    Capacitors

    The drive intermediate circuit employs several electrolytic capacitors. Their life span is from 35,000…90,000 hours depending on drive loading and ambient temperature. Capacitor life can be prolonged by lowering the ambient temperature.

    It is not possible to predict a capacitor failure. Capacitor failure is usually followed by a input power fuse failure or a fault trip. Contact Daikin if capacitor failure is suspected. Replacements for frame size R5 and R6 are available from Daikin. Do not use other than Daikin specified spare parts.

    Control Panel

    Cleaning

    Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch the display window.

    Battery

    A battery is only used in Assistant control panels that have the clock function available and enabled. The battery keeps the clock operating in memory during power interruptions.

    The expected life for the battery is greater than ten years. To remove the battery, use a coin to rotate the battery holder on the back of the control panel. Replace the battery with type CR2032.

    NOTE: The battery is NOT required for any control panel or drive function, except the clock.
