STANDARD FEATURES

Chemical injection pumps:• Pumps are optimized to use Prolystica® Ultra Concentratechemicals. Each ultra concentrated product is 10 times moreconcentrated than equivalent traditional product; so,
10 times less chemical is injected per cycle.

Vertical sliding power door:• Constructed of double pane tempered glass to allow
operator to view chamber interior with door closed.
• While cycle is in progress, glass door remains cool to touch.
• Door is pneumatically activated using touch screens locatedon the control panel (one each side of unit) and is equippedwith a built-in safety system.

• The Washer/Disinfector comes with one enzyme and one
detergent injection peristaltic pump which automatically add
a selected quantity of chemical from 1/40 to 2 oz/gal (0.2 to16 mL/L).

• Each door is mounted on a compressed seal that reduces
heat loss and increases heating capability.

• Pumps give flexibility to dual wash combining PUC enzyme
and PUC detergent.

• If a power failure occurs, door can be opened manually. A
door interlock feature is provided to prevent crosscontamination.

• One injection peristaltic pump is dedicated to automatically
add a selected quantity of lubricant during Thermal Rinse
phase.

Stainless-steel pump is powered by a dual-speed motor. Highpump speed provides equivalent capacity of a 7.5 hp (5.6 kW)
motor, 240 U.S. gal/min at 70 ft (910 L/min at 21.3 m) headpressure. Low pump speed provides equivalent capacity of a
2 HP (1.5 kW) motor, 90 U.S. gal/min at 25 ft (341 L/min at7.6 m) head pressure. Pump impeller is mounted directly on
motor shaft and does not require additional bearings. Pump
motor is equipped with a drip-proof frame, magnetic starter,
overload protection and sealed bearings (not requiringperiodic lubrication).

• If desired, up to two additional chemical pumps can beinstalled, giving flexibility to wash with a neutral process, analkaline process, or to vary chemical used, depending onload type.
• Pumps are positioned near chemical containers. A low-levelsensor is included to indicate when the detergent level inthe container is low, or when insufficient chemical is available
for the next cycle.
• 100’ (30 m) extension tubes are included to pump chemicals
from canisters installed in a remote location to the washer/disinfector.

Pump, spray system and all recirculating piping are ofstainless-steel construction.

Microprocessor control system is equipped with a touch
screen Customer interface. This 5.7" (145 mm) color touch
screen is mounted at eye level beside chamber door (bothsides of unit) and tilted for better visibility, allowing easy
monitoring of all wash cycles. Control system monitors andcontrols all phases of each programmed cycle.

• Chamber is of sanitary-type design (horizontal fixedsurfaces are sloped, overlapping metal sheets) for complete
drainability and to reduce hard-to-clean locations.
• Single-walled, insulated construction of chamber exterior
reduces heat loss and noise level to the work area.

The microprocessor control system features:• Rotary spray assemblies are positioned (one at top andone at bottom of chamber, each measuring 24-3/8" [620 mm]long) to reach all load surfaces. Spray assemblies are easily
removable without tools to aid in cleaning and maintenance.

• Locking program cycle parameters with access code.
• Service mode for preventive maintenance testing and tofacilitate troubleshooting.
• Built-in service diagnostic program to permit systemcalibration and verification of component operations.

• Depending on type of rack accessory in chamber, manifold
connector automatically connects to accessory at start ofeach cycle.

• Security lock-out feature that enables programs andtemperatures to be locked and unchangeable without theproper access code.

• 3-W LED light, mounted within an explosion/vapor-proofenclosure, illuminates chamber interior.

• Cycle data is stored as a protection against power
disruption.

Sump:• Constructed of #304 L stainless steel with 9.5 gal (36 L)
capacity.

• Permits operator to monitor current washer/disinfector status(including current chamber temperature and time remaining
in phase).

• Removable stainless-steel filter in chamber sumpprevents debris from entering pump and piping system.
• Heating coil (steam or electric) at the bottom of the washchamber (sump) raises and maintains water temperature up
to 180°F (82°C) during the Wash phase and up to 194°F(90°C) during the Thermal Rinse phase.

• Indicates any abnormal conditions (alarm).
• Equipped with audible warning system.
Technical Control Data:• Control system consists of two microcomputer printed circuitboards located within washer/disinfector.

CYCLE DESCRIPTION• Control system backs-up all cycle memory for up to 10 years.
If power failure occurs during cycle, control battery backup
system verifies that cycle memory is retained.

