Procedure A
Obtain a source of clean compressed gas, such
as Chemtronics
®
or equivalent. It must have a
long nozzle (straw) in order to reach deep into
the PortaCount Respirator Fit Tester.
 Turn the PortaCount Fit Tester off and
remove the alcohol cartridge.
 Insert the long nozzle inside the PortaCount
Fit Tester as shown. Keep the end of the
nozzle centered in the cavity and gently
push it in as far as possible.
The internal nozzle is
located just at the far end of
the cavity and cannot be
seen.
 Apply two or three bursts of
gas. This will not damage
the PortaCount Fit Tester.
Reinsert the alcohol cartridge.
Turn the PortaCount Fit Tester
on. Perform the Daily Checks. If the problem persists, try
Procedure B.
Procedure B
Use this procedure only if Procedure A fails to clear the internal
nozzle.
 Turn the PortaCount Fit Tester off and remove the alcohol
cartridge.
 Turn and hold the PortaCount Fit Tester up on end so that you
can look down into the cartridge cavity.
 Take a bottle of the alcohol used to operate the PortaCount Fit
Tester and drip 3 to 4 drops down into the cartridge cavity. Try to
keep the drops centered so they hit the bottom without touching
the sides. DO NOT use too much. One drop is enough if it all
reaches the nozzle.
 Keep the PortaCount Fit Tester in this vertical position for about
five minutes so the alcohol can soften or dissolve the blockage.
