Page 67: Vacuum Dry And Leakage Checking
Test Operation 2. Vacuum Dry and Leakage Checking Vacuum Dry: use vacuum pump to change the moisture (liquid) into steam (gas) in the pipe and discharge it out of the pipe to make the pipe dry. Under one atmospheric pressure, the boiling point of water(steam temperature) is 100 . Use vacuum pump to make the ℃... - Page 68 Water Drainage ②. Special vacuum dry procedure This vacuum dry method is used in the following conditions: There’s moisture when flushing the refrigerant pipe. Rainwater may enter into the pipe. Vacuum dry for the first time ······ 2h pumping ③. Vacuum destroy for the second time ······ Fill nitrogen to 0.5Kgf/cm Because nitrogen is for drying gas, it has vacuum drying effect during vacuum destroy.

Page 69: Additional Refrigerant Charge
Test Operation Additional Refrigerant Charge Caution: Refrigerant cannot be charged until field wiring has been completed. Refrigerant may only be charged after performing the leak test and the vacuum pumping. When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in view of the danger of liquid hammer. -
Page 70: Water Drainage
Water Drainage Water Drainage 4.1 Gradient and Supporting 1). Keep the drainpipe sloping downwards at a gradient of at least 1/50. Keep the drainpipe as short as possible and eliminate the air bubble. 2). The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to keep the gradient of 1/50 and prevent bending. -
Page 71: Drainage Test
Test Operation For Four-way cassette 4.4 Convergent drainage 1). The number of indoor units should be as small as possible to prevent the traverse main pipe overlong. 2). Indoor unit with drain pump and indoor unit without drain pump should be in different drainage system. 3). - Page 72 Water Drainage ③ Stop the air conditioner running, turn off the power, and put back the cover. Stop the air conditioner. After 3 minutes, check if it has abnormity. If the collocation of drainpipes is illogical, the water will flow back overfull, which will cause the alarm lamp flashes, even overflow from the water receipt plate. Keep on pouring water until it gives an alarm signal for high water level, check if the pump drains water at once.
