2. Safety Information

• Always shut off the main water supply before beginning any installation or maintenance.
• Wear appropriate personal protective equipment (PPE), such as safety glasses and gloves.
• Ensure all connections are properly sealed to prevent leaks.
• Consult local plumbing codes and regulations for proper installation procedures.
• If you are unsure about any part of the installation, consult a qualified plumber.

3. Package Contents

Verify that all components are present before beginning installation:

• 1x Apollo 3/4" Bronze Double Union Threaded Water Pressure Regulator
• 1x Integrated Pressure Gauge

4. Installation

This regulator features a double union PEX-A (cold expansion) barb design for simplified installation in PEX-A piping systems. Ensure the regulator is installed in the correct flow direction, indicated by an arrow on the body.

1. Prepare the Installation Site: Turn off the main water supply. Drain the water lines to relieve pressure. Select a suitable location for the regulator, typically after the main shut-off valve and before any branch lines.
2. Cut and Prepare PEX-A Piping: Cut the PEX-A pipe to the required length, ensuring clean, square cuts. Prepare the pipe ends for cold expansion connections according to PEX-A system manufacturer guidelines.
3. Connect the Regulator:
   • Apply appropriate thread sealant (e.g., Teflon tape or pipe dope) to the male threads of the PEX-A fittings.
   • Thread the PEX-A fittings onto the double union ends of the regulator. Ensure the flow arrow on the regulator body points in the direction of water flow into the building.
   • Tighten the union nuts securely, but do not overtighten.
   • Perform cold expansion connections on the PEX-A pipe ends to the fittings according to PEX-A system manufacturer instructions.
4. Install Pressure Gauge: The pressure gauge is typically pre-installed. Ensure it is securely threaded into the designated port on the regulator body.
5. Restore Water Supply and Check for Leaks: Slowly turn on the main water supply. Carefully inspect all connections for any signs of leaks. Tighten connections as necessary.

5. Operating Instructions

The regulator is factory-set at 50 psi and is adjustable from 15 psi to 75 psi. No special tools are required for adjustment.

1. Check Current Pressure: Observe the reading on the integrated pressure gauge. The gauge is color-coded to indicate pressure ranges (e.g., Low, Optimal, Excessive).
2. Adjusting Pressure:
   • To increase pressure: Turn the yellow adjustment handle clockwise.
   • To decrease pressure: Turn the yellow adjustment handle counter-clockwise.
   • Make small adjustments and allow the system pressure to stabilize before re-checking the gauge.
3. Confirm Setting: Once the desired pressure is achieved (typically between 50-60 psi for most residential applications), confirm the reading on the gauge.

6. Maintenance

The Apollo Water Pressure Regulator is designed for minimal maintenance. Regular checks can help ensure optimal performance.

• Periodic Pressure Check: Periodically check the pressure gauge to ensure the system pressure remains at the desired setting. Fluctuations may indicate a need for adjustment or inspection.
• Leak Inspection: Annually inspect the regulator and connections for any signs of leaks or corrosion.
• Cleaning: Clean the exterior of the regulator with a damp cloth as needed. Do not use harsh chemicals.
• Sediment Filter (Optional): If your water supply contains significant sediment, consider installing a sediment filter upstream of the pressure regulator to prevent internal clogging.
