Routine Maintenance
Preventive Maintenance
If a building steam source is not available, the sterilizer may be equipped with
an electric steam generator. The generator automatically converts water to
steam using electric heat. The steam created is then used to power the
sterilizer.
Steam generators are highly susceptible to mineral scaling if the supplied
water has any level of hardness. Refer to
requirements.
IMPORTANT:
Regardless of the hardness level of supplied water, the
generator must be flushed every day before use to prevent mineral scaling or
carryover of debris into the chamber.
ATTENTION: Warranty on this steam generator will be voided unless daily
flushing procedures are performed.
1. Press the
ON
button on the sterilizer touch screen (screen #0). Display
advances to screen #72. Instructions on how to flush the generator are listed
on screen #72.
2. Check generator pressure gauge (see Fig. 3-1). Generator must be at
0.0 psig and room temperature before flushing.

CAUTION - POSSIBLE
EQUIPMENT DAMAGE:
Failure to flush generator
on a daily basis could re-
sult in generator malfunc-
tions. Warranty on the gen-
erator will be voided un-
less flushed daily.
WARNING - BURN HAZ-
ARD: Before daily flush-
ing of the generator,
generator must be at
0.0 psig and cooled to
room temperature.
CAUTION - POSSIBLE
EQUIPMENT DAMAGE:
Before flushing generator,
ensure generator drain
valve is fully open to pre-
vent generator heaters
from turning on during
