Daikin Outdoor Heat Pump RXF71QVMA

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

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.

Caution: Restore the piping by non-oxidation brazing.

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

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

Note: Do not use a metal saw for cutting pipes by all means because the sawdust comes into the circuit.

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

Remove the electrical box cover

Disconnect the connector [S70] and release the fan motor lead wire from the slit

When reassembling, put the fan motor lead wire through the back of the fan motor to avoid any entanglement with the outdoor fan.

Remove the nut, and then the outdoor fan

When reassembling, align the mark of the fan rotor with the D-cut section of the motor shaft.

Remove the 2 screws, and then the fan motor fixing frame

When reassembling, fit the 2 lower hooks into the bottom frame.

Open the 3 hooks and release the fan motor lead wire

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

Remove the 3 screws, and then the wire fixture.

Remove the 7 screws on the terminal board and disconnect the connecting wire and power supply wire.

Disconnect the connector [S20] and pull out the clamp.

When reassembling, connect the connectors in the following order. (1) [S40] (2) [S80] (Heat Pump only) (3) [S20] (4) [S70]

Disconnect the connector [S80], pull out the clamp (1) and cut the clamp (2).

Disconnect the connector [S40].

Disconnect the relay connector for compressor and pull out the clamp.

Open the sound blanket (top) and detach the discharge pipe thermistor.

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

Remove the 6 screws, and then the top panel.

Remove the 3 screws of the terminal cover.

Unfasten the 2 hooks and remove the terminal cover.

When reassembling, make sure that the 2 hooks are securely fastened.

Pull the partition plate (2) forward, then slide to the right to remove it.

When reassembling, slide the partition plate (2) to the left to securely fasten the 2 hooks.

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.

Cautions for restoration: 1. Restore the piping by non-oxidation brazing. 2. It is required to prevent the carbonization of the oil inside the four way valve and the deterioration of the gaskets affected by heat. (Keep below 120°C (248°F).) For the sake of this, wrap the four way valve with wet cloth and provide water so that the cloth does not dry.

Note: 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.

Do not use a metal saw for cutting pipes by all means because the sawdust comes into the circuit.

When withdrawing the pipes, be careful not to pinch them firmly with pliers. The pipes may get deformed.
