27. For S/N’s AFS ‐ 0001 through AFS ‐ 0203, open the chamber door, and insert the chamber
drain screen in the front of the chamber. The screen is in the large plastic bag found in
the SAB. For S/N’s after AFS ‐ 0203, verify the drain screen is already installed in the
chamber. Do NOT operate the P2131 sterilizer without the chamber drain screen.
NOTE: Remove the screen by rotating and pulling the screen upwards. The screen is not
designed to be tightened. For S/N’s AFS ‐ 0001 through AFS ‐ 0203, the screen has
an outward notch on the collar. For S/N’s after AFS ‐ 0203, the drain screen has an
O ‐ ring that locks the screen into the coupling in the bottom of the chamber.
28. For S/N’s after AFS ‐ 0236, the following step can be skipped. For S/N’s AFS ‐ 0001 through
AFS ‐ 0236, first remove Back Lower Panel and black Heater Assembly Cover. Reinstall the
two Heater Flange Drain Caps at the rear of the unit by removing the caps from Tee Cap
Retainers and tightening them to the Heater Flange Tees finger tight, then only one
quarter ‐ turn with wrench. Reinstall Back Lower Panel and Heater Assembly Cover.
29. Connect the high ‐ temperature drain hose to the drain connection on the back of the SMU
and ensure the jacket drain valve is closed. Ensure the opposite end is securely anchored
to prevent hose whip in the unlikely event that pressurized steam or hot water is drained
through this hose. Ensure layout of the hose is not a tripping hazard when accessing the
sterilizer.

WARNING : Hot condensate and steam can rupture a standard garden hose. Only use the
high temperature hose provided to drain the SMU or WRS.
