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 1.5.3). 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.
For units where the controls are on the bottom, avoid spilling on the heater elements or oven floor
when loading the oven. Do not place the load on the oven floor plate. Placing the load on the
oven floor may cause the load to heat unevenly and the weight may cause shorting out of the
heater elements. Use the shelves provided.
Caution!
Always place loads on the shelves provided to avoid possible
uneven heating and damage to the oven.
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. Refer to the Set-up instructions (4.2.2) for
more information.
□ Ventilation. An exhaust opening resides in the rear of the unit.
□ Helpful hints:
 For drying ovens, open vent to prevent buildup of moisture

The exhaust vent may have to be closed to reach the maximum
temperature of 204°C, especially if operating on 208 volts. The
exhaust vent may need to be opened to operate properly at the
lower range of the oven's design.
