Hold the screen up to the light and look through it to make sure it is
clean. All openings in the mesh should be clear. If any of the openings
are blocked, clear them by blowing air through the screen. If the screen
cannot be 100% cleaned, replace it with a new one. A new screen is
included with each new wick.
Examine the white alcohol wick. Some light brownish-yellow
discoloration of the wick is normal. If the wick is severely discolored,
discard it. If the wick is in good condition, it should be removed and
allowed to air dry in a relatively clean location. A spare wick can be
substituted and saturated with alcohol so the instrument can continue to
be used.
Re-assembling the Alcohol Cartridge
Before re-installing an alcohol wick, you must make certain that all
parts are clean. Small bits of the wick or lint can cause serious problems
if they get into the P-T

particle counter.
Inspect the inside surfaces of the alcohol cartridge and the wick retainer
cap. Blow air into them if necessary to make certain that there are no
dust particles present. Blow air onto all surfaces of the Alcohol Wick
that will be used to make certain that any loose particles that may have
shed from the wick are removed.
Drop a clean screen into the wick retainer cap and make sure it lies flat
on the bottom. Examine both ends of the wick. You will notice that one
end is smoother than the other. Slide the smooth end of the wick into the
wick retainer cap and push firmly until the wick hits bottom. Blow
everything off again. See Figure 4-3.
