Troubleshooting Insufficient Hot Water from Artos F904A-VO Valve
If you're experiencing lukewarm water from your Artos F904A-VO valve, consider these potential causes:
Incoming Hot Water Temperature
Verify that the incoming hot water temperature is at least 50°F higher than your desired mixed temperature. It's recommended to have a minimum of 170°F (maximum 185°F).
Calibration
Remove the handle and turn the spindle counterclockwise as much as possible. Reattach the handle with the anti-scald button at the 9 o'clock position. Press the anti-scald button while placing it on the spindle.
Pressure/Flow Imbalance
An imbalance between cold and hot water pressure can affect the mixed temperature. Close the cold side service stops partially by turning them clockwise to achieve a balanced pressure and flow.
Additionally, if certain functions provide the desired temperature while others don't, it's possible that a function is plumbed to the bottom of the valve which is warned against in the installation manual. Refer to Step 1 to verify the reccomended plumbing.
Addressing these factors can help ensure consistent and satisfying hot water from your Artos F904A-VO valve.
