1. Precaution
Follow these special safety precautions.
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.
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 specied 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.
8. Never defeat any of the B+ voltage interlocks. Do
not apply AC power to the unit (or any of its assem-
blies) unless all solid-state heat sinks are correctly
installed.
9. Some semiconductor (“solid state”) devices are
easily damaged by static electricity. Such compo-
nents are called Electrostatically Sensitive Devices
(ESDs). Examples include integrated circuits and
eld-effect transistors. Immediately before handling
any semiconductor components or assemblies,
drain the electrostatic charge from your body by
touching a known earth ground.
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.
11. Components that are critical for safety are indi-
cated in the circuit diagram by shading,
or .
12. Use replacement components that have the same
ratings, especially for flame resistance and dielec-
tric strength specications. A replacement part
that does not have the same safety characteristics
as the original might create shock, re 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.
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.
