UNIT SPECIFICATIONS
These ovens are 220 – 240 voltage single-phase units. 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
at nominal voltage. The temperatures specified are determined in accordance with factory standards
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.

*As set at the factory, the oven controller software restricts the maximum operating temperature to
300°F. Contact Cascade Sciences to unlock the temperature restriction if you want to use the oven
for applications other than biomass decarboxylation running above the factory-restricted max
temperature.
The maximum unrestricted chamber temperature the oven can achieve is 350°F (177°C). Do not use
mesh bags at temperatures exceeding 240°F (115°C)!

INSTALLATION
REQUIRED AMBIENT CONDITIONS
These units are 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 unit 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, or any other device producing 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 air flows for ventilation and cooling.
6 inches (152 mm) of clearance is required on the sides.
24 inches (610 mm) of headspace clearance is required between the exhaust vent and any
overhead cover or partition.
o12 inches (305 mm) of vertical headspace clearance will suffice if the oven exhaust is
vented from the workspace through a duct or other channeling.
Do not place objects on top of the oven.
Allow at least 6 inches (152 mm) from the access port and fan vent on the back of the oven to the
nearest wall or partition. Keep the fan unobstructed at all times.

INSTALLATION
POWER SOURCE REQUIREMENTS
When selecting a location for the oven, verify each of the following requirements is satisfied.
Power Source: The power supply must meet the power requirements listed on the oven data plate
(located on the back of the unit, beneath the power feed inlet.
•These ovens are intended for a 220 – 240 volt, 50/60 Hz applications at 10 amps.
•The power source must be single (1) phase and protective earth grounded.
•The power 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 the supplied voltage varies more than 10%.
•The recommended wall circuit breakers for these units are 20 amps.
•Use a separate circuit to prevent loss of the unit due to overloading or circuit failure. The
circuit must meet or exceed the amperage requirements listed on the oven data plate.
Power Cord. The unit must be positioned so that all operators can quickly unplug the oven in the
event of an emergency.
•The unit comes provided with a 250V, 10 Amp, 2.5m (8ft) Euro CEE7/7 power cord.
•This unit is also provided with a 250V, 15A, 8ft 2in (2.5m) NEMA 6-15P power cord.
Fuses: The unit ships with two 10 Amp fuses. One in the power cord inlet and the other in an
adjacent fuse holder.

INSTALLATION
GENERAL POWER SAFETY
Your unit and its recommended accessories are designed and tested to meet strict safety
requirements. It is designed to connect to a power source using the specific power cord type
shipped with the unit.
For continued safe operation of your unit, always follow basic safety precautions including:
•Always plug the unit power cord into a protective earth grounded electrical outlet 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.
•Do not bend the power cord excessively, step on it, or place heavy objects on it.
•A damaged cord can be a shock or fire hazard. Never use a power cord if it is damaged or
altered in any way.
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.