ADVISORY NOTE: STERIS does not intend, recommend orrepresent in any way that this AMSCO 5052 Single-Chamber
Washer/Disinfector be used for the terminal disinfection orsterilization of any regulated medical device. AMSCO 5052
Washers/Disinfectors are intended only to perform an initial stepin the processing of soiled, reusable medical devices. If medicaldevices contact blood or compromised tissues, such devices
must be terminally processed in accordance with good hospital
practices before each use in human patients.

• Resistive Temperature Detectors (RTDs) sense
temperature inside chamber. These signals, converted into
electrical impulses, provide accurate control inputs andreadouts throughout entire cycle. Individual temperature
calibrations can be made by a trained service technician. If
temperature sensor failure occurs, alarm sounds andmessage is printed.

Once treatment cycle is selected, washer/disinfector
automatically processes load through standard phases(additional phases are included in certain treatment cycles
depending on unit configuration) as described on Cycle Charts
and in supplied Operator Manual.

• Water level sensors monitor water level of chamber sump.
If water level sensor failure occurs, alarm sounds andmessage is printed.
Top utility connections (except drain connections) facilitate
installation. All utilities (including vent, steam, electric, waterand compressed air) are connected on the top of the washer.
Top water injection gives a secure air gap of 31-1/2" (800 mm).
Backflow preventers are not required for hot and pure water.

AMSCO 5052 Single-Chamber Washer/Disinfector enables
Customers to use Dual Wash phase combining PUC enzyme
and PUC detergent in the same filling which accelerates cycle
time and reduces water consumption.

Front service panels. Piping, valves, electrical components
and wiring are easily accessible through front access panels.
Service from side of unit is not required.

SAFETY FEATURES

System Drying. Drying system is manifolded and circulates
HEPA-filtered air through piping, accessories and chamber for
1 to 60 minutes at low temperature (180°F [82°C]), or 1 to30 minutes at high temperature (240°F [115°C]). System
includes a cold water condenser. Drying system includes a
3 hp (2.2 kW), blower and three electric heaters totalling
11.4 kW. System heats and maintains chamber to 180-240°F(82-115°C). No additional duct work is required.

Vertical chamber doors are equipped with an obstruction
sensor to detect any door obstruction. If obstruction is present,door automatically opens.
The washer/disinfector is equipped with a safety lockout
feature so a cycle cannot start unless the door is fully closed.
If the door is opened during a cycle, all utility services tochamber are shut off, and the cycle stops.
Door interlock feature is provided to prevent crosscontamination. Door interlock feature allows only one door tobe opened at a time whenever power is on. When the cycle isin process, door interlock prevents either door from being
opened. Access to the load is then restricted.

Vented or Non-Vented Configuration. If ductwork is available(Vented Configuration), chamber vapors are exhausted tobuilding exhaust system through a 3.0" (76 mm) OD ventconnection located on top of chamber. If ductwork is notavailable (Non-Vented Configuration), washer/disinfector
includes a cold water condenser which can be activated onsite. Chamber vapors are exhausted through this condenser
to facility room.

Safety stop pushbutton(s), one on the load and one on theunload side, automatically stop all unit operation when pressed.
Building electrical supply disconnect switch must be used
to shut off power to the unit before servicing.

Pure Water Rinse Supply. Washer/Disinfector is equippedwith Pure Water Stainless-Steel Supply Valve. Pure water fromfacility is sprayed over load under pump pressure for
15 seconds (adjustable from 15 seconds to 15 minutes). Up tofour Pure Water Rinse treatments can be selected per cyclewith recirculated water. Pure water can also be used for thermaldisinfection stage and is heated to 194°F (90°C) using either
steam or electric heaters.

ACCESSORIES*
Impact Printer (FD094), if provided, produces an easy-to-readprinted record of whether load was properly processed at thepreset temperature, as well as a complete list of the alarm andabort in-cycle messages. A paper out LED is included.

Drain Discharge Cool Down. This feature assures waterdrained at the end of each phase, from the chamber sump to
the building drain system, does not exceed 140°F (60°C). If thewater temperature in sump is higher than 140°F (60°C), cold
water is automatically added to reduce the temperature of thewater discharged into the building drain system.

Steam Condensate Return To Drain (FD084) allows forconnection of a steam condensate return outlet to the drain
when a steam condensate return line is not available in thebuilding. Cold water is also injected in the drain piping whencondensate return water temperature is too high. Condensate
return cool down keeps the temperature in the drain piping
below 140°F (60°C).
