8. TEST RUN
NOTE:
For information on how to check the operation of the Safety measures unit, refer to the
installation manual of the Gas sensor kit.
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
