76 Chapter 8
To remove the alcohol wick from the alcohol cartridge:
1. Grasp the cartridge with
both hands. With the
knob in one hand and
the wick retainer cap in
the other, twist and pull
apart the assembly. 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. DO NOT
use a pencil point
because bits of lead
could break off.
3. Examine the white alcohol wick. Discard wicks that are severely
discolored or physically damaged. Some light brownish-yellow
discoloration of the wick is normal.
If the wick is in good condition, dry it by placing it on a clean
surface in a well-ventilated area and allow it to dry for 16 hours.
4. Before re-installing the alcohol wick, make certain that all parts
are clean. Small bits of the wick or debris can cause serious
problems if they get into the PortaCount 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.
