2-1 Setup environment
Setup2
Bad setup environment may damage
the product and worsen the function.
WARNING
Be careful with setup environment
Select the setup location as below.
No inflammable solid, liquid and gas around the unit.
Range of ambient temperature is from 5℃ to 35℃.
No dew condensation
Fewer humidity and dripping
Fewer dust
No direct sunlight
Good ventilation
Even and stable
Since the unit uses water, water leakage must flow into
drain when leak of water occurs.

2-2 Utility connection
（1）Check the voltage, phase and capacity of
power source connecting to the product.
Required power source is as shown on right
table.
（2）Make sure of the type of outlet and plug mains connector.
Model
A-1000S
Required power source
Capacity
AC115V 15A
Voltage
Excess current may burn cable or cause
fire.
WARNING
Do not use branching socket and
power strip.
Wrong connection may cause fire or
electric shock.
WARNING
Make sure of the voltage, phase,
capacity and the type of outlet. Do not connect earth wire to gas pipe or
water pipe for preventing electric shock.
WARNING
Connect earth wire properly.
When connecting to power source, do not
use branching socket and power strip.

3-1 Preparation
（1）Place the main body on the bath and
set it up on the point of use.
（2）Remove the cap of water supplying
nozzle.
（3）Install hose for drainage (bore diameter:
16mm) onto overflow nozzle and also install
water-supplying hose (bore diameter: 12mm)
onto water-supplying nozzle tightly for
preventing leak.
（4）Connect decompression system and suctioning
nozzle with using vacuum hose (bore diameter:
6mm).
※When reducing the pressure at only one point,
using two suctioning nozzles with Y-shaped joint
simultaneously can shorten the time required for
decompression.
Operation

Pump and aspirator that are clogged with
dust and cotton waste will worsen the
attainable vacuum degree. Also, they will
cause glitch on motor.
CAUTION
Make sure that no foreign
substance such as dust is adhered in
the bath.
If the organic solvent is dissolved into
the water, attainable vacuum degree will be
worsened or metal aspirator and driving part
will be damaged. Also, it may cause nasty
smell or fire.
When suctioning organic solvent,
use trap and do not let solvent
mix into the bath.
CAUTION
Notice 1 When water temperature in the bath
rises during the operation, it may worsen
the attainable vacuum degree, and water in
the bath may flow upstream. Therefore,
circulate the cooling water or conduct
overflow to keep the same water temperature
for avoiding the trouble. Also, use
store-bought backflow prevention valve. Water supplying hose

Sucking in
※ When the solution can not perform overflow for
maintaining water temperature because of
effluent regulation, use cooling trap to
prevent the interfusion or change the water
in the bath regularly.
Notice 2 When the solvent mixes into the bath,
it will worsen the attainable vacuum
degree and may cause back-flow.
Also, when the solution vapors, it may
cause nasty smell or fire.
※ Attainable vacuum degree of the unit depends
on water temperature and water quality.
※ When water can not be overflowed, it is effective
to use immersion cooler or cooling water circulating
device combining with cooling coil, which is one of
the options.

Fill the water into the bath up to the point
where flow nozzle supplies water.
※If the water supply is too much, water may
overflow from the bath.
※Though the water supply is controlled
properly, it may be changed because of the
change of water pressure. Pay attention to
the water level during overflow.
2. Water supplying into bath
Make sure that the power switch is off before plugging the mains connector into outlet.
3.Connecting mains connector

Decreasing pressure at 2 points simultaneously
※ When releasing decompression at one
decompression container and sucking in air,
air bubble will be sucked into the pump
and attainable vacuum degree will be
worsened. In this case, water may flow
upstream into other decompression container.
When decreasing pressure in both containers,
set up stop cock in each decompression line
and close the stop cock before releasing the
decompression.
