This product is for use on a nominal 120V circuit, and has a grounding plug that looks like the plug illustrated in Sketch A in Figure #1. A temporary adapter, which looks like the adapter illustrated in sketches Band C, may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a properly grounded outlet is not available. - Page 8 2.30 Traps 2.31 The need for a Trap The pumps will handle humid air. All wetted aluminum parts are treated for corrosion protection from moisture. All other wetted parts are stainless steel. If there is a chance liquid may be drawn from the process under evacuation, Welch recommends a liquid trap be placed between the process and the pump.

Section 3: OPERATION 3.10 Starting Procedures 3.11 Starting a Welch Dry Vacuum Pump Before attaching the pump to a system it is well to familiarize yourself with the function and action of the pressure vacuum pump that you have acquired. Review the power requirements as described in Section 2.6. - 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 effi ciency 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.
