Prepare the Alcohol Cartridge
The wick must be saturated with isopropyl alcohol for the PortaCount
Fit Tester to make particle measurements. Fill the alcohol cartridge
as follows.
C A U T I O N
Isopropyl alcohol is hazardous material. DO NOT
ingest or allow alcohol to contact your eyes or skin.
Refer to the Safety Data Sheet (SDS) located in the
box of alcohol for handling precautions and first aid
procedures.
Always recap the alcohol fill capsule and other
containers immediately to prevent absorption of
moisture and the escape of alcohol vapors.
Dispose of any alcohol with visible contamination.
Any dirt or debris that gets into the PortaCount Fit
Tester can plug the small internal nozzle and prevent
operation.
DO NOT allow the black part of the alcohol
cartridge to make contact with any surface that may
be dirty. Keep the storage cap and alcohol
cartridge clean.
The alcohol cartridge is inserted into the cartridge
cavity during use. It is critically important to keep
dirt and lint out of the cartridge cavity.
Cover the cartridge cavity with the storage cap (see
Step 10) when the instrument is not being used and
when transporting the PortaCount Fit Tester.
1. Make certain the PortaCount Fit Tester is turned off.
2. Remove the alcohol cartridge from the PortaCount Fit Tester by
twisting it counter-clockwise.
