Installation Steps
- Prepare the Rough-in Valve: Ensure the rough-in valve (sold separately) is securely installed in the wall according to its specific instructions and local plumbing codes.
- Connect Water Supplies: Connect the hot and cold water supply lines to the appropriate inlets on the rough-in valve. Ensure all connections are watertight.
- Install Thermostat Cartridge: Insert the thermostatic cartridge into the rough-in valve body. Align any keys or notches as specified by the rough-in valve manufacturer. Secure the cartridge with the retaining nut or clip.
- Install Escutcheon Plate: Position the escutcheon plate over the rough-in valve and secure it to the wall using the provided screws. Ensure it is flush and level.
- Install Handle Assembly: Attach the handle assembly to the cartridge stem. Secure it with the set screw, typically located on the underside of the handle.
- Test for Leaks: Slowly turn on the main water supply and check all connections for leaks.
- Calibrate Temperature (if necessary): Refer to the rough-in valve's instructions for initial temperature calibration or adjustment of the high-temperature limit stop.
Operating Instructions
The Phylrich Amphora Thermostat provides precise control over water temperature.
Temperature Control
- Turning On/Off: Rotate the handle to the desired position to turn on the water flow. Rotate back to the off position to stop the flow.
- Adjusting Temperature: Rotate the handle to adjust the water temperature. Turning the handle counter-clockwise typically increases the temperature, while clockwise rotation decreases it.
- High Temperature Limit Stop: Your thermostat is equipped with a high-temperature limit stop for safety. To adjust this limit, consult the rough-in valve's specific instructions. This feature prevents accidental scalding.
Always test the water temperature with your hand before stepping into the shower or bath.
Maintenance and Care
Proper care will ensure the longevity and appearance of your Phylrich Amphora Thermostat.
- Cleaning: Clean the thermostat's surface with a soft, damp cloth. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Cartridge Maintenance: If water flow or temperature control becomes erratic, the thermostatic cartridge may require cleaning or replacement. This should be performed by a qualified plumber.
- Hard Water Areas: In areas with hard water, mineral deposits may accumulate. Regular cleaning can prevent buildup. For stubborn deposits, a solution of white vinegar and water (50/50) can be used, applied with a soft cloth and rinsed thoroughly.
