Page 5: Section 2: Installation
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: Overload Protection
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. 2.29... -
Page 8: Section 3: Operation
Operating Pressure Range Models 2560, 2561, 2565, 2580, 2581 and 2585 Dry Vacuum Pumps are designed to be run from atmospheric to their maximum vacuum level on the intake side. Consult the Specification Table in the back of this manual for the ratings for your specific model. -
Page 9: Vacuum Problems
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. -
