Note

●Make sure to install the unit on a flat, sturdy surface floor.

Lock all four casters.

●Avoid locations where the unit is exposed to air containing

large amounts of moisture, salt or sulfur, as these could

adversely affect the unit.

●The door opens out in a counterclockwise direction. Make

sure to allow sufficient clearance from impediments (walls,

posts, etc.) when positioning the unit.

●Allow at least 5 cm of free space between the back and left

sides of the unit and the nearest wall. Placing the unit too

close to the wall will cause heat to build up inside the unit

and that could cause the unit to malfunction.

Installation

Preparation for Use

At least 5 cm

●Allow at least 5 cm of free space between the back and left

Set the switch inside the main unit to match the elevation

of the installation location. (When the unit shipped from the

factory, it is set for an elevation of between 0 and less than

500 m.)

●If the switch setting needs to be changed, ask your dealer

to do it for you.

●If large quantities of culture or other liquids are sterilized,

the delay of reaching time could be occurred between the

chamber reaching time to setting temperature and the liquid

in containers reaching time to setting temperature.

Set the sterilization time a little longer than usual time when

sterilizing such items.

Precautions for sterilizing of liquids such as cultures and chemicals

●Never use the unit to sterilize cultures or chemical solutions

containing elements (salt water, strong acids, strong alkalis)

that could cause the inside of the chamber (made of stain-

less steel) to corrode.

Corrosion could cause the unit to malfunction prematurely.

Timer setting = sterilization time + delay time

●Sterilization performance can vary depending on the type

of items being sterilized, their quantity, how they are loaded

into the autoclave and the containers used to hold them.

Therefore, be sure to use a sterilization indicator such as

an “OK card” to confirm sterilization performance.

Checking of sterilization performance

●Only use Type 1 borosilicate glass containers and do not

overload the stainless baskets. Do not squeeze bottles ag-

ainst each other.

●Place items that might entrap the water steam, such as bo-

wls or pitchers, upside down or on edge so they will be ste-

rilized properly.

●Place sterilizing glass containers such as beakers, triangu-

lar flasks, test tubes and the containers upside down or on

edge.

Placing glass containers upright makes it harder for the st-

eam to reach the bottom and can result in incomplete ster-

ilization.

●Only use heat resistance containers and do not overload

the stainless baskets. Do not squeeze bottles against each

other.

●If large quantities of culture or other liquids are sterilized

with using plastic containers, set the sterilization time a little

longer than usual time.

Plastic containers convey heat slowly and can result in inc-

omplete sterilization, if sufficient time is not allowed.

Sterilizing of items with using plastic containers

●It is not designed to process flammable liquids nor liquids

in containers that are not designed for sterilization (e.g.co-

ntainers having screw caps, non vented stoppers, etc.) ,

therefore doing so may be dangerous. Any alteration of the

sterilizer which affects its design could void the warranty

and may violate state and local regulations or jeopardize

insurance coverage.

Items to be Sterilized (Continued)

2. If media spills are discovered in the bottom of

chamber, proceed as follows:

1. Exhaust tank setup

(1)

Remove the exhaust tank from the main unit and, from

the opening at the top, fill the tank with water up to the

LOW level mark.

(2)

Insert the exhaust hose that is connected to the interior

of the main unit into the opening at the top of the tank.

Push it in securely until the gasket is firmly engaged.

(3)

Load the exhaust tank into the main unit with taking

care the exhaust hose not to bend or twist.

3. Pour water for evaporation into the chamber.

(1)

Turn the handle counterclockwise until it stops. Open the

door with turning the arm counterclockwise.

(2)

Close the drain valve.

(3)

Pour in water unit the top edge of the water level fitting on

the heater cover is covered. The level of water will be lower

after each sterilizing cycle, therefore this water must be rep-

lenished.

Pour water for evaporation

MLS-3020U units : 2 liters

MLS-2420U units : 1.5 liters.

Supplementary note

Starting Operation

Turning the gasket only one direction during insertion can

cause the hose to become twisted and possibly lead to

malfunctions.

Turn the gasket alternately to the left and right when

inserting it.

Note

Chamber should be cleaned daily when processing

media. See page 29 (Maintenance and care) for

cleaning.

Note

The amount of water in the exhaust tank increases in

every operation of sterilizer. If the water reaches the HIGH

level mark, discard this water and pour new water up to

the LOW mark. Do not try to pull the tank out from the

main unit, if the exhaust hose is still attached.

6. Close the exhaust knob.

●Close the exhaust knob by turning it clockwise as far as it

will go.

4. Turn the power switch on.

●The sterilization temperature and sterilization time appe-

ar alternately on the digital display to indicate that power

is being supplied. This condition is called as the standby

status.

5. Insert items to be sterilized.

●Do not place items to be sterilized directly on the top of

the heater cover. Put them in stainless steel baskets and

place them gently into the chamber.

●Remove any caps from empty jars, canisters, and nonpo-

rous containers and place them upside down in the stai-

nless basket to facilitate sterilization. Place hard goods

(i.e.metallic instruments) on the bottom when processing

mixed loade combining fabrics and hard goods. This pre-

vents wetting of wrapped packs from condensed water

dripping from the hard goods load.

●Also refer to page 17-18 (Items to be sterilized) for more

infomation on placement of items to be sterilized.

Be careful not to block openings inside the chamber or

inflict the impact on sensors, when placing the items to

be sterilized into the chamber. Doing so could cause the

unit to malfunction.

Performing of sterilization with opening the exhaust knob

will cause all water for sterilization to evapoirate, resulting

in a dry scorch. There is also a danger to cause burns, if

steam and hot water are forced out from the opening of

the exhaust tank under high pressure. Always check to

make sure that the exhaust knob is cloded before start-

ing the sterilization.

Note

Distilled water is ideal for using as water for evaporation.

If distilled water is unavailable, tap water may be used.

Never use well water, saltwater or hard water. If these

water are used, they could cause the inside of the cham-

ber to corrode or mineral deposits to form.
