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.
