920518191_E Reliance®1227 Operator Manual
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.
WARNING
CHEMICAL BURN AND/OR EYE INJURY HAZARD
Always use non-foaming chemical for effective cleaning and proper pump and water
level sensor operation. Follow manufacturer's recommendations for amount of chemical
to be used.
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 spilled or splashed, flush with plenty of water for 15 minutes. If swallowed, DO
NOT induce vomiting. Seek medical attention immediately.
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 Reliance®1227 920518191_E
WARNING
BURN HAZARD
Allow washer/disinfector to cool down before performing any service on pump,
mechanical components or piping. Surfaces become very hot during washer/disinfector
operation.
In an emergency, first stop cycle by pressing Emergency Stop pushbutton. Wait until
water flow stops before opening door. Once door is opened, wear appropriate Personal
Protective Equipment (PPE) whenever entering the chamber to unload
washer/disinfector.
Inner surfaces of chamber and racks are very hot after cycle is completed. Allow
washer/disinfector to cool down before entering chamber. Always wear appropriate
Personal Protective Equipment (PPE), including gloves and faceshield, and avoid all
contact with inner walls when entering chamber.
When removing optional reservoir cover, always wear appropriate Personal Protective
Equipment (PPE), including gloves and faceshield, to prevent burns from water solution
splashes or steam.
CAUTION
POSSIBLE EQUIPMENT DAMAGE
Always select a cycle appropriate for the items being processed. Failure to do so may
result in product damage.
Items processed in the washer/disinfector must tolerate temperatures and chemicals
specified in this manual. Always follow instrument manufacturer recommendations for
cleaning instructions.
Keep floor or floor ramps (accessory) in front of doors clean to prevent bottom door
gasket from premature wear.
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 cabinet and chamber assemblies can be
harmful to stainless steel. Do not use these cleaners on painted surfaces.
1 — Safety Precautions
