This pot filler faucet is designed for cold water connection only. It is intended for installation above sinks or stoves to provide a convenient water source for pots and pans. Before beginning installation, ensure that plasterboard walls have appropriate reinforcement to support the weight of the faucet. The recommended hole size for installation is 1 inch, and the unit uses 1/2 inch IPS inlets.
Installation Steps



- Prepare Supply: Wrap plumber tape around pipe threads and connect to the 1/2 inch IPS supply line.
- Marking: Push the flange onto the pot filler and mark the locating hole on the wall.
- Drilling: Drill holes (15/64 inch or 6mm) and insert plugs.
- Mounting: Wrap plumber tape around pipe threads. Install the gasket and the flange using the 4 provided screws.
- Final Assembly: Place the flange trim onto the faucet. Thread the faucet onto the pipe and tighten securely, but do not overtighten.
- Securing: Screw the pot filler into place and use a 1.5mm allen wrench to fasten the pot filler to the flange.
Flushing and Maintenance
Flushing: Before regular use, remove the aerator and turn the faucet handles to the full open position. Turn on the cold water supply and flush the water lines for one minute to remove debris that could damage internal parts. Check all connections for leaks and re-tighten if necessary.

Cleaning: The finish is durable but can be damaged by harsh abrasives or polish. Clean the faucet by wiping gently with a damp cloth and blotting dry with a soft towel.
Troubleshooting
If the faucet leaks from the spout or handle, the valve cartridge may need replacement:
- Remove the handle cap, stick, and screw.
- Unscrew and replace the valve cartridge using a 1.5mm hex key.
- Assemble in reverse order, ensuring handles are lined up with valves in the closed position before pushing them into place.
If water flow is unsatisfactory due to low water pressure, replace the aerator to improve flow.
