CAUTION
The use of several compressors on a single manifold feeding a common
supply header and a common return header requires special
precautions. Contact CTI-CRYOGENICS for a review of the intended
installation and for specific technical instructions. The use of a 9600
compressor on a manifold with other CTI-CRYOGENICS compressor
models requires a reduction of the helium charge pressure to 200 - 210
psig charge pressure to avoid helium safety valves from inadvertently
venting. Refer to Section 4 - Operation and Section 5 - Maintenance
for more information.
1. Connect the Supply and Return lines to the 9600 Compressor as
described in Connecting/Disconnecting Helium Flex Lines
within this section.
2. Connect the Gas Return Line to the customer supplied helium
manifold and then to the GAS RETURN connector on the
On-Board Cryopump.
3. Connect the Gas Supply Line to the customer supplied helium
manifold and then to the GAS SUPPLY connector on the On-Board
Cryopump.
