8.5 Pneumatic Line Inspection
Particulate matter in the pneumatic lines will affect both flow rate and response time. It is
important that the pneumatic system be periodically inspected and thoroughly cleaned if
necessary. Clean by disassembling and passing methanol through three times. Dry with nitrogen
or suitable clean zero air.
Also inspect all pneumatic lines for cracks and abrasion on a regular basis. Replace as
necessary. Refer to the pneumatic diagram in Figure 8-5, Figure 8-6.
