CAUTION
Keep in mind that a shortage of airflow quantity or water leakage
will result because the air conditioner will be operated outside
the rated range of airflow quantity if the external static pressure
is wrongly set.
3. Filter sign settings
• The remote controller is provided with an LCD that tells
the time of air filter cleaning.
• If the air conditioner is used in places with excessive dust,
change the “SECOND CODE NO.” as shown in Table 5.
The “SECOND CODE NO.” is set to 01 (standard) at fac-
tory set.

* Select “No display” under conditions in which the cleaning
display is not required, such as the time of regular mainte-
nance.
12. TEST RUN
Refer to the installation manual of the outdoor unit.
• 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 corresponding trouble is pro-
vided in the installation manual attached to the outdoor unit
or the service manual.
If any of the items in Table 7 is displayed, there may be a
problem with the wiring or power supply, so check the wiring
again.

work materials, such as paint and adhesive agents, may con-
taminate the air conditioner.
