BEING Scientific Inc.
BOF Mechanical Convection Oven Operating Instructions 15
Our ovens are constructed for maximum operator safety when used under standard operating conditions and
when recommended instructions are followed in the maintenance and operation of the machine.
All personnel engaged in the use of the oven should become familiar with its operation as described in these
operating instructions.
Proper operation of the unit promotes safety for the operator and all workers in its vicinity.
Each individual must take responsibility for observing the prescribed safety rules as outlined. All caution,
warning and danger labels must be observed and obeyed. All actual or potential danger areas must be
reported to your immediate supervisor.
1.6 Responsibility
1.6.1 General Responsibility
No matter who you are, safety is important. Owners, operators, and maintenance personnel must
realize that safety is a vital part of their jobs every day.
If your primary concern is loss of productivity, remember that production is always affected negatively
following an accident. The following are some of the ways that accidents can affect your production:
• Loss of a skilled operator (temporarily or permanently)
• Breakdown of lab morale
• Costly damage to equipment and laboratory samples
• Downtime
An effective safety program is responsible and economically sound.
Organize a safety committee or group and hold regular meetings. Promote this group from the
management level. The safety program can be continually reviewed, maintained, and improved through
this group. Keep minutes or a record of the meetings.
Hold daily equipment inspections in addition to regular maintenance checks. You will keep your
equipment safe for production and exhibit your commitment to safety.
Please read and use these operating instructions as a guide to equipment safety. These instructions
contain safety warnings throughout, specific to each function and point of operation.
1.6.2 Operator Responsibility
The operator’s responsibility does not end with efficient experimentation and production. The operator
usually has the most daily contact with the equipment and intimately knows its capabilities and limitations.
Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or through a
casual attitude toward laboratory equipment formed over a period of months or years. Your employer
probably has established a set of safety rules in your workplace. Those rules, these operating instructions,
or any other safety information will not keep you from being injured while operating your equipment.
Learn and always use safe operation. Cooperate with co-workers to promote safe practices. Immediately
report any potentially dangerous situation to your supervisor or appropriate person.

BEING Scientific Inc. BOF Mechanical Convection Oven Operating Instructions
16

• Before you start the portable drying/conveying system check the following:
Remove all tools from the oven.
Be sure no objects, samples or chemicals are laying on the oven.
• If your oven has been inoperative or unattended, check all settings before starting the unit.
• At the beginning of your shift and after breaks, verify that the oven is functioning properly.
• Report the following occurrences IMMEDIATELY:
unsafe operation or condition
unusual oven action
leakage
improper maintenance
• DO NOT wear loose clothing or jewelry, which can be caught while working on the equipment. In
addition, cover or tie back long hair.
• Clean the equipment and surrounding area DAILY, and inspect the machine for loose, missing or
broken parts.
• Shut off power to the oven when it is not in use. Turn the power switch to the OFF position, or
unplug it from the power source.
1.6.3 Maintenance Responsibility
Proper maintenance is essential to safety. If you are a maintenance worker, you must make safety a
priority to effectively repair and maintain equipment.
Before removing, adjusting, or replacing parts on this oven, remember to turn off all electric supplies
and all accessory equipment at the machine, and disconnect and lockout electrical power. Attach
warning tags where possible.
Be sure the oven is correctly connected to an earth grounded electrical outlet that
complies with current codes.
When you have completed the repair or maintenance procedure, check your work, and remove your tools.
DO NOT restore power to the oven until all persons are clear of the area. BEFORE you turn the oven
over to the operator for production, verify the unit is functioning properly.
1.6.4 Reporting a Safety Defect
If you believe that your oven has a defect that could cause injury, you should immediately discontinue
its use and inform BEING Scientific or your local authorized distributor.
The principle factors that can result in injury are failure to follow proper operating procedures
(i.e. lockout/tag out), or failure to maintain a clean and safe working environment.

BEING Scientific Inc.
BOF Mechanical Convection Oven Operating Instructions 17
The BEING BOF Series mechanical (forced air) convection ovens are engineered for heavy workloads and
continuous, 24-hour operation in a wide variety of chemistry, clinical, light industrial, pharmaceutical, and
research laboratory applications, such as.
• Age testing of electronic components and devices, AKA product age acceleration
• Annealing
• ASTM testing
• Baking
• Conditioning
• Curing
• Dehydrating
• Die-bonding
• Dry sterilization
• Evaporation
• Drying - glassware and part
• Heat treating
• Heated storage
• Life cycle testing
• Moisture and stability tests
• Polymerization
• Pre-heating
The mirror-finish 304 stainless steel chamber provides a strong, corrosion-resistant, inert, and easy-to-
clean environment and prevents sample contamination for any application. The wire shelves provide
maximum air circulation for uniform heating. Their design prevents shelf-tilting and sample spillage. The
wire’s surface tension minimizes or eliminates sample- or part-slide.
The microprocessor-based PID temperature controller and 3-speed, forced convection heating system
provide uniform temperature regulation without overshoot, eliminating potential sample damage. The
controller provides for the programming and storage of fixed-value and multi-segment programs. (See
Section 4.0 for controller programming.)
The adjustable exhaust allows the user to control chamber temperature uniformity by allowing humidity
to escape.
System risks, like voltage spikes, short circuits, over temperature, etc., are monitored by a safety system
that runs independently of the performance controller. Audible and visual alarms are set off, and the oven
will shut down if a risk is identified.
The BOF Series ovens have a USB communications port for data logging. (See Section 5.0 for extracting
data information.)
