➨
Adopt suitable measures to prevent the formation of
explosive or flammable mixtures, use inert gas for
venting if necessary.
➨
Prevent the discharge of dangerous gases and vapors
to the surrounding atmosphere. If appropriate, connect
the exhaust line to a suitable treatment system.
➨
Adopt suitable measures to prevent the release of
dangerous, toxic, explosive, corrosive, noxious or pol-
luting fluids, vapors and gases when disposing of con -
densates.
+
Cold surfaces can absorb a great amount of gas, which
may expand abruptly in case of warming. This may lead
to unmanageable overpressure in the system, creating
a risk of bursting!
+
Check the coolant level of the condenser at appropri-
ate intervals.
+
Attention: Coolant may overflow unexpectedly, e.g.,
in case of large amounts of gas.
+
Do not overfill the condenser. Lowest permissible cool -
ant temperature: -112°F (-80°C).
+
Maximum operating pressure: 16 psi (1.1 bar) abso-
lute.
+
Never block the gas outlet ((6) hose nozzle for tubing
I.D. 3/8” (10 mm)). The exhaust hose has always to be
unobstructed and without back pressure to enable an
unhindered discharge of gases and protect the pump
valves from damage.
• Prior to every use: Inspect the condenser for faults.
There must be no damage on the glass surfaces. Do
not use damaged components.
• Use only transport receptacles intended for coolants.
• Use safety glasses and protective gloves.
• Do not clamp the covers of condensers or coolant re -
ceptacles. Allow pressure equalization between cool-
ant and atmosphere.
• Comply with all applicable safety measures and re -
quirements when using cryogenic coolants.
