vessel. If the pressure sensor is being used, the control vessel with the pressure sensor installed must be
located in the back left corner of the instrument. The ber optic probe must be placed behind the pressure line
to prevent entanglement.
• The ber optic probe should slide easily into the thermowell through the frame screw and load disc until the
probe reaches the bottom of the thermowell.
• Do not try forcing the ber optic probe.
• If probe cannot be easily inserted, check vessel alignment. Loosen the screw and realign.
CAUTION
If resistance is felt when trying to insert probe, ensure that the thermowell is not broken inside the Teon
cover. The sharp edges of any break can restrict the movement of the probe.
10. With the door open, use the Turntable Icon to rotate the turntable. Observe the positioning and balance of the
turntable. Permit the turntable to rotate 2 or 3 times to ensure that the pressure sensing line and temperature
probe do not become entangled. Make adjustments by re-seating the turntable if necessary.
Load and perform a Method
1. Verify Max Power Monitor is enabled and the alarm time is programmed for 5 minutes (Settings > Run > Max
Power Monitor).
2. Select/load the method from the Classic directory. See “Methods” section of this manual or contact CEM
Corporation if assistance is needed creating a new method.
• “Vessel Type” = “EasyPrep” or “EasyPrep Plus” (see “Vessel Components to determine the control vessel)
• See “Operating Parameters” in “Appendix B” before programming method parameters
3. Close the instrument door.
4. Select “Start” to run the method. The instrument will begin the method according to the selected parameters
– initializing, ramping, holding, cooling, etc.
4.1. Verify that vessel count, type and position are correct.
NOTE
If a run is stopped during the reaction, do not restart the method with hot vessels. Allow vessels to cool
for a minimum of 15 minutes, vent vessels and reseal, and restart method from the beginning.
