SAFETY PRECAUTIONS		1

The following Safety Precautions must be observed when operating and servicing this Basil® 3500 Cage and Bottle 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:

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.

WARNING – ELECTRIC SHOCK HAZARD:

Always set building electrical-supply disconnect switch and console master power switch to OFF before performing any preventive maintenance functions within compartments. Electrical shock can cause serious injury.

WARNING – BURN HAZARD:

Before performing any service on unit, wait until chamber and piping cool to room temperature.

Do not reach into sump.

Pipes may be extremely hot.

Water discharge may be extremely hot.

Wear appropriate Personal Protective Equipment (PPE) including gloves and face protection, open door slowly, and allow chamber and load to cool when cycle is complete. Hot steam may escape through door opening if door is fully opened after cycle is complete.

WARNING – SLIPPING HAZARD:

To prevent slips, keep floor dry. Promptly clean up any spills or condensation. If spilled liquids are detergents or other chemicals. follow safety precautions and handling procedures set forth on detergent or chemical label and/or Material Safety Data Sheet (MSDS).

1-1

Safety Precautions

Operator Manual

122998-741

WARNING – CHEMICAL BURN HAZARD:

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 servicing detergent injection pump or lines.

•Wear appropriate Personal Protective Equipment (PPE) whenever handling detergent or servicing detergent injection pump and lines.

Wear appropriate Personal Protective Equipment (PPE) including gloves and eye protection when using a descaling product. Avoid contact with eyes or skin. If chemical product was swallowed or in contact with eyes or skin, read and follow precautions and instructions on detergent label and in Material Safety Data Sheet (MSDS) and seek medical attention immediately.

CAUTION – POSSIBLE EQUIPMENT DAMAGE:

Always use a silicone lubricant to lubricate squeeze tubes. Petroleum based lubricants, such as Vaseline1 or grease, will cause squeeze tubes to melt.

Failure to connect wires to proper terminals may result in damage to, or malfunctioning of, unit when power is applied.

Never use rinse-dry chamber as a sink. Under no circumstances should waste water be poured into it as water could overflow drain and damage delicate components.

Use nonabrasive cleaners when cleaning unit. Follow directions on containers and rub in a back-and- forth motion (in same direction as surface grain). Cleaners rubbed in a circular motion or applied with a wire brush or steel wool will damage stainless steel. Do not use these cleaners on painted surfaces.

Repeated fuse burnouts indicate a short circuit or overload. Trouble should be located and corrected by a fully trained technician.

When choosing a detergent, select one with a low chloride content. Detergents with a high chloride content will damage stainless steel.

3.7 Oscillating Jet

System

Oscillating jet system consists of one oscillating spray header with machined jets mounted above, below, and on each side of wash chamber (see Figure 3-5). Machined spray jets are angled to reach all surfaces of load.

Oscillating jet system travels back and forth along length of chamber during recirculating/spraying phase function. Jet system is equipped with a safety clutch that stops movement of oscillating header when an obstruction is detected.

Chamber door(s) is equipped with a safety switch to stop washer operation if door is opened during a cycle, and to prevent start of washer operation if door is not securely closed.

Oscillating jet system is equipped with a mechanical clutch to disengage carriage drive if an obstruction is encountered, preventing damage to spray header and load items.

Automatic Detergent Injection System includes a peristaltic pump mounted to washer exterior.

If using alkaline detergent with the injection system, alkaline detergent is automatically injected into chamber sump during Wash treatment of a cycle. Detergent is injected for a programmed time interval while sump is filling with hot building-supply water.

If using acid detergent with injection system, acid detergent is automatically injected into chamber sump during Acid Wash phase of a cycle. Detergent is injected for a programmed time interval while sump is filling.

NOTE: Washer must be equipped with an acid detergent system option for acid detergent to be used.

3.12Vapor Condensing Exhaust System

Washer drain system is piped to automatically cool all drain discharges using building cold water supply.

During draining function of each phase, cold tap water is injected into washer drain line as washer drain discharges are sent directly to building drain system.

During unit operation, exhaust fan removes residual vapors from wash chamber and directs vapors to building exhaust duct.

Vapor Condensing Exhaust System consists of a vapor condenser, mounted to side of washer, and an exhaust fan, mounted on top of washer. Unit width and height are increased by 14" and 7.5" (355 mm and 190 mm).

During unit operation, residual vapors are automatically removed from wash chamber and directed to vapor condenser. Vapors are then cooled, condensed, and directed to building drain system.

3.13 Heat Exchanger Washer is equipped with a steam heat exchanger and valving system to preheat incoming fill water, reducing normal water/solution heat-up time.

System is fully automatic and works during filling phase of all cycle treatments.
