Jacket
Pressure
High
Air compressed in
jacket during water
fill
RTD or RTD
transmitter failure
SMU tilt is not steep
enough
Condensate drain
screen plugged
Solid state heater
relays leaking
current
Jacket pressure
transmitter failure
Turn OFF sterilizer and allow jacket to cool and
depressurize. Open jacket vent valve to bring pressure to
zero. Close jacket vent valve. Turn sterilizer back ON.
Contact a qualified maintenance technician to inspect RTD
and RTD transmitter for physical damage, loose wires,
broken communication cable to PLC. Compare
temperature versus pressure on STATUS screen. Replace
as needed.
Shim the rear of the sterilizer higher to improve
condensate flow to the chamber drain.
Remove and clean screen. Replace after cleaning.
Contact a qualified maintenance technician to test relay for
leakage and replace as needed.
Open Chamber Door and compare digital pressure readout
on STATUS screen on PLC to analog gauge on front panel.
Jacket Pressure reading ≈ 28 psig and Chamber Pressure
Reading ≈ 0 psig.

On “CONFIRM SETUP” screen, zero barometric pressure.
This is only required during setup at a new location.
Tighten door.
Contact a qualified maintenance technician to inspect and
test both valves. Replace as needed (Note flow direction.
Arrows on valve should point toward each other (
