Honeywell FK06 Pressure Reducing Valve with Sediment Filter

Introduction

This instruction manual provides essential information for the proper installation, operation, and maintenance of your Honeywell FK06 Pressure Reducing Valve (PRV) with an integrated Sediment Filter. Please read this manual thoroughly before installation and retain it for future reference.

Safety Information

WARNING: This product may be subject to California Proposition 65 rules and regulations. For more information, please visit www.P65Warnings.ca.gov.

Always ensure that installation and maintenance are performed by qualified personnel in accordance with local plumbing codes and regulations. Turn off the main water supply before beginning any work on the plumbing system.

Product Overview

The Honeywell FK06 is a low-lead pressure regulating filter combination valve designed to protect water systems from excessive pressure and filter out sediment. It combines the functions of a pressure reducing valve and a sediment filter into a single compact unit, suitable for industrial, commercial, irrigation, and point-of-entry applications.

Figure 1: Honeywell FK06 Pressure Reducing Valve with Sediment Filter. This image shows the brass valve body with a black pressure adjustment knob on top, a clear filter bowl below, and threaded connections on both sides for installation into a water line. A small drain valve is visible at the bottom of the filter bowl.

Key Features:

• Integrated pressure reducing valve and sediment filter.
• Low-lead brass construction.
• Adjustable outlet pressure.
• Clear filter bowl for easy inspection of sediment.
• Suitable for various applications including industrial and commercial use.

Specifications

Setup and Installation

1. Preparation: Turn off the main water supply to the property. Drain the water lines to relieve pressure.
2. Location: Install the FK06 in a horizontal pipe run with the filter bowl facing downwards. Ensure there is sufficient clearance below the filter bowl for maintenance.
3. Connection: The valve features 1-inch NPT threaded connections. Apply appropriate thread sealant (e.g., PTFE tape or pipe dope) to the male threads of the connecting pipes. Connect the FK06 to the water line, ensuring the flow arrow on the valve body matches the direction of water flow.
4. Tightening: Tighten connections securely but do not overtighten, as this can damage the threads or valve body.
5. Water Supply Restoration: Slowly turn on the main water supply, checking for leaks.
6. Pressure Adjustment: The outlet pressure can be adjusted using the black knob on top of the valve. Turn clockwise to increase pressure, counter-clockwise to decrease pressure. Use a pressure gauge downstream of the valve to monitor the adjusted pressure.

It is recommended to have a qualified plumber perform the installation to ensure compliance with all local codes and proper functionality.

Operating Instructions

Once installed and the desired outlet pressure is set, the Honeywell FK06 operates automatically to maintain a consistent downstream pressure and filter sediment from the water supply. No continuous user intervention is required for its primary function.

• Pressure Monitoring: Periodically check the pressure gauge (if installed) downstream of the PRV to ensure the desired pressure is maintained.
• Sediment Observation: The clear filter bowl allows for visual inspection of accumulated sediment.

Maintenance

Regular maintenance of the sediment filter is crucial for optimal performance and longevity of the FK06 unit.

1. Filter Cleaning/Flushing:
   • Observe the clear filter bowl. When a significant amount of sediment is visible, or if water flow appears reduced, the filter requires cleaning.
   • To flush the filter, open the drain valve located at the bottom of the filter bowl. Allow water to flow out until the sediment is cleared.
   • Close the drain valve once flushing is complete.
2. Deep Cleaning (if necessary): For heavy sediment buildup, it may be necessary to remove the filter bowl and clean the screen manually.
   • Turn off the main water supply and relieve pressure.
   • Unscrew the filter bowl from the valve body.
   • Remove the filter screen and rinse it thoroughly under running water. A soft brush can be used to dislodge stubborn particles.
   • Inspect the O-rings and gaskets for wear or damage. Replace if necessary.
   • Reassemble the filter bowl and screen, ensuring O-rings are properly seated.
   • Slowly restore water supply and check for leaks.
3. Annual Inspection: It is recommended to inspect the entire unit annually for any signs of wear, corrosion, or leaks.

Troubleshooting

• Low Water Pressure:
  • Check if the filter screen is clogged with sediment. Perform filter cleaning as described in the Maintenance section.
  • Verify the pressure setting. Adjust the black knob clockwise to increase outlet pressure.
  • Ensure the main water supply is fully open.
• High Water Pressure:
  • Verify the pressure setting. Adjust the black knob counter-clockwise to decrease outlet pressure.
  • Check for debris obstructing the PRV mechanism. If suspected, professional service may be required.
• Leaks:
  • Check all threaded connections for proper tightening and sealant.
  • Inspect the filter bowl O-ring for proper seating or damage. Replace if necessary.
  • If leaks persist from the valve body, the unit may require professional repair or replacement.
