Normal Operation; Water Draw Off; Use Of Standby Modes - Thermo Scientific EASYpure 1164 Series Operation Manual And Parts List

Normal Operation

Note
On initial start-up, the purity meter
may display "ERR". This is caused by
air in the cell and should be replaced
by a resistivity reading almost immedi-
ately. If "ERR" does not go out after
the pump has run for a minute or if it
appears any time while the EASYpure
UV/UF is in operation, refer to the
Problem Solving section of this man-
ual.
Note
For low organic and pyrogen applica-
tions, draw off 50 to 100 ml of water
from system and discard prior to draw-
ing water for each use.
Note
Do not turn off the EASYpure UV/UF
during non-work hours. Doing so will
allow bacterial growth and other con-
tamination of the water in the system.
As a result, the system will require a
lengthy rinse-up period at the begin-
ning of the work day to achieve high-
quality product water.

1. Press the START/STOP button to start. The
EASYpure UV/UFʼs pump will begin to run and
the Purity meter will display the resistivity of the
water in megohm-cm.
2. Allow the waterʼs resistivity to rise to the desired
purity before drawing off water.
3. The system should be left on during the work
day. (See use of Standby mode.)

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.
Use of Standby Mode
At the end of the work day, press the Standby switch on
the front of the EASYpure UV/UF to place the unit in
Standby mode for the night.
