Requirements for Installation

Before Using this unit

CAUTION!

6. Choose a correct power distribution board or receptacle

• Choose a correct power distribution board or receptacle that meets the unit’s rated electric
capacity.

Electric capacity: SA300: AC100V, 2.2A

SA320: AC100V, 2.2A

NOTE)

There could be the case that the unit does not run even after turning ON the power. Inspect
whether the voltage of the main power is lowered than the specified value, or whether other
device(s) uses the same power line of this unit. If the phenomena might be found, change the
power line of this unit to the other power line.

7. Before/after installing

• It may cause injure to a person if this unit falls down or moves by the earthquake and the
impact. etc..To prevent, take measures that the unit cannot fall down, and not install to busy
place.

• Touching the shaking parts may cause injure to a person during the operation. To prevent,
take measures that putting up a notice of operating, making an enclosure etc..

8. Handling of power code

• Do not entangle the power cord. This will cause overheating and possibly a fire.

• Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire

and electrical shock.

• Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order to
prevent it from being damaged and to avoid a fire or electrical shock.

• Keep the power cord away from any heating equipment such as a room heater. The cord's
insulation may melt and cause a fire or electrical shock.

• If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off the
power at the rear of this unit and shut off the main supply power. Then contact your nearest
dealer for replacement of the power cord. Leaving it may cause a fire or electrical shock.

• Connect the power plug to the outlet which is supplied appropriate power and voltage.

Sequence of Operation

1. Fix the sample containers.

Operation Method

• Before turning on the power switch, fix the sample containers firmly.

• The quantity of sample containers to be installed is as shown in the

following table.

Separating Funnel Holder 5 4 4 4 3

100 200 300 500 1000

2. Turn on the power.

3. Set the shaking time.

4. Adjust the shaking times.

Erlenmeyer Flask Holder

• Before turning on the power switch, check if the timer knob is OFF
and if the speed adjusting knob is at the lowest speed.

• When the power switch is turned on, the power lamp is ON.

• When the sample container is installed, turn the timer dial, and set it

to the required time (min).

• In continuous operation, adjust the dial position to "CONT".

• Shaking times shall be set by the speed adjusting knob.

Since the scale has its variable range divided evenly, use this for
reference.

CAUTION!

If used at the max shaking times, such shaking times could exceed the
standard value in the area of commercial power frequency 60 Hz. If
shaking is performed in the too wide range, or if the main unit vibrates
widely, reduce the speed-regulating dial.
Shaking times could also rise according to the condition of the load. In
such cases, slightly reduce the speed-regulating dial similarly.
Shaking times for each scale (reference) are as shown below
approximately:

Sequence of Operation

It is possible to make vibrate the main unit, when the setting sample is
heavy or the shaking time is large. Please refer to the table of
vibration-proof and operate not to move by sample or shaking time.

CAUTION!

In the early stage after supplying power, the shaking times may be
10-15% lower than the set value. Perform the running operation for
about 15 min. Then, the shaking times will stabilize.

10

Handling Precautions

WARNING!

If a problem occurs

If smoke or strange odor should come out of this unit for some reason, turn off the power key
right away, and then turn off the circuit breaker and the main power. Immediately contact a
service technician for inspection. If this procedure is not followed, fire or electrical shock may
result. Never perform repair work yourself, since it is dangerous and not recommended.

Substances that cannot be used

Never use explosive substances, flammable substances and substances that include explosive
or flammable ingredients in this unit. Explosion or fire may occur. (Refer to page20 “List of
Dangerous Substances”.)

CAUTION!

Take care not to load too much sample

If too much sample is loaded, the shaking speed will be reduced, or the main unit will vibrate.
Do not start operation with any overload.

Do not step on this unit

Do not step on this unit. It will cause injury if this unit fall down or break.

Do not put anything on this unit

Do not put anything on this unit. It will cause injury if fall.

During a thunder storm

During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and
the main power. If this procedure is not followed, fire or electrical shock may be caused.

Speed adjustment

The shaking speed of this unit is adjusted appropriately at the shipment from factory.
If the power voltage fluctuates widely, or if the motor temperature rises abnormally, the speed
could be changed more or less. If any abnormality including abnormal vibration and shaking
main unit is detected, reduce the speed by means of the speed adjusting knob.
If max. specified revolution is exceeded, the abnormal vibration or noises could be caused, and
thus be caused failure.

Operation method

Operate this unit with the method specified by this operation manual. If operated in ways other
than specified in this operation manual, any failure or accident could be caused.
If operated in ways other than specified in this operation manual, the product is not guaranteed.

11

Handling Precautions

CAUTION!

Sample installation method

The sample container mounting holders for separating funnel, Erlenmeyer flask, centrifugation
tube and test tube are provided respectively as nonstandard options. Select them according to
the purpose, and mount them on the shaking table of the main unit.
To shake the separating funnel, set the shaking table at vertical position (vertical shaking type),
and enter the positioning pins of the holder into the two pipe holes provided in the table (see the
sketch drawing), and then fix them firmly.
When using Erlenmeyer flask, set the vinyl chloride box type holder firmly on the table of the
main unit placed at level (horizontal shaking type) (See the illustration on Page 7).
Also, when using centrifugation tube and test tube, place the main unit horizontal.

Preparing timer

This unit incorporates a 60-min meter for timer. If it is necessary to operate this unit for a longer
time, set the timer to CONT. Continuous operation is available.

Return after power failure

When power is supplied after a power failure, the device automatically starts operation again with
the same state as just before the power failure. It is danger that the device starts unattached
operation after a power failure. We recommend for you to turn off the switch of this unit if a
power failure occurs during operation.

When the main unit vibrate using it

Please use it as follows when the main unit vibrate or begin.
It is considered becoming unbalance of the unit to use for a long time.

①Decrease the shaking time not to vibrate it.
②Decrease the weight and not to vibrate position.
③If not to decrease the shaking time or the weight, please fix the unit with anchor.
