0
All persons who work with or in the close vicinity of a CryoProbe System must be
informed about its safety issues and emergency procedures.
WARNING: Do not disconnect any tube or cable from a running CryoProbe Sys-
tem unless W
ARM and UNPLUG light up on the CryoCooling Unit front panel.
If in doubt: Put on goggles and protective gloves!
WARNING: Do not manipulate connectors, screws, valves or pressure relief
valves other than those that are explicitly described in the CryoProbe System
manuals for operator use.
Inherent safety
The CryoProbe System is designed for inherent safety. Pressure relief valves,
sensors, and error handling in hardware and software have been included to pro-
tect operator, equipment, and environment.
CE certification
CryoProbe, CryoCooling Unit and He Compressor are CE certified.
Technically qualified personnel only
Only persons with a basic technical understanding of electricity, pressurized gas
systems, and cryogenics should operate and maintain a CryoProbe System. User
interface, system messages, and manuals require a good understanding of the
English language.
No user-serviceable parts inside
There are no user-serviceable parts inside a CryoProbe, a CryoCooling Unit cabi-
net, a He Compressor, or any other component of a CryoProbe System. Do not
open these devices.
B
RUKER warranty expires if the CryoProbe was opened by unauthorized per-
sonnel.
WARNING: Two persons are required to lift the heavy panels of the CryoCooling
Unit. Be careful with the panels, there might be sharp edges on their inside which
could cause injuries.
WARNING: If you have to work with an open CryoCooling Unit cabinet, put on
protective goggles and gloves.
Pressurized cold helium gas cycle
The CryoPlatform works with helium gas (He) that is pressurized up to about
25 bar and cooled to cryogenic temperatures around 20 K. All pressurized parts
are kept in strong enclosures which are designed to hold back gas jets or ejected
particles in case of a rupture. If unprotected skin is exposed to cold He, severe
cold burns are possible.
The helium gas volume inside the cryogenic cooling cycle is small and presents
virtually no danger of suffocation. However, the He steel-cylinder contains a sub-
stantial gas volume, note the warning below ("Pressurized helium gas supply"
on page 10).
