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 evacuation 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.
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.

POWER SOURCE REQUIREMENTS
When selecting a location for the oven, check that each of the following requirements is satisfied:
Power source: The power source voltage and amperage must match the power requirements listed
on the oven data plate (located on the back of the unit, above the gas inlet port):
Model AC Voltage Amperage Phase Frequency
SVO-10-VC 220 – 240 20 1 50/60 Hz
•The power source must be protective earth grounded. The source must conform to all
national and local electrical codes.
•Supplied voltage must not vary more than 10% from the data plate rating. Damage to the
oven may result if supplied voltage varies more than 10%. Use a separate circuit to prevent
loss of the unit due to overloading or circuit failure.
•The oven may be operated at 208 volts. This falls within the acceptable 10% variation from
the stated 220 – 240-volt range.
•A switch or circuit-breaker must be used in the building installation to protect against
overcurrent conditions.
oRequired circuit-breaker for the wall power source is 30 Amps.
•A dedicated separate circuit for the oven is recommended to prevent possible loss of
product due to overloading or failure of other equipment on the same circuit.
Power Feed Disconnect:
•The oven must be positioned so that all operators have access to the power feed
disconnect in case of emergencies.
•The disconnect must be in close proximity to the equipment and within easy reach of the
operator.
•The disconnect must be marked as the disconnecting device for the equipment.
Internal Circuit Breakers: These ovens come equipped with multiple internal circuit breakers.
Resetting these is a service-level procedure. The cause of the overcurrent conditions that tripped
the breakers must be identified and repaired prior to resetting.

INSTALLATION
POWER FEED WIRING
The oven comes provided with an integral 6-inch (150-mm) wire braid consisting of:
•Two 10-gauge hot wires – black
•One 10-gauge earth ground – green-yellow
The oven must be earth grounded using the protective conductor terminal (green with yellow
stripe wire). Do not remove the protective conductor (earth connection). Removing the protective
conductor will negate the oven’s protections against potentially dangerous electric shocks and
create a potential fire hazard.
LIFTING AND HANDLING
The oven is heavy. Use appropriate lifting devices that are sufficiently rated for these loads. Follow
these guidelines when lifting the oven:
•Lift the oven only from its bottom surface.
•Doors, handles, and knobs are not adequate for lifting or stabilization.
•Restrain the oven completely while lifting or transporting so it cannot tip.
•Remove all moving parts, such as shelves and trays, and lock doors in the closed position
during transfers to prevent shifting and damage.
Remove the shipping cover to expose the power
wire braid. Use a Phillips-head screwdriver.
