Troubleshooting.


DC, Dual Supply, Mechanical Mix

Follow the steps below to fix common problems. Before troubleshooting, remove any objects in detection zone and make sure sensor is clear of debris.

  • No Water Flow or Flow is Limited

    1. Make sure supply hoses are connected and supply stop(s) are fully open. Clean or replace filter screen gaskets or outlet insert.
    2. Check power level of unit by placing hand in detection zone for up to 20 seconds.
      1. If red sensor LED then blinks 3 times OR lights solid for 5 seconds, followed by 3 short blinks, replace batteries. Alkaline 4 “AA” recommended (lithium permitted).
      2. If red sensor LED then lights solid for 5 seconds and IS NOT followed by 3 short blinks, check that batteries are installed correctly or replace entire control box.
      3. If the red sensor LED does not appear, follow the steps below:
        1. Check internal control box power connection: battery holder is properly connected to the module (gray to gray) and solenoid is properly connected to module (black to black). If they are not, make proper connection.
        2. Use a voltmeter to ensure battery holder is providing at least 4.5 VDC power. If it is not, replace batteries, check that batteries are installed correctly or replace entire holder assembly.
        3. If battery holder is providing power, red LED should light for 5 seconds. If not, replace the spout assembly.

    Water Temperature Too Hot

    1. Check boiler temperature. Reduce as needed.
    2. Make sure cold water supply hose is connected and cold water supply stop is fully open. Clean or replace filter screen gasket.
    3. Remove control box cover. Rotate mix handle clockwise and check outlet water temperature with thermometer. Repeat until desired temperature is achieved. Reinstall cover.
    4. If above steps do not work, clean or replace mix cartridge, and check outlet water temperature with thermometer. Reinstall cover.

    Water Temperature Too Cold

    1. Check boiler temperature. Increase as needed.
    2. Make sure hot water supply hose is connected and hot water supply stop is fully open. Clean or replace filter screen gasket.
    3. Remove control box cover. Rotate mix handle counter-clockwise and check outlet water temperature with thermometer. Repeat until desired temperature is achieved. Reinstall cover.
    4. If above steps do not work, clean or replace mix cartridge, and check outlet water temperature with thermometer. Reinstall cover.
  • The Faucet is Leaking:

    From outlet – tighten or replace outlet insert using included key.
    From supply stops – install or replace filter screen gaskets.

    Water Flow Does Not Stop:

    If water flows continuously but stops when hand enters detection zone, reverse solenoid electrical connections.

    Faucet Does Not Properly Detect User:

    Remove and reapply power or run faucet to maximum run time. This will cause automatic recalibration of sensing field. Recalibration is complete when solid red light disappears.

    Customer Service:

    If the steps above do not solve the problem, you may need to replace the spout assembly or control box. For additional information contact Chicago Faucets customer service at 800/832-3783.
The mixed water temperature must be checked at the point of use and the CFC mixing valve adjusted to ensure delivery of water at a safe temperature not exceeding 110°F (43°C). Water temperatures in excess of 110°F (43°C) are dangerous and may cause scalding, severe injury, or death!
