7.5.4 Steam Generator Flush
and Drain Set Up
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
Table 7-3 for
water quality 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.
NOTE: Warranty on this steam generator will be voided unless daily
flushing procedures are performed.
The sterilizer will automatically flush the generator. See
Section 7.5.3, Utilities Control, on page 7-16 for information on
setting the duration and start time of the automatic generator flush.
NOTE: The generator must be flushed every day before use.
