Customer Guidance; Error Codes - Fujitsu ASYG36LMTA Installation Manual

15. CUSTOMER GUIDANCE

Explain the following to the customer in accordance with the operating manual:
(1) S tarting and stopping method, operation switching, temperature adjustment, timer, air
flow switching, and other remote control unit operations.
(2) A ir filter removal and cleaning, and how to use the air louvers.
(3) Give the operating manual to the customer.

16. 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 ap-
pear on the remote control display. See the lamp blinking patterns and error codes in the
table. An error display is displayed only during operation.
