Preventive maintenance comprises of the following activities:
• Perform visual inspection (see “Inspecting the Instrument” on page 3-4)
• Check the operating time for the IR lamp (IR SourceTime), pump and CO
2
scrubbers
(Pump OpTime).
• If required, (operating time >15,000 hours), replace the infrared Lamp, the pump and the
CO
2
scrubber, and reset the appropriate operating time counters.
• Perform barometric pressure check and calibrate, if necessary, see “Barometric Pressure
Check and Calibration” on page 4-13.
• Perform leakage check, see “Leakage Check” on page 4-14
• Perform Pump Check
• Perform flow check and calibrate, if necessary, see “Flow Rate Check and Calibration” on
page 4-15.
• Perform Noise Check
• Perform CO
2
calibration check; check the date of the last calibration and calibrate, if neces-
sary, see “CO2 Gas Measurement Calibration Check” on page 4-16.
• If calibration done, perform CO
2
calibration verification using 2nd calibration gas
• If M3015A has been opened, perform a system safety test, see “Patient Safety Checks” on
page 4-24.
