paying attention to the room temperature.
• After 60 minutes, the test run will be completed to protect the equipment, and the normal operation
will be started according to the set temperature.
However, if there is no remote controller (using a central controller), please manually stop the test
run after 60 minutes because there are some type of indoor unit that will continue operating test run
even after 60 minutes.
Be sure to turn on power at the indoor side
