9. TEST RUN

9. 1. Check items
□
Is operation of each button on the remote control unit normal?
□
Does each lamp light normally?
□
Is the drain normal?
□
Do not have an abnormal noise and vibration during operation?
Do not operate the air conditioner in test run for a long time.

9. 2. 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 IR receiver unit
• To start test run, press the [MANUAL AUTO] button of the IR receiver 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.
• The Operation indicator lamp and Timer indicator lamp will simultaneously fl ash during
the test run mode.
■ By the wired remote controller
• For the operation method, refer to the installation manual and the operating manual of
the wired remote controller.
Heating test run will begin in a few minutes when HEAT is selected by the remote controller
[reverse cycle model only].

10. FINISHING

Install the heat insulation material after performing a refrigerant leak check (see the
installation manual for the outdoor unit for details).

CAUTION
There should be no gaps between the insulation and the product.
CAUTION
• After connecting the piping, check the all joints for gas leakage with gas leak detector.
• Once the pressure checking has been completed using nitrogen, please refer to the
outdoor unit installation manual to complete the evacuation process.
• Install heat insulation around both the large (gas) and small (liquid) pipes. Failure to
do so may cause water leaks.

11. CUSTOMER GUIDANCE

Explain the following to the customer in accordance with the operating manual:
(1) Starting and stopping method, operation switching, temperature adjustment, timer, and
other remote controller operations.
(2) Cleaning and maintenance of the product, and other items such as air fi lters and air
louvers if applicable.
(3) Give the operating and installation manuals to the customer.
(4) If the indoor unit custom code is changed, and the installation includes a wireless
remote controller, inform the customer the changed code. (On some wireless remote
controllers, the custom code may return to A when batteries are replaced.)
