[Opera-CONNIE] Fwd: Pump picture

Wed Jan 14 17:05:49 BRST 2015

Hello,

I would suggest to start making the arrangements today, and wait until tomorrow to disassemble the pump.

Few things:

0) read manuals, understand the procedure, be sure you have the necessary tools,  check that the steps to follow are reasonable.

1) make sure the pump is unplugged before starting handling it.

2) we will need to remove the vacuum pipe from the pump. After doing that we need to cover the pipe and the pump with plastic covers. Try to find two of those in one of the boxes in the shelf. Using nitrile gloves, clean the plastic covers with alcohol wipes before placing them in the pump/pipe. There should be a package of these wipes in the container.

3) turn off the vacuum gauge display, the one that shows the pressure. Unplug it from the outlet. Remember the outlets we are using for the equipment.

4) disconnect the cable at the top of the gauge, at the vacuum pump end. Be sure there is no extra cable connected to the pump.

5)open the purge screw at the back of the pump. It will release the vacuum in the pipe. Make sure the valve on the detector is close.

6) disable the clamp that holds the vacuum pipe to the pump. When you disable it, there is one Oring in the midle of the junction, with a metal frame. Do not drop it on the floor. Remove it, and put it in a clean place (Could be between two of those plastic covers, or cover it with clean wipes). Put the two plastic covers on the pipe/pump holes. There are a few more Oring in the vacuum box in the container, if you want to be familiar with them. Those pipe/Oring/covers are size 40.

7)remember to use grounding wristband when you are handling the pump connected to the detector through the vacuum pipe.

8)completely clean the workbench. 

9) move the pump to the workbench. The pump is really heavy. Be sure you have a clean path when moving the pump. Do not step on the cryo pipes.

10)double check instructions on the manual. One of the steps is to remove the top part of the pump case, together with the turbo pump and the gauge. Be sure you have enough space on the bench. Be careful when you  place it on the bench, the weight of the turbo pump and gauge might cause it to fall. If you need it, there are soft materials on the wooden box in the container in the boxes. Be sure the material is clean.

11) good luck!!

Guillermo
