4. Installation Instructions

Important Safety Note: Before beginning any plumbing work, always turn off the main water supply to prevent leaks or damage. It is recommended to consult a qualified plumber if you are unsure about any steps.

4.1. Preparation

1. Turn off the water supply to the faucet at the main shut-off valve.
2. Carefully remove the existing mixer cap and pressure balancing unit from the valve body.
3. Clean any debris or accumulated scale from inside the pipe and the valve body using sandpaper or a suitable cleaning tool. This step is critical for preventing future leaks and ensuring proper sealing.
4. Ensure all O-rings are in place and lubricate them with plumbing grease before installation. This facilitates a proper seal and prevents damage during assembly.

4.2. Installing the Pressure Balancing Unit

1. Place the lubricated O-rings into their designated grooves on the GP500520 Pressure Balancing Unit.
2. Carefully insert the GP500520 Pressure Balancing Unit into the valve body. Ensure it is firmly placed and do not rotate it in the pipeline during installation to avoid dislodging O-rings.

4.3. Installing the Mixer Cap

1. Slide the O-ring and upper limit stop onto the valve stem of the GP77886 Mixer Cap.
2. Align the mixer cap with the valve body and secure it with the provided cap screws.

4.4. Important Installation Notes

• O-rings must be installed correctly on both the mixer cap and pressure balancing unit. Apply lubricant if necessary.
• Do not rotate the pressure balancing unit within the pipeline during installation to prevent O-rings from falling off.
• If the mixer cap needs replacement, it is recommended to replace the pressure balancing unit simultaneously, as a faulty pressure balancing unit can also cause leakage.
• Always clean any debris in the pipe before installation, as this can lead to leaks.

5. Operation

5.1. Temperature Limiting Adjustment

The valve stem allows for adjustment of water temperature by changing the position of an internal barrier plate, which mixes hot and cold water in different proportions.

1. Slide the O-ring and upper limit stop into the valve stem.
2. Place the handle onto the stem and turn it clockwise to the desired temperature.
3. Use a thermometer to measure the water temperature from the stream. Adjust the handle until the desired temperature is reached.
4. Rotate the lower limit stop until it contacts the tab. Slide the upper limit stop down to engage the lower limit stop. Slide the O-ring into its groove.
5. Rotate the handle counter-clockwise to the OFF position.
6. Remove the handle and install the trim.

6. Maintenance

Regular maintenance helps ensure the longevity and proper function of your mixer cap and pressure balancing unit.

• Cleaning: Periodically clean the internal components of the valve to prevent scale and debris accumulation. Buildup can lead to leaks or issues with temperature control.
• O-Ring Lubrication: If disassembling the unit for any reason, always lubricate O-rings with plumbing grease before reassembly to maintain a watertight seal and prevent premature wear.

7. Troubleshooting

7.1. Common Issues and Solutions

• Leaking Faucet:
  • Cause: Continuous accumulation of scale in the pipe, damage to gaskets, or debris within the valve.
  • Solution: Disassemble the unit, thoroughly clean the pipes and valve body. Replace any damaged O-rings or gaskets. Ensure all O-rings are properly lubricated and seated during reinstallation.
• Water Temperature Not Adjusting:
  • Cause: Internal debris, worn components, or incorrect temperature limit stop setting.
  • Solution: Clean the valve components. If the issue persists, check the temperature limiting adjustment as described in the "Operation" section. If components are significantly worn, consider replacing the mixer cap and pressure balancing unit.
