13. CUSTOMER GUIDANCE
Explain the following to the customer in accordance with the operating manual:
(1) Starting and stopping method, operation switching, temperature adjustment, timer, air
fl
ow switching, and other remote controller operations.
(2) Air
fi
lter removal and cleaning, and how to use the air louvers.
(3) Give the operating manual to the customer.
14. ERROR CODES
If you use a wireless remote controller, the lamp on the photo detector unit will output
error codes by way of blinking patterns. If you use a wired remote controller, error codes
will appear on the remote control display. See the lamp blinking patterns and error codes
in the table. An error display is displayed only during operation.
