System Inspection
Inspection and maintenance should be done only by qualified personnel.
1. With Snoop
®
PN 202887000 or a soap solution, check the sample line
for leaks.
2. Verify that flowmeters, regulators, valves, gauges, and filters are in
good condition and securely mounted.
3. Verify the integrity of all power supply and interconnecting wiring.
Check the circuit cards in the field unit and controller for signs of
overheating or contamination. Use clean, low pressure air to blow off
any accumulated dust and debris.
4. Repair or replace any damaged part. Correct any unsatisfactory condi-
tion as necessary.
5. Exterior enclosures of the field unit and sample system can be cleaned
with mild, non-abrasive detergent or spray cleaner. The controller
enclosure can be cleaned in the same manner but the cleaner must
not be sprayed or applied directly. Moisten the applicator first before
cleaning.
