Installation Guide
This section outlines the steps for installing your Roca Logica-N Built-in Mixer Tap. This is a wall-mounted, built-in installation and requires careful attention to plumbing and wall preparation. It is recommended to have this installed by a professional plumber.
Tools and Materials Required (Not Included):
- Rocabox 525869403 (essential for installation)
- Adjustable wrench
- Screwdriver (Phillips/Flathead as needed)
- Measuring tape
- Level
- Drill with appropriate bits
- Sealant/Teflon tape
- Pipe cutter (if modifying existing plumbing)
Installation Steps:
- Prepare the Installation Area:
Ensure the main water supply to the bathroom is turned off. Identify the desired location for the mixer tap on the wall. This unit is designed for built-in installation, meaning the main body will be concealed within the wall.
- Install the Rocabox (Sold Separately):
The Roca Logica-N mixer tap requires the Rocabox 525869403 for its concealed installation. Follow the specific instructions provided with the Rocabox for its proper mounting and connection to your hot and cold water lines within the wall cavity. Ensure the Rocabox is securely fixed and level.
- Connect the Mixer Tap to the Rocabox:
Once the Rocabox is installed, carefully connect the mixer tap unit to the designated outlets on the Rocabox. Ensure all connections are tight and sealed using appropriate plumbing tape or sealant to prevent leaks. The mixer tap unit will typically slide into or attach to the Rocabox from the front.
- Secure the Faceplate/Escutcheon:
Position the decorative faceplate (escutcheon) over the installed mixer unit, aligning it with the mounting points. Secure the faceplate to the wall or the Rocabox using the provided screws. Ensure it is flush against the wall and covers the opening neatly.
- Install the Handle:
Attach the single lever handle to the mixer spindle. Typically, this involves pushing the handle onto the spindle and securing it with a small set screw, often located on the underside of the handle. Cover the set screw with the decorative cap if provided.
- Test for Leaks and Functionality:
Slowly turn the main water supply back on. Check all connections for any signs of leaks. Operate the mixer handle to test the flow of hot and cold water and ensure proper mixing. Adjust water temperature and flow as needed.
Operating Instructions
The Roca Logica-N mixer tap features a single lever for controlling both water flow and temperature.
- Water Flow Control:
To turn the water on, lift the lever upwards. The further you lift it, the greater the water flow. To turn the water off, push the lever downwards until it is in the closed position.
- Temperature Control:
To adjust the water temperature, move the lever horizontally. Moving the lever to the left typically increases the hot water proportion, while moving it to the right increases the cold water proportion. Find your desired temperature by adjusting the lever's horizontal position.
Maintenance and Care
Proper care will ensure the longevity and appearance of your Roca Logica-N mixer tap.
- Cleaning:
Clean the chrome finish regularly with a soft cloth and mild soap and water. Rinse thoroughly with clean water and dry immediately to prevent water spots. Do not use abrasive sponges, scouring pads, or harsh chemical cleaners (e.g., bleach, ammonia-based products, or acidic cleaners) as these can damage the chrome finish.
- Hard Water Areas:
In areas with hard water, limescale deposits may build up. Use a descaling solution specifically designed for bathroom fixtures, following the product's instructions carefully. Ensure the solution does not remain on the surface for too long and rinse thoroughly.
- Leak Prevention:
Periodically check for any signs of leaks around the base of the tap or connections. Address any leaks promptly to prevent water damage.
