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 specied 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.
