FAQ


  • What should I do if the heat pump unit fails to start after being powered on?
    Created with Sketch.
    形状 Created with Sketch.
    Please check the power switch, wiring connections, and fuses in sequence to ensure they are functioning correctly. If the compressor fails to start, you should also verify whether the water outlet temperature setting is set too high, which could trigger the overheat protection mechanism.
  • How should I address a "Water Flow Protection" fault reported by the system?
    Created with Sketch.
    形状 Created with Sketch.
    First, check to ensure the water circulation system is unobstructed and that all valves are fully open. Next, inspect the water flow switch to see if it is damaged. If necessary, you may bypass (short-circuit) the water flow switch temporarily to help isolate the source of the fault.
  • What causes insufficient heating capacity during winter operation?
    Created with Sketch.
    形状 Created with Sketch.
    This may be due to frost accumulation on the outdoor finned heat exchanger, which reduces heat exchange efficiency, or a shortage of refrigerant within the system. It is recommended to first verify that the defrosting function is operating correctly; if necessary, contact a professional technician to check the refrigerant levels.
  • What should I do if the noise level of the heat pump unit increases abnormally during operation?
    Created with Sketch.
    形状 Created with Sketch.
    First, check to ensure there is a sufficient amount of water in the storage tank. If the water level is normal, you can bleed any trapped air from the water pump using the unit's air vent. If the issue persists, it is recommended to contact after-sales support personnel for further diagnostics.
  • How can I reduce the daily operating and maintenance costs of the heat pump unit?
    Created with Sketch.
    形状 Created with Sketch.
    It is recommended to regularly clean the water filter, inspect the system for any potential leaks, and ensure that the area surrounding the outdoor unit remains well-ventilated. Setting the water outlet temperature appropriately—avoiding excessively high settings—can significantly improve energy efficiency and reduce operational energy consumption.
