7. FINISHING
(1) Insulate between pipes.
• Overlap the connection pipe heat insulation and indoor unit pipe heat insulation.
• Wrapping the connection pipe with cloth tape over the range within which they fit into
the rear piping housing section.
• Fasten the pipe bracket with the screw.
(2) Fill the gap between the outside wall pipe hole and the pipe with sealer so that rain
water and wind cannot blow in.
(3) Fasten the drain hose to the outside wall, etc.

8. CUSTOMER GUIDANCE
Explain the following to the customer in accordance with the operation manual:
(1) Starting and stopping method, operation switching, temperature adjustment, timer,
airflow switching, and other remote controller operations.
(2) Air filter removal and cleaning, and how to use the air louvers.
(3) Give the operation manual to the customer.
9. 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. Refer to the lamp blinking patterns and error codes in
the table. An error display is displayed only during operation.
The error code table contains errors irrelevant to this product as well.
