Troubleshooting.


SSPS, Dual Supply, Thermostatic 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 entire control box.
      2. If red sensor LED then lights solid for 5 seconds and IS NOT followed by 3 short blinks, replace entire control box.
      3. If the red sensor LED does not appear, follow the steps below:
        1. Check internal control box power connection: SSPS power supply is properly connected to the module (gray to gray), solenoid is properly connected to module (black to black) and turbine is properly connected to SSPS power supply (blue to blue). If they are not, make proper connection.
        2. Use a voltmeter to ensure SSPS power supply is providing at least 4.5 VDC power. If it is not, replace SSPS power supply or entire control box assembly.
        3. If SSPS power supply is providing power, red LED should light for 5 seconds. If not, replace the spout assembly.

    Water Temperature Too Hot

    1. Check outlet water temperature with thermometer. If temperature exceeds 120° F, remove control box cover, then clean or replace thermostatic cartridge.
    2. Rotate mix handle counter-clockwise to full hot position and check outlet water temperature with thermometer.
    3. If temperature will still not drop below 120° F, replace cartridge, then set desired outlet temperature. Reinstall cover.
    4. Check outlet water temperature with thermometer. If temperature does not exceed 120° F, but is still too hot, check boiler temperature. Reduce as needed.
    5. Make sure cold water supply hose is connected and cold water supply stop is fully open. Clean or replace filter screen gasket.
    6. Remove control box cover. Rotate mix handle clockwise and check outlet water temperature with thermometer. Repeat until desired temperature is achieved. 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!

Periodic inspection and yearly maintenance by a licensed contractor is required for all thermostatic mixing elements. Corrosive water conditions and/or unauthorized adjustments or repair could render the thermostatic valve ineffective for service intended.
