STERIS does not intend, recommend or represent in any way that the AMSCO 7052HP Single-Chamber
Washer/Disinfector and the AMSCO 7053HP Single-Chamber Washer/Disinfector be used for the terminal disinfection
or sterilization of any regulated medical device. The AMSCO 7052HP Single-Chamber Washer/ Disinfector and the
AMSCO 7053HP Single-Chamber Washer/Disinfector are intended only to perform an initial step in the processing of
soiled, reusable medical devices. If medical devices will be contacting blood or compromised tissues, such devices must
be terminally processed in accordance with device manufacturer's instructions and/or Good Hospital Practices before
each use in human patients.
Any alteration of this equipment not authorized or performed by STERIS will void the warranty. Alteration of this
equipment which could adversely affect its operation and efficacy may violate national, state and local laws or
regulations.
The protection provided by the equipment may be impaired if the equipment is used in a manner not specified by
STERIS.
To help ensure operators are adequately trained in the safe use of the equipment, STERIS recommends:
• all personnel who operate or maintain the equipment are trained in its operation and in its safe use;
• personnel working with toxic chemicals and vapors (if applicable) have comprehensive instructions in the
washer/disinfector process, relevant health hazards and methods to detect the escape of toxic materials;
• there is regular training of all personnel concerned with the operation and maintenance of the equipment;
attendance records are maintained; and that evidence of understanding is demonstrated;
• current Safety Data Sheets (SDS) should be available to all users in the department. For current SDS, contact
STERIS.
Serious incidents that have occurred in relation to this medical device should be reported to the manufacturer and
competent authority in the country where the incident occurred.

Permissible Environmental Conditions
The AMSCO 7052HP Single-Chamber Washer/Disinfector and the AMSCO 7053HP Single-Chamber Washer/
Disinfector are designed to operate under the following conditions:
• Indoor use only;
• Altitude of operation up to 2000 m (6560 ft);
• Temperature of 5 to 40°C (41 to 104°F);
• Relative humidity of 30% to 80% non-condensing;
• Pollution Degree 2.
Pollution degree 2: Equipment must be installed in an environment where normally only non-conductive pollution
occurs but where occasional, temporary conductivity caused by condensation can be expected (as determined according
to International Standard EN/IEC 61010-1, Third Edition).
Seismic Anchorage System (Accessory)
A seismic anchorage system (based on California requirements) is available for high-risk seismic zones (refer to CBC
2013 report # 10392574 and CBC 2019 report # 1186350).
Noise Level
Equivalent Sound Pressure: 60.6 dB (A). (Results determined according to ISO-3746: 2010 Third Edition Standard:
Acoustics – Determination of sound power levels and sound energy levels of noise sources using sound pressure – Survey
method using an enveloping measurement surface over a reflecting plane.)

WARNING
CHEMICAL BURN AND/OR EYE INJURY HAZARD
Chemicals are caustic and can cause adverse effects to exposed tissues. Do not get in
eyes, on skin or attempt to swallow. Read and follow the precautions and instructions
on the chemical label and in the Safety Data Sheet (SDS) prior to handling the chemical,
refilling the chemical container or servicing the chemical injection pump. Wear
appropriate Personal Protective Equipment (PPE) whenever handling the chemical or
servicing the chemical injection pump and lines.

Operator Manual AMSCO®7000 Series 10432589_G
Rack and items are extremely hot when cycle is completed. Allow rack and items to cool
to room temperature and always wear appropriate Personal Protective Equipment (PPE)
before reaching into chamber.
WARNING
SLIPPING HAZARD
To prevent slips, keep floors dry. Promptly clean up any spills or drippage. For spills or
drippage of detergents or other chemicals, follow safety precautions and handling
procedures set forth on detergent or chemical label and/or Safety Data Sheet (SDS).
CAUTION
POSSIBLE EQUIPMENT DAMAGE
Always position manifold rack over the manifold connector before operating
washer/disinfector. If manifold rack and/or bottom rotary spray arm assembly are not
positioned correctly, damage may result and washer/disinfector will be unable to
effectively wash load.
Always select a cycle appropriate for the items being processed. Failure to do so may
result in product damage.
Suction tips (as well as other items) must be fully enclosed within the accessory (curved
suction tips facing inward) to prevent obstruction in conveyor system.
Use nonabrasive cleaners when cleaning unit. Follow directions on containers and rub in
a back-and-forth motion (in same direction as surface grain). Abrasive cleaners will
damage stainless steel. Cleaners rubbed in a circular motion or applied with a wire
brush or steel wool on door and chamber assemblies can be harmful to stainless steel.
Do not use these cleaners on painted surfaces.
When choosing a detergent, select one with a low-chloride content. Detergents with a
high-chloride content must not be used, as such detergents may harm stainless steel.
Wipe all plastic surfaces or painted surfaces with 70% isopropyl alcohol cleaner (such as
glass or countertop cleaners).
