8. TEST RUN
8.1. Test run using Outdoor unit (PCB)
• Refer to the Installation Manual for the outdoor unit if the PCB for the outdoor unit is to
be used for the test run.
8.2. Test run using Remote Controller
• Refer to the Installation Manual for the remote controller to perform the test run using
the wireless remote controller.
• When the air conditioner is being test run, the OPERATION and TIMER indicator lamps
fl
ash slowly at the same time.
For details, please refer to the Manual of “IR Receiver Unit” or “Wired Remote Controller”.
