Open each valve slowly, you will hear the air rush out as the pump pulls the air. Slowly continue to fully open. Open each valve as the pressure is pumped down to the pressure in the next lowest line. Ideally, you don't want to allow pressure from one line into the line of a lower pressure line. The final pressure should be around 1.0 Torr in each line when you leave the lab area if all six lines are opened. The pump will normally bring all 6 lines down to .2-.3 Torr after about an hour.

The S1 and S2 lines leak the most during the day and will read the highest in the afternoon when you return, usually between 30-40 Torr in the summer and 20-30 Torr in the winter. Note any unusual vacuum readings as they can indicate a leak beyond what is normal. Sometimes a line isn't pumped down the night before and can read higher than 30 Torr. Pump down the highest ones first as stated above. |
