Specifications

Display
In addition to displaying the temperature compensated
(25°C) resistivity in megohms-cm, the display also indi-
cates operational modes and error indicators. The follow-
ing is what can appear on the display:
SbY Er1
rEC Er2
IdL Er3
AFL Er4
FL5 Er5
FL4
FL3
FL2
FL1
Operational Modes
Run Mode
Since not all qualities of permissible feedwater will reach
maximum resistivity after one pass through the unit’s car-
tridges (especially as the cartridges near exhaustion), the
EASYpure II UV/UF has two operational modes; Run and
Standby.
In the Run Mode, the UV lamp shines continuously and
the pump continuously recirculates water through the car-
tridges, the UV chamber and the ultrafilter. It is recom-
mended that the EASYpure II UV/UF be left in the Run
Mode during the day. In the Run Mode, the purity meter
display indicates the resistivity of the water available for
draw off. Allow the water’s resistivity to rise to the desired
purity before drawing off water.
1. From “IdL” press the START/STOP button to
start. The EASYpure UV/UF’s pump will begin
to run and display the resistivity of the water in
megohm-cm.
2. Allow the water’s resistivity to rise to the
desired purity before drawing off water.

Note
On initial start-up, the display may dis-
play “Er1”. This is caused by air
around the resistivity cell and should
soon be replaced by a resistivity read-
ing. If “Er1” does not go out after the
pump has run for a minute or if it
appears any time while the EASYpure
II UV/UF is in operation, refer to the
“Troubleshooting” section of this man-
ual.
Note
Do not place in IdL mode or turn off
the EASYpure II UV/UF unit during
non-work hours. Doing so will allow
bacterial growth or contamination of
the water in the system. As a result,
the system will require a lengthy rinse-
up period at the beginning of the work
day to achieve high-quality product
water.
