chamber with 0.75 Litres of distilled or de-ionised water.

DO NOT USE TAP WATER OR OVERFILL CHECK WATER LEVEL AFTER EVERY CYCLE

3.2 Loading

Place the instruments into the instrument basket or
cassettes, and place in the unit.

Please see section 7 — Technical specification for loading capacities

3.3 Closing

Always place the lid on the autoclave with the Depressurization
Valve (A) open. Align the two black triangles on the
cover and body as shown in (F3) and turn in a clockwise
direction (F1) ensuring the lid is completely closed (F2).

3.5 Starting

Start the sterilizing cycle by pressing bution (8).

Lights: L1 illuminates GREEN
L2 illuminates ORANGE

As the temperature rises, air will be displaced by
steam through the Air Bleed Device located in the
lid, until it closes with an audible “click’, sealing
the unit,

The Pressure Rise Indicator (C) will rise indicating the
unit is now pressurized.

Sterilizing Temperature is reached when:

Lights: L1 illuminates GREEN
L2 flashes ORANGE
L3 illuminates YELLOW

Sterilizing Cycle is completed when:
L1 illuminates GREEN
Ld luminates GREEN

Note: Ld remains GREEN until a new cycle is started
or the unit is disconnected from the mains power.

3.6 Depressurizing

Once the sterilizing cycle has been completed, the unit
needs to be depressurized and allowed to cool down
before the lid is opened and sterilized instruments can be
removed,

The time taken to reach the point at which this is safe to do
s0 can be shortened by manually depressurizing the unit,
Open the Depressurization Valve (A) by tuming slowly in
an anti-clockwise direction, The Pressure Rise Indicator
(C) will drop once the steam has been released.

WARNING!
There will be a visual and audible release of steam
from the rear of the Steam Duct.

Section: 7 Technician Specification

In the unlikely event that something should go wrong,
we have incorporated a number of safety features to

ensure that your autoclave remains safe at al times,

Safety features

1. Located in the rear of the lid, beneath the cover, is a
spring called the Gasket Offset Device (GOD Spring),
“This has been designed to prevent pressure building
up if the lid has been incorrectly fitted.

DO NOT TAMPER WITH THIS SAFETY DEVICE

2. If for any reason, the temperature falls below the
minimum required st ing temperature, the Error
Light (L5) will be illuminated. Switch the unit off and
leave to cool down, Then switch back on, Check
gasket, water level and refil if necessary. Run another

cycle and if the issue persists contact a Tuttnauer
technician.

3. If there is an electrical or electronic failure resulting
in a build-up of pressure – in excess of normal
operating pressure – one or all of the following safety
features will be activated,

i) A pressure relief valve installed within the lid handle
(E) will loudly and rapidly “Vent” steam allowing its
exit via the Steam Duct (F)

ii) The gasket will “extrude” through the slot in the
rear of the lid rapidly releasing excess pressure and
steam.

iii) A non-resettable thermal fuse is located in the
base of the unit. This will activate automatically if an
error was to occur with the unit,

Note: Should any of errors listed occur, please follow
these steps:

Do not touch the unit.
b) Switch off at the wall socket and un-plug

©) Allow temperature and pressure to drop before
touching the unit or removing your instruments
d) Do not attempt to re-start the cycle
