11. FIELD SETTING AND TEST RUN
Field settings may have to be performed using the

(1) Make sure the control box lids are closed on the indoor
and outdoor units.
(2) Depending on the type of installation, make the field
settings from the remote controller after the power is
turned on, following the “Field Settings” manual which
came with the remote controller.
•
The settings can select “Mode No.”, “FIRST CODE NO.”
and “SECOND CODE NO.”.
•
The “Field Settings” included with the remote controller
lists the order of the settings and method of operation.
•
Lastly, make sure the customer keeps the “Field Settings”
manual, along with the operating manual, in a safe place.

ual included with the wireless remote controller for details on
how to make the settings.
(3) Perform a test run according to the outdoor unit’s
installation manual.

The operation lamp of the remote controller will flash
when a malfunction occurs. Check the malfunction code
on the liquid crystal display to identify the point of trouble.
An explanation of malfunction codes and the correspond-
ing trouble is provided in “CAUTION FOR SERVICING”
of the outdoor unit.
If the display shows any of the following, there is a possi-
bility that the wiring was done incorrectly or that the
power is not on, so check again.

Always stop the test run using the remote controller to stop
operation.
