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 LF has two operational modes; Run and
Standby.
It is recommended that the EASYpure II LF be left in the
Run Mode during the day. In the Run Mode, the purity
meter display indicates the resistivity of the water avail-
able for draw off. Allow the water’s resistivity to rise to
the desired purity before drawing off water.
Standby
In Standby (“SbY”) Mode, the pump will restart for ten
minutes out of every hour (i.e 50 minutes off, 10 minutes
on), during which time the display reads “rEC” which indi-
cates recirculation. This will allow the unit to produce
high quality water quickly upon being placed in the Run
Mode. It is recommended that the EASYpure II LF be
placed in the Standby Mode during non-work hours. At
the end of the work day, press the STANDBY switch to
place the unit in Standby mode. “SbY” will appear on the
display.
Idle Mode (“IdL”)
“IdL” indicates the unit is powered and waiting to be
placed in Run or Standby Mode.
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 LF 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 LF unit during non-
work hours. Doing so will allow bacte-
rial 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.
CONTROLS AND NORMAL OPERATION
Note
If the unit is in Standby and power to
the unit is turned off or lost, the unit
will return to Standby once power is
restored.
