In case of 4-way Cassette type, test run operation is not possible without the ceiling panel installation.

To protect the air conditioner from overloading, the outdoor unit will not start running for 3 minutes after power is applied or the air conditioner is turned off and then back on.

When the air conditioner fails to start the test run, 1 or more of the 3 alarm indicator lamps on the indoor unit will flash (See next section).

When the DIP switch is set to “TEST – ON,” temperature control from the wireless remote controller is disabled. Do not use this setting at any time other than for the test run. Doing so will place an excessive load on the system.

To avoid placing an excessive load on the equipment, use this function only when conducting the test run.
