This document describes the AXOR One series of concealed thermostats, specifically models 45712XX7 and 45713XX7, which are designed for bathing, hygiene, and body cleaning purposes. It provides installation instructions, technical specifications, usage features, and maintenance guidelines.
Function Description
The AXOR One concealed thermostat is a control unit for water temperature and flow in a shower or bath system. It features a thermostatic cartridge that allows users to set and maintain a desired water temperature, with a safety function to prevent scalding by pre-setting a maximum temperature (e.g., 42°C). The device includes controls for adjusting water flow and selecting different spray functions, depending on the connected shower components. It is designed to prevent backflow and is suitable for use with drinking water.

Maintenance Features
- Regular Cleaning: The document emphasizes the importance of regular cleaning to prevent limescale buildup and maintain the product's appearance and functionality.
- Cleaning Guidelines:
- Only use cleaning materials specifically designed for this type of application.
- Avoid cleaning agents containing hydrochloric acid, formic acid, chlorine, lye, or acetic acid, as these can cause significant damage.
- Phosphorus acidic cleaners should only be used conditionally.
- Do not mix different cleaning agents.
- Avoid abrasive cleaning materials or appliances (e.g., powders, sponges, micro-fiber cloths).
- Follow the cleaning agent manufacturer's instructions regarding dosage and contact time.
- When using spray cleaners, apply the solution to a soft cloth or sponge first, rather than directly onto the product, to prevent it from entering openings and causing damage.
- Rinse thoroughly with clean water after cleaning to remove any residue.
- Do not use steam cleaners, as high temperatures can damage the product.
- Backflow Preventer Check: The check valves must be inspected regularly (at least once a year) according to EN 806-5 and national/regional regulations.
- Filter Cleaning: The regulator filter and shower filter seal should be cleaned if the water flow is insufficient.
- Thermostatic Cartridge Maintenance: If temperature regulation is not possible or the water temperature does not match the set temperature, the thermostatic cartridge may need adjustment, cleaning, or replacement if calcified.
- Troubleshooting: The manual provides a troubleshooting guide for common issues such as insufficient water flow, crossflow, incorrect water temperature, and non-functional instantaneous heaters, along with suggested remedies.
- Spare Parts: A detailed exploded view with part numbers is provided for ordering spare parts, ensuring long-term serviceability.
- Warranty: Hansgrohe offers a 5-year warranty against production faults, provided the product has been installed and maintained according to the instructions. Damage caused by improper treatment is not covered.
