How to Test Run the Air Conditioner
After turning on the power of the air conditioner, use the
remote controller and follow the steps below to conduct the
test run.
(1) Set the remote controller in Test Run mode.
(Fig. 59a)
a) Press and hold the QUIET button and the 1HR.
TIMER button.
b) Then press and hold the ACL (Reset) button with a
pointed object such as the tip of a pen. After 5 sec-
onds, release the ACL button first.
c) Then release the QUIET and 1HR. TIMER buttons.
d) appears and “oP-1” blinks in the remote controller
clock display area. (Fig. 59b)
(2) Start Cooling mode test run by pressing the ON/OFF
operation button of the remote controller. (Fig. 59a)
• This starts the fan producing uncooled forced air with
the 3 indicator lamps (OPERATION lamp, TIMER
lamp, and LED CLEAN lamp) on the main unit
blinking. (Fig. 59c)
• After 3 minutes, the system shifts into cooling opera-
tion, and cool air will start to be felt. Cooling mode test
run is unaffected by the room temperature.
(3) Press the ON/OFF operation button of the remote con-
troller again to stop the test run. (Fig. 59a)
(4) Finally press the ACL (Reset) button of the remote con-
troller to release it from Test Run mode to return to nor-
mal mode. (Fig. 59a)
• “ ” and “oP-1” will disappear from the remote con-
troller clock display area.
Troubleshooting:
In the event that the green OPERATION lamp is blinking
upon powering up the system, an error condition exists. In
this case, refer to the self-diagnostics procedure on the
inside of the front cover.
After the test run is completed, be sure to press the ACL
(Reset) button to return to normal mode. The air conditioner
will not operate correctly if this is not done.
