Cartridge Replacement and Rinse Up
The frequency with which you will need to replace car-
tridges is dependent on your feedwater characteristics,
your purity requirements, and your daily usage. Replace
the cartridges when the product water purity drops below
acceptable levels of resistivity or when organic levels
become too high.
Remember, used cartridges can be recycled; see
P.U.R.E. information packed with your new cartridges.
1.
Turn off the EASYpure II UV and depressurize
system by disconnecting unit feedwater, opening
draw-off valve and allowing water to drain from
the unit until draining ceases.
2.
Open the cartridge access door by pushing back
the door latch.
3.
Remove the cartridge in the pretreatment posi-
tion by pulling the cartridge straight up until the
upper socket is in the keyhole of the keyway.
Next pull the cartridge straight out.
4.
Remove a new Pretreatment cartridge (Catalog
No. D50230 or D50231) from its plastic bag.
5.
Wet the o-rings on both ends.

Warning
Disconnect from the power supply
prior to maintenance and servicing.
Warning
Refer servicing to qualified personnel.
Do not disassemble water lines or re-
move cartridges where spilled water
could contact equipment that requires
electrical service. Electrical shock
hazard could result.
Warning
Depressurize system prior to opening
cartridge access door.
Note
For more demanding applications
where low TOC water is required,
allow the water to recirculate past the
UV lamp for at least an hour before
drawing off product water after chang-
ing the cartridges.
Note
The two flanges on the end cap
should be able to slide down on each
side of the keyway wall.
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.
