis, some of them stick to the electrodes in the
chamber. After a certain period, the electrodes are completely covered with the substance called lime. Since the
lime layer is insulating, they complicate the flow of electricity between the electrodes. As a result, chlorine
production efficiency decreases. This lime formed in the electrodes must be cleaned periodically.
This cleaning process; It has the feature to do it automatically by changing the polarization. However, in
cases where the calcium concentration is too high, this feature may not completely remove the limescale.
Regularly check the lime sediment in the cell and, if necessary, clean the cell manually.
1-
Turn off the pump and salt chlorine generator.
2-
Close the water inlet and water outlet valves of the electrode cell.
3-
Open the threaded electrode head, properly disconnect the electrode cable from the terminal and
remove the electrode from the chamber.
4-
Ideally, if the electrode is expected to dry for a day, the lime residue releases itself. During the
process, be careful not to damage the sensitive cover of the electrode and take care. During this
process, never hit with metal material that can scratch the electrode. Pressurized water can be used to
dissolve limescale.
5-
If the pressurized water could not remove the limescale, you can immerse the electrode in a 20%
hydrochloric acid solution. The terminals at the top of the electrode must not touch the solution.
6-
Immediately after cleaning, the electrode must be rinsed with clean water, the place of the terminals
must be carefully dried and reassembled.
Never leave the electrode in acid for more than 5 minutes! Do not scratch the electrode with metal
objects! For safety reasons, keep the acid in water! Never leave the electrode in acid for more than
5 minutes! Do not scratch the electrode with metal objects! Soak the acid in water for safety
reasons!
