9. TEST RUN

Check items
(1) Is operation of each button on the remote control unit normal?
(2) Does each lamp light normally?
(3) Do airfl ow direction louvers operate normally?
(4) Is the drain normal?
(5) Do not have an abnormal noise and vibration during operation?
Do not operate the air conditioner in test run for a long time.
[Operation method]
Depending on your installation, choose from the following:
By the wireless remote controller (with [TEST RUN] button)
• To start test run, press the [START/STOP] button and the [TEST RUN] button on the
remote controller.
• To end test run, press the remote controller [START/STOP] button.
By the indoor unit or IR receiver unit
• To start test run, press the [MANUAL AUTO] button of the unit for more than 10 seconds
(forced cooling).
• To end test run, press the [MANUAL AUTO] button for more than 3 seconds or press
the remote controller [START/STOP] button.
By the wired remote controller
• For the operation method, refer to the installation manual and the operating manual of
the wired remote controller.
The Operation indicator lamp and Timer indicator lamp will simultaneously fl ash during the

10. FINISHING

CAUTION
• After checking for gas leaks (refer to the Installation Manual of the outdoor unit),
perform this section.
• Install heat insulation around both the large (gas) and small (liquid) pipes. Failure to
do so may cause water leaks.
After checking for gas leaks, insulate by wrapping insulation around the 2 parts (gas and
liquid) of the indoor unit coupling, using the Coupler Heat Insulation.
After installing the Coupler Heat Insulation, wrap both ends with vinyl tape so that there is
no gap.
