Switch off the Daikin unit via the user interface.2. Switch off the Daikin unit with the field supplied circuit breaker.3. Remove casing when required.PROCEDURE1. Check the state of the rotor, replace the rotor if damaged, deformed, cracked or broken.2. Check the motor shaft bearing friction, only perform electrical check if motor runs with low shaft bearing friction. Replace fanmotor if friction is abnormal.PRELIMINARY ACTIONS1. Switch off the Daikin unit via the user interface.2. Switch off the Daikin unit with the field supplied circuit breaker.3. Remove casing when required.PROCEDURE1. Check fuse on indoor PCB, replace if blown.2. Check if fan motor connector is plugged into PCB.3. Power the Daikin unit.4. Check power supply, the measured voltage must be 198 - 240 VAC, if not replace indoor PCB.Technical specification DescriptionThe motor has a single connector for DC power and the rotationcounter feed back from the integrated pulse generator(4 pulses/revolution).The fan motor runs on a fixed speed to supply the required air flowrate.LocationPiping diagram Wiring diagram Switch box Component overview of unitSee "Indoor unit" onpage 104.See "Indoor unit" on page 98.
