Setting up the Model 8026 Particle Generator
The purpose of the particle generator is to supplement the naturally
occurring particles in the room environment. The N95-Companion requires a
minimum count of 70 particles/cc to operate. The target is 100 to 300
particles/cc for optimal performance.
Follow the steps below to set up the particle generator:
1.
Fill the reservoir with clean tap water to the fill line. You may use hot
water to help the salt tablet dissolve more quickly.
2. Drop one salt tablet into the reservoir. Each tablet contains 1.0 grams of
salt. Break the tablet before dropping it into the water to dissolve it
more quickly.
3. Place the temporary cover tightly on the reservoir and shake it gently to
dissolve the salt tablet.
4. Once the tablet is dissolved, remove the temporary cover and screw the
reservoir into the particle generator.
5. Place the particle generator at least five feet away from the N95-
Companion and P

Plus. Make sure the ventilation louvers
on the back and bottom of the generator are not obstructed, as this could
cause the instrument to overheat.

Do not place the particle generator on the table. The
internal vibrations in the generator will cause it to move
and eventually fall off the table.
6. Locate the power cord and connect it to the particle generator and to a
grounded wall outlet. Turn on the power to the generator. The power
switch is located next to the power cord receptacle.
You must run the particle generator in the testing room, with the door
closed, for at least 15 minutes before you begin fit testing to allow the
particle count to stabilize. You must operate the generator in an upright
position at all times, and leave it running until all fit tests for the day are
complete.
One reservoir full of salt solution will last from 8 to 16 hours, depending on
the generator setting. Refer to the
Model 8026 Particle Generator
Operations Manual for information on changing the output setting.
