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 tools to open or close the vessel. If the vessel fails to deflate use the pre-scribed
'emergency deflate' procedure as outlined in the CAL3K-F Operations Manual, which uses the 3K-3-18
EMERGENCY DEFLATE tool (3K-3-18).
• Use the provided De-filler cap only, part number: 3K-3-22.
• 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.
A SUITABLE INSPECTION WARNING PERIOD OF 2000 FIRINGS, AND A STOP OPERATING LIMIT OF
•
2500 FIRINGS ARE PRE-PROGRAMMED FROM THE FACTORY
THE VESSEL MUST BE INSPECTED AT REGULAR INTERVALS DEPENDING ON THE USE. A SUITABLE
INSPECTION PERIOD CAN BE SET (By your agent!) AND THE UNIT WILL ISSUE AN INSPECTION
WARNING AND SOON AFTER THIS IT WILL SHUT-DOWN THE OPERATION.
NOTE: THE MANUFACTURER (DDS) AND ITS AGENTS CANNOT BE HELD RESPONSIBLE FOR ANY
LOSS OR DAMAGE RESULTING FROM NEGLIGENCE OR INCORRECT USE OF THEIR EQUIPMENT.
IT IS YOUR DUTY AND RESPONSIBILITY TO CHECK ALL SAFETY ASPECTS OF THE CAL3K-F
SYSTEM REGULARLY.
