4.2 Installation Steps

1. Prepare the Installation Area: Ensure the mounting surface is clean and dry. Turn off the main water supply to prevent water flow during installation.
2. Insert the Tap: Place the tap into the single mounting hole on your sink or countertop. Ensure any base gaskets are correctly positioned between the tap and the surface.
3. Secure the Tap: From underneath the sink, slide the mounting bracket over the threaded rod(s) of the tap. Secure it with the provided washer and nut. Tighten firmly but do not overtighten to avoid damaging the sink or tap.
4. Connect the Water Supply: Attach the 350 mm connection hose to the tap's inlet. Use plumber's tape on the threads for a watertight seal. Connect the other end of the hose to your cold water supply valve. Ensure all connections are hand-tightened, then use a wrench for a final quarter-turn.
5. Check for Leaks: Slowly turn on the main water supply. Check all connections for any signs of leaks. If leaks occur, tighten the connections slightly until they stop.
6. Flush the System: Open the tap and let water run for a few minutes to flush out any debris from the pipes.

Regular cleaning and maintenance will help preserve the appearance and functionality of your tap.

• Cleaning the Surface: Clean the chrome-plated surface regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
• Do Not Use: Avoid using abrasive sponges, scouring pads, harsh detergents, or cleaners containing alcohol, ammonia, or phosphoric acid, as these can damage the chrome finish.
• Aerator Maintenance: Periodically unscrew the aerator from the spout and clean any mineral deposits or debris. Rinse it under running water and reattach it.
• Ceramic Cartridge: The tap features wear-resistant ceramic sealing discs. If you experience persistent dripping or difficulty controlling water flow, the ceramic cartridge may need replacement. This is a task best performed by a qualified plumber.
