Page 37: Theory Of Operation
OPERATION HEORY OF PERATION The CVAC-9.3 is intended for use in closed cycle under vacuum applications such as drying. Vacuum Vacuum is supplied to the oven chamber by a vacuum pump or building system. The vacuum supply is connected to one of two vacuum fittings on the oven: A KF-25 fitting on the back of the oven or a KF-25 fitting located inside the vacuum plumbing cabinet and controlled by the Vac valve control on the front of the oven. - Page 38 OPERATION Heating Control The oven temperature controller stores a user-selected constant temperature set point. When powered, the oven heats the chamber shelves to the set point. The controller board is wired to a solid-state temperature probe located in the chamber on the rear wall. When the controller detects that the shelf temperature has dropped below the temperature set point, it pulses power to the heating elements.

Page 43: Set The Constant Temperature Set Point
OPERATION Note: When putting the oven into operation in a new location, set the constant temperature set point equal to your application or the highest temperature of your multi-step heating profile. Note: An active profile overrides the constant temperature set point. The constant temperature set point cannot be adjusted while a heating profile is active. -

OPERATION ET THE EMPERATURE IMIT This procedure sets the Over Temperature Limit heating cutoff to approximately 10˚C above the current temperature set point. If you will be running a heating profile run the oven at the highest temperature of the profile when setting the over temperature limit. Otherwise, set the oven to the steady state temperature set point of your application. - Page 45 OPERATION OTL Activation During Normal Operations Possible causes: A user has set the Over Temperature Limit below the current set point for either an active • heating profile or single constant-temperature set point.

Page 49: Calibrate The Temperature Display
The device must be accurate to at least 0.1°C and should be regularly calibrated by a third party. Never use alcohol or mercury based thermometers. Cascade Sciences vacuum ovens do not normally require calibration. Should your SOP or quality program require calibrations, follow this guideline. - Page 50 USER MAINTENANCE 5. Stability: The oven temperature must be stable in order to perform an accurate calibration. The temperature is considered stabilized when the oven chamber has operated under • vacuum at your calibration temperature for at least 1 hour with no fluctuations greater than the specified stability of the oven (see page 9).
- Page 51 USER MAINTENANCE Calibration Continued Place the controller display in the Operations menu. a. Press and hold both the Up and Down arrow buttons simultaneously for approximately 3 seconds. b. Release the buttons when “A1” appears on the top display line and “oPEr” appears in the mid display Operations Menu line.
- Page 52 USER MAINTENANCE Calibration Continued Reference Device Once the chamber has stabilized, compare the reference temperature device and oven temperature display readings. a. If the readings are the same or the difference between the two falls within the acceptable range of your protocol, the display is accurately showing the chamber temperature.
