Building
INTRODUCTION
Vacuum Supply
VACUUM SUPPLY REQUIRED
CVO ovens require a vacuum supply source, which must be purchased separately from
the oven. Please see the Cascade Sciences website for pumps and vacuum system
accessories suitable for your application.
cascadesciences.com/vacuum-pumps
GASKETS
Gaskets are high-wear items, subject to compression forces, heat, and outgassed
byproducts. Keeping a spare gasket on hand during operations is strongly recommended.
Each CVO oven comes with a replaceable Buna silicon gasket installed on the chamber
liner. This gasket seals against the chamber door to maintain the vacuum integrity of the
chamber. The gasket must be replaced periodically and is rated to 221°F (105°C). It is
resistant to solvents but not acids.

RECEIVING YOUR OVEN
INSPECT THE SHIPMENT
• When an oven leaves the factory, safe delivery becomes the responsibility of the carrier.
• Damage sustained during transit is not covered by the manufacturing defect warranty.
• Save the shipping carton until you are certain that the unit and its accessories function
properly.
When you receive your unit, inspect it for concealed loss or damage to its interior and exterior. If you
find any damage to the oven, follow the carrier’s procedure for claiming damage or loss.
1. Carefully inspect the shipping carton for damage.
2. Report any damage to the carrier service that delivered the oven.
3. If the carton is not damaged, open the carton and remove the contents.
4. Verify that the correct number of accessory items have been included.
5. The unit should come with an Installation and Operation Manual.
6. Carefully check all packaging for loose accessory items before discarding.
