The following Safety Precautions must be observed when uncrating/installing, operating or servicing this equipment.

WARNING indicates the potential for personal injury and CAUTION indicates the potential for damage to equipment. It

is important to review ALL Safety Precautions before operating or servicing the equipment.

Strictly following these Safety Precautions enhances the Customer’s ability to safely and effectively utilize the unit and

helps avoid improper maintenance methods which may damage the unit or render it unsafe. It is important to

understand that these Safety Precautions are not exhaustive; Customers are encouraged to develop their own safety

policies and procedures to enhance and complement these Safety Precautions.

1.2 Safety Precautions

WARNING

PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD

While loading manifold rack, do not place miscellaneous articles on the sides of trays.

Incorrect rack loading/overloading could lead to injury and/or damage to the equipment

or instruments.

Door can support loaded manifold rack. Do not lean on door or place overloaded

manifold rack on door.

Regularly scheduled preventive maintenance is required for safe and reliable operation

of this equipment. Contact STERIS to schedule preventive maintenance or obtain the

necessary Maintenance Manual (P764334-690) if preventive maintenance is done by the

Customer.

Repairs and adjustments to this equipment must be made only by STERIS or STERIS-

trained service personnel. Repairs and adjustments performed by unqualified personnel

or installation of unauthorized parts could cause personal injury, result in improper

equipment performance, void the warranty or result in costly damage. Contact STERIS

regarding service options.

1 — Safety Precautions

2

Operator Manual AMSCO®2532 10041925_M

WARNING

PERSONAL INJURY HAZARD

All personnel involved in the operation of this washer/disinfector should be aware that

both AutoSink cycles do not offer any disinfection. Follow appropriate processing

guidelines before using cleaned items and wear appropriate Personal Protective

Equipment (PPE) before handling.

When a malfunction or fault occurs before the Thermal Rinse phase is completed, a

safety feature prevents the door from being opened. Only supervisor or service

technicians are authorized to bypass the safety feature, after taking appropriate safety

measures.

WARNING

ELECTRIC SHOCK AND/OR BURN HAZARD

Fasteners and star washers are used to ensure protective bonding continuity. Always

reinstall any star washer which may have been removed during installation or servicing.

Placing washer/disinfector Power (ON/OFF) toggle switch in OFF position to turn off

washer/disinfector DOES NOT cut off electrical power. Lockout/Tagout building

electrical disconnect switch to cut power to washer/disinfector for maintenance or

repairs.

Repairs and adjustments to this equipment must be made only by STERIS or STERIS-

trained service personnel. Service personnel must disconnect all utilities to unit before

servicing. No one should service unit unless all utilities have been properly locked out.

Always follow local electrical codes and safety-related work practices.

10041925_M AMSCO®2532 Operator Manual

WARNING

CHEMICAL BURN AND/OR EYE INJURY HAZARD:

Chemicals are caustic and can cause adverse effects to exposed tissues. Do not allow

chemicals used in the washer/disinfector to contact eyes, skin, or do not 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.

Wear gloves and eye protection when using a chemical. Avoid contact with the eyes or

skin. If a chemical spills or splashes on you, flush the affected area with water for 15

minutes. If swallowed, DO NOT induce vomiting. Seek medical attention immediately.

WARNING

BURN HAZARD

Heating coils and debris screen in the bottom of the wash chamber are extremely hot

after cycle is completed. Always wear appropriate Personal Protective Equipment (PPE)

and allow wash chamber, heating coils and debris screen to cool before reaching into

the bottom of the wash chamber.

In case of an emergency, first stop cycle by pressing Emergency Stop pushbutton. Wait

for water flow to stop before opening door. Once door is opened, wear appropriate

Personal Protective Equipment (PPE) whenever reaching into the chamber.

When cycle is completed, wait until water flow stops before opening door and unloading

unit. Hot water/steam may escape through door opening if door is opened too soon.

When cycle is completed, wash chamber, manifold rack and items are extremely hot.

Allow load to cool and always wear appropriate Personal Protective Equipment (PPE)

before removing manifold rack and manipulating clean items.

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).

Operator Manual AMSCO®2532 10041925_M

CAUTION

POSSIBLE EQUIPMENT DAMAGE

Always select a cycle appropriate for the items being processed. Failure to do so may

result in product damage.

Before starting a cycle, ensure rotary spray arms on manifold rack are not obstructed

and rotate freely. If rotary spray arms are obstructed, equipment damage may result

and washer/disinfector will be unable to effectively wash load.

Use nonabrasive cleaners when cleaning washer/disinfector. 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.

◻Floor underneath washer/disinfector has a noncombustible and nonslip surface or is covered with a metal sheet

extending to the outer edges of the washer/disinfector.

◻Walls surrounding washer/disinfector have a noncombustible surface.

IMPORTANT: After a few weeks of operation, inspect washer/disinfector for leaks. Retighten all clamps and connections.

2.6 Chemicals and Cycles - Introduction

Maximizing the efficiency and the life of the washer/disinfector is predicated on the type of water and the cleaning

chemistries used. The corrosive effects of water (deionized, soft and hard water) and contaminants found in water

(such as hardness cations, corrosive anions, metals, etc.) can shorten the useful life of both instrumentation and

equipment.

It is also important for the cleaning chemistries utilized to have low and controlled foam to maintain the pressure in the

washer/disinfector for adequate impingement and effective rinsing.

Operator Manual AMSCO®2532 10041925_M

Cleaning chemistries used should maintain effectiveness regardless of water quality, type or the contaminants

contained in the water and they should be formulated to help prevent corrosion of instrumentation and equipment due

to the use of water in the cleaning process.

IMPORTANT: STERIS does not promote, recommend or endorse the use of any other type of chemical additives and chemicals

in the processing of articles in the AMSCO 2532 Single-Chamber Washer/Disinfector, such as alcohol rinses or liquid germicides

including sodium hypochlorite solution (bleach).

2.8 Using Other STERIS Chemicals

Other STERIS chemicals can also be used for processing loads within the washer/disinfector. Contact STERIS for more

information about chemicals available for use with the AMSCO 2532 Single-Chamber Washer/Disinfector.

IMPORTANT: STERIS does not promote, recommend or endorse the use of any other type of chemical additives and chemicals

in the processing of articles in the AMSCO 2532 Single-Chamber Washer/Disinfector, such as alcohol rinses or liquid germicides

including sodium hypochloric (bleach).

Each load is processed using a specific cycle.

Refer to Table 5-1 for more details about the cycles and the parameters within the cycles such as temperature, injection

rate, etc. Use this chart as a reference while processing cycles.
