Replacement of the Pump and CO
2
Scrubber
Replacement of the Pump and CO
2
Scrubber is supported for units with serial number
prefix DE020xxxxx only. Where a recommendation is made to replace the Pump and CO
2
Scrubber, this applies only to these earlier units. If the Pump and CO
2
Scrubber are defective
in later units with serial number prefix DE435xxxxx, repair is effected by M3015A unit
exchange.
The procedure for replacing the Pump and CO
2
Scrubber is found in "Repairing the
Instrument".
The effectiveness of the Pump and the CO
2
Scrubber gradually decreases over time. As a
result, periodic replacement is necessary.
Philips recommends replacement as follows:
• After 15,000 hours of use (check “Pump Op Time”. See “Checking and Resetting Time
Counters” on page 153).
• If the Instrument requires repairs, check the time counters, and replace the Pump and CO
2
Scrubber if necessary, in addition to any other repairs.
NOTE After fitting the new part(s), go to Service Mode and reset the counter for the part(s) you have
replaced. The procedure for resetting the counters is found in "Repairing the Instrument".
When the PumpOpTime has been reset an INOP will be generated: “CO
2
OCCLUSION”. To
clear this INOP you must perform a flow check and store the flow in Service Mode (select
“Store Flow”).
Replacement of the Infrared Lamp
The infrared lamp can be exchanged only in units with serial number prefix DE020xxxxx
manufactured before June 2002. The support strategy for later units in case of an infrared
lamp failure is M3015A unit exchange.
General Cleaning of the Instrument
The Monitor, the Measurement Server, and the Measurement Server Extension should be
kept free of dust and dirt. In particular, exterior cleaning of the Monitor’s case and LCD
screen is recommended. Clean the case with a lint-free cloth or sponge, moistened with either
soap and water, a diluted non-caustic detergent or one of the cleaning agents listed in this
chapter. Universal Display Cleaner or window cleaner is recommended for the cleaning of
the LCD screen.
Full cleaning instructions are given in the Instructions for Use.
