Page 20: Required Ambient Conditions
INSTALLATION EQUIRED MBIENT ONDITIONS These units are built for use indoors at room temperatures between 15°C and 40°C (59°F and 104°F), at no greater than 80% Relative Humidity (at 25°C / 77°F). Operating outside these conditions may adversely affect the unit temperature performance. When selecting a location to install the unit, consider all environmental conditions that can impact its temperature performance. -
Page 21: Power Source Requirements
The recommended wall circuit breaker for these units are: • CVO-5: 15 amps CVO-5-2, CVO-10: 15 amps A separate circuit for the oven is recommended to prevent possible loss of product due to • overloading or failure of other equipment on the same circuit. -

Page 37: Theory Of Operation
OPERATION HEORY OF PERATION Vacuum Vacuum is supplied by an external vacuum supply (a pump or building system) connected to one of the oven vacuum ports. Vacuum levels obtained in the oven chamber are dependent on pump type and performance, valve settings, and the nature of the application or process, including the volume of materials outgassed. - Page 38 OPERATION Heating Control The oven temperature controller stores an operator-selected constant temperature setpoint. When powered, the oven heats the chamber shelves to the setpoint. 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 setpoint, it pulses power to the heating elements.

Page 48: Calibrate The Temperature Display
The device must be accurate to at least 0.1°F and should be regularly calibrated by a third party. Never use alcohol or mercury-based thermometers! Cascade Sciences CVO ovens do not normally require calibration. Should your SOP or quality program require calibrations, follow this guideline. - Page 49 USER MAINTENANCE 5. Heat up and stabilization period: The oven temperature must be stable at temperature and under vacuum in order to perform an accurate calibration. The temperature is considered stabilized when the oven chamber has operated at your • calibration temperature for at least 30 minutes with no fluctuations greater than ±0.4°F.
