Function(s) of Control or Indicator (Rear View of SMU)
ITEM CONTROL/INDICATOR FUNCTION
1. Water Level Sight Gauge
Indicates water level inside jacket. Fill to HIGH mark. A low water level
switch (separate from sight gauge and not shown in picture) will create
an alarm, abort the cycle, and de ‐ energize the heaters.
2.
Pressure Safety Valve
(PSV)
Relieves overpressure @ 40 psig to prevent potential rupture of
jacket/chamber
3. Jacket Vent Valve
Manual valve that opens the jacket to atmosphere. This valve must be
closed during normal operation. Best practice includes NOT opening
this valve after shutdown to vent steam, but allow SMU to cool and
steam to condense (this will pull a vacuum in jacket, which is OK).
4. Chamber Vent Valve
Manual valve that opens the chamber to atmosphere. This valve must
be closed during normal operation. This valve is used to relieve
pressure or vacuum (e.g., if vacuum develops in chamber from
accidently leaving door closed during cool down).
5.
Recovered Water Hose
Connection (Blue ‐
Tagged)
This hose supplies water to the jacket from the WRS.
6.
Vacuum/Exhaust Hose
Connection (White ‐
Tagged)
This hose exhausts steam/air and allows the WRS to create the vacuum
necessary for sterilizer operation.
7.
Jacket and Chamber
Manual Vent Valve
Outlets
Outlet points for the Jacket and Chamber vent valves.
WARNING : A small amount of hot condensate will collect above these
valves during operation. Slowly crack the valve to allow any hot
condensate to empty out, and keep hands away from this outlet point.
8.
Jacket Drain Hose
Connection
Hose connection draining hot water from jacket. ONLY use the high
temp hose provided to drain jacket. Ensure end of hose is secured to
prevent hose whip in the unlikely event of pressurized steam
exhausting from this hose.
WARNING : A standard garden hose could rupture, resulting in
potential burns.
9. Jacket Drain Valve
Manual valve that opens the jacket to atmosphere and allows the
jacket to drain. This valve must be closed during normal operation. Do
not open this valve with pressure on jacket.
10.
Heater Flange Drain
Caps
S/N’s AFS ‐ 0001 through AFS ‐ 0236: Used to drain heater flange tees for
transport and/or storage.
11. Multi ‐ tool
Used during the setup of the sterilizer to tighten hoses and remove
panels.
12. Tee Cap Retainer
S/N’s AFS ‐ 0001 through AFS ‐ 0236: Used to store Heater Flange Drain
Caps during Transport and/or Storage of the Sterilizer.
13. Back Lower Panel This panel prevents the user from accessing underneath the Chamber.
14. Heater Assembly Cover This cover protects the user from any potential electrical shock hazard.
