1. Connect the unit to its required voltage.
2. The cover lock disengages, allowing the top cover to be opened.
The display lights up, showing the following default values:
Temperature: 45
°
C in RED
Run Time: 2.00 HRS. in GREEN
Vacuum Pressure: 01.0 in AMBER
3. Using the “SELECT” button and the up/down keys, set TEMPERATURE
between 45
°
C and 80
°
C, or “no”, for no heat.
4. Using the “SELECT” button and the up/down keys select and modif
“HEAT TIME” to between 0.01 and 9.59 hours or CCC (for continual
heating). When the heat timer expires, the heater will shut off, no matter
what the temperature setpoint reads (except if CCC).
5. Select Run Time: Since this a manual run no time adjustment is needed”
6. To select a VACUUM LEVEL, press “VACUUM SET” to illuminate LEVEL
and use th up/down keys to set vacuum to desired level. To select a
vacuum ramp rate, press “Vacuum Set” to illuminate RAMP and use the
up/down keys to set a ramp rate (5=highest, 1=lowest).
7. Place the sample tubes in the rotor and ensure that the load is balanced.
Secure rotor with the supplied knob. Close cover.
8. Pre-heat may be selected at this time, to warm chamber to 45
°
C.

3.3 EXAMPLE OF A MANUAL RUN
11. TIME DISPLAYS - Indicates heat timer or run timer set-points. In the
process of a run it indicates elapsed time or time left. Set from
0.01 [1 min.] to 9.59 [9 hours, 59 minutes] or “CCC” [continuous].
12. VACUUM PRESSURE DISPLAY - Displays vacuum level or ramp.
Chamber vacuum is displayed in torrs or millitorrs by shifting a decimal
point. “Hpr.” represents atmospheric pressure. No decimal point
indicates microns. Ramp can be set to five (5) adjustable levels.
NOTE - The unit will sound an audible beep, every time a button is pressed.
