Test Run; Check Items; Operation Method; Finishing - Fujitsu ARXG-KLLAP Series Installation Manual

7. TEST RUN

7.1. Check items

□ Is operation of each button on the remote controller 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.

7.2. Operation method

Depending on your installation, choose from the following:
■ By the wireless remote controller (with [TEST RUN] button)
(1) To start test run, press [START/STOP] and [TEST RUN] on the remote controller.
(2) To end test run, press [START/STOP] on the remote controller.
■ By the indoor unit or IR receiver unit
(1) To start test run, press [MANUAL AUTO] of the unit for more than 10 seconds (forced
cooling).
(2) To end test run, press [MANUAL AUTO] for more than 3 seconds or press [START/STOP]
on the remote controller.
 The Operation indicator lamp and Timer indicator lamp will simultaneously fl ash during
the test run mode.
■ By the wired remote controller
(1) 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 control-
ler [reverse cycle model only].

8. FINISHING

Install the heat insulation material after performing a refrigerant leak check (Refer to the
Installation manual for the outdoor unit for details).
■ Coupler heat insulation
• 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.
• Insulate with the coupler heat insulation (accessories) around the gas pipe and liquid
pipe at indoor unit.
• After installing the coupler heat insulation, wrap both ends with vinyl tape so that
there is no gap.
• After affi xing the coupler heat insulation, secure it with 2 cable tie (large,
accessories), one on each end of the insulation.
• Make sure that the cable tie overlap the heat insulation pipe.

9. CUSTOMER GUIDANCE

Explain the following to the customer in accordance with the operating manual:
(1) Starting and stopping method, operation switching, temperature adjustment, timer, air
fl ow switching, 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.)
CAUTION
Cover this portion with
heat insulation.

10. ERROR CODES

If you use a wireless remote controller, the lamp on the photo detector unit will output error
codes by way of blinking patterns. If you use a wired remote controller, error codes will ap-
pear on the remote control display. Refer to the lamp blinking patterns and error codes in
the table. An error display is displayed only during operation.
