OXYGEN CONNECTIONS
Install the high-pressure oxygen pipe without any sharp bends. A 4mm pipe connection is provided on the
CAL3K. The oxygen source connection depends on the installation (oxygen regulator or piped in oxygen).
It is important that the oxygen connection is secure.
6.3
EXHAUST CONNECTION
It is advisable to route the exhaust gases to the outside or through a water trap. If no exhaust pipe
is installed then the exhaust noise is startling to say the least.
The unit is supplied with a 4-metre length of black plastic pipe and an O-ring (3K-6-031). Unscrew the
plastic exhaust nut (no tools!), insert the exhaust pipe, put the O-ring over the pipe, and screw the nut in
to the exhaust housing. Tighten by hand!
Note: There is no pressure in this pipe!

COOLER (3K-2)
• There are no user serviceable parts inside.
6.5
VESSEL (4K-4)
• Handle the vessel over a table or solid surface.
• Do not drop a vessel.
• Do not overfill a vessel with oxygen: The maximum oxygen filling pressure is 30bar / 3000kPA, which
is the standard for bomb calorimetry.
• Do not use any oil or grease on any of the oxygen fittings or the O-rings. A very small amount of high-
pressure (vacuum) grease is allowed on the O-ring to make them pliable. Wipe them clean afterwards.
• Store the vessel with the lid open. Never store a vessel under pressure, always deflate using the de-
filler cap.
• Clean the inside of the vessel with paper towel after every use.
• Weigh the crucible every week and discard it when it has lost 10% of its original mass.
• Discard the crucible when the bottom is distorted and extremely discoloured.
• Remove the deflector plate every week and clean the top surface. It does accumulate residue and
must be clean regularly.
• Make sure to use the pipe-clamping device on the right side of the filing station for safe use.
NEVER OPERATE ANY UNSAFE VESSEL.
•
NEVER IMMERSE THE VESSEL INTO COLD WATER WHEN COOLING. USE THE 3K-2 AIR
•
COOLER OR ALLOW THE VESSEL TO COOL DOWN NATURALLY.
