Helium Return and Supply Line Connections
Make the connections between the cryopump and compressor. Refer to
Figure 2-2, while making the component interconnections.
1. Remove all dust plugs and caps from the supply and return
lines, compressor, and cryopump. Check all fittings.
2. Connect the helium-return line from the gas-return connector on the
rear of the compressor to the gas-return connector on the Cryo-Torr
Cryopump.
3. Connect the helium supply line from the supply connector on the
cartridge to the gas-supply connector on the Cryo-Torr Cryopump.
4. Attach the supply and return line identification decals
(CTI-CRYOGENICS supplied) to their respective connecting pip-
ing ends.
NOTE: Verify proper helium supply static pressure as described in the
Installation Section of the appropriate Compressor Manual.
Power Cable Connection
CAUTION
The system power circuit breaker switch at the back of the com-
pressor must be in the OFF position before making any and all
electrical connections.
Do not connect the compressor to its power source until all connec-
tions have been made between the components of the Cryo-Torr
system.
1. Connect the Cryo-Torr power cable from the cold head connector
on the compressor to the Cryo-Torr Cryopump power connector.
