Daikin Cooling-Only Outdoor Unit RKS60E2V1B

Warning: This check requires trained personnel with PPE!

Enter the power supply waveform measurement between No.1 and No.2 on the terminal board

Upload a photo of the measured waveform

Is the power supply waveform a sine wave?

Is there waveform disturbance near the zero cross?

Sign off on the power supply waveform check

Voltage of 320 ± 30 V is applied

Set operation off and power off. Disconnect the connector S70

Control voltage between the pins 3 - 4

Rotation command voltage between the pins 2 - 4

Keep operation off and power off. Connect the connector S70

2 pulses (0 ~ 15 VDC) are output at the pins 1 - 4 when the fan motor is rotated 1 turn by hand

Warning: Disconnect the connectors of the thermistors from the PCB before proceeding

Thermistors disconnected from the PCB?

Measure the resistance of each thermistor

Select the model of the thermistor

Upload a photo of the tester reading

Sign off on the thermistor resistance check

Warning: Ensure that the voltage between (+) and (–) of the diode bridge (DB1) is approx. 0 V before proceeding

Voltage between (+) and (–) of the diode bridge (DB1) is approx. 0 V

Disconnect the compressor harness connector from the outdoor unit PCB. To disengage the connector, press the protrusion on the connector.

Compressor harness connector successfully disconnected

Measure resistance between the terminals of the DB1 and the terminals of the compressor with a multi-tester.

Warning: Be sure to wait for 10 minutes or more after turning off all power supplies before disassembling work.

Remove the 4 screws and lift the top panel. Take care not to cut your finger by the fins of the outdoor heat exchanger.

Remove the 4 screws and remove the discharge grille. Slide the discharge grille upwards and remove it. The discharge grille has 4 hooks.

Remove the 6 screws of the front panel.

Push the front panel and lift the shield plate to unfasten the hooks.

Unfasten the left side hooks, and then the right side hook.

Lift the front panel while pushing the left side panel inwards.

Lift the front panel and unfasten the right side hook.

When reassembling, fit the right side of the front panel first.
