5. Setup and Installation
This thermostatic mixer tap is designed for wall-mount installation. It is recommended that installation be carried out by a certified plumber.
Installation Steps:
- Prepare the Installation Area: Ensure the wall connections for hot and cold water are correctly spaced and aligned. The standard distance between centers is typically 150mm.
- Install S-Unions: Apply PTFE tape to the threaded ends of the S-unions and screw them into the wall connections. Adjust their depth and angle until they are level and the correct distance apart for the tap.
- Attach Escutcheons: Slide the decorative escutcheons over the S-unions, flush against the wall.
- Connect the Mixer Tap: Place the rubber washers into the nuts of the mixer tap. Carefully align the tap with the S-unions and tighten the nuts by hand, then use a wrench to secure them, being careful not to overtighten.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks.

7. Maintenance and Cleaning
To maintain the appearance and functionality of your GRIFEMA G13005 thermostatic mixer tap, follow these guidelines:
- Regular Cleaning: Clean the tap 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 sponges, scouring pads, or cleaners containing alcohol, ammonia, bleach, or phosphoric acid, as these can damage the chrome surface.
- Rinse and Dry: After cleaning, rinse the tap thoroughly with clean water and dry it immediately with a soft cloth to prevent water spots and maintain its high shiny chrome coating.
