0.2 Micron Filter Replacement
Replace the 0.2 micron filter whenever any of the follow-
ing conditions occur: every 30 days, the
product water flow rate is reduced or bacteria break
through. The 0.2 micron filter is shipped assembled with
a bell. To replace the 0.2 micron filter assembly:
1.
Remove the old 0.2 micron filter assembly by turn-
ing it counter-clockwise until it is free from the Luer
fitting.
2.
Remove the new 0.2 micron filter assembly from its
bag and insert it into the Luer fitting. Gently turn it
clockwise until it is fully seated in the Luer fitting.
3.
Rinse at least 10 liters of water through the filter to
drain prior to using the product water.
General Cleaning Instructions
Wipe exterior surfaces with lightly dampened cloth con-
taining mild soap solution.
System Sanitization
The frequency with which you will need to clean your
unit and replace your cartridges is dependent on your
feedwater’s characteristics, your purity requirements and
your usage. Sanitize your EASYpure LF and replace the
cartridges when the product water purity drops below ac-
ceptable levels of resistivity, when organic levels
become too high, or if a new 0.2 micron filter clogs
rapidly after installation even though the cartridges were
thoroughly rinsed before the 0.2 micron filter was
installed. To sanitize the EASYpure LF, the purification
cartridges must be replaced with a sanitization cartridge
and the two empty cartridges. The simple-to-use saniti-
zation cartridge (Catalog Number D50245) and two
empty cartridges (D7034) are available from
Barnstead|Thermolyne or your local representative.
1.
Turn the unit off.
2.
Disconnect the unit from the power supply. Discon-
nect the unit from the water supply.
NOTE
Used cartridges may be recycled. See P.U.R.E. in-
formation packed with new cartridges.
CAUTION
Do not overtighten the 0.2 micron filter assembly
onto the Luer fitting or use excessive force in seat-
ing it. The filter and/or Luer fitting can be damaged
by overtightening or excessive force.
NOTE
If a newly installed 0.2 micron filter clogs rapidly
after installation, the EASYpure LF may need to
be sanitized to remove bacterial contaminants.
See System Sanitization.
WARNING
Disconnect from the power supply prior to main-
tenance and servicing. Refer servicing to quali-
fied personnel.
Avoid splashing disinfecting solutions on clothing
or skin.
Ensure all piping connections are tight to avoid
chemical leakage.
Ensure adequate ventilation.
Carefully follow manufacturer’s safety instructions
on labels of chemical containers and material
safety data sheets.
NOTE
The cartridges will still contain water when re-
moved. Therefore, you will want to have a sink,
bucket or other waterproof container available to
place them in after removal.
