Wiring
CAUTION
•
While connecting the wires, please strictly
follow the wiring diagram.
•
The refrigerant circuit can become very
hot. Keep the interconnection cable away
from the copper tube.
4. Clamp down the cable with the cable clamp.
The cable must not be loose or pull on the
u-lugs.
5. Reattach the electric box cover.
Using the wire controller to set external
static pressure (some models)
You can use the unit’s automatic airflow
adjustment function to set external static
pressure.
Automatic airflow adjustment is the volume
of blow-off air that has been automatically
adjusted to the quantity rated.
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 follwoing steps:
- Press“COPY”.
- Press “+” or “-” to select the AF.
- Press “CONFIRM”. The air conditioning
unit will then start the fan for airflow
automatic adjustment.
ON will flash during when the
fan is on during automatic
airflow adjustment.
After 3 to 6 minutes, the air conditioning
unit stops operating once automatic airflow
adjustment has finished.

•
CAUTION
•
DO NOT adjust the dampers when
automatic airflow adjustment is active.
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, or a HRV
via duct.
•
If the ventilation paths have been changed,
reset airflow automatic adjustment as
described from step 3 onwards.
