Setup and Installation

This product is designed for easy installation as a replacement or new component in compatible GROHE thermostatic mixers. Professional installation is recommended for optimal results.

Required Tools (Not Included):

• Adjustable wrench or appropriate spanner
• Screwdriver (if applicable for securing)
• Cleaning cloth

Installation Steps:

1. Turn off Water Supply: Locate the main water shut-off valve for your bathroom or the specific fixture and turn it off completely to prevent water flow during installation.
2. Remove Existing Dial (if applicable): Carefully remove any existing temperature control dial or cover. This may involve unscrewing a small set screw or gently prying off a cap.
3. Clean Mounting Surface: Ensure the mounting surface on the thermostatic mixer is clean and free of debris or old sealant.
4. Position the New Dial: Align the GROHE Grohtherm 1000 Dial Control Temperature (model 47973000) with the spindle of the thermostatic mixer. Ensure it seats correctly.
5. Secure the Dial: Depending on the mixer model, secure the dial using the provided set screw or by pushing it firmly into place until it clicks. Refer to your specific thermostatic mixer's manual for precise securing methods.
6. Test Functionality: Slowly turn the water supply back on. Test the dial by rotating it to adjust the temperature. Check for any leaks around the installation area.

If you encounter any difficulties during installation, consult a qualified plumber.

Operating Instructions

The GROHE Grohtherm 1000 Dial Control Temperature allows for precise adjustment of water temperature in your shower or bath.

Temperature Adjustment:

• Rotate the Dial: Turn the dial clockwise to decrease the water temperature and counter-clockwise to increase it.
• Temperature Markings: The dial typically features clear markings or symbols indicating temperature ranges (e.g., cooler to warmer, or specific degree markings).
• Safety Stop: Many GROHE thermostatic mixers include a safety stop feature, often at 38°C (100°F), to prevent accidental scalding. To exceed this temperature, you may need to press a button or override the stop while turning the dial. Refer to your specific mixer's manual for details on this feature.

Always test the water temperature with your hand before stepping into the shower or bath to ensure it is comfortable and safe.

Maintenance and Care

Proper care will help maintain the appearance and functionality of your GROHE Grohtherm 1000 Dial Control Temperature.

Cleaning:

• Regular Cleaning: Clean the chrome surface regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes.
• Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, or cleaners containing alcohol, ammonia, bleach, or phosphoric acid, as these can damage the chrome finish.
• Rinse and Dry: After cleaning, rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.

General Care:

• Avoid impacts or excessive force on the dial, which could cause damage.
• Ensure the dial turns smoothly. If it becomes stiff, consult the troubleshooting section or a professional.

Troubleshooting

If you experience issues with your GROHE Grohtherm 1000 Dial Control Temperature, consider the following common solutions:

• Dial is Stiff or Hard to Turn:
  • Check for debris: Ensure no foreign objects are lodged around the base of the dial.
  • Mineral buildup: Hard water can cause mineral deposits. Gentle cleaning around the base of the dial may help. If the issue persists, the internal cartridge of the thermostatic mixer may require servicing by a professional.
• Temperature Not Adjusting Correctly:
  • Water supply: Verify that both hot and cold water supplies are fully open to the mixer.
  • Mixer calibration: The thermostatic mixer itself may need recalibration. This is typically done by a professional and is not related to the dial control itself.
  • Internal component wear: If the dial is turning freely but temperature does not change, the internal thermostatic cartridge may be worn or faulty. This requires professional replacement of the cartridge, not the dial.
• Dial is Loose:
  • Tighten set screw: If your dial uses a set screw, gently tighten it. Do not overtighten.
  • Re-seat dial: Remove the dial and re-seat it firmly onto the spindle.

For issues beyond these basic troubleshooting steps, it is recommended to contact GROHE customer support or a qualified plumbing professional.
