Maintenance & Troubleshooting
Oxygen Bomb
Under normal usage the 1108P Parr Oxygen Com-
bustion Vessel will give long service if handled with
reasonable care. However, the user must remember
these bombs are continually subjected to high tem-
peratures and pressures that apply heavy stresses
to the sealing mechanism. The mechanical condition
of the bomb must therefore be watched carefully
and any signs of weakness or deterioration should
be replaced before they fail.
It is recommended the 1108P Oxygen Combustion
Vessel have O-rings and valve seats replaced after
6 months, 500 firings or at more frequent intervals
if the bomb has been subject to heavy usage or if it
shows any evidence of damage. Detailed informa-
tion can be found in Manual 418M supplied as a
part of this manual. This 1108P Oxygen Combustion
Vessel is the only part of the calorimeter system that
requires routine maintenance. All other problems
will require diagnosis and parts replacement.
Fuses
The replacement of protective fuses for the 6100
Calorimeter should be performed by qualified
personnel.
Note: Check the labels on the instrument for
correct fuse rating.
