Expelling Air from Pipes
Air and humidity left inside the refrigerant circuit can cause compressor
malfunction. After having connected the indoor and outdoor units, bleed the
air and humidity from the refrigerant circuit by following the below steps.
1. Take off the cover from the stop valve and T-branch valve.
2. Take off the auxiliary cover from the T-branch valve.
3. Turn the stop valve rod anticlockwise to an angle of 90 degrees, keep it
open for 8 seconds and then close the valve.
4. Check whether there is air leakage at all connection parts of the pipes.
5. Push the top rod of the T-branch valve with a hexagon wrench to expel air.
6. Repeat the third and fifth steps.
7. Open the stop and T-branch valve with a hexagon wrench to start
operation of the unit.
IMPORTANT: Check all piping and connections and ensure there is no
leakage. Test the unit with soapy water for leakage.
