Note:
1. “Mode No.” setting is done in a batch for the group. To make or confirm settings for an individual unit, set
the internal mode number in parentheses.
2. Make settings for “No Display” in cases where no cleaning display is required, e.g., at the time of regular
maintenance servicing.
• The air conditioner is provided with a long life filter as a standard accessory. Explain to the customer the
necessity of cleaning the filter periodically along with the set time for filter cleaning for the prevention of
clogging.
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 provided in the installation manual attached to the outdoor unit or the service
manual.
If any of the items in “Table 6” is displayed, there may be a problem with the wiring or power supply, so check
the wiring again.

indoor unit, and they may cause splashing or leakage of water.)
