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 the degree of your understanding of 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.
Helpful hints
For drying ovens, open vent to prevent buildup of moisture.
For sample heating, close the vent when no ventilation is required.
Startup
For fastest oven heat-up time, close the fresh-air vent. After the desired temperature is
reached, the vent may be adjusted as needed.
