2.10 Introduction This manual has been compiled not only for the care and maintenance of the Welch Dry Vacuum System now in your possession, but as a helpful reference and guide to prevent many problems which can occur if used improperly. -
Page 6: Electric Power
Serious damage may occur to the system if it is connected to an improper voltage. All Welch systems must be grounded. Grounding reduces the risk of electric shock in the event of an electrical short circuit. The plug must be plugged into an outlet properly grounded. Consult your local electrical codes if you have doubts. -
Page 7: Vacuum Connections
Hose clamps should be used to hold the hose in place. Since all six models operate in the viscous flow range, the small diameter of the hose will generate minimal conductance loss. For best results, Welch recommends the length of the tubing between the pump and the chamber be kept as small as possible. - Page 8 The symptom of a high water vapor load is if you have droplets coming out of the exhaust port. If you see droplets of water, Welch recommends you use a cold trap to capture the water before entering the pump or dilute the water vapor stream by adding dry nitrogen to the gas flow. Please call our customer service department for additional information at (847) 676-8800 Ext.

Page 9: Section 05 - Operation
Review the power requirements as described in Section 2.6. Welch recommends running the pump for a few minutes to warm up before use. The warm-up improves the pump’s ability to handle humid air. - Page 10 Section 5: TROUBLESHOOTING 5.10 Vacuum Problems Leakage, contamination and unusual outgassing are the general causes of problems with poor vacuum. To operate at maximum efficiency a system must be thoroughly clean. If the system is completely clean and free from leaks, and unwarranted vacuum problems still exist, the pump should be checked. A simple criterion for the condition of the pump is the determination of its maximum vacuum capability.
