1. Make sure the test run is done with a dry
coil. If the coil is not dry, run the unit for 2
hours in FAN ONLY mode to dry the coil.
2. Check that both power supply wiring and
duct installation have been completed
Check that any closing dampers are open.
Check that the air filter is properly attached
to the air suction side passage of the unit.
3. If there is more than one air inlet and outlet,
adjust the dampers so that the airflow rate
of each air inlet and outlet conforms with
the designed airflow rate. Make sure the
unit is in FAN ONLY mode. Press and set
the airflow adjustment button on the
remote control to change the airflow rate
from H or L.
4. Set the parameters for automatic airflow
adjustment. When the air conditioning unit
is off, perform the following steps:

automatic airflow adjustment is active.
After 3 to 6 minutes, the air conditioning
unit stops operating once automatic airflow
adjustment has finished.
CAUTION
•
If there is no change after airflow
adjustment in the ventilation paths, be sure
to reset automatic airflow adjustment.
•
If there is no change to ventilation paths
after airflow adjustment, contact your
dealer, especially if this occurs after
testing the outdoor unit or if the unit has
been moved to a different location.
•
Do not use automatic airflow adjustment
with remote control, if you are using
booster fans, outdoor air processing unit,
