Switch off the Daikin unit with the field supplied circuit breaker.3. Remove plate work when required (refer to "Basic removal" on page 67).4. Check the state of the propeller, replace the propeller if damaged, deformed, cracked or broken (refer to "Replacing propellerfan blade assembly" on page 93).5. Check the motor shaft bearing friction, only perform electrical check if motor runs with low shaft bearing friction. Replace fanmotor if friction is abnormal (refer to "Replacing DC fan motor assembly" on page 79).General1. Switch off the Daikin unit via the user interface.2. Switch off the Daikin unit with the field supplied circuit breaker.3. Remove plate work when required (refer to "Basic removal" on page 67).4. Check fuse on PCB, replace if blown.5. Check if fan motor connector is plugged into PCB.6. Power the Daikin unit.7. Check power supply, the measured voltage must be 198 - 240 VAC, if not replace main PCB (refer to "Replacing main PCB"on page 89).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 "Outdoor unit" onpage 117.See "Outdoor unit" onpage 115.See "Outdoor unit" onpage 122.See "Outdoor unit" on page 119.Check procedureMechanical checkElectrical checkWARNING: R ISK OF F IREWhen reconnecting a connector to the PCB, do not apply force, as this may damage the connector or connector pins ofthe PCB.
