4 INSTALLATION
4.1 UNPACKING AND INSPECTION
There are no special precautions to be taken when unpacking your system. The following check list is for
your convenience:
1. Locate and tick-off the various system components as indicated on the CAL3K-ST Check List as
per above.
2. Unpack and inspect all the system components such as the 3K-ST Calorimeter, 3K-3 Filling
Station and the 3K-5S Standard Vessels according to the instructions in the relevant sections in
this document.
3. Inspect everything for any physical damage during transit. If damaged, consult your Agent
immediately.
4. The Calorimeter has a GROUND (SAFETY EARTH) lug at the rear panel. This lug MUST be
connected to the EARTH supply to ensure operating personal safety in case the power supply
fails.
5. Connect the power supply to the mains power and to the Calorimeter. Any power supply with
12V output, 1000mA capacity, centre pin POS, can be used.
6. Observe that the Display on the Calorimeter comes ON. If not, check the mains connections or
consult your Agent immediately.

4.2 SETTING UP
4.2.1 PREREQUISITES
Prior to installation of the CAL3K-ST System, the User must provide the following:
1. A mains outlet for the 3K-ST Calorimeter and a mains outlet power supplies.
2. A supply of oxygen at a pressure of 3.0Mpa (30bars) (3000Kpa) within 4 meters of the 3K-ST
Calorimeter. If bottled oxygen is used, a suitable high-pressure oxygen regulator must be
supplied. Digital Data Systems can supply a single stage high-pressure oxygen regulator; contact
your agent for more information.
3. If a balance is supplied, ensure that a sturdy, stable weighing surface is available. A mains outlet
and Balance connecting cable will also be required (balance cable supplied as part of kit).
4.2.2 SITE SELECTION
The 3K-ST Calorimeter is a desktop unit, which can be installed wherever the laboratory space
permits, with two restrictions:
1. The CAL3K-ST system, consisting of 3K-ST Calorimeter, should be connected to a mains circuit
without heavy inductive or SCR switched equipment. It is safe to have balances or other small
electronic apparatuses on the same circuit. Good installation practice would be to have a
separate fused mains circuit with separate earth leakage supply (or an earth current monitor, if
applicable) for every system component. Future computers and peripherals installed can be
connected to the same circuit.
2. The unit should be located in a place with a stable temperature, not in direct sunlight or in the
outlet path of an air conditioner.
Please see above for the dimensions, weights and power requirements per unit. The BALANCE
data would be dependent on the make and model that you will be using.

5 SAFETY PRECAUTIONS
5.1 CALORIMETER (3K-ST)
• Connect the safety earth to the EARTH STUD on the back of the instrument. This is required
when the external power supply fails
• Do not open the CAL3K for any reason whatsoever! There are no serviceable parts inside the
unit.
DO NOT TAMPER WITH THE EARTHING - CONSULT A QUALIFIED ELECTRICIAN SO THAT THE
EARTHING CAN BE CHECKED.
5.2 FILLING STATION (3K-3)
• Install the flexible high-pressure pipe supplied without any sharp bends.
• Check the nylon high-pressure pipe supplied for any mechanical damage before putting it under
pressure.
• Secure the pipe into the ferrule connector and screw the connector to the pressure regulator
side. Secure the pipe nuts to the pressure regulator side, then clamp the ferrule to the high
pressure pipe on the gauge block side.
• If the oxygen bottle is not situated close to the Filling Station or if it is in another room or
perhaps outside, then a solid, permanent installation of pressure piping should be installed, as
well as a shut off valve and pressure gauge within easy reach of the 3K-3 Filling Station.
• If bottled oxygen is used, a suitable High Pressure oxygen regulator must be supplied by your
Agent, or sourced locally. Ordering this item from the factory ensures that the necessary
modifications have been made to fit the 3K-3 Filling Station.
• The oxygen bottle should be secured according to regulations.
• Secure the pipe to the side of the filling through the supplied device
• 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.
• DO NOT USE ANY OTHER PIPE OTHER THAN THE HIGH PRESSURE PIPE SUPPLIED FOR OXYGEN
FILLING.
• DO NOT USE THE HIGH PRESSURE PIPE IF IT HAS A SHARP BEND OR KINK, DISCARD
IMMEDIATELY
• ALWAYS FILL THE VESSEL WITH OXYGEN TO A MAXIMUM PRESSURE OF 3000KPA (30 bar).

Digital Data Systems (Pty) Ltd.
CAL3K Advanced Bomb Calorimeters
www.ddscalorimeters.com
• NOTE: With some applications you may need to fill the Vessel to less than 3000KPA e.g.
1500KPA (15 bar), however this is only applicable when you have a sample which is highly
combustible, for example with wood related samples.
• REMEMBER: You may fill the Vessel LESS than 3000KPA but NEVER more than 3000KPA.
5.2.1 HIGH PRESSURE OXYGEN
• The type of Oxygen to be used is the standard Industrial Oxygen used for welding. A purity
of 99.5% will be suitable.
• Conform to the industry standard of handling procedures for oxygen bottles.
• Secure the bottle against a wall.
• Should the Oxygen supply be in another room, make sure there is a high pressure shut off
valve near the 3K-3 Filling Station installation.
5.3 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.
• 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. 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

is the standard for bomb calorimetry.
• 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.
7 HARDWARE TEST
The hardware test is activated with the F9 function key. Press F9, ENTER
The test needs no further instruction but requires that the LID is closed when instructed to do so. The
test can be terminated at any time with the ESC key. If a test fails, it can be terminated with the F8 key.
The vessel can be tested with the F7 key. The vessel must have a firing wire attached to the electrodes
but needs no oxygen. Close the lid and test each vessel.
