Safety Precautions

WARNING
Ground the product without fail.
In the event of trouble, stop operation
and turn OFF the power.
The product should never be disassembled or
repaired by any other person than a qualified
service engineer.
Failure to observe this warning may result in fire,
malfunction or injury.
Before draining off heating water, open the cover
for at least 2 hours after the end of operation.
Failure to observe this warning may cause hot water
to gush out, resulting in scald or accident.
Do not extend the power cord.
Do not connect the power cord or plug to an
extension cord.
Failure to observe this warning may result in electric
shock or fire.
)(
Heating water is water that is poured into the
chamber to help the heater in the chamber
generate steam for sterilization.
Check the product for sterilization
performance.
Ground
without fail!
Set my power
switch to OFF.
Do not open
valve.
Make sure that the product has been properly
grounded. Be sure to connect one end of grounding
line to the ground and the other end to the grounding
terminal.
Failure to observe this warning may result in electric shock.
Should trouble (burning smell, etc.) occur, set the
power switch to the OFF position, shut down the
main power, and contact the dealer from whom you
purchased the product.
Continuing to operate the product in anything but proper
working order may result in electric shock or fire.
The sterilization performance will vary depending
on such factors as the type and volume of objects
to be sterilized, the arrangement of objects and
the type of container. Therefore, use a sterilization
indicator such as an 䇾OK䇿card for checking the
performance.
Failure to observe this warning may result in accident
or incomplete sterilization.
Do not open the drain valve during
operation.
Do not modify the product.

WARNING
Failure to observe this warning may result in accident
or incomplete sterilization.
Failure to observe this warning may destabilize control
of the product or result in incomplete sterilization.
If the containers are placed with their openings facing
upward, it is hard for air to sufficiently escape from the
container and for steam to sufficiently penetrate inside,
thus resulting in incomplete sterilization.
Do not sterilize objects in a steam
impermeable container or bag.
Do not block the holes or temperature
sensor in the chamber with objects.
When sterilizing only containers such
as beakers, flasks and test tubes,
place them with their openings facing
downward or lay them on their sides.
Do not seal the object container tightly.
Use a porous cap or loosen the cover sufficiently.
Failure to observe this warning may result in accident
or incomplete sterilization.
Failure to observe this warning may destabilize control
of the product or result in incomplete sterilization.
Do not place objects on the
temperature sensor in the chamber.
When sterilizing waste, pour about
300 ml of water into the sterilization
bag and sterilize the waste with the
bag open.
When using the sterilization bag, be
sure to put it in the stainless steel
basket included with the product and
set it in the chamber for sterilization.
Sterilizing without water in the bag or with the bag
closed may result in incomplete sterilization.
If the sterilization bag is put directly in the chamber, it
may block the temperature sensor or it may be pinched
between the chamber opening and the cover packing,
resulting in trouble with the product.

(Continued)

CAUTION
Connect power cord of the product
to its own dedicated outlet.
Nothing should be placed on the
power cord.
Do not use staples or nails to anchor
the power cord.

after the end of operation may result in burns.
Failure to observe this caution may result in electric
shock.
Connect the power cord to a dedicated outlet as
shown below.
<MLS-3751/MLS-3751L>: Single phase, AC Local Voltage
<MLS-3781/MLS-3781L>: Single phase, AC Local Voltage
Failure to observe this caution may result in ignition or
malfunctioning.

Your fingers may be pinched and injured.
Insert the hose securely.
Be careful about the position of the
exhaust hose insertion holes.
Be sure to insert the hose in the tank into the holes
at the back inside the exhaust tank.
Failure to observe this caution may cause large steam
leaks from the tank on the rear side.
Since high-temperature steam will escape when the
cover is opened, wait until the steam dissipates.
During this time, keep your head away from the
product.
Failure to observe this caution may result in burns.
Keep your head away from the safety valve vent
when steam escapes.Set the power switch to
䇾OFF䇿㻌position, shut down the main power and
contact the dealer from whom you purchased the

Be sure to use the exhaust tank attached to the product.
If the packings of the exhaust hose have not been
inserted sufficiently, steam may escape and result in
burns.
Be sure to insert the hose down to the bottom of
the exhaust tank on the rear side.
Incomplete hose insertion may cause steam or hot
water to spill over the tank.
When using the exhaust tank attached
to the product, insert the exhaust hose
packings securely in the holes of the
exhaust tank.
Do not allow children to use or play
