Process of Oil Charging Step by Step (2) Purge 2 points like pictures. (3) Open VA1 and then Vacuum Oil charger. You have to vacuum at least 1 min. VA1

Process of Oil Charging Step by Step (4) Open VA2. You have to vacuum continuously. And Put the Oil into Oil charger like picture. At this time, you have to vacuum putting oil, so you can put oil easily. VA2

Process of Oil Charging Step by Step (5) Close VA2. You have to vacuum at least 10 min more. VA2 (6) Close VA1 and then Turn Vacuum pump off. VA1

Process of Oil Charging Step by Step (7) Turn Unit on with Test mode (cooling/Heating) ■ DVM PLUS 2 : Press button 2 times K1 K2 Cooling Mode Heating Mode ■ DVM PLUS 3 : Press button 2 times K2 K1 Cooling Mode Heating Mode

Process of Oil Charging Step by Step (8) Open VA3 after 10 min, and then Open VA4. VA3 VA4 (9) Check charging oil through the Sight glass. When you see bubble through the Sight glass, then Close VA3 and then Close VA4 after at least 1 min

Process of Oil Charging Step by Step (10) Turn Unit off after 5 min. DVM PLUS 2 DVM PLUS 3 (11) Remove remain oil inside Oil charger like picture.
