    What to do if safety series has tripped high pressure in KLH SC 2 Speakers?
    • D
      Doris PorterAug 3, 2025
      If the safety series has tripped due to high pressure in your KLH Speakers, here are some potential causes and solutions: * **Cooling water:** Check the cooling water flow and controller, as the temperature may be too high or the flow too low. * **Water temperature:** If the water temperature is too high, drain the old water and replace it with fresh water. * **Consumer input:** Reduce or turn off the consumer input if it's too high. * **Condenser:** Clean the condenser if it's dirty. * **Pressure switch:** If the pressure switch is defective, replace it and consider calling customer service. Also, every high-pressure fault must be reset at the pressure switch manually.
