Error Code Guide
Self-diagnostics
SM series sterilizers feature self-diagnostic circuitry to monitor operation. In the event of a malfunction, a
flashing error code appears on the display and an alert sounds. Power to the heater is also disabled. Confirm
the error code and turn off the main power switch immediately.
A safety valve activates when pressure inside the chamber is determined to be abnormal. No alert is emitted
in this case. A significant amount of steam, however, will discharge from the rear vents and other exterior
openings. When this happens, there may be an air purge problem or the temperature controller may be faulty.
Press “ENTER” immediately to terminate operation and turn off the main power switch when steam emission
settles.

What to do in the event of a power failure
When the main power switch is accidentally turned off, or when power is temporally interrupted
during operation:
1
.
SM sterilzier will remain in the same state it was in when disabled. If chamber was under pressure
at the time of the failure, it will remain pressurized.
2
.
When power is restored the operation program is lost and the solenoid exhaust valve remains
closed until chamber temperature drops below the boiling point.
Do not open the chamber at this point. Otherwise hot, pressurized steam will discharge rapidly,
possibly resulting in burns or other injury.
If opening unit becomes necessary, push the pressure relief switch to reduce chamber pressure to “0”
psi before proceeding to open.
