Caution!
Always place loads on the shelves provided to avoid possible
uneven heating and damage to the oven.
The two shelves are designed to be pulled out about halfway without tipping. Do not overload the
shelves. Shelf support capacity is listed in the Capacities section (1.5.2). Do not overfill the oven.
Distribute the workload evenly so airflow is not restricted. The workload should not take up
more than two-thirds of any dimension of the inside cavity.

For best results:

Do not place the load within 7.62cm (3 inches) of louvers
or within 15.25cm (6 inches) of the chamber ceiling

Stagger the load within the chamber to allow as much air
as possible to circulate from the supply side to the
return side of the oven
5.2. Pre-Startup Checklist

Read this manual carefully and make use of its instructions and explanations. Safe,
continuous, satisfactory and trouble-free operation depends primarily on your degree of
understanding of the system and your willingness to keep all parts in proper operating
condition.

Verify line voltage. Voltage must correspond to nameplate requirements of motors and
controls. Incorrect line voltage can result in serious damage. Refer to Section 1.5.4 for more
information.

Check fresh air and exhaust openings. The dampers have been designed to remain slightly
open to allow processed solvent gases to escape. Do not be careless about restrictions in and
around the fresh air and exhaust openings and stacks. Refer to Sections 1.5.2 and 4.3 for
information on exhaust specifications and requirements. Under no condition can they be
permitted to become so filled with dirt that they reduce airflow.

For drying application, open exhaust damper to prevent buildup of moisture.
