STANDARD FEATURES

Microprocessor control system is equipped with a touch
screen Customer interface. This 5.7'' (115 mm) color touch
screen is mounted at eye level above chamber on load side,
allowing easy monitoring of all wash cycles. Control systemmonitors and controls all phases of each programmed cycle.
Control system includes four factory pre-programmed andvalidated cycles (Instruments, Utensils, AutoSink Instruments
and AutoSink Utensils). Nine additional washing cycles may
be programmed to meet extra Customer requirements.

Manual drop-down doors are constructed of double panetempered glass to allow operator to view chamber interior
with doors closed. Interior glass is 1/4" (6 mm) thick andexterior glass is approximately 1/8" (3 mm) thick. Doors remaincool to touch while cycle is in progress. Each door is mounted
on a compressed seal that reduces heat loss and increases
heating capability.
Stainless-steel pump provides circulation using a 3 HP
(2.2 kW) motor with up to 22 psig (151 kPa) at pump outlet.
Pump motor is equipped with overload protection and sealed
bearings (requiring no periodic lubrication).

• Locking program cycle parameters with access code.

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

• Built-in service diagnostic program to permit systemcalibration and verification of component operations.

Unit drains between rinses to minimize residue remaining on
instruments. To help prevent bacterial contamination, unit
drains completely between cycles.

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

Manifold racks are equipped with rotary spray arms
positioned to reach all load surfaces. Removable end-tipsensure easy spray arm cleaning and maintenance.

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

The microprocessor control system features:• Service mode for preventive maintenance testing and to
facilitate troubleshooting.

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

Electric heating element (three 4 kW, 12 kW total) in bottomof chamber (sump) raise and maintain water temperature up
to 180°F (82°C) during Wash cycle and up to 194°F (90°C)
during Thermal Rinse cycle.

• Indicates any abnormal conditions (alarm).
• Equipped with audible warning system.

Removable stainless-steel filter in chamber sump preventsdebris from entering pump.

Removable front service panels provide easy access to all
piping, valves, electrical components and wiring. Servicing
from sides of unit is not required.

Wash chamber is constructed of argon-welded 20-gauge,#304 L, stainless steel (No. 4 finish). Chamber inhibits
corrosive action of detergent, and is easy to clean, with noenameled surfaces to chip or crack should an object be
accidentally dropped in chamber.

A vented unit is supplied. Chamber vapors are exhausted
to the building exhaust system through a 4.0" (102 mm) OD
vent connection located on top of washer.

Chemical injection pumps (three) are located in lower
portion of washer/disinfector. Pumps allow use of Prolystica®
2X Concentrate cleaning products. Each concentrated
product is two times the concentration of a traditional product,
therefore two times less chemical is injected to properly
process cycles.

Drain discharge cool down ensures water drained at endof each phase, from chamber sump to building drain system,
does not exceed 140°F (60°C). If water temperature in sumpis higher than 140°F (60°C), cold water is automatically added
to reduce water temperature discharged into building drainsystem.

Peristaltic pumps automatically add 1/8 to 2 oz/gal (1.0 to16 mL/L) of regular chemicals to chamber. Pumps give
flexibility to wash cycle with a neutral process, an enzyme
process, a dual alkaline/enzyme and enzyme/neutralizer
process or to vary chemical used depending upon load. Onepump is dedicated to lubricant to be injected during Thermal
Rinse phase.

Electrical control box is fan cooled to extend components
life expectancy.
Language package is supplied in English, German, Spanish,French or Italian as requested: incorporating display
messages, printouts, manuals and instructions. Otherlanguages may be available on request.
Resistive Temperature Devices (RTD) sense temperatureinside chamber. These signals, converted into electricalimpulses, provide accurate control inputs and readouts
throughout entire program. Individual temperature
calibrations can be made by a trained service technician.

A low-level sensor is included to indicate when container
detergent level is low or when insufficient chemical is available
for next cycle.
Control monitors volume of chemicals injected and indicates
if this parameter meets specified criteria during all specificphases.

Pressure switches are used to monitor chamber sump waterlevel. If pressure switch and/or temperature sensor failure
occurs, alarm sounds and message is printed.

High-capacity air blower delivers heated (240°F [116°C])
fresh air through unit piping and manifold rack to promotecomplete drying. Fresh air is drawn through a HEPA filter.

2CYCLE DESCRIPTION

If unit is recessed through one or two barrier walls, stainlesssteel barrier flanges are included to provide a finished wall
appearance. Barrier wall flange for soiled side is available asan accessory.

ADVISORY NOTE: STERIS does not intend, recommend orrepresent in any way that this AMSCO 2532 Single-Chamber
Washer/Disinfector be used for the terminal disinfection or
sterilization of any regulated medical device. These Washer/Disinfectors are intended only to perform an initial step in thereprocessing of soiled, reusable medical devices. If medical
devices contact blood or compromised tissues, such devices
must be terminally reprocessed in accordance with current
good hospital practices before each use in human patients.

Top utility connections facilitate installation. All utilities(except drain connections) are connected at top of unit.

OPTIONAL FEATURES
Non-Vented Unit is equipped with a cold water condenser.
Vapor is exhausted through this condenser to room
eliminating need for unit venting.

Items to be cleaned are placed on appropriate accessory
manifold rack and pushed into chamber, automatically couplingwith manifold solution transfer system. Operator closes door.
Once a program is selected and START is pressed, unit
proceeds through treatment schedule and automatically shuts
off at cycle completion. A display message and audible alarmindicate load is ready to be removed.

Impact Printer, if provided, produces an easy-to-read printed
record of whether load was properly processed at the preset
temperature, as well as a complete list of the alarm and abort
in-cycle messages.

ACCESSORIESInstruments and Utensils cycles (developed and validated toprovide a total cleaning solution by pairing advanced washingtechnology with Prolystica 2X Concentrate cleaningproducts) phases are as follows:

Seismic anchorage system includes a seismic report for
proper installing and securing of washer/disinfector to thebuilding floor. Washer/disinfector is designed to comply with
Seismic Zone 3 and 4 requirements.

• Pre-Wash – Cold water enters sump from building supply.
Once sump fills, pre-wash water is recirculated andsprayed over load for selected time interval. At phasecompletion, water is sent to drain.
