Section 03 INSTALLATION 3.10 INTRODUCTION This manual has been compiled not only for the care and maintenance of the Welch Dry Dual Function Pressure/Vacuum pump now in your possession, but as a helpful reference and guide to prevent many problems which can occur if used improperly. 3.20 UNPACKING Carefully remove the Pressure/Vacuum pump from the shipping case and unfasten and remove the wooden skid. Preserve all paperwork for future reference.
Section 04 ELECTRICAL POWER 4.10 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. 4.
5.11 The Care of a Trap When using a cold trap the refrigerant should be maintained at a high level in the flask to keep the trap at a uniformly low temperature. If the trap is rewarmed it may allow re-evaporation of the condensate. The refrigerant add tube on the liquid nitrogen trap should not be obstructed as the refrigerant boil-off can pro- duce dangerously high pressures. If the trap becomes saturated it should be disconnected from the system, drained, and cleaned.
Section 08 TROUBLESHOOTING 8.10 VACUUM PROBLEMS Leakage, contamination, and unusual outgassing are the general causes of problems associated with poor vacuum. To operate at maximum efficiency, a system must be thoroughly clean. It 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.
Section 10 WARRANTY UNPACKING Inspect the pump carefully. If any damage has occurred, file claim with the carrier immediately. Save the shipping container for carrier to inspect. OPERATING PUMP Refer to the enclosed Instruction/Operation Manual for all information to properly operate and maintain the pump. WARRANTY This Welch Vacuum product is warranted to be free from defects in material and workmanship.
