Section 2: INSTALLATION 2.10 2.11 INTRODUCTION This manual has been compiled not only for the care and maintenance of the Welch Dry Vacuum Pump now in your possession, but as a helpful reference and guide to prevent many problems which occur if used improperly 2.20 2.21 UNPACKING Carefully remove the Vacuum Pump from the shipping case and unfasten and remove the wooden skid. Preserve all paperwork for future reference.
2.60 2.61 2.62 2.63 2.64 ELECTRICAL POWER Power Source Review Review the power source and the motor rating to be sure they agree in voltage, phase, and frequency. Serious damage may occur to the motor if it is connected to an improper voltage. All Welch pumps must be grounded. Grounding reduces the risk of electric shock in the event of an electrical short circuit. The plug must be plugged into a properly grounded outlet. Consult your local electrical codes if you have doubts.
The adapter shown in Figure #1 B and C is not acceptable in Canada. 2.65 Extension Cords Motor thermal overload protection is made available by the motor manufacturer as an aid to minimize motor failure. Overload protection is a standard feature on both 50 and 60 Hz single phase-motors. The motors have automatic overload protection. Automatic reset protection is designed to reset itself after a predetermined cooling period.
2.92 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.
Section 3: OPERATION 3.10 3.11 3.12 STARTING PROCEDURES Starting A Welch Pressure/Vacuum Pump Before attaching the pump to a system, familiarize yourself with the function and action of the pressure/vacuum pump that you have acquired. Review the power requirements as described in Section 2.60. Welch recommends running the pump for a few minutes to warm it up, before use. The warm-up improves the pumps ability to handle humid air.
Section 5: TROUBLESHOOTING 5.10 VACUUM PROBLEMS Welch dry vacuum pumps are 100% oil-free. The pump employs a non-lube piston and cylinder. 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.
