(a)Outline of Judgment

A primary judgment to detect cause of error exists on the indoor unit or outdoor unit is performed in the following procedure.

<Judgment by flashing display on the indoor unit display part>

The indoor unit monitors operating status of the air conditioner, and if a protective circuit works, contents of the self-diagnosis are displayed with a block restricted to the following cases on the indoor unit display part.

<Wireless remote controller type>

1. Before troubleshooting

1) Required tools/instruments

• + and – screwdrivers, spanners, radio cutting pliers, nippers, etc.

•Tester, thermometer, pressure gauge, etc.

2)Confirmation points before check

•The following operations are normal.

a)Compressor does not operate.

•Is not 3-minutes delay (3 minutes after compressor OFF)?

•Does not thermostat turn off?

•Does not timer operate during fan operation?

•Is not outside high-temperature operation controlled in heating operation?

b)Indoor fan does not rotate.

•Does not cool air discharge preventive control work in heating operation?

c)Outdoor fan does not rotate or air volume changes.

•Does not high-temperature release operation control work in heating operation?

•Does not outside low-temperature operation control work in cooling operation?

•Is not defrost operation performed?

d)ON/OFF operation cannot be performed from remote controller.

•Is not forced operation performed?

•Is not the control operation performed from outside/remote side?

‚Did you return the cabling to the initial positions?

ƒAre connecting cables between indoor unit and receiving unit correct?
