4.4 Cleaning in Case of Malfunction
The following measured variables or their change from the original values (cf. operating
certificate) are indicators for the need for cleaning or disinfecting the system.
The WTC 600 service kit (2.901.044.0) is intended for cleaning the WTC 600. Apart from the
cleaning chemicals and a wet-dry vacuum, it contains all the equipment needed for cleaning and
conserving the WTC 600 LP and MP.
The cleaning chemicals must be ordered separately.
The system should be cleaned if the following differences occur compared to the initial startup
- The drinking water flow drops by 200l/h at the same pressure
- The conductivity doubles at the same pressure and temperature
- The differential pressure between the pump pressure and concentrate pressure increases
by more than 2 bar.
Alkali cleaning with RM MCT 511 first, then acid cleaning with RM MCT 103.
Only disinfect if cleaning is unsuccessful.
