The accessory ET 150.01 is used to evacuate and fill refrigeration systems. The refrigeration system is evacuated using a vacuum pump. Evacuation using the vacuum pump removes air and humidity from the refrigeration system to allow subsequent filling with refrigerant. The correct amount of refrigerant is monitored using the filling balance. The equipment is designed for the CFC-free refrigerant R134a.
