Follow these special safety precautions. 1-1 Safety precautions (

10. Always connect a test instrument’s ground lead to

the instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead last.

1. All repairs should be done in accordance with the

procedures described in this manual. This product complies with Federal Performance Standard 21 CFR Subchapter J(DHHS).

2. Check all grounds.

3. Do not power the OVEN from a “2 - prong” AC cord.

Be sure that all of the built - in protective devices are replaced. Restore any missing protective shields.

4. When reinstalling the chassis and its assemblies,

be sure to restore all protective devices including nonmetallic control knobs and compartment covers.

5. Make sure that there are no cabinet openings

through which people --particularly children --might insert objects and contact dangerous voltages.

11. Components that are critical for safety are indicated in the circuit diagram by shading,

12. Use replacement components that have the same

ratings, especially for flame resistance and dielectric strength specifications. A replacement part that does not have the same safety characteristics as the original might create shock, fire or other hazards. NOTE: Connect the oven to a 25 A. When connecting the oven to a 16 A, make sure that circuit breaker can operate.

6. Service technicians should remove their watches

while repairing an OVEN.

7. Design Alteration Warning:

Use exact replacement parts only, i.e., only those that are specified in the drawings and parts lists of this manual. Never alter or add to the mechanical or electrical design of the OVEN. Any design changes or additions will void the manufacturer’s warranty. Always unplug the unit’s AC power cord from the AC power source before attempting to remove or reinstall any component or assembly.

13. Never touch any circuit wiring with your hand nor

with uninsulated tool during operation.

14. For your safety, wear gloves on your hands.

15. Remove the all water from water-tank and Steam

generator, before repairing the oven set.

8. Never defeat any of the B+ voltage interlocks. Do

not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly installed.

9. Some semiconductor (“solid state”) devices are

easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs). Examples include integrated circuits and field-effect transistors. Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your body by touching a known earth ground.
