display will revert temporarily to set points for approximately 5
seconds.
Auto Run - Time
1. Refer to the
section for start-up.
2. To execute an Automatic time-based run, execute the
following steps:
a. Select the Run Type as “Time”.
b. Use the
Select
button and the “
+
”/ “
-
” buttons to
select and modify the Temperature, “Heat Time” and
“Run Time” parameters. The Run and Heat Time can
be set from 0.01 to 9.59 hours (Heat Time also has
“CCC” for continuous use).
c. Select a vacuum set point: Since this is a time-based
run, the vacuum will be the maximum allowed by the
attached external vacuum pump, regardless of the
vacuum pressure set point.
d. Press the
Auto Run
button to start the run. The
cover locks and the lid locked indicator is lit. The rotor
starts spinning. The run time display is counting
down in 1 minute Intervals. The heat time is counting
down if the set point is not set to “CCC” and if the
temperature set point is not set to “no” (use the
select button to view “Heat Time”). The temperature
rises in 1 °C increments to set temperature. The
vacuum is applied to the chamber and the vacuum
pressure begins decrementing down from “HPr”
(atmospheric pressure).
Note:
If the cover is not closed, the display will show
“Lid” and the run will not start.
e. Press
RL On/Off
for radiant heat. Press at any time
to turn ON and OFF. (As long as there is time left in
the heat timer and if the temperature set point is not
set to “no”).
f.
Once the time expires, the run will automatically stop,
the display will show “End”, the SAV valves will click,
also allowing air to bleed into the chamber. The unit
will sound 1 beep that will be repeated until the user
acts on it.
g. After the rotor stops spinning, the cover unlocks and
the lid locked indicator is turned off. The display
reverts to last set parameters.
h. Open the cover and remove samples.
Auto Run - Vacuum
1. Refer to the “Manual Run” section for start-up.
2. To execute an Automatic Vacuum run, execute the
following steps:
a. Select the Run Type as “Vac”
b. Use the
Select
button and the “
+
”/ “
-
” buttons to
select and modify the Temperature, “Heat Time and
“Run Time” parameters. The Run and Heat Time can
be set from 0.01 to 9.59 hours (Heat Time also has
“CCC” for continuous use).
c. Select a vacuum set point at which the run should be
terminated, ensure the attached external vacuum
pump can generate the required vacuum level
d. Press the
Auto Run
button to start the run. The
cover locks and the lid locked indicator is lit. The rotor
starts spinning. The run time display will count up in 1
minute intervals. The heat time is counting down if
the set point is not set to “CCC” and if the
temperature set point is not set to “no” (use the
Select
button to view “Heat Time”). The temperature
rises in 1 °C increments to set temperature. The
vacuum is applied to the chamber and the vacuum
pressure begins decrementing down from “HPr”
(atmospheric pressure).
Note:
If the cover is not closed, the display will show
“Lid” and the run will not start.
e. Press
RL On/Off
for applying radiant heat. Press at
any time to turn ON and OFF. (As long as the heat
timer has not expired, and if the temperature set
point is not set to “no”).
f.
Once the unit senses the set vacuum pressure in the
chamber has been achieved, the run will
automatically stop and the display will show “End”.
The valve will click, allowing air to bleed into the
chamber. The unit will sound 1 beep that will be
repeated until the user acts on it.
g. After the rotor stops spinning, the cover unlocks and
the lid locked indicator is turned off. The display
reverts to last set parameters.
h. Open the cover and remove samples.
Drying Rate
Thermal energy can be applied to the concentrator chamber
to counteract the cooling effect of evaporation, maintain the
samples in the liquid state, and accelerate the concentration
run. Select the highest drying rate if you desire accelerated
