0.2 Micron Filter
Replacement
Thermo Scientific
Replace the 0.2 micron final filter whenever any of the following
conditions occur: the product water flow rate is reduced or bacteria break-
through. To replace the 0.2 micron filter assembly:
1. Remove the old 0.2 micron filter assembly by turning it
counterclockwise until it is free from the dispense arm manifold.
2. Remove the new 0.2 micron filter assembly from the bag and insert it
into the dispense arm manifold. Gently turn it clockwise until it is
fully seated.
Caution Do not overtighten the 0.2 micron filter or use excessive force in
seating it. Filter can be damaged by overtightening or excessive force.
Note If a newly installed 0.2 micron filter clogs rapidly after installation,
the Nanopure may need to be cleaned to remove bacterial contaminants.
See "System Cleaning."
3. Remove the protective cap from the filter bell.
4. Rinse 1-2 liters of water through the filter to drain prior to using the
product water.
