4.2. Connectingpipes(Fig.4-1)
• When commercially available copper pipes are used, wrap liquid and gas pipes
with commercially available insulation materials (heat-resistant to 100 °C or more,
thickness of 12 mm or more).
• The indoor parts of the drain pipe should be wrapped with polyethylene foam insula-
tion materials (specic gravity of 0.03, thickness of 9 mm or more).
• Apply thin layer of refrigerant oil to pipe and joint seating surface before tightening
are nut.
• Use 2 wrenches to tighten piping connections.
• Use refrigerant piping insulation provided to insulate indoor unit connections. Insulate
carefully.
• After connecting the refrigerant piping to the indoor unit, be sure to test the pipe
connections for gas leakage with nitrogen gas. (Check that there is no refrigerant
leakage from the refrigerant piping to the indoor unit.)
• Use ared nut installed to this indoor unit.
• In case of reconnecting the refrigerant pipes after detaching, make the ared part
of pipe re-fabricated.

7.2.1. Usingwiredremotecontroller.
■ Make sure to read operation manual before test run. (Especially items to secure safety)
Step 1 Turn on the power.
● Remote controller: The system will go into startup mode, and the remote controller power lamp (green) and “Please Wait” will blink. While the lamp and message are
blinking, the remote controller cannot be operated. Wait until “Please Wait” is not displayed before operating the remote controller. After the power is turned on, “Please
Wait” will be displayed for approximately 2 minutes.
● Indoor controller board: LED 1 will be lit up, LED 2 will be lit up (if the address is 0) or o󰀨 (if the address is not 0), and LED 3 will blink.
● Outdoor controller board: LED 1 (green) and LED 2 (red) will be lit up. (After the startup mode of the system nishes, LED 2 will be turned o󰀨.) If the outdoor controller
board uses a digital display, [- ] and [ -] will be displayed alternately every second.
If the operations do not function correctly after the procedures in step 2 and thereafter are performed, the following causes should be considered and eliminated if they
are found.
(The symptoms below occur during the test run mode. “Startup” in the table means the LED display written above.)
