Installation
Install the Cold Head Cable
1. Connect one end of the cold head cable to the cold head receptacle on the compressor.
2. Connect the other end to the cold head cable receptacle on the cryopump.
Connect the Purge Gas, Vacuum and Vent Lines
AVOID ASPHYXIATION. Be sure that the work area is will ventilated.
1. Connect a supply of clean, dry nitrogen gas to the nitrogen purge port.
EXPLOSION HAZARD. AVOID INJURY. Never use compressed gas from a
cylinder without a proper regulator. Overpressure can cause serious injury if the
system equipment ruptures. Always wear eye protection when handling
pressurized gas lines and other pressurized equipment.
2. Connect the roughing line to the pumpout port. Use a pipe or hose with an inside diameter
as large as possible to maximize pumping speed. The roughing line should contain a valve
to close to isolate the roughing pump.
3. Connect a temperature-sensor cable from the temperature controller/indicator to the
temperature-sensor connector.
EXPLOSION HAZARD. AVOID INJURY. A relief valve or a rupture disc must
always be installed on a cryopump.
Do not remove, modify, block or restrict any pressure relief devices. Material
failure and resulting pressure release can cause serious injuries.
AVOID INJURY. If flammable, corrosive or toxic gases are cryopumped, a vent
pipe must be connected to the relief valve or the rupture disc outlet. Vent to a
safe location.
