Make the connections to the oxygen supply at •
this time. Refer to figure 2-2 and 2-3. 1/8” O.D.
nylon pressure hose (HX0012TB024) is used to
connect the oxygen supply. The inlet connection
incorporates a flow restrictor just behind the inlet
connection. When making the oxygen connection,
a back-up wrench should be placed on the restrictor
to insure a secure connection and to prevent over
tightening the flow restrictor. The delivery pressure
for oxygen should be set at 450 psig. To install the
regulator, unscrew the protecting cap from the tank
and inspect the threads on the tank outlet to be
sure they are clean and in good condition. Place
the ball end of the regulator in the tank outlet and
draw up the union nut tightly, keeping the gages
tilted slightly back from an upright position. Open
the tank valve and check for leaks. The bomb must
never be filled to more than 600 psig (40 atm).
Note:
The cause of any leaks must be corrected before
proceeding.
Note:
During extended periods of inactivity (overnight or
longer), close the tank valve to prevent depleting the tank
in the event of a leak. When changing tanks, close the
tank valve prior to re-moving the regulator. Do not use oil
or combustible lubricants in connection with any part of
the oxygen filling system. Keep all threads, fittings and
gaskets clean and in good condition.
The exhaust and vent connections at the rear of the •
calorimeter, are made with the dual tube A1006DD
assembly. The end of the assembly with the bomb
exhaust diffuser should be placed into the 10 liter
carboy (231C2). The carboy should be placed at
or below the level of the calorimeter to facilitate
complete draining of these lines.
Note:
This step is optional for use with A1050DD. See Appendix
G for A1050DD Bomb Rinse Container Installation and
Use.
Connect the printer USB cable between the 1758 •
printer and the connections at the rear of the
calorimeter. Install the printer ribbon and printer
paper at this time. Apply power to the calorimeter
and turn on the printer.
