4.8. Clock Battery
The Clock Battery (page 10) maintains the correct date and time when AC power is not applied to the
monitor. Replace this battery about every 5 years (P/N 0204-0020).
4.9. Sample Pump
The Sample Pump (page 10) 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
a new sample pump (P/N 3015-5176).
