Setup and Installation
- Preparation: Turn off the main water supply to the fixture where the cartridge will be installed. Drain any remaining water from the pipes.
- Access the Cartridge: Depending on your specific shower unit (e.g., Avon 21 self-closing shower), you will need to remove the handle, trim, and any retaining nuts or screws to access the existing cartridge. Refer to your shower unit's specific instructions for disassembly.
- Remove Old Cartridge: Carefully extract the old metering valve cartridge. Note its orientation for correct installation of the new one.
- Install New Cartridge: Insert the Ideal Standard A862288NU cartridge into the valve body, ensuring it is seated correctly and oriented as the old one was.
- Secure Cartridge: Re-install any retaining nuts, screws, or clips that hold the cartridge in place. Do not overtighten.
- Reassemble Fixture: Reattach the trim and handle components.
- Test: Slowly turn the main water supply back on. Check for any leaks around the newly installed cartridge. Operate the shower to ensure proper function and water flow.
Important Note: This cartridge is specifically designed for Avon 21 self-closing showers. It is not compatible with Avin 21 self-closing taps.
Operating Instructions
Once installed, the metering valve cartridge controls the flow duration of water in your self-closing shower. When the shower is activated (e.g., by pressing a button or lever), the cartridge allows a measured amount of water to flow before automatically shutting off. The duration of flow is pre-set by the design of the metering valve.
- Activation: Press or activate the shower control.
- Water Flow: Water will flow for a pre-determined period.
- Automatic Shut-off: The cartridge will automatically close the water flow after the cycle completes.
Maintenance
The Ideal Standard A862288NU metering valve cartridge is designed for long-term reliability. Regular maintenance is generally not required for the cartridge itself, beyond ensuring proper installation and checking for leaks.
- Leak Checks: Periodically inspect the shower unit for any signs of water leaks around the cartridge area. Address any leaks promptly.
- Cleaning: Clean the exterior of the shower fixture according to the manufacturer's instructions for the shower unit. Avoid harsh chemicals that could damage seals or finishes.
- Water Quality: In areas with hard water, mineral deposits can sometimes affect valve performance over time. If you experience inconsistent flow or premature shut-off, the cartridge may need inspection or replacement.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Water continues to flow after activation cycle. | Faulty cartridge seal or internal mechanism. | Replace the metering valve cartridge. |
