The two shelves are designed to be pulled out about halfway without tipping. Do not
overload the shelves (Refer to Support Capacity listed in Section 1.5.2). Distribute the
workload evenly so airflow is not restricted. Do not overfill your oven. The workload
should not take up more than two-thirds of any dimension of the inside cavity.
5.2. Pre-Startup Checklist
Warning!
Do not use flammable solvent or other flammable material in this
oven. Do not process closed containers of any substance or
liquid in this oven because they may explode under heat.
□ Know the system. Read this manual carefully. Make use of its instructions and
explanations. Safe, continuous, satisfactory, trouble-free operation depends primarily
on your degree of understanding the system and your willingness to keep all parts in
proper operating condition.
□ Check line voltage. Voltage must correspond to nameplate requirements of motors
and controls. A wrong voltage can result in serious damage. Refer to Section 1.5.4 for
more information.
□ Check fresh air and exhaust openings. Do not be careless about restrictions in and
around the fresh air and exhaust openings and stacks. Under no condition can they be
permitted to become so filled with dirt that they reduce airflow.
□ Ventilation. An exhaust opening in the rear of the unit is covered by a hat bracket. Do
not remove the hat bracket as it protects the exhaust opening from being completely
covered.
□ Helpful hints:
o For drying ovens, open vent to prevent buildup of moisture.
o For sample heating, close vent when no ventilation is required.
