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-10-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 23 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 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,
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.

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. Use the orientation images in this chapter as a reference.
5. The unit should come with an Installation and Operation Manual, a profile programming manual,
an operator 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
This oven is built for use indoors, at room temperatures between 15°C and 40°C (59°F and 104°F), at no
greater than 80% Relative Humidity (at 25°C / 77°F).
Operating outside these conditions may adversely 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, and access ports are located on the back of the oven. Leave sufficient clearance
for operators to safely access these ports.
