3.4. Preparing the indoor unit
* Check beforehand because the preparatory work will differ depending on the
exiting direction of the piping.
* When bending the piping, bend gradually while maintaining the base of the
piping exiting portion. (Abrupt bending will cause misshaping of the piping.)
* Do not perform piping on the right side.

1. Attach the charge nut 5to the liquid pipe side joint portion.
Tightening force: 34~42 N•m, 25~30ft lbs
2. Pressurize by filling with nitrogen gas from the charge nut.
Do not pressurize to the current constant pressure all at once. Pressurize
gradually.
1) Pressurize to 0.5 MPa, 73PSIG wait five minutes, and make sure the
pressure does not decrease.
2) Pressurize to 1.5 MPa, 218PSIG wait five minutes, and make sure the
pressure does not decrease.
3) Pressurize to 4.15 MPa, 601PSIG and measure the surrounding temperature
and refrigerant pressure.
3. If the specified pressure holds for about one day and does not decrease, the
pipes have passed the test and there are no leaks.
• If the surrounding temperature changes by 33.8°F, the pressure will change by
about 0.01 MPa, 1.5PSIG. Make the necessary corrections.
4. If the pressure decreases in steps (2) or (3), there is a gas leak. Look for the
source of the gas leak.

■ 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 3 minutes.
● Indoor controller board: LED 1 will be lit up, LED 2 will be lit up (if the address is 0) or off (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 finishes, LED 2 will be turned off.) 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.)

Step4 Conrmtheoperationoftheoutdoorunitfan.
The speed of the outdoor unit fan is controlled in order to control the performance of the unit. Depending on the ambient air, the fan will rotate at a slow speed and will keep
rotating at that speed unless the performance is insu cient. Therefore, the outdoor wind may cause the fan to stop rotating or to rotate in the opposite direction, but this is
not a problem.
