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
to follow your local Health Authority’s recommendations.
ST-IM29h P3/12
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.
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.
THE USER SHOULD BE A WARE 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
consult a qualified microbiologist or Authorized Person.
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 A WARE OF THE FOLLOWING
LIMITATIONS DURING USE
a. Never use trays or cassettes without perforations as
this will result in a non-sterile load.
b. Do not process wrapped, sealed or porous goods or
fluids in this autoclave.
c. Not to be used in zones of risk associated with
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.
f. When sterilising instruments not of solid metal
construction, the manufacturer of the instrument must
be consulted about its suitability for autoclaving,
P4/12 ST-IM29h
Note 5.
GENERAL POINTS TO REMEMBER DURING USE
a. Close the chamber door properly before selecting the

SES LS3
AUTOCLAVE
GENERAL INFORMATION NOTES
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 3 Autoclave (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 DA T A ’
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.
Conditions of Safe Use:-
a. Indoor Use.
b. Altitude up to 2000 metres.
c. Temperature 5°C to 40°C.
d. Maximum relative humidity 80% for temperatures up
to 31°C, decreasing linearly to 50% relative humidity
at 40°C.
e. Mains supply voltage fluctuations not to exceed ±10%
of the normal voltage.
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.

17. If a cycle “With Drying” is selected then commencement
of the drying phase is indicated by the display ‘dry’
accompanied by a rapid intermittent audible signal.
When this signal is heard, maximum drying will be
achieved if the chamber door is opened halfway and
then closed until it touches the metal catch on the front
fascia panel, leaving a small gap (approx. 1cm) for
ventilation. Instruments can be taken out any time
during the drying phase, but best results will be
achieved by waiting until the automatic cycle is
complete.
18. On completion of a sterilizing cycle ‘without drying’,
the display ‘End’ will appear, accompanied by a brief
audible signal. When the door is opened to remove
load the display will change to ‘door’.
19. On completion of a sterilizing cycle ‘with drying’ (where
chamber door is opened slightly during the drying
phase), the display ‘End’ will appear briefly
accompanied by an audible signal and followed, after
a few seconds by ‘door’.

UK Guidance
WARNING
Chlorine, even in the concentrations found in tap
water, can cause stainless steel to crack and could
damage the chamber. Disconnect from the mains
electrical supply before cleaning the Autoclave.
21. Keep chamber trays, door seal and chamber face
clean. These should only be cleaned with a lint-free
cloth. Clean the outside of the autoclave by wiping
down with a cloth dampened with a 70% solution of
industrial methylated spirit (IMS) and water. Allow to
dry by evaporation.
Note: Do not use abrasive powders, chemicals, or
solutions containing chlorine to clean the autoclave.
22. The reservoir must be drained weekly and be allowed
to dry (Fig. 6). When refilling see section 6 and
‘Reservoir Water Quality Caution’ on page 3, DO
NOT USE TAP WATER. Regular cleaning of the
reservoir will reduce the effects of excessive handpiece
lubricant which could be detrimental to the function of
the autoclave.
23. Attention to the following will increase the life of the
your Little Sister 3 Autoclave:
a. After use leave chamber door slightly open.
b. At weekly intervals, lightly clean door seal and
chamber face with a lint-free cloth.
Inspections can be arranged by contacting the Eschmann
After Sales Service Department, see inside cover for contact
details. Eschmann can also provide comprehensive service
contracts, which cover preventive maintenance to ensure
trouble free operation of your autoclave as well as an annual
inspection of the pressure system to satisfy the requirements
of the Pressure Systems Safety Regulations 2000.
MAINTENANCE
(Ensure you have read pages 3-5)
Fuse Renewal
25. Fuses are fitted at the back of the autoclave (Fig. 1,
detail). For fuse ratings refer to ‘TECHNICAL DATA’.
To extract a fuse switch ‘off’ the unit and disconnect
from the mains power supply, insert a screwdriver or
small coin in the slot of the fuse holder and twist it
counter-clockwise. After inspecting or renewing a fuse,
reverse the above procedure to re-secure fuse holder.
Preventive Maintenance Agreement
26. We would strongly recommend that a ‘P.M.A.’ is taken
out on your Little Sister 3 Autoclave. Although the
autoclave requires minimal maintenance, it is important
to have the autoclave checked and calibrated at
regular intervals. This ensures that the exacting
conditions necessary for sterilization are maintained
throughout the unit’s working life.
ST-IM29h P7/12
Error Correction
27. If, after switching ‘on’ power there is no visual display,
or audible tone, first check power supply connections.
Also check all 3 fuses at rear of unit (see Fuse Renewal).
If any error occurs during a cycle (i.e. any time after
selecting a programme), the cycle will abort and provided
power supply to the unit is maintained, the error will be
indicated by one of the visual displays shown in Table 1.
If power fails during a cycle, check supply conditions,
fuses, and connections as indicated in this paragraph.
Overheating
28. In the unlikely event of overheating, the red overheat
warning lamp (Fig. 1) will illuminate. If this happens,
first allow approximately 10 to 15 minutes for the
autoclave to cool, then check the water level in
reservoir. When the water level is correct, press the
button marked ‘PRESS TO RESET’ at the rear of the
cabinet (Fig.1, detail) and re-start the cycle in the
normal way. If the fault persists, switch off the unit and
call an Eschmann trained engineer.
Note: Should the ‘press to reset’ thermostat operate
in a nil water condition, the chamber temperature is
below 138°C. The maximum chamber temperature
on overheat, to melt the thermal fuse is 250°C.
Cleaning the Filter
29. The Little Sister 3 Autoclave is fitted with a filter which
will require cleaning by a qualified service engineer.
This should be carried out at least annually.

Printer Output
The printer output gives the following information:
¬ Manufacturer’s name Eschmann Equipment
¬ Machine type SES Little Sister 3
¬ Serial number Alpha numeric code
¬ Cycle type e.g. 134°C no drying
¬ Time and date started hh:mm:ss on dd:mm:yy
¬ Counter reading Fiv e di gits wit h leading zeros
¬ Time/temp information Time every 22 secs
(approx.) + temp. + graph
of temperature.
¬ Cycle ended message The ‘cycle end’ is defined
as the end of the
sterilizing phase.
¬ Time and date ended hh:mm:ss on dd:mm:yy
If an error occurs during the cycle, it is recorded with date
and time on the printout and the message ‘CYCLE FAILED’.
Errors are designated by error codes as follows:
ERR1 -Faulty temperature sensor/channel
detected (‘ELECt’ on display)
ERR2 -Door open during cycle
ERR3 -Chamber did not fill with water
ERR4 -Water loss early in cycle
ERR5 -No heat
ERR6 -Control temperature low
ERR7 -Control temperature high
ERR8 -Monitor temperature low
ERR9 -Monitor temperature high
These error codes will generally require investigation by
an Eschmann trained engineer.
