INTRODUCTION
Thank you for purchasing a Cascade TEK oven. We know you have many choices in today’s
competitive marketplace when it comes to constant temperature equipment. We appreciate you
choosing ours. We stand behind our products and will be here if you need us.
READ THIS MANUAL
Failure to follow the guidelines and instructions in this user manual may create a protection
impairment by disabling or interfering with the unit safety features. This can result in injury or death.
Before using the unit, read the manual in its entirety to understand how to install, operate, and
maintain the unit in a safe manner. Ensure all operators are given appropriate training before the unit
begins service.
Keep this manual available for use by all operators.
SAFETY CONSIDERATIONS AND REQUIREMENTS
Follow basic safety precautions, including all national laws, regulations, and local ordinances in your
area regarding the use of this unit. If you have any questions about local requirements, please
contact the appropriate agencies.
SOPs
Because of the range of potential applications, this unit can be used for, the operator or their
supervisors must draw up a site-specific standard operating procedure (SOP) covering each
application and associated safety guidelines. This SOP must be written and available to all operators
in a language they understand.
Intended Applications and Locations
SVO vacuum ovens are engineered for drying, curing, and baking applications under vacuum in
professional, industrial, and educational environments. The ovens are not intended for use at
hazardous or household locations.
Power
Your unit and its recommended accessories are designed and tested to meet strict safety
requirements.
•Always hardwire the unit power feed to a protective earth-grounded electrical source that
conforms to national and local electrical codes. If the unit is not grounded, parts such as
knobs and controls can conduct electricity and cause serious injury.
•Position the unit so operators can quickly and easily disconnect or uncouple the power feed
in the event of an emergency.
•Avoid damaging the power feed. Do not bend it excessively, step on it, or place heavy
objects on it. A damaged power feed can easily become a shock or fire hazard. Never use a
power feed if it has been damaged or altered in any way.
•Use only approved accessories. Do not modify system components. Any alterations or
modifications to your oven not explicitly authorized by the manufacturer can be dangerous
and will void your warranty.

ENGINEERING IMPROVEMENTS
Cascade TEK continually improves all of its products. As a result, engineering changes and
improvements are made from time to time. Therefore, some changes, modifications, and
improvements may not be covered in this manual. If your unit’s operating characteristics or
appearance differs from those described in this manual, please contact your Cascade TEK dealer or
customer service representative for assistance.

INTRODUCTION
ROUGHING VACUUM PUMP OPTIONS
The turbopump on the back of the oven operates in conjunction with a roughing pump in the oven
pump cabinet. Both pumps are installed at the factory and come plumbed to the oven vacuum
system.
Refer to the pump manufacturer manuals shipped with the oven for specifications and compatibility
with applications. Consult the manual for operating requirements and maintenance or diagnostic
issues relating directly to the pump.
Shipping Locks: The roughing pump comes with built-in shipping locks to prevent damage during
transit. See page 25 for instructions on disengaging the locks prior to putting the oven into
operation.
COMPRESSED AIR SUPPLY REQUIRED
Compressed air provides the pneumatic pressure needed to operate the automated vacuum and
gas backfill vent valves. The oven chamber cannot be evacuated or backfilled without a compressed
air supply.
Use ¼ inch OD (outside dimension) tubing to connect the supply to the ¼ inch push fitting on the back,
left side of the oven, labeled Air 70 PSI.
The oven requires 70 psi of air pressure delivered at the port to function. Never exceed 80 psi.

INTRODUCTION
GASKET CHEMICAL VULNERABILITIES
The oven comes with a Viton® gasket built into the oven door. The gasket must seal against the un-
nicked contact surface on the oven body in order for the oven chamber to hold vacuum.
The gasket is a low wear, long-duration component that is rated to 220°C and typically replaced only
during scheduled services on the oven. However, the gasket is attacked by ketones, low molecular
weight esters, and compounds containing nitros. Exposing the gasket to these may damage its
integrity and require an early replacement. The gasket is a consumable component and is not
covered under the manufacturer warranty.

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 depiction on the next page as a
reference.
5. The unit should come with an operator Installation and Operation Manual, a profile
programming guide, a user manual for the vacuum display, and a manufacturer vacuum
pump manual.
6. Verify the correct number of accessory items has been included.
7. Carefully check all packaging for accessories before discarding.
