Barnstead EASYpure LF Operation Manual And Parts List - Normal Operation

Normal Operation
1.
Press the “START” button on the front of the
EASYpure LF.
The EASYpure LF’s pump will begin to run and the Purity
meter will 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.
Water Draw Off
1.
Remove the protective cap from the filter bell.
2.
Depress the draw-off lever.
3.
When draw off is complete, lift the draw-off lever and
replace the protective cap on the filter bell.
Run and Standby Modes
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 LF has two operational modes.
In the run mode, the pump continuously recirculates water
through the cartridges. This is the mode that the unit enters
upon startup. If water will be drawn from the EASYpure LF
on a continuous basis throughout the day, it is recommend-
ed that the EASYpure LF be left in the run mode. In the run
mode, the purity meter display indicates the resistivity of
the water available for draw off.
In standby mode, the pump runs for ten minutes out of ev-
ery hour (i.e. ten minutes on, fifty minutes off). If water will
be drawn from the unit only infrequently, it is recommended
that the unit be put into standby mode. To put the unit into
standby mode, press the “STANDBY” button on the front of
the unit. The purity meter’s digital display will display “Sby”
to indicate that the unit is in standby mode.
NOTE
On initial startup, the purity meter may display
“ERR.” This is caused by air in the cell and
should be replaced by a resistivity reading al-
most immediately. If “ERR” does not go out
after the pump has run for a minute or if it
appears any time while the EASYpure LF is in
operation, refer to the Troubleshooting section
of this manual.
NOTE
For low organic applications, draw off 50 to 100
ml of water from system and discard prior to
drawing water for use.
