System Sanitization and Cartridge
Replacement
The frequency with which you will need to clean your unit and
replace cartridges is dependent on your feedwater’s charac-
teristics, your purity requirements and your usage. Sanitize
your EASYpure UV/UF and replace the cartridges when the
product water purity drops below acceptable levels of resistiv-
ity, when organic levels become too high, or if a new 0.2
micron filter was installed. To sanitize the EASYpure UV/UF,
the purification cartridges must be replaced with a sanitization
cartridge and the two empty cartridges supplied with your unit.
The simple-to-use sanitization cartridge is available from
Barnstead|Thermolyne (Catalog No. D50245). This is used in
addition to the empty cartridges included with this unit to effect
a complete sanitization.
1. Turn unit off.
2. Disconnect the unit from the power supply. Discon-
nect the unit from the water supply.
3. Depressurize system by opening the draw-off
valve.
4. Open the cartridge access door in the rear of the
unit by sliding the latch down and pulling the door
toward you. The door will swing down.
5. Remove the exhausted cartridge in the right-hand
position by pulling it first up and then out. Used
cartridges can be recycled; see the P.U.R.E.
information packed with your new cartridges.
6. Remove a D50245 sanitization cartridge from its
packaging. Press the upper end of the D50245
sanitization cartridge into the upper right position
until it bottoms out.
7. Lower the cartridge and insert the lower end cap
into the lower socket until it is firmly seated.
Maintenance and Servicing
Warning
Disconnect from the power supply prior
to maintenance and servicing. Refer
servicing to qualified personnel.
Warning
Depressurize system prior to opening
cartridge access door.
Note
The cartridges will still contain water
when removed. Therefore, you will
want to have a sink, bucket or other
waterproof container available to place
them in after removal.
Note
If the EASYpure UV/UF is wall
mounted, remove the power cord and
rotate the EASYpure UV/UF until the
cartridge access door faces forward
and the EASYpure UV/UF locks into
place.
Note
The two flanges on the end cap should
be able to slide down on each side of
the keyway wall.
