Service Manual
A Service Manual containing technical description, complete maintenance procedures and an illustrated list of spare parts is available on request from the Eschmann After Sales Service Department.
Reservoir Water Quality Caution
a.Eschmann recommend filling the reservoir with ‘Sterile Water for Irrigation’. This is low in dissolved solids and has a low microbial count. In the U.K. the Department of Health recommend that ‘Sterile Water for Irrigation’ is used in bench-top Autoclaves (NHS Estates document HTM2031).
b.If ‘Sterile Water for Irrigation’ is not being used then Eschmann strongly recommend the use of either distilled water, deionized water, purified water or water treated by the reverse osmosis process. These types of water are low in dissolved solids and can help reduce the effects of tap water detailed below.
c.DO NOT USE TAP WATER, this is high in dissolved solids and can deposit lime scale, block filters and cause damage to the pressure vessel.
d.Eschmann also recommend changing the water in the reservoir on a weekly basis, with the type of water detailed in ‘a’ (or ‘b’) above. This will reduce the build-up of contaminants in the water that may cause blocked filters and/or damage to the pressure vessel. Your local Health Authority may suggest that you change the reservoir water more frequently. Eschmann advise you tofollowyourlocalHealthAuthority’srecommendations.

WARNING
READ NOTES (1-5) BEFORE USE
The use of this autoclave should be under the control of a responsible Person with sterilization training. The user remains responsible for ensuring that the load is suitable for the process adopted.
Note 1.
THE USER SHOULD BE AWARE OF THE FOLLOWING POSSIBLE HAZARDS
a.Burns to the user caused by hot accessible surfaces of the load, burns to the user caused by high temperature internal surfaces of the chamber, scalds to the user caused by hot water and/or steam from the reservoir, scalds to the user caused by hot water from the chamber on opening the door, scalds to the user caused by hot water and/or steam from overfilling the reservoir.
b.The hazard of scalds and burns from contact with hot surfaces are greater during validation with the cover removed which also exposes the risk of electric shock. Validation should therefore only be carried out by a qualified engineer.
c.Infection, caused by contact with water in the reservoir if the reservoir is not drained, left to dry and recharged at regular intervals as described in these instructions for use (see paragraph 22) to prevent possible contamination.
d.The autoclave indicates a successful cycle, but the load remains non-sterile because the load is not suitable for the steam sterilization cycle. All loads and loading conditions must be validated. It is recommended that the user consults the instructions for use of the items to be autoclaved and if in doubt consultaqualifiedmicrobiologistorAuthorizedPerson.
regarding the maximum temperature the instrument can withstand. This is necessary as the sterilizing temperature for 121ºC cycles may be exceeded (typically to peaks of 130°C) during the drying phase under certain conditions such as small loads.
g.The Autoclave will discharge steam during and at the end of some cycles. Ensure the autoclave is not positioned close to heat or smoke detectors as these may be activated by the release of steam.
Note 3.
THE USER SHOULD FOLLOW THESE ELECTRICAL SAFETY MEASURES
a.This equipment must be earthed.
b.Switch ‘off’ unit and disconnect from mains power supply before renewing fuses.
c.Switch ‘off’ unit and disconnect from mains power supply before checking and cleaning the autoclave.
d.Do not attempt to service this equipment internally.
Note 4.
THE USER SHOULD FOLLOW THESE GENERAL SAFETY MEASURES
a.Do not fill the reservoir during a sterilizing cycle.
b.Do not cover the ventilation louvres.
c.Do not use abrasive powders, chemicals, or solutions containing chlorine to clean the autoclave.
d.Always allow unit to cool before attempting to open the chamber door.
e.If an error display appears during a cycle, do not switch-off power until discharge of hot water or steam into the reservoir has stopped. Do not attempt to open chamber door until unit has cooled and internal pressure has fallen sufficiently to release pressure safety bolt. Also see ‘Safety Checks’ page 7.
Note 2.
THE USER SHOULD BE AWARE OF THE FOLLOWING LIMITATIONS DURING USE
a.Never use trays or cassettes without perforations as this will result in a non-sterile load.
Note 5.
GENERAL POINTS TO REMEMBER DURING USE
a.Close the chamber door properly before selecting the required programme.
b. Do not process wrapped, sealed or porous goods or b. Always leave the chamber door slightly open after
fluids in this autoclave. |
use. |

