Evacuation
Connect the charge hose end to the vacuum pump to evacuate the tubing and indoor unit.
Confirm the Lo knob of the manifold valve is open.
Then, run the vacuum pump.
The vacuum pump must be operated at less than 0,8torr of the gauge pressure
When the desired vacuum is reached, close the Lo knob of the manifold valve and stop the
vacuum pump.
Charging and finish
1. Use a wrench to turn the valve stem of liquid side valve counter- clockwise to fully
open the valve
2. Turn the valve stem of gas side valve counter-clockwise to fully open the valve
3. Loosen the charge hose connected to the gas side service port slightly to release the
pressure, then remove the hose
4. Replace the flare nut and its bonnet on the gas side service port and fasten the flare
nut securely with an adjustable wrench.
This process is very important to prevent leakage from the system!
5. Replace the valve caps at both gas and liquid side service port and fasten them tightly
This completes air purging with the vacuum pump and fill the whole system with refrigerant.
The DC split Air condition 3500 is now ready for its´ first test run.
