• The check run is a function to screen and detect any wiring errors.
• After carrying out the check run, you can use the automatic wiring correction function to correct the
wiring.
• Normal operation is possible without using the check run. In this case, use the test run or forced
cooling function of the indoor unit to confirm any wiring errors.

Restrictions applicable when performing the check run
• When the check run starts, all indoor units connected to the outdoor unit will start to run automati-
cally. During the check run, you cannot check the operation of the indoor units separately. After
the check run, check the operation of the indoor units separately in normal operation.
• The check run can be used when the temperature is within the operable temperature of the air
conditioner.
• In the check run, the air conditioner will automatically switch between cooling and heating depend-
ing on the external temperature and internal temperature.
• The check run can be completed in about 30 minutes (cooling) or about 1 hour (heating), but may
take more depending on the external and internal temperature conditions etc.
• Do not conduct the check run with all the windows in the room closed.
Otherwise the room temperature could get too low or too high.
• Depending on the difference of the room temperature of each room, a judgment may be impossi-
ble.
• Check run is a special operation so there may be a noise louder than the normal refrigerant flow
sound or a creaking noise.
