1.1 General
The manual provides instructions for installing, oper-
ating and servicing the 8500™ Compressor. If you are
installing or operating a Cryo-Torr® High-Vacuum
System you should also have available the high-vacuum
manual that applies to your particular system:
M8040240: Cryo-Torr 100, 7, 8 and SF High· Vacuum
Pumps
M8040252: Cryo-Torr IO High-Vacuum Pump
1.2 Installation, Operation and
Servicing Instructions
Installation, Operation and Servicing Instructions for
your 8500 Compressor provide easily accessible inform-
ation. All personnel with installation, operation, and
servicing responsibilities should become familiar with
the contents of these instructions to ensure high quality,
safe, reliable performance.
) M8040259: Cryo· Torr 400 High· Vacuum Pump
M8040266: Cryo-Torr 500 High-Vacuum Pump
The manuals for a system cover two basic components:
the high-vacuum pump and the compressor. Each
manual outlines the details necessary for installation,
operation and servicing of that component. A manual is
shipped with each system component (high-vacuum
pump and compressor).
When you purchase a system, you will receive the two
manuals necessary for system installation, plus a loose-
leaf binder with index tab separators, allowing you to
compile a complete indexed notebook.
