Analyzer Instruction Manual, 02246, Rev. G, DCN 5247

9.3.10 Pneumatic System

The pneumatic system is diagramed in Table 8-8-6, Table 8-8-7, Table 8-8-8, depending on

which options the instrument was ordered with.

9.3.10.1 Leak Check

CAUTION

When doing a leak check do not pressurize

the M200A to greater than 15psi.

Damage to internal components will

occur at higher pressures.

The basic cause of many performance problems is a leak. Refer to Section 8.9 for the leak check

procedure.

9.3.10.2 Pump

The external sample pump is capable of maintaining the cell pressure at 5"Hg-A. If higher

pressures are noted, the pump may need servicing. Check the pump/ozone scrubber for leaks or

rebuild pump.

The internal sample pump pressures tend to run slightly higher than the external pump due to its

smaller size. As in the case above, if higher pressures are noted the pump may need servicing. In

the internal pump configuration, the ozone scrubber is integrated into the molybdenum

converter.
