    What to do if my Phcbi Laboratory Equipment chamber does not get cold enough?
    • J
      Jason NashSep 2, 2025
      If the chamber isn't getting cold enough, consider these possible causes: * Reduce the amount of items stored inside or allow warm items to cool before placing them in the chamber. * Limit how often the door is opened. * Lower the chamber temperature setting. Also, relocate the unit away from direct sunlight and ensure it's installed according to the operating instructions, with no blocked ventilation or nearby heat sources. Verify that the ambient temperature is within the allowable range (between 5 oC and 30 oC). Cover the access port when not in use, and remove any foreign substances between the door gaskets. If the door seal is damaged, contact a sales representative or agent for replacement.

    What to do if the alarm device is activated during operation of my Phcbi Laboratory Equipment?
    • J
      John GonzalesAug 31, 2025
      If the alarm activates during operation, several factors could be the cause. First, check the power supply connection and ensure it meets the required specifications. Also, verify there isn't a power outage or a tripped circuit breaker, and that the fuse isn't blown. If power isn't the issue, check the chamber temperature setting and make sure the door isn't open or hasn't been opened for an extended period. Remove any containers with high temperatures from the chamber. Finally, ensure the door is properly closed.

    Why is my Phcbi Freezer making excessive noise?
    • L
      Lisa FieldsAug 27, 2025
      Excessive noise can be attributed to a few reasons: the floor may not be stable, the installation site might not be level, or the freezer could be tilted. Also, check if the cabinet is touching the surrounding wall.

    • M
      Matthew SullivanAug 25, 2025
      If your unit isn't operating, verify that it's properly connected to the power supply. Also, check that the power supply's capacity and voltage are adequate. A power failure, a tripped circuit breaker on the supply circuit, or a blown fuse could also be the cause.

    Why is my Phcbi Freezer not cold enough?
    • T
      Terry MckinneyAug 23, 2025
      Several factors can impact the cooling performance of your freezer. Avoid placing warm materials inside and minimize how often you open the door. Ensure the temperature setting isn't too high. Direct sunlight, improper installation, blocked ventilation, or nearby heat sources can also affect cooling. The ambient temperature should be between 5°C and 30°C. Avoid overfilling the chamber and ensure the access port is covered with insulation and rubber caps when not in use. A damaged door seal or foreign substances between the door gaskets may also be the cause. If the door seal is damaged, contact our sales representative or agent for replacement.
