Daikin Cooling-Only Outdoor Unit RKS60F2V1B

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

Disconnect the lead wires of the compressor.

Release the clamp with pliers to detach the compressor lead wires.

Warning: Be careful not to get yourself burnt with the pipes and other parts that are heated by the gas brazing machine.

Warning: If the refrigerant gas leaks during work, ventilate the room. (If the refrigerant gas is exposed to flames, toxic gas may be generated.)

Warning: Since it may happen that the refrigerant oil in the compressor catches fire, prepare wet cloth so as to extinguish fire immediately.

Caution: From the viewpoint of global environment protection, do not discharge the refrigerant gas in the atmosphere. Make sure to collect all the refrigerant gas.

EV connector correctly connected to the PCB

EV generates latching sound when power is turned off and on again

Continuity present when connector is disconnected and checked with a tester

Continuity between the pins 1 - 6 and 3 - 6

Continuity between the pins 2 - 5 and 4 - 5

If there is no continuity between the pins, the EV coil is faulty

If the continuity is confirmed, the outdoor unit PCB is faulty

Note: The latching sound varies depending on the valve type

Sign off on the electronic expansion valve check

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

Remove the sound blanket (back)

Remove the sound blanket (outer)

Since the piping ports are torn easily, remove the sound blanket carefully.

Remove the sound blanket (top upper)

Remove the sound blanket (top lower)

Remove the sound blanket (inner)

Release the discharge pipe thermistor

Be careful not to lose the clip for the thermistor.

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

Pull out the electronic expansion valve coil.

Warning: Be careful not to get yourself burnt with the pipes and other parts that are heated by the gas brazing machine.

Warning: If the refrigerant gas leaks during work, ventilate the room. (If the refrigerant gas is exposed to flames, toxic gas may be generated.)

Caution: From the viewpoint of global environment protection, do not discharge the refrigerant gas in the atmosphere. Make sure to collect all the refrigerant gas.

Before working, make sure that the refrigerant gas is empty in the circuit.

Be sure to apply nitrogen replacement when heating up the brazed part.

Heat up the 2 brazed parts of the electronic expansion valve and remove it.
