Disconnect the inlet syringe first, then the outlet syringe.
9.
Connect the inlet to DI water and the outlet to a suitable drain.
10.
Flush the cleaning solution from the particle counter with DI water.
a.
Connect the liquid particle counter inlet to a source of ultra-pure deionized
water.
b.
Direct the liquid particle counter outlet to a drain suitable for the cleaning fluid.
c.
Flush the cleaning fluid from the particle counter for 3 - 5 minutes with DI water.
11.
Setup the liquid particle counter tubing and run the particle counter while checking
the DC Light level.
12.
If the DC Light remains out of the instrument’s designated specification, repeat the
cleaning process.
13.
If after further cleaning the DC Light remains outside the instrument’s designated
specification, please contact your local Particle Measuring Systems Service Center.
