5.7.1 Changing sample probe filters
The threaded sample probe handle provides
access to the filters. The particulate filter is
held in place by a clear filter cup. To replace
the particulate filter, remove the old filter and
cup, insert a new filter into the cup, and slide
the cup back into place in the probe handle.
The hydrophobic barrier filter fits into a socket
in the rear section of the probe handle. (The
narrow end of the hydrophobic barrier filter is
inserted towards the rear of the handle.)
To avoid accidentally introducing particulate
contaminants into the system, turn the sample
probe upside-down prior to removing either
the hydrophobic filter or the particulate filter.
The following replacement filter kits are
currently available from Honeywell Analytics:

5.7.2 Changing sample probe tubes
(wands)
The standard 11.5” long butyrate probe tube is
held in place with a hex-nut compression
fitting and compression sleeve. The standard
probe tube can be interchanged with other
custom length sections of 1/4” OD tubing, or
probe tubes made of other materials (such as
stainless steel).
Probe tubes are exchanged by loosening the
hex-nut compression fitting, removing the old
tube, sliding the compression sleeve into
place around the new tube, inserting the new
tube into the probe handle, then replacing and
tightening the hex-nut.
Note: The sample probe must be checked
for leakage (as discussed in Section 3.1.1)
whenever filters or probe tubes are
exchanged or replaced before being
returned to service.

MultiPro Pump Maintenance
MultiPro pumps are fairly maintenance free
with the exception of the replacement of the
pump filters on a regular basis.
5.8.1 Replacing pump filters
1. Remove the two screws that hold the inlet
port to the pump.
2. Gently pull the dust filter holder free of the
pump.
3. Remove and replace the dust filter that is
located in the holder.
4. The hydrophobic filter is located beneath
the inlet port in the pump housing. Use a
small screwdriver or other object to punch
through the filter and remove it. The
gasket that sits between the inlet port and
the filter should come out with the filter.
5. Place the new hydrophobic filter with the
filter side down in place of the one
removed in step 4. The gasket should be
located on top of the filter and should sit
against the dust filter holder, which will be
reinstalled in step 6.
6. Replace the dust filter holder (which now
has a new filter in it) and secure it with the
two screws removed in step 1.
6. Direct
programming
In the event that an instrument setting needs
to be changed in the field and a PC with the
appropriate software is not available, the
MultiPro can be programmed directly with the
MODE button.
Reprogramming the
MultiPro is reserved for authorized
personnel. Inappropriate changes made in
the Advanced Menu may lead to inaccurate
and potentially dangerous readings.
6.1
Entering the Advanced Menu
To enter the “Advanced Mode”, turn the
MultiPro off. Then turn the
MultiPro back on, but instead of
releasing the MODE button,
continue to hold it. The “PC
Connect” screen will be shown
in approximately 6 seconds.
Continue to hold the MODE
button for about 5 additional
seconds until the “Config”
screen is shown. Release the
MODE button as soon as
“Config” is shown.
