INTRODUCTION
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
CVO-10
The oven comes with cured silicone gaskets built into the oven door and door window. The
door gasket must seal against the un-nicked contact surface on the oven body in order for
the oven chamber to hold vacuum. It does not typically require replacement unless
damaged by being cut or nicked.
The manufacturer recommends keeping at least one spare door gasket on hand. This
allows the oven to be quickly put back into operation in if the gasket is damaged during
oven operations.
The gasket is a consumable component and not covered under the manufacturer warranty.
CVO-5s
Each oven comes with a replaceable cured silicone 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 230°C. It is vulnerable to acids and
solvents.
The chamber liner gasket is a non-warranty item subject to compression forces, heat, and
outgassed byproducts. Heavy usage rates may necessitate frequent replacements. The
manufacturer strongly recommends keeping at least one spare gasket on hand during
operation.

RECEIVING YOUR UNIT
INSPECT THE SHIPMENT
•When a unit 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. Inspect the unit for signs of damage. See the orientation depictions on the next pages as
reference.
5. Verify that the correct number of accessory items has been included.
6. The unit should come with an Installation and Operation Manual.
7. Carefully check all packaging for loose accessory items before discarding.
