The two shelves are designed to be pulled out about half way without tipping for loading
and unloading. The support capacity of the shelves is listed in the Capacities Table in
the Specifications section in this manual. Do not overload the shelves.
Distribute the workload evenly so that 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.
Pre-Startup Checklist
Know the system. Read this manual carefully. Make use of its instructions and
explanations. Safe, continuous, satisfactory, trouble-free operation depends
primarily on your 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. Refer to the section on power connections in the
INTRODUCTION of this manual.
Fresh air and exhaust. Do not be careless about restrictions in and around the
fresh air and exhaust openings and stacks. Under no condition permit them to
become so filled with dirt that they appreciably reduce the air quantity. The
proper ventilation clearances should be fulfilled at all times. Refer to the Set-up
instructions in this manual.
Ventilation There is an exhaust opening in the rear of the unit that is covered by
a hat bracket. Do not remove the hat bracket as it protects the exhaust opening
from being completely covered.
Helpful hints
For drying ovens, open vent to prevent buildup of moisture.
For sample heating, close the vent when no ventilation is required.
WARNING:
Do not use flammable solvent or flammable material in this oven. Do not process
closed containers of any substance or liquid in this oven because they may explode
under heat.