c.Not to be used in zones of risk associated with c. Never use tap water see section 6 and ‘Reservoir
flammable anaesthetics.
d.The Little Sister 3 is designed to sterilize instruments, NOT TO WASH THEM. If instruments are not cleaned this may compromise the efficiency of the sterilization process.
e.These Autoclaves are not suitable for instruments or items with narrow lumens.
Water Quality Caution’ on page 3.
d.Ensure instruments are free from debris before placing them in sterilizer chamber.
e.Use the ‘tray lifter’ to remove the sterilized load.
f.Keep chamber trays and chamber face clean.
g.Clean door seal and chamber face with a lint-free cloth at weekly intervals.
f.When sterilising instruments not of solid metal h. Regular maintenance (every three months is
construction, the manufacturer of the instrument must be consulted about its suitability for autoclaving,
recommended) is required to ensure continued safety and reliability

AUTOCLAVE
GENERAL INFORMATION NOTES
Conditions of Safe Use:-
IMPORTANT
The design of the autoclave pressure vessel is approved by a third party to PD5500 Cat.3. The pressure vessel is constructed and tested to BS3970 Parts 1 and 4. In order to ensure safety and to comply with UK regulations, the vessel and fittings should be inspected by a ‘competent person’ at intervals of no more than 14 months. This can be carried out by an Eschmann trained engineer.
The Little Sister 3Autoclave (Standard and Long) is designed for the sterilization of unwrapped instruments, utensils and other items. It operates automatically at the touch of a single programme selector touch button, and has four programmes 134°C and 121°C, both with and without drying (see Important Note below right). The Autoclave is capable of 4 cycles per hour when the ‘134°C Without drying’ programme is selected. For sterilization cycle times, refer to the ‘TECHNICAL DATA’ section on page 12.
Little Sister 3 Autoclave, safety features:-
a.Pressure Door Lock. The door is mechanically locked at pressures above 0.14 bar.
b.Door Interlock Switch. This prevents programme starting if door is not properly closed.
c.Electrical Door Lock. This prevents the door being opened inadvertently by the operator once the cycle has started and holds the door closed until the end of the cycle. It will also keep the door closed under all fault conditions.
d.Pressure Relief Valve (safety valve). This valve safely releases excess pressure (i.e. above 2.6 bar).
e.Microcomputer. The microcomputer constantly monitors all key functions. If an error arises, it immediately stops the cycle, discharges pressure, and causes the appropriate message to be displayed (See Error Correction para. 27).
f.Overheat Control. The microcomputer operates in conjunction with an independent manual reset thermostat to protect the heating element from overheating. The autoclave is also fitted with a fusible link which, should overheating occur, will cut all power to the heating element and microcomputer and operate the manual reset thermostat, leaving only the red overheat warning lamp illuminated on the front panel.
Declaration
The design of the autoclave pressure vessel is approved by a third party to PD5500 Cat.3. The pressure vessel is constructed and tested to BS3970 Parts 1 and 4.
Note: This equipment is defined as:
Installation Category 2 (Overvoltage Category 2) Pollution Degree 2 (in accordance with IEC664).
a.Indoor Use.
b.Altitude up to 2000 metres.

f.No other voltage fluctuations specified by the manufacturer.
Note: If it is required to operate this Autoclave outside of these conditions, contact Eschmann Equipment at the address given in these instructions.
IMPORTANT NOTE:
UK Customers should arrange for this equipment to be installed by an Eschmann Trained Engineer before use. (For free installation and service details see page 2). Also see ‘Safety Checks’ page 7.
The preset sterilizing temperature for your Little Sister 3 Autoclave is displayed on a temporary label affixed to the front of the unit. All programmes can be deactivated or reactivated by an Eschmann Trained Engineer, on request.
