4. Installation Guide

Before beginning installation, ensure you have the necessary tools: adjustable wrench, flathead screwdriver, Phillips head screwdriver, and a clean cloth.

Safety Precautions:

• Always turn off the main water supply to the faucet before starting any work.
• Cover the drain opening to prevent small parts from falling into the drain.
• Wear appropriate personal protective equipment, such as gloves and eye protection.

Step-by-Step Installation:

1. Turn Off Water Supply: Locate the hot and cold water shut-off valves under the sink and turn them clockwise until the water flow stops completely. Open the faucet handle to relieve any remaining pressure.
2. Remove Faucet Handle: Depending on your faucet model (DF-NMK530 or DF-NMK531), carefully remove the decorative cap (if present) and unscrew the handle screw. Lift the handle off.
3. Access the Cartridge: Remove any retaining nuts or clips that secure the existing cartridge. You may need an adjustable wrench for the retaining nut.
4. Remove Old Cartridge: Gently pull the old ceramic disc cartridge straight up and out of the faucet body. Note its orientation for reference.
5. Clean Faucet Body: Inspect the faucet body for any debris or mineral buildup. Clean the area thoroughly with a cloth.
6. Insert New Cartridge: Align the new Dura Faucet DF-RK602 cartridge with the slots in the faucet body. Ensure it is seated correctly and fully inserted. The flat side of the cartridge should face the front of the faucet.
7. Secure Cartridge: Reinstall the retaining nut or clips, tightening them securely but do not overtighten.
8. Reattach Handle: Place the faucet handle back onto the cartridge stem, align it properly, and secure it with the handle screw. Reattach any decorative caps.
9. Restore Water Supply: Slowly turn the hot and cold water shut-off valves counter-clockwise to restore water flow.
10. Check for Leaks: Turn on the faucet and check for any leaks around the base of the handle or the faucet body. Test both hot and cold water flow.

5. Operating Instructions

Once installed, the Dura Faucet Ceramic Disc Cartridge operates seamlessly within your DF-NMK530 or DF-NMK531 faucet. The ceramic disc design allows for precise control of water temperature and flow with a single lever handle.

• Water Flow Control: Lift the handle to increase water flow; push down to decrease and shut off.
• Temperature Control: Move the handle left for hot water and right for cold water. The ceramic discs mix the water to achieve the desired temperature.

6. Maintenance

The Dura Faucet Ceramic Disc Cartridge is designed for minimal maintenance. However, periodic checks can extend its lifespan and ensure optimal performance.

• Cleaning: If water flow becomes restricted or erratic, it may indicate mineral buildup. Turn off the water supply and carefully remove the cartridge as per installation steps. Rinse the cartridge under running water to dislodge any debris. Do not use harsh chemicals or abrasive cleaners on the cartridge.
• Leak Checks: Periodically check around the faucet base and connections for any signs of leaks. Address any leaks promptly by ensuring connections are tight or by re-seating the cartridge if necessary.
• Handle Operation: If the handle becomes stiff or difficult to move, ensure the retaining nut is not overtightened. The ceramic discs are self-lubricating and should provide smooth operation.
