•Remove the batteries from the remote controller if the sys- tem is not going to be used for a long time.

2)Precautions in test run

■The initial power supply must provide at least 90% of the rated voltage.

Otherwise, the air conditioner should not be operated.

■For test run, carry out the cooling operation firstly even during heating season. If heating operation is carried out firstly, it leads to the trouble of compres- sor. Then attention must be paid.

■Carry out the test run more than 5 minutes without fail. (Test run will be cancelled 18 minutes later auto- matically)

■The test run is started by pressing timer cancel button five times continuously. (Room type)

■To cancel the test run, press any button.
