FLUSH
: Manual Flush: Pressing the Flush
switch once will initiate a one minute flush of the
RO membrane and the display will show FL1.
Pressing the Flush switch twice will initiate a five
minute flush of the RO membrane. During this
five minute flush, the display will count down
FL5, FL4, FL3, etc. After the timed flush has
ended, the EASYpure R
O
D
I
will return to the
mode (“IdL”, Run or “SbY”) it was in when you
initiated the flush.
AUTOMATIC FLUSH
: In the Run and Standby
Mode, the EASYpure R
O
D
I
will initiate a one
minute automatic flush of the RO membrane
once every twenty-four hours (purity value being
displayed.)
Display (See Fig. 12)
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:

Three LEDs illuminate to provide system operational sta-
tus as follows:
•
RO System Operating:
Green LED ON - RO
Operation is ON; LED OFF - RO Flush or RO
Operation is OFF.
•
Low RO Purity:
Red LED ON - % rejection
between incoming water and product water is
lower than expected; LED OFF - % reject is
good.
•
Replace RO Prefilter:
Red LED ON - Unit has
been in service for 6 months, replace RO pre-
filter; LED OFF - replace prefilter as needed and
reset timer.

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.
