Installation
During installation, keep the pump and system clean. Avoid touching
surfaces which will ultimately be under vacuum. When the VacIon
pump is open to the atmosphere, take care to avoid introducing
foreign particles, oil, solder flux, or any volatile substances. Before
attaching the pump, clean the system thoroughly. Chemical cleaning
is the most complete cleaning method for the vacuum system;
however, do not attempt it when pockets and crevices exist that will
prevent thorough rinsing. Degreasing with an acetone or methanol
followed by water-rinsing is usually sufficient.
To achieve maximum pumping speed, connect the pump to the
system with a tube that has the shortest length and the largest
diameter possible.
For ultrahigh vacuum work, joints should be tungsten inert gas
welded, hydrogen brazed, or vacuum brazed. Do not use flux in
making joints for ultrahigh vacuum.
Gaskets in the system should be of soft metal such as annealed
copper, aluminium, or gold.
After the pump is sealed in place, leakcheck the entire system.
Assemble the magnet to the pump magnet bracket with the mounting
screws that are provided.
