Turning Off The Analyzer & Co Purge; Resetting The Microprocessor; Water Trap / Filter Maintenance - Bacharach Fyrite Pro Quick Start Manual

Turning OFF the Analyzer & CO Purge
Press the I/O button to turn OFF the analyzer. The unit will count down
from 5 before turning OFF, thus allowing time for the operator to abort the
turn OFF process by press ing the ENTER button.
If a high CO level is detected at turn OFF, the unit will remain ON with
its pump running and display "PUrG CO". The countdown from 5 will not
begin until the detected CO level drops below 50 ppm. Although not recom-
mended, the purging process can be bypassed by pressing the I/O button a
second time.

Resetting the Microprocessor

If the analyzer 'locks up' and cannot be turned OFF, reset the microproces-
sor by removing one of the batteries for 5 seconds.

Water Trap / Filter Maintenance

The Water Trap / Filter Assembly removes water con den sate from the gas
sam ple, and also prevents soot from con tam i nat ing the internal com po -
nents of the analyzer.
Drain the water condensate after every test.
Procedure:
1. Disassemble the trap (see Figure 4 or 5).
2. Pour out all water condensate; then reassemble the trap.
