3. SAFETY CONSIDERATIONS

3.1 Harmonized Safety Labeling and Residual Risks

STERIS Corporation uses internationally recognized safety labels. You may see these symbols

used throughout this document and on the Sterilizer. In order to ensure full understanding of the

risks they highlight, please review the General Safety Instructions, document G_E_HC_FE.

3.2 User Training

This sterilizer is a sophisticated piece of equipment. Operators must be trained on how to properly

and safely load and unload the sterilizer to reduce the risk of injury. Proper protective equipment

is also required as the sterilized load will be hot upon removal from the sterilizer.

Maintenance operations for this machine are described in the Maintenance Manual (document

MM_E_HC_FE). To request a copy of this, contact STERIS for information on a replacement.

4.2.1 Operating Cycle Descriptions

The sterilizer comes provided with four default cycles and four test cycles. A possible 20 cycles,

including the four default cycles, are programmable to meet user needs. Editing these cycle

parameters is permitted for service and administrator access levels and is explained more

completely in section 5.11: Administrator Mode - Configure Cycle.

Each cycle button contains descriptions of how the cycle will function.

4.2.2 Cycle 01

This cycle is designed to process metal loads for 3.5 minutes in sterilize phase at 134°C with a dry

time of 25 minutes.

This cycle is designed to process fabric loads for 16 minutes in sterilize phase at 121°C with a dry

time of 10 minutes.

Figure 5 - Cycle 04 Graph Chart

4.2.6 Leak Test (Cycle 16)

This cycle is designed to pass EN285 section 8.2.3 for an empty chamber leak test. It will

condition the chamber and then draw a vacuum to minimal pressure. The sterilizer will lock the

chamber, evacuate and check the pressure again after ten minutes to determine the flow rate of

any leaks in the system. A leak rate greater than 0.13kPa/min (1.3mbar/min) will cause an alarm

to occur and the cycle will not pass.

4.2.7 Warm Up (Cycle 17)

This cycle will perform a forced air removal and short exposure phase to prepare the chamber for

a Bowie Dick test, for Leak Test, or for any other cycle.

4.2.8 Bowie Dick (Cycle 18)

This test cycle is designed for processing Bowie-Dick packs. Bowie-Dick indicators must be

designed to EN ISO 11140-3. The sterilize temperature is 134°C, Sterilize Time is 3.5 minutes,

and Dry time is minimized to 1 minute.

4.2.9 Air Detector Test Cycle (# 7, 8)

This cycle only appears when unit configuration is set to Air Detector: Enabled

This cycle is developed to verify the operation of the air detector test. The system will

automatically induce an air leak into the chamber during this cycle to ensure the air detector

senses air in chamber and cycle aborts.

NOTE: When the air detector successfully detects air inside the chamber, your cycle tape will

show that “Cycle Aborted” – this is indication of a successful detection. The tape record will

appear as follows:

4.2.10 Pass Through (Cycle 20) (# DD)

This cycle only appears when the unit configuration is set to Double Door: Enabled.

A short cycle, the Pass Through Cycle will process control of the sterilizer from one side to the

other. It does not inject steam into the chamber, does not have a sterilize exposure time, and has

no dry period. The load may still become warm if left in the chamber; proper PPE is still required

when handling any load from the sterilizer.

4.3 Chamber Reference Locations for Validation activities

Hospitals are required to develop procedures to validate their equipment. In order to do this, they

require a reference point to the coldest part of the chamber. The reference point for this sterilizer

is located in the chamber drain piping next to the Drain RTD (TE517).

4.4 Cycle Tape Description

The printout reports useful information about each cycle

the sterilizer runs including cycle number, cycle name,

time and date, cycle parameters, and the person currently

signed in who is operating the sterilizer.

During the cycle, data points are printed according to

cycle parameter settings. Transition points are noted by

use of an *.

When “CYCLE PASSED” appears on the Sterilization

Cycle printout it indicates critical cycle parameters were

met.

5.1 Preparing for use

STERIS recommends that the following procedures be completed upon starting-up the unit:

1. See the General Safety Precautions described in User’s Manual section 3, and door opening

instructions below before operating the equipment.

2. Verify that all of the required utilities are available.

3. Open all utility isolation valves to the unit.

4. Turn the dedicated main 3PH and 1PH, if applicable, electrical fused or breaker disconnect

switch(es) to the ‘ON’ position.

5. Turn the Sterilizer main power disconnect switch (‘Main Switch’) to the ‘ON’ position.

6. Turn the control power ‘Key Switch’ 90 degrees clockwise to the ‘ON’ position.

The control system will initialize the system memories, upon which the unit will be placed in the

‘Standby’ mode.

NOTE: In normal use, only the ‘Key Switch’ must be turned to the ‘ON’ position before

operating the unit.

5.1.1 Prepare Loads for Sterilisation Cycles

Before sterilisation, all materials must be thoroughly cleaned.

The Amsco® 600 sterilisation chamber holds commonly used sterilisation modules, wrapped or

unwrapped instruments and equipment. Reference EN285 for limitations of the size and density

for prepared loads.

1. Wrappers may be made of 100% cotton, two- ply fabric, and must be laundered;

alternatively, use commercially available, non-woven disposable wrappers. Recommended

maximum size: 300 x 270 x 600 mm; Maximum weight: 7.5 kg.

2. Limit the weight of wrapped instrument sets or containers to 10 kg to minimize moisture

retention.

3. Recommends STERIS order # AX0710000000000027 wire baskets for individually

wrapped items.

5.1.2 Guidelines for Placement of Various Loads

Refer to EN ISO 17665-1:2006, and instructions below, for load

placement guidelines.

1. Open the steriliser chamber door.

2. Place all packs on edge, and arrange load to allow for maximum

steam exposure so that there is minimal resistance for steam

passage through the load.

3. Place utensils and treatment trays on their edges so that they will

be sterilised and properly dried.

4. Place instrument sets in trays that have a perforated or mesh

bottom. Place flat for sterilisation.

5. In mixed loads of fabrics and hard goods, place the hard goods

on lower shelf. This reduces wetting of fabric packs from

condensate dripping from a hard goods load.

6. DO NOT OVERLOAD steriliser (refer to Paragraph 5.3 for

recommended loading guidelines). Allow for steam penetration

between packs. Avoid contact of load components with the wall

of the chamber.

7. After placing load in chamber, close the chamber door. The

steriliser is now ready to run a cycle. Proceed to appropriate

cycle description in this section.

8. Materials capable of holding water, such as solid-bottomed

pans, basins and trays, should be positioned so that they are

oriented in the same direction and so that condensate can be

eliminated.

NOTE: If a cycle has been run, steriliser and shelves or loading

carrier may be hot.

NOTE: Wear clean gloves and use clean towels as “pot holders”

when carefully placing the load/tray(s) on the chamber shelves or

loading carrier.
