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 properly, 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 are not covered by
the manufacturing defect warranty.

INTRODUCTION
VACUUM PUMP OPTIONS
SVO-5-VC ovens can be ordered with one of several vacuum pump types installed inside the oven
utility cabinet. These pumps vary in pump down flow rates and suitability for different baking
applications.
Refer to the vacuum pump manufacturer manual included with the oven for specifications and
compatibility with applications. Consult the manual for operating requirements such as pump oil and
sorbent use.
Damage Caution: Unless explicitly designed to draw full atmosphere pressure for extended periods,
vacuum pumps can be quickly damaged or destroyed if exposed to streaming external atmosphere.
For example, if a pump is attempting to vacuum down the oven chamber and the chamber door is
open. Always consult the pump manual for the maximum allowed continuous inlet pressure.
Shipping Locks: The roughing pump comes with built-in shipping locks to prevent damage during
transit. See page 21 for instructions on disengaging the locks prior to putting the oven into operation.
COMPRESSED AIR SUPPLY REQUIRED
Compressed air provides the mechanical pressure needed to operate the automated vacuum and
gas backfill vent valves on the back of the oven. The oven chamber cannot be pumped down or auto
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.
