10TEST RUN

„Before test run

Confirm that the valve of the refrigerate pipe of the outdoor unit is OPEN.

•Before turning on the power, confirm that the resistance between the terminal block of power supply and the earth is more than 1MΩ using a 500V megohmmeter.

Do not run the unit if it is less than 1MΩ.

CAUTION

•Turn on the power and turn on the case heater of the compressor.

To save the compressor when it is activated, leave the power on for more than 12 hours.

„Methods of test run

◆When executing a test run using a

remote controller

Operate the system normally to check the running condition using the wired remote controller. Follow the instructions in the supplied owner’s manual when operating the unit.

If you use a wireless remote controller for operations, follow the instructions in the installation manual supplied with the indoor unit.

To execute a test run forcibly under the condition that the thermostat automatically turns the unit off due to the indoor temperature, follow the procedure below.

The forcible test run will automatically stop after 60 minutes to prevent continuous forcible running and return to normal running.

CAUTION

Do not use forcible running except for a test run as it overloads the unit.

◆When executing a test run using the interface P.C. board on the

outdoor unit

You can execute a test run by operating switches on the interface P.C. board of the header outdoor unit.

“Individual trial”, which tests each indoor unit separately, and “corrective trial”, which tests all the indoor units connected, are available.

<Individual test operation>

▼Starting operation

1 Set the running mode to “COOL” or “HEAT” on the remote controller of the indoor unit to be tested.

(The unit will run in the current mode unless you set the mode otherwise.)
