Sampling pump
When approaching the end of the specified lifetime of the pump, it will consume higher amount
of energy and reduce its sample draw capability significantly. When this occurs, it is necessary
to replace or rebuild the pump. When checking the pump flow, make sure that the inlet
connector is tight and the inlet tubing is in good condition. Connect a flow meter to the gas
inlet probe. The flow rate should be above 450 cc/min when there is no air leakage.
If the pump is not working properly, refer the instrument to qualified service personnel for
further testing and, if necessary, pump repair or replacement.
Cleaning the instrument
Occasional cleaning with a soft cloth is recommended. Do not use detergents or chemicals.
Visually inspect the contacts at the base of the instrument, on the battery, and on the Charging
cradle to make sure they are clean. If they are not, wipe them with a soft, dry cloth. Never use
solvents or cleaners.
Special servicing note
If the instrument needs to be serviced, contact either:
1. The Honeywell distributor from whom the instrument was purchased; they will return the
instrument on your behalf.
or
2. The Honeywell Technical Service Department. Before returning the instrument for service
or repair, obtain a Returned Material Authorization (RMA) number for proper tracking of
your equipment. This number needs to be on all documentation and posted on the outside
of the box in which the instrument is returned for service or upgrade. Packages without
RMA Numbers will be refused at the factory.
