Changing the Alcohol Wick
The wick inside the Alcohol Cartridge may be changed in the field. Two
spare wicks are included with the P
ORTA
C
OUNT
®
P
RO
Respirator Fit Tester.
Normally, the wick does not need to be changed unless one of the following
problems develops:
•
Moisture accumulates in the wick and causes the Low Alcohol Level
message to come on even when there is an adequate alcohol supply.
This may happen when the P
ORTA
C
OUNT
®
P
RO
fit tester is used
extensively for weeks on end. Especially if you are fit testing in an area
with high humidity.
If moisture accumulation occurs, the Alcohol Wick can be removed,
allowed to dry, and then re-installed into the Alcohol Cartridge.
•
The wick becomes contaminated with dirt, oil, or other foreign
substances. This should not happen unless the instrument is used to
sample aerosols other than those normally found in ambient air.
If the Alcohol Wick is contaminated, it should be discarded and
replaced with a new one. Note that some discoloration of the wick is
normal and will not influence performance.
To remove the Alcohol Wick from the Alcohol Cartridge:
1. Grasp the cartridge with both hands. With your thumbs near the seam,
firmly apply pressure as if you wanted to break it into two pieces. The
cartridge should snap apart exposing the end of the white Alcohol Wick.
2. After separating the two halves, push the Alcohol Wick out of the Wick
Retainer Cap from the opposite end with the Wick Removal Tool (wood
dowel) provided with each new alcohol wick. Do
not use a pencil point
because bits of lead could break off.
