9-13. When Removing the Ceiling Panel for Servicing
When removing the ceiling panel for servicing, remove the air-
intake grille and air filter, disconnect the wiring connector inside
the electrical component box, and then remove the 4 mounting
screws.
9-14. Adjusting the Auto Flap
The air-direction louver on the ceiling panel outlet can be
adjusted as follows.
● Adjust the louver to the desired angle using the remote
controller. The louver also has an automatic air-sweeping
mechanism.

● Never attempt to move the louver by hand.
● Proper airflow depends on the location of the air conditioner,
the layout of the room and furniture, etc. If cooling or heating
seems inadequate, try changing the direction of the airflow.
10. TEST RUN

10-1. Preparing for Test Run

● Before attempting to start the air conditioner, check the
following:
(1) All loose matter is removed from the cabinet especially
steel filings, bits of wire, and clips.
(2) The control wiring is correctly connected and all electrical
connections are tight.
(3) The protective spacers for the compressor used for
transportation have been removed. If not, remove them
now.
(4) The transportation pads for the indoor fan have been
removed. If not, remove them now.
(5) The power has been supplied to the unit for at least 5
hours before starting the compressor. The bottom of
the compressor should be warm to the touch and the
crankcase heater around the feet of the compressor should
be hot to the touch.

10-2. Caution
●
This unit may be used in a single-type refrigerant
system where 1 outdoor unit is connected to 1 indoor
unit, and also in a system where 1 outdoor unit is
connected to multiple indoor units (maximum 4).
* If multiple indoor units are used, also refer to "10-8. System
Control."
●
The indoor and outdoor unit control PCB utilizes
a semiconductor memory element (EEPROM). The
settings required for operation were made at the time of
shipment.
Only the correct combinations of indoor and outdoor
units can be used.
●
This test run section describes primarily the procedure
when using the wired remote controller.
