Operation
1. Check feedwater and drain connections as
described in “Water Service Connections” in
the Installation section of this manual.
2. Turn main power on at power entry module.
3. Press the “START/STOP” button on the front of
the EASYpure R
O
D
I
. The EASYpure R
O

I
ʼs
pump will begin to run and the purity meter will
initially display “10.0” followed by the number
indicating the resistivity (temperature compen-
sated to 25°C) of the water in megohm-cm. As
needed the RO system will automatically oper-
ate to fill the reservoir.
4. Allow the waterʼs resistivity to rise to the
desired purity before drawing off water.
Dispensing Water from Unit
1. Remove the protective cap from the filter bell.
2. Place a container under the draw-off valve.
3. Depress the draw-off valve lever.
4. When draw off is complete, lift the draw-off valve
lever and replace the protective cap on the filter
bell.
Reservoir Replenishment
As water is drawn off from the EASYpure R

. The
reservoir will be automatically refilled in either the Run
Mode or the Standby Mode by the self contained RO sys-
tem. The water level in the tank can be determined by
using the sight gauge (See Fig. 9). If the water level is
below the low float position in the reservoir, “Add” will be
displayed and the DI operation will be turned OFF to pre-
vent air from entering the DI cartridges. Once the water
level fills up past the low float, the DI operation will
resume per the mode the unit is in.
Normal Operation
Note
If “Add” is displayed, the water level
in the reservoir is below the low
float. To prevent air from getting into
the DI cartridges, the DI operation
will be turned off until the RO opera-
tion fills the reservoir up past the low
float.
Note
When the RO operation is automati-
cally turned on, only RO water that
is above the specified % rejection
setting (factory set to 75%) will be
put into the tank. Anytime the RO
purity falls below the % rejection set-
ting the water will be diverted away
from the tank and sent to drain.
Note
Each time the RO system automati-
cally turns ON, in Run or Standby
mode, the RO membrane will be
flush water to the drain for 30 sec-
onds prior to filling the tank.

Note
For critical applications, draw 50 to
100 ml of water from system and dis-
card prior to drawing water for
each
use.
