Operating Instructions
Your AXOR Citterio M Thermostatic Rough-in Valve provides precise control over water temperature and flow to two separate outlets.
Temperature Control:
- The lower handle controls the water temperature.
- Rotate the handle to adjust the temperature. Turning towards the left typically increases hot water, and turning towards the right increases cold water.
- A safety stop is set at 38°C (100.4°F) to prevent accidental scalding. To exceed this temperature, you must consciously override the safety stop by pressing a button or moving the handle past a resistance point (refer to specific handle design).
Shut-Off/Changeover Valve (Flow Control):
- The upper handle typically controls the water flow and selects between the two connected outlets (e.g., shower head and hand shower).
- Rotate the handle to turn the water on/off and to switch between the two consumers.
- The valve allows for a maximum flow rate of 26 liters per minute.
Maintenance
Regular cleaning and proper care will ensure the longevity and optimal performance of your AXOR Citterio M Thermostatic Valve.
Cleaning the Chrome Finish:
- Use only mild soap and water or a cleaner specifically designed for chrome finishes.
- Apply the cleaner to a soft cloth, then wipe the surface.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Do not use: Abrasive cleaners, scouring pads, ammonia-based cleaners, or cleaners containing bleach, acids, or solvents, as these can damage the chrome finish.
Thermostatic Cartridge Maintenance:
- In areas with hard water, mineral deposits can affect the performance of the thermostatic cartridge over time.
- If you experience inconsistent temperature or reduced flow, the cartridge may need cleaning or replacement. This should be performed by a qualified plumber.
Troubleshooting
If you encounter issues with your thermostatic valve, refer to the common problems and solutions below. For complex issues, contact a qualified plumber.
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent water temperature | Fluctuating water pressure; clogged thermostatic cartridge; incorrect installation of hot/cold lines. | Check water pressure; have a plumber inspect/clean/replace the cartridge; verify hot/cold connections. |
| No hot or cold water | Supply valve closed; blockage in supply line; faulty thermostatic cartridge. | Ensure supply valves are open; check for blockages; consult a plumber for cartridge inspection. |
| Low water flow | Low water pressure; clogged aerator (if applicable to connected outlet); debris in valve. | Check household water pressure; clean connected outlet aerators; have a plumber inspect the valve for debris. |
| Water leaks from trim plate | Improperly sealed escutcheon; damaged O-rings or seals in the rough-in body. | Ensure escutcheon is correctly installed and sealed; contact a plumber to inspect internal seals. |
