ET 910.13 is used to fill and evacuate refrigeration systems as well as performing maintenance tasks and troubleshooting. The maintenance set includes a filling station, a set of tools, a digital multimeter, and a leak detector. The components used are common in refrigeration and therefore closely related to practice.
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 refrigerant R513A.
