Safety Precautions
1.1 Safety Precautions — Introduction
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
Before working on conveyor pneumatic cylinders, press washer Emergency Stop
pushbutton to depressurize conveyor line. If washer is not equipped with an Emergency
Stop pushbutton, put control system power ON/OFF switch to OFF.
Conveyors are never turned OFF unless conveyor power supply ON/OFF switch or
building circuit breaker is in OFF position. Keep hands/fingers away from working
conveyors.
Do not remove rack before unloading sequence is completed. Pulling rack out of wash
chamber too soon will cause jam and may result in personal injury. Wait until washer
door starts to close and rack is stopped at final position before removing rack.
Do not stand, climb or sit on SCS conveyors.
Entanglement hazard around rollers. Keep hands, loose clothing and long hair away
from rollers.
In case of an emergency situation involving conveyors, depressurize conveyor line by
pressing pneumatic pressure-release pushbutton on any conveyor equipped with a
pneumatic cylinder. If no pressure-release pushbutton is installed, depressurize
conveyor line by pressing Emergency Stop pushbutton on washer. If washer is not
equipped with an Emergency Stop pushbutton, put control system power ON/OFF
switch to OFF.

Maximum operating weight, including weight of rack and load, is 61 kg [135 lb] for SCS
conveyors and 73 kg [160 lb] for SCS-L conveyors.
Only STERIS or STERIS-trained service personnel should assemble and/or make
adjustments to this equipment. Assembly or adjustments done by inexperienced,
unqualified personnel could cause personal injury or result in costly damage.
Regularly scheduled preventive maintenance is required for the safe and reliable
operation of this equipment. Contact STERIS to schedule preventive maintenance, or
obtain the necessary maintenance manual if preventive maintenance is done by the
Customer.
When loading an AMSCO Series basket on conveyors, ensure basket support hook is in
closed position; i.e., flush with side of basket.
WARNING
PERSONAL INJURY HAZARD
Jewelry or other metal objects may trigger conveyor sensors causing unexpected roller
or pneumatic cylinder movement.
Racks and content are heavy. If a conveyor line obstruction requires the removal of a
rack, first empty all contents from rack carefully.
Risk of crushing or pinching fingers or hands. Keep hands away from any moving part or
racks. Racks, rollers and pneumatic cylinders can start in motion at any time during
operation.
Risk of pinch point between door and threshold when the door opens. Keep fingers
away from threshold.
Risk of pinch point between door and upper panel. Do not push on top portion of doors;
do not push on door when door is rising; do not push on door when door is jammed.
When rack is present on load or unload table, keep fingers and hands away from wash
chamber door and moving rack.
1 — Safety Precautions
3
Operator Manual SCS Conveyor System P920506634_F
When opening or closing lift gate conveyor, keep hands on handle and away from any
moving parts. Positioning hand/fingers at pinch point could lead to serious personal
injury.
WARNING
ELECTRIC SHOCK AND/OR BURN HAZARD
Disconnect all utilities to unit before servicing. Do not service unit unless all utilities
have been properly locked out. Always follow local electrical codes and safety-related
work practices.
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.
Pressing conveyor line pneumatic pressure-release pushbutton or washer Emergency
Stop pushbutton only cuts pneumatic air supply to conveyor system. To cut electrical
supply, put each conveyor power supply ON/OFF switch in OFF position.
Spraying conveyors with water or detergent solutions can cause risks of electrical shock
and damage to conveyor components. Wipe clean using a small quantity of solution
applied to a sponge or cloth and dry with a lint-free cloth.
WARNING
SLIPPING HAZARD
To prevent slips, keep floors dry. Promptly cleanup any spills or drippage. If spills or
drippage are detergents or other chemicals, follow safety precautions and handling
procedures set forth on detergent or chemical label and/or Safety Data Sheet (SDS).
1 — Safety Precautions

P920506634_F SCS Conveyor System Operator Manual
CAUTION
POSSIBLE EQUIPMENT DAMAGE
Do not hit washer door with rack. Leave sufficient space to allow washer door to open
and close freely.
Do not leave or place rack in straddling position between two conveyors as this will
cause a jam. If motorized conveyor sensor detects rack edge but rack cannot be
transported to next conveyor, motorized rollers will keep turning and be damaged from
friction.
Do not use racks with a base warped by more than 3 mm [1/8"] in any direction.
Warped racks could damage sensors and cause obstructions on conveyor line.
Use non-abrasive 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 can be harmful to stainless steel. Do not use these cleaners on
painted surfaces.
Wipe all plastic or painted surfaces with a soft cloth dampened with 70% isopropyl
alcohol or any non-abrasive household cleaner (such as glass or countertop cleaners).
