Automatic Sterilization is activated at the touchscreen interface. The controller is preconfigured
for this feature.
WARNING!
To avoid possible safety hazard, the BioFlo 415 Backflow Prevention Kit,
NBS PN M1360-5002, must be installed in the water inlet line before
performing a sterilization cycle!
Be sure to follow the instructions in Section 8.1 to properly install the kit
before proceeding to sterilization.
CAUTION!
There must be liquid in the vessel for sterilization. Never begin the
sterilization process if the vessel is empty.
CAUTION!
If Sterilization Temperature does not reach 121.5°C, make sure the
water supply pressure is not too high (max. 10 PSIG). If the pressure is
too high, the water will boil off through a relief valve during the Heat A
phase, causing the water jacket to vapor lock, with the heated regulator
acting as a blocking valve. If this happens, lower incoming water
pressure.
8.1 ESSENTIAL: Backflow Prevention Kit
As indicated in the above
WARNING
, safety requires the use of a backflow
prevention kit. To properly install the Backflow Prevention Kit:
1. The backflow prevention kit should be installed on the upstream side (closest to
utility supply) of the water pressure regulator kit (NBS PN M1273-5001) if you
purchased this kit (
see Figure 30a)
.

NOTE:
If you do not have the NBS water pressure regulator kit, read Step 2 for
reference, then move to Step 3.
