The Methven AIO Shower Mixer with Diverter is a plumbing fixture designed for controlling water flow and temperature in a shower system, incorporating a diverter function to switch between different water outlets. This installation guide provides comprehensive instructions for setting up and maintaining the device, along with crucial technical specifications and general advice for optimal performance and longevity.

Function Description:

The primary function of the AIO Shower Mixer is to mix hot and cold water to achieve a desired temperature and to control the flow of this mixed water to the shower outlets. The integrated diverter allows the user to switch the water flow between two different outlets, such as a main showerhead and a handheld shower or body jets. The mixer features a cartridge lever for temperature and flow control, and a diverter knob for outlet selection. The installation process involves securing the mixer body within the wall cavity, connecting hot and cold water supplies, and then attaching the faceplate, diverter knob, and handle.

Important Technical Specifications:

• Operating Pressure:
  • Minimum: 150kPa / 1.5 bar
  • Maximum: 1000kPa / 10 bar (Note: Regional specific regulations may apply, affecting the warranty.)
  • Optimum: 150kPa / 1.5 bar - 500kPa / 5 bar
• Operating Temperature:
  • Hot: Maximum 80°C (Note: Regional specific regulations may apply, affecting the warranty.)
  • Cold: Minimum 5°C
• Inlet Connections: All 1/2" BSP
• Mounting Dimensions:
  • Wall lining hole cut or finished: Ø50-55mm (for the main body) and Ø55-60mm (for the faceplate).
  • Optimum distance from mounting surface to finished wall surface: 65mm ±10.
  • The faceplate locator fits into a small hole on the faceplate, ensuring correct orientation.

Usage Features:

• Temperature and Flow Control: The main handle, which pushes onto the cartridge lever, allows users to adjust both the water temperature and flow rate.
• Diverter Function: A dedicated diverter knob enables switching water flow between two outlets. The knob is designed to be screwed onto a brass diverter spindle. For proper operation, the knob should be screwed on until it touches the faceplate, then unscrewed approximately 1mm (one turn) so that its handle points vertically upwards.
• Secure Fastening: Both the diverter knob and the main handle are secured with grub screws, tightened with a hex key, to prevent accidental detachment during use.
• Aesthetic Design: The mixer features a clean, modern aesthetic with a faceplate that sits flush against the finished wall surface. A silicone seal is recommended between the faceplate and the wall to ensure a waterproof installation.

Maintenance Features:

• Cleaning: The product should be cleaned regularly using contamination-free warm soapy water and a damp soft cloth.
• Prohibited Cleaning Agents: Abrasives or abrasive cleaning agents must never be used, as they can damage the product's finish.
• Durability: Methven warrants this product against manufacturing defects, provided it is used under the general operating conditions specified in the instruction sheet. Regional regulations may affect the warranty, so customers are advised to consult www.methven.com or contact customer service for full details.
• Installation Best Practices (contributing to longevity):
  • Installation by a licensed plumber is recommended to ensure compliance with regional regulations.
  • Hydrostatic testing with the mixer installed is discouraged to prevent damage to the ceramic cartridge.
  • All pipework must be thoroughly flushed prior to installation to remove debris.
  • In-line filters should be fitted on both hot and cold supplies to protect the ceramic cartridge from foreign particles.
  • The ceramic cartridge should not be removed during installation.
  • All connections must be checked for leaks after installation.
  • For uncontrolled heating systems (e.g., wet-backs, solar units), a suitable tempering valve is required.
  • The installer is responsible for ensuring a waterproof seal between the product and the mounting surface, with silicone recommended if there is any doubt about the seal quality.

The Methven AIO Shower Mixer with Diverter is designed for reliable performance and ease of use, emphasizing proper installation and maintenance for a long-lasting shower experience.
