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 se-
curely 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 condition 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 clean-
ing.
