Configuration et installation
The IMEX GTA052 ASSEN shower faucet is designed for built-in installation. This requires careful planning and execution, typically involving recessing the main mixer body and associated plumbing within the wall. It is highly recommended that installation be performed by a qualified plumber to ensure compliance with local building codes and proper functionality.
- Préparez le mur : Create the necessary recess in the wall for the 2-way brass body with its registration box. Ensure adequate space for plumbing connections and future access if required.
- Install Mixer Body: Securely mount the built-in mixer body within the wall recess, ensuring it is level and at the correct depth relative to the finished wall surface. Connect the hot and cold water supply lines to the designated inlets.
- Prises de connexion : Connect the two outlets from the mixer body to the shower head and the hand shower outlet/holder respectively. The brass wall outlet tube should be installed for the main shower head.
- Installer le pommeau de douche : Attach the stainless steel round shower head (Ø25 cm) to the wall outlet tube. Ensure a watertight seal.
- Install Hand Shower Components: Mount the hand shower holder with water outlet at a convenient height. Connect the PVC hose (1.5 m) to the outlet and the round hand shower.
- Assemblage final : Once plumbing connections are complete and tested for leaks, install the round escutcheons (Ø 80 mm) and the thermostatic handle and diverter handle onto their respective shafts.
- Fonctionnalité de test : Turn on the main water supply and test all functions, checking for leaks, proper water flow, and temperature control.

Mode d'emploi
Your IMEX GTA052 ASSEN shower faucet features a thermostatic control for precise temperature management and a 2-way diverter to switch between the main shower head and the hand shower.
- Réglage de la température : Use the thermostatic handle (typically on one side) to set your desired water temperature. The thermostatic cartridge will automatically mix hot and cold water to maintain this temperature, even if water pressure fluctuates.
- Water Flow Control / Diverter: Use the other handle to turn the water on/off and to select the water outlet.
- Rotate the handle to control the water flow rate.
- Push or pull, or rotate the handle to switch between the main shower head and the hand shower. Refer to the markings on the escutcheon for specific positions.
- Débit moyen : The system provides an average flow rate of 20 liters per minute, ensuring a comfortable shower experience.

Entretien
Regular maintenance will help preserve the appearance and functionality of your IMEX GTA052 ASSEN shower faucet.
- Nettoyage des surfaces chromées : Clean the chrome finish regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome. Avoid using abrasive sponges, harsh chemicals, or acidic cleaners, as these can damage the finish. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Thermostatic Cartridge (TURN CLEAN SYSTEM): The integrated TURN CLEAN SYSTEM thermostatic cartridge is self-cleaning, which helps prevent limescale buildup and ensures consistent temperature control. No special user maintenance is typically required for the cartridge itself, beyond regular use.
- Anti-Limescale Shower Head: The stainless steel shower head features anti-limescale nozzles. Periodically rub the silicone nozzles to dislodge any mineral deposits. For more stubborn buildup, a mild descaling solution can be used, followed by thorough rinsing.
- Hose and Hand Shower: Clean the PVC hose and hand shower with a soft cloth and mild soap. Check the hose periodically for any signs of wear or damage.
