VIII - SERVICING AND MAINTENANCE
Servicing
Checking the mechanism
If the flow rate drops or the temperature becomes unstable, check the condition of the
mechanism. If necessary, clean and descale the mechanism using a weak acid solution
(vinegar, etc.) and brush the filters. If the problem persists, replace the e-Cartridge.
Checking the temperature
Regularly check that the mixed water temperature matches what is shown on the control
unit screen.
Draining down in freezing temperatures
If the device is to be exposed to freezing temperatures, draining down is essential:
- by opening the low-point drain valve; or
- by opening the device.
Updating the built-in software (via the microSD card)
Updates are performed via the microSD card, and newer software versions are made
available on our website.
Update files must not be renamed and must retain the .hex extension.
Updating is only possible if the new version has a number > the installed version.
The product contains 2 software versions:
- The factory version
- The operational version the control unit runs on.
The “factory” version is a stable fail-over version to be used in the event of a problem
during an update.
The factory version is saved when the system is first powered on PROVIDED the
microSD card is present in its slot.
While saving the factory version, the screen below is displayed:
