RO Carbon Prefilter Replacement
Chlorine and particulates will damage your RO mem-
brane, resulting in premature membrane failure.
Therefore, your EASYpure R

uses an extruded RO
carbon prefilter combination to remove chlorine and par-
ticulates from your feedwater. The frequency with which
you will need to replace the internal RO carbon prefilter
depends on your feedwater characteristics and your daily
usage. Install the internal RO carbon prefilter as follows:
1. Turn off the EASYpure R

system and discon-
nect the feedwater.
2. Open the cartridge access door in the rear of
the unit by pushing down the door latch.
3. Remove the cartridge in the RO carbon prefilter
position 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 the new RO carbon prefilter (Cat. no.
D50246) from its plastic bag.
5. Wet the o-rings with water on both end caps.
6. Press the upper end cap into the RO carbon
prefilter position until it bottoms out. Refer to
Fig. 7 if needed.
7. Lower the cartridge and insert the lower end cap
into the lower socket until it is firmly seated.
8. Close the cartridge access door.
9. Reconnect the feedwater.
10. Reset the carbon prefilter timer. See section

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.
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.
Note
If your feedwater has large quanti-
ties of particulates, we strongly rec-
ommend installing/using a
Barnstead AY1332X3 external pre-
treatment assembly in the feedwater
line which contains a high volume 5
micron sediment cartridge along with
anti-scalant. If in doubt about your
feedwater, please contact customer
service for a W.A.T.E.R. sample test
kit.
