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

All ovens will produce smoke and odors when first heated.  The sm oke and odors
come from three sources:

1)

Surfaces that have not been heated during test such as shelves

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 300

E

F and allow the oven to remain at 300

E

F 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.  W hen heated, this moisture will be driven out and the above process
may have to be repeated. 

4-6

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.

4-7

Equipment shall be operated in accordance with original design parameters.

4-8

Personnel operating, maintaining or supervising shall be informed of the danger of
removing, or rendering ineffective, safety devices.
