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 thermal cycle, 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 may 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 after it has been damaged.
•Use only approved accessories. Do not modify system components. Any alterations or
modifications to your unit 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 differ from those described in this manual, please contact your Cascade TEK dealer or
customer service representative for assistance.

INTRODUCTION
VACUUM PUMP OPTIONS
SVO-10-VC platen ovens can be ordered with one of several vacuum pump types installed inside the
oven utility cabinet. Pumps vary in evacuation flow rates and suitability for different baking or thermal
cycle 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 any pump oil
or sorbent use.
Shipping Locks: The roughing pump comes with built-in shipping locks to prevent damage during
transit. See page 24 for instructions on disengaging the locks prior to putting the oven into
operation.
Damage Caution: Many vacuum pumps can be damaged or destroyed by drawing full atmosphere
for extended periods. For example, if the pump is attempting to pump down the oven chamber while
the chamber door is open. Always consult the pump manual for the maximum allowed continuous
inlet pressure.
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 evacuated 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, right 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.
Building
System

12 | Page
INTRODUCTION
LIQUID NITROGEN
The oven requires a supply of liquid nitrogen to chill the platen shelves. When chilling, LN2 is pulsed
or flushed through the platens and expelled from the oven through a port located on the back of the
oven as gas nitrogen.
Venting from Workspace Required
Gas nitrogen (GN2) expelled from the oven must be vented away from the workspace area to prevent
nitrogen from crowding out oxygen in the room.
Supply Quality
The oven requires high purity LN2 4.8 at low pressure. The supply must deliver 24 – 50 psi of
pressure at the oven LN2in port(s). Platen chilling performance will vary based on LN2 connection
configuration and whether a single or dual supply of LN2 is being used.
Usage
Usage rates are dependent on the temperature the platen will be chilled to and the duration and
number of chilling phases. The use of well-insulated transfer lines will reduce LN2usage and improve
platen chilling performance.
Potential Hazards
See the Nitrogen Precautions on page 39 for liquid and gas nitrogen hazards information.
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 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.

RECEIVING YOUR OVEN
INSPECT THE SHIPMENT
Safe delivery becomes the responsibility of the carrier when a unit leaves the factory. Damage
sustained during transit is not covered by the manufacturing defect warranty.
When you receive your unit, inspect it for concealed loss or damage to its interior and exterior. If you
find any damage to the unit, follow the carrier’s procedure for claiming damage or loss. Save the
shipping carton until you are certain that the unit and its accessories function properly.
1. Carefully inspect the shipping carton for damage.
2. Report any damage to the carrier service that delivered the unit.
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.

INSTALLATION
REQUIRED AMBIENT CONDITIONS
These units are built for use indoors, at room temperatures between 15°C and 35°C (59°F and 95°F), at
no greater than 80% Relative Humidity (at 25°C / 77°F). The ambient temperature should not change by
2°C (3.6°F) or more during operation.
Operating outside these conditions may affect the oven temperature performance.
When selecting a location to install the unit, consider all environmental conditions that can adversely
impact its temperature performance. These include:
•Proximity to other ovens, autoclaves, and any device that produces significant radiant heat
•Heating and cooling vents or other sources of fast-moving air currents
•High-traffic areas
•Direct sunlight
REQUIRED CLEARANCES
These clearances are required to provide airflows for ventilation and cooling.
6 inches (152 mm) of clearance is required on the sides.
12 inches (305 mm) of headspace clearance is required between the top of the unit and any
overhead partitions.
Do not place objects on top of the oven.
Vacuum, backfill, liquid nitrogen, and access ports are located on the back of the oven. Leave
sufficient clearance for operators to safely access these ports.
