Install the Cryosurface
This section describes how to install the cryocoil or cryobaffle, and refrigerant lines. If these items are
not already selected, then follow the recommendations below.
•Refer to System Summary on page 1-3 and Cryocoils and Refrigerant Lines on page 3-10 for
cryosurface information.
•Refer to Appendix F: Feedthroughs on page 12-10 for feedthrough selection information.
• Contact Brooks Automation Polycold Systems for more information.
NOTE: This task assumes that both a cryosurface and a standard 50mm (2-inch) feed-through
from Brooks Automation Polycold Systems are being installed.
If a cryobaffle or cryocoil and feed-through has been custom-fabricated by a source other
than Brooks Polycold, verify that the part meets the specifications in the section Specifica-
tions and Site Requirements, Cryocoils and Refrigerant Lines on page 3-10.
The feed-through on the Brooks Polycold Systems Cryocoil is designed to be installed from the inside
of a vacuum chamber. This allows removal of the cryosurface when cleaning or servicing the vacuum
chamber.
Install the Feed-Through and Cryocoil
1. Inspect the feed-through port thickness, hole diameter, and sealing surface. Ensure
that the feed-through port is compatible with the feed-through.
2. Clean the inner and outer surfaces of the feed-through port on the vacuum chamber wall where the
cryosurface feed-through is to be installed.
Item Description
Electrical Category Type 1 – Equipment is fully de-energized
Tools 2.5 inch Spanner wrench, p/n 810030-07, for the nut on
feedthrough connection
Materials High-vacuum grease - must have an appropriate low vapor
pressure (for optional use on the feed-through's)
O-ring, as required
High Working Pressure
The refrigeration unit's working pressure may exceed the cryosur-
face's working pressure which may damage the vacuum system
components and may result in equipment damage and personal
injury.
• Do not use reservoir type cryosurfaces.
• Do not connect the refrigeration unit to a cryosurface without first
verifying that the cryosurface meets specifications.
