4. Setup and Installation

The Cornat TEC301101 machine tap is designed for wall mounting and features a 1/2" external thread for water supply connection, a 3/4" internal thread for hose connection, and a 14 mm nozzle.

1. Prepare the Installation Area: Ensure the main water supply to the installation point is completely shut off. Drain any residual water from the pipes.
2. Mount the Tap: The tap is designed for wall mounting. Securely attach the tap to the wall using appropriate mounting hardware (not included, typically supplied with the wall connection). Ensure the 1/2" external thread is ready for connection to the water supply pipe.
3. Connect to Water Supply: Apply PTFE tape or thread sealant to the 1/2" external thread of the tap. Connect the tap to the existing 1/2" internal thread water supply pipe on the wall. Tighten firmly but do not overtighten.
4. Connect Appliance Hose: The tap features a 3/4" internal thread for connecting the hose of your washing machine or dishwasher. Ensure the hose has a rubber washer for a watertight seal. Screw the appliance hose onto the 3/4" thread of the tap and tighten by hand, then a quarter turn with a wrench if necessary.
5. Check for Leaks: Slowly turn on the main water supply. Carefully inspect all connections for any signs of leaks. If leaks are detected, shut off the water supply and re-tighten the connections.

5. Operating Instructions

The Cornat TEC301101 machine tap is simple to operate using its locking lever.

1. To Open Water Flow: Turn the locking lever counter-clockwise. The further you turn, the greater the water flow.
2. To Close Water Flow: Turn the locking lever clockwise until it is fully shut. This will stop the water supply to the connected appliance.
3. Non-Return Valve: The integrated non-return valve automatically prevents water from flowing back into the main supply, ensuring hygiene and compliance with plumbing regulations.
4. Aerator: The aerator at the nozzle mixes air with the water, providing a smooth, splash-free flow.

6. Maintenance

Regular maintenance will ensure the longevity and optimal performance of your Cornat TEC301101 machine tap.

• Cleaning: Clean the tap regularly with a soft cloth and mild, non-abrasive cleaning agents. Avoid using harsh chemicals, abrasive sponges, or scouring powders, as these can damage the matte chrome finish.
• Leak Checks: Periodically inspect all connection points for any signs of leaks. If a leak is detected, shut off the water supply and gently tighten the connection. If the leak persists, the washer or seal may need replacement.
• Aerator Cleaning: If water flow becomes weak or irregular, the aerator may be clogged. Unscrew the aerator from the nozzle, clean it under running water to remove any debris or limescale, and then reattach it.

7. Troubleshooting

This section addresses common issues you might encounter with your machine tap.

• No Water Flow:
  • Ensure the main water supply to your property is turned on.
  • Verify that the tap's locking lever is fully open (turned counter-clockwise).
  • Check for any blockages in the water supply line or the tap's aerator.
• Leaks at Connections:
  • Shut off the main water supply.
  • Gently tighten the connections where the leak is observed. Do not overtighten.
  • If tightening does not resolve the issue, the rubber washer or seal at the connection point may be worn or improperly seated. Replace if necessary.
• Weak or Irregular Water Flow:
  • The aerator might be clogged with debris or limescale. Refer to the "Aerator Cleaning" step in the Maintenance section.
  • Check the water pressure from your main supply.
