4 PRIOR TO PLACING THE OVEN IN SERVICE
4-1 Read instruction manual completely.
4-2 After the installation is completed, replace all covers and guards that had been
removed for installation. At no time should equipment be operated if covers or
guards are open, removed or partially closed.
4-3 Check incoming voltage against that shown on the nameplate.
4-4 Check operating current against nameplate rating.
4-5 Tighten all terminals, especially on power connections, to minimize terminal and
component failure due to poor contact. Connections should be checked periodically
for tightness and signs of overheating.
4-6 All ovens rated for temperatures above 500EF should be operated for 4 hours at
300EF to dry the insulation before heating to maximum temperature.
4-7 All ovens will produce smoke and odors when first heated. The smoke and odors
come from three sources:
1) Surfaces that were not heated during test such as shelves and pans
2) Binders that remain in the insulation
3) Moisture that has been absorbed by the insulation.
If during the initial run of the oven, the smoke and odors become objectionable, set
the temperature at 300EF and allow the oven to remain at 300EF until the smoke is
no longer generated. Increase the temperature in steps until you=ve reached the
maximum operating temperature. It may take several days of running at the
maximum operating temperature to eliminate all smoke and odors.
If the oven is not heated for an extended time period, moisture may accumulate in
the insulation. When heated, this moisture will be driven out and the above process
may have to be repeated.
4-8 Personnel operating, maintaining or supervising shall be instructed and trained in
their job functions and be required to demonstrate an understanding of the
equipment, its operation and safe operating procedures including emergency
shutdown.
4-9 Equipment shall be operated in accordance with original design parameters.
4-10 Personnel operating, maintaining or supervising shall be informed of the danger of
removing, or rendering ineffective, safety devices.
