Safety Precautions Operator Manual 920509-645
1
The following Safety Precautions must be observed when operating and servicing this Basil®4700 Cage and
Rack Washer. WARNING indicates potential for personal injury and CAUTION indicates potential for damage to
equipment. For emphasis, certain Safety Precautions are repeated throughout the manual. It is important to
review ALL Safety Precautions before operating and servicing the unit.
WARNING – PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD:
WARNING – PERSONAL INJURY HAZARD:
WARNING – CHEMICAL BURN AND/OR EYE INJURY HAZARD:
Only STERIS or STERIS-trained service technicians should make repairs and adjustments to this
equipment. Maintenance done by inexperienced, unqualified personnel or installation of unauthorized
parts could cause personal injury, invalidate warranty or result in costly damage. Contact STERIS
regarding service options.
Regularly scheduled preventive maintenance, in addition to faithful performance of minor maintenance
described in this manual, is required for safe and reliable operation of this equipment. Contact STERIS
to schedule preventive maintenance.
To open doors from inside wash chamber, pull EMERGENCY STOP cables. Washer operation will auto-
matically stop. Then, push firmly on door panel using shoulder and upper arm, applying upper body
force.
Always wear appropriate Personal Protective Equipment (PPE) when cleaning or removing debris from
bottom of wash chamber and over suction plate.
Never perform cleaning of wash chamber until full cycle has been completed. If cycle has not been
completed, contaminated debris or water may remain in the bottom of the wash chamber.
Keep fingers away from door hinges to prevent pinching.
Items in washing cart may move during processing and be filled with residual hot water or protrude from
cart at the end of the cycle. Always wear appropriate Personal Protective Equipment (PPE) and care-
fully remove utensils and items from cart.
To prevent tipping, place biggest and heaviest items on the lower levels of accessory cart.
Washer detergents are caustic and can cause adverse effects to exposed tissues. Do not get in eyes,
on skin or attempt to swallow. Read and follow precautions and instructions on detergent label and in
Material Safety Data Sheet (MSDS) prior to handling detergent, refilling detergent container or servic-
ing detergent injection pump or lines. Wear appropriate Personal Protective Equipment (PPE) when-
ever handling detergent or servicing detergent injection pump and lines.
Wear appropriate Personal Protective Equipment (PPE) when removing clamps and replacing squeeze
tubes. Residual chemicals might remain in used squeeze tubes. If chemical contacts skin or eyes,
immediately flush with running water for at least 10 minutes. If contact was with eyes, seek medical
attention.
Wear gloves and eye protection when using a descaling product. Avoid contact with eyes or skin. If
spilled or splashed, flush with plenty of water for 15 minutes. If swallowed, DO NOT induce vomiting.
Administer an alkali with plenty of water. Seek medical attention immediately.
SAFETY PRECAUTIONS

1-2
920509-645 Operator Manual Safety Precautions
WARNING – ELECTRIC SHOCK HAZARD:
WARNING – BURN HAZARD:
WARNING – SLIPPING HAZARD:
CAUTION – POSSIBLE EQUIPMENT DAMAGE:
Disconnect all utilities to washer before servicing. Do not service washer unless all utilities have been
properly locked out. Always follow local occupational health and safety regulations, as well as electric
and plumbing codes.
Allow unit to cool down before performing any service on mechanical components and on piping. Com-
ponents and piping become very hot during operation.
Inner surfaces of washer are very hot after cycle completion. Operator should wear appropriate Per-
sonal Protective Equipment (PPE) and avoid all contact with inner walls when entering chamber to
unload washer.
Pipes may be extremely hot.
When cycle is complete, partially open chamber door and allow chamber and load to cool. Hot steam
may escape through door opening if door is fully opened after a cycle.
To prevent slips, keep floor dry. Promptly clean up any spills or condensation. If spilled liquids are deter-
gents or other chemicals, follow safety precautions and handling procedures set forth on detergent or
chemical label and/or Material Safety Data Sheet (MSDS).
Always use non-foaming chemical for effective cleaning and proper pump and water level control opera-
tion. Follow manufacturer’s recommendations for amount of chemical to be used.
Always use a silicone lubricant to lubricate squeeze tubes. Petroleum-based lubricants, such as Vase-
line®1 or grease, will cause squeeze tubes to melt.
Avoid product damage. Always select a cycle appropriate for items being processed.
Before operating unit, always position manifolded Bottle Washing Cart over central water inlet connec-
tor. If manifolded accessory is not positioned correctly, damage may result and unit will be unable to
effectively wash load.
Do not process load using Bottle Washing Cart when Automatic Floor Tilting option is activated. If Auto-
matic Floor Tilting is used, manifolded water inlet and washer will be damaged.
Remove all cellulose-type bedding from cages and pans before processing. Cellulose bedding can clog
filters and piping.

Safety Precautions Operator Manual 920509-645
CAUTION – POSSIBLE EQUIPMENT DAMAGE (Cont’d):
Tables 1-1 and 1-2 define certain symbols which may be on your Basil 4700 Cage and Rack Washer compo-
nents:
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. Clean-
ers rubbed in a circular motion applied with a wire brush or steel wool will scratch and dull 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 con-
tent can corrode stainless steel.

2.3 Chemical Additives
Specifications
The selection of chemical additives is open for customer preference;
however, in order to achieve optimal performance, the selected
chemical additives must meet as a minimum, the following specifica-
tions:
NOTE: When choosing and using chemicals, take note of the follow-
ing:
1) Follow chemical label recommendations for concentration of
chemical to use.
2) Follow chemical manufacturer's recommendations to determine
the temperature of the WASH treatment.
3) Follow chemical manufacturer's recommendations for the amount
of chemical used according to water hardness.
To achieve maximum cleaning efficiency, select chemical appropri-
ate to soil type being processed. STERIS recommends the following
chemicals:
