Warnings and Cautions
WARNING:
Always disconnect AC power before working inside the monitor.
CAUTION:
When working inside the monitor, be very careful not to dislodge any
electrical wiring or pneumatic tubing. The AGMSZ contains sensitive electronic
components that can be easily damaged. Be careful not to touch or disturb any of these
components that can be easily damaged. Be careful not to touch or disturb any of these
components.
Hydrophobic Filters
Hydrophobic Filters (Page 8) located in both the gas-sample and purge lines prevent water from entering
the IR detector. A zone flow fault will occur (fault code <0800>) if the gas-sample filter becomes blocked,
the IR detector. A zone flow fault will occur (fault code <0800>) if the gas-sample filter becomes blocked,
while a purge flow fault will occur (fault code <1000>) if the purge filter becomes blocked. Replace the
appropriate filter as required (P/N 07-1650).
Servicing Air Lines & Termination Filters
The gas-sample line and the optional purge and exhaust lines should be periodically checked for obvious
signs of kinks, damage, and contamination. Replace the tubing as required (P/N 304-2742).
The gas-sample line and purge-line termination filters prevent dust and dirt from entering the monitor.

Fuses
The AGMSZ is protected from electrical damage by two, 1 A, 250 V, type “F” fuses (Page 8). Carefully
remove the fuses from their fuse clips and visually inspect each fuse for damage. Replace the fuses as
required (P/N 04-2620).
required (P/N 04-2620).
Clock Battery
The Clock Battery (Page 8) maintains the correct date and time when AC power is not applied to the
monitor. Replace this battery about every 2 years (P/N 204-0020).
monitor. Replace this battery about every 2 years (P/N 204-0020).
Sample Pump
The Sample Pump (Page 8) draws the gas sample into the monitor, through the IR detector, and
discharges the sample out the monitor’s exhaust port. When replacing the pump, remove its inlet and
outlet tubing, disconnect the AC power wires from the pump itself, and remove pump from monitor. Install
outlet tubing, disconnect the AC power wires from the pump itself, and remove pump from monitor. Install
a new sample pump (P/N 3015-4239).
