UNIT SPECIFICATIONS
This oven is a 230 voltage single phase unit. Please refer to the oven data plate for individual electrical
specifications.
Technical data specified applies to units with standard equipment at an ambient temperature of 25°C and
a nominal voltage. The temperatures specified are determined in accordance with factory standard
following DIN 12880 respecting the recommended wall clearances of 10% of the height, width, and depth
of the inner chamber. All indications are average values, typical for units produced in the series. We
reserve the right to alter technical specifications at all times.

INTRODUCTION
VACUUM PUMP
The CVAC-9.3 oven requires a vacuum source. The oven does not come with a vacuum pump.
Use of an oil trap plumbed on the vacuum line between the oven and the pump is strongly
recommended. The trap protects the pump from any oils outgassed during your baking
application or procedure. This extends the life of the pump. All maintenance and instructional
information should be obtained from the pump manufacturer if it was not shipped with the pump.
Mounting studs and an electrical outlet for powering a vacuum pump are installed in the cabinet
inside the base of the oven. See the Connect to the Vacuum Supply entry in the Installation
section (page 25) for more information on plumbing.
GASKETS
The CVAC-9.3 comes with Viton door and window gaskets installed. These are rated to 220°C
and resistant to acids, but not solvents. The manufacturer also offers Buna gaskets resistant to
solvents and rated to 100°C.

RECEIVING YOUR UNIT
INSPECT THE SHIPMENT
•When a unit leaves the factory, safe delivery becomes the responsibility of the carrier.
•Damage sustained during transit is not covered by the manufacturing defect warranty.
•Save the shipping carton until you are certain that the unit and its accessories function
properly.
When you receive your unit, inspect it for concealed loss or damage to its interior and exterior. If you
find any damage to the oven, follow the carrier’s procedure for claiming damage or loss.
1. Carefully inspect the shipping carton for damage.
2. Report any damage to the carrier service that delivered the oven.
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 Installation and Operation Manual, a Profile Programming
Guide, and a Watlow EZ-Zone User Manual.
6. Verify that the correct number of accessory items has been included.
7. Carefully check all packaging for accessory items before discarding.

INSTALLATION
HARDWIRE REQUIREMENT
The oven requires permanent connect wiring (commonly known as hardwiring). Wiring to the power
source must be performed by a qualified electrical technician. All other Installation steps may be
performed by the end user.
INSTALLATION PROCEDURE CHECKLIST
For installing the unit in a new workspace location.
Pre-Installation
Check that the required ambient conditions for the unit are met, page 20.
Check that the spacing clearance requirements are met, page 20.
•Unit dimensions can be found on page 9.
Check that a suitable permanent connect electrical power supply is present, page 21.
Install the Oven in a suitable workspace location
Review the lifting and handling instructions, page 22.
Make sure the oven is level, page 23.
Install the oven in its workspace location, page 23.
•The oven may be connected to its power supply after this procedure.
Set up the Oven for use
Clean the oven chamber and shelving if needed, page 23.
Install the shelving in the oven chamber, page 24.
Connect the vacuum supply to the oven, page 25.

INSTALLATION
REQUIRED AMBIENT CONDITIONS
When selecting a location to install the oven, consider all environmental conditions that can affect
effective temperature range, uniformity, and stability of the oven. For example:
•Other ovens, autoclaves, and any device that produces significant radiant heat
•Heating and cooling ducts, or other sources of fast moving air currents
•High-traffic areas
•Direct sunlight
This oven is intended 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 the unit outside of these conditions
may adversely affect its temperature range and stability.
REQUIRED CLEARANCES
These clearances are required to provide sufficient air flows for ventilation and cooling.
•Allow at least 12 inches (300 mm) of empty space between the top and back of the oven and
any walls or partitions for unobstructed airflow and cooling.
•Allow at least 6 inches (150 mm) of ventilation on the sides.
•Do not place objects on top of the oven.
•Allow at least 6 inches (152 mm) from the fan vent on the back of the oven to the nearest
wall or partition. Keep the fan unobstructed at all times.
•A KF-25 vacuum port is located on the back of the oven for introducing probes into the
chamber or connecting to an external vacuum supply source. Leave sufficient clearance for
end-users to safely access this port if you will be using it.
