Refrigerant Shortage Check

Warning: This check requires trained personnel with PPE!

Enter the superheating degree of suction gas

Has the compressor discharge gas temperature become higher?

Has the electronic expansion valve turned open?

Has the low pressure dropped causing the unit not to demonstrate cooling/heating capacity?

Sign off on the refrigerant shortage check

Run this procedure

Refrigerant Overcharge Check

Warning: This check requires trained personnel with PPE!

Enter the high pressure reading

Is overload control conducted causing insufficient cooling capacity?

Enter the superheating degree of suction gas

Is the compressor lower in discharge pipe temperature despite of pressure loads?

Enter the subcooling degree of condensate

In heating, is the temperature of discharge air through the subcooled section lower?

Sign off on the refrigerant overcharge check

Run this procedure

Broken Wire Check

Warning: Ensure the power supply to all equipment is turned OFF before starting the procedure.

Power supply to all equipment turned OFF?

Short circuit between the indoor-outdoor unit terminal F1 and F2 in the outdoor unit.

Short circuit between the indoor-outdoor unit terminal F1 and F2 in the outdoor unit done?

Conduct continuity checks between the transmission wirings F1 and F2 of the indoor unit a that is farthest from the outdoor unit using a multimeter.

Continuity check done?

Is there continuity between the said transmission wirings?

If there is no continuity, the transmission wiring may have broken wires. With the indoor-outdoor unit terminal of the outdoor unit short circuited, identify the place with continuity in the transmission wiring of the indoor unit b, transmission wiring of the indoor unit c, and transmission wiring of the indoor unit d in the order described.

Identify the place with continuity in the transmission wiring of the indoor unit b, transmission wiring of the indoor unit c, and transmission wiring of the indoor unit d.

Run this procedure

Power Transistor Check

Warning: Power OFF before starting the procedure

Remove all the wiring connected to the PCB where power transistors are mounted on

Prepare a multimeter. An analog system is recommended, but a digital system with diode check function is also usable

Wait for 10 minutes after power OFF before starting the measurement

Choose the type of multimeter used

Measurement in the resistance value mode in the range of multiplying 1 kΩ (for analog multimeter)

Measurement in the diode check mode (for digital multimeter)

Sign off on the power transistor check
