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.
