4. Before re-installing the alcohol wick, make certain that all parts
are clean. Small bits of the wick or lint can cause serious
problems if they get into the PortaCount Pro
fit tester.
5. 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.
6. 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.
7. Check both ends of the wick. If one end is smoother than the
other, slide the smooth end of the wick into the Wick Retainer
Cap first. Otherwise, simply insert the wick and push firmly until
the wick hits bottom.
8. Blow everything off again.
9. Align the two halves of the Alcohol Cartridge and press firmly until
they snap together.

with a rise in humidity. Under normal conditions with a dry wick freshly
charged with isopropyl alcohol, the PortaCount fit tester will operate

PortaCount fit tester in higher humidity. To keep this average run time
