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 the product 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 suppl ied appr opriate pow er and voltage . If the p ow er cord
is connected the supply which is also connected to a aspirator or a vacuum pomp etc., with no
sufficient power and voltage, the product may not operate properly because the power would fall.
Piping
•
Vacuum hoses (outside diameter 12 x inside diameter 6mm) are required. These are not included in
accessories.
•
Refer to figure below in order to pipe. Stickers that indicate where to connect are attached at the rear.

Warn ing
Warning
WarningWarning
Approaching Thunderstorm
•
If a thunderstorm approaches in the distance, immediately turn off the power at the rear panel and shut
off the supply power. Leaving the power turned on may cause a fire or electrical shock.
During Power Failure
•
In case of power failure, the leak valve opens, the atmosphere in the system of the rotary evaporator is
released, and the solenoid valve for control is shut. It prevents spout of organic solvent in distillation,
and back-flow of water from the aspirator.
•
After power failure was repaired, the set mode is automatically switched to the fixed value control. The
indicator displays the set pressure blinking. The leak valve opens and the solenoid valve for control
shuts.
•
The product is not interlocked with neither the rotary evaporator nor bath. Care should be taken that
each movement of them is not the same after the power failure. If power failes wh ile the evaporator is
revolving, it starts revolving after power failure was repaired.
•
Make sure that the aspirator and the cold circulating device etc. is working properly when you start
the vacuum control again.
Handling Precautions
Aspirator Shutdown
•
The device must be stoppe d be fore y o u st op the aspirator. If not,ba ck- f low ,from the aspirator's bath to
the pressure senser,may occur.In case of back-flow, the indicator may not display accurate values,or
the sensor may be damaged.
Using the Product
•
The product is not a pressure measurement apparatus. Do not use it for calibration.
•
There are not functions for vacuum and pressure raising in the product itself. The product is used to
control the pressure in the system. The operation runs in order to reach to the pressure which is set
depending on the rise of pressure, by connecting to a decompression device of aspirator etc. The rise
of pressure (depending on the steam pressure of sample) is that occurs when the rotary evaporator
operates distillations.
Corrosive Samples
•
The product's connections to gas are made of materials given in Table 1. Especially metal piping parts
and gas-joint for pressure sensor are corroded by strong acids and strong alkalines. Do not use the
product for distillation of strong acids and strong alkalines.
•
As the product's gas-joints are exposed to low-concentrated steam that can not be trapped by the
condenser (cooler),the joints are not corroded soon. However a sort of rubber might swell depending
on the kind of solvent or frequency of use. If pressure in the system is not held,or,an abnormality is
shown the indicator ,please contact us.
•
Make sure that vacuum hoses are connected correctly ,to ｢pressure｣ and to｢load｣.

NOTE 1
The corrosion resistance above shows the case when samples are immersed in solvent or the
like. Since the product's gas-joints are exposed to low-concentrated steam that can not be
trapped by the condenser（cooler）, the joints are not corroded soon. However some sort of
rubber might swell depending on the kind of solvent, or, frequency of use. If pressure in the
system is not held or an abnormality is shown, please contact us.
NOTE 2
Since the pressure detection circuit which is constructed in the pressure sensor is exposed,
care should be taken to see that no liquid touch it. If the aspirator is shutdown without
leaking the vacuum, it may cause a back-flow and sensor parts may be damaged by water
from the aspirator's bath.

letters appear on the blind window) when breakages of the
pressure sensor occurred. The solenoid valve for control
shuts, the leak valve opens.
During Power Failure
In case of power failure, the leak valve opens, the atmosphere in the system of the rotary
evaporator is released, and the solenoid valve for control is shut. It prevents spout of organic
solvent in distillation, and back-flow of water from the aspirator.
After Power Failure
After power failure was repaired, the set mode is automatically switched to the fixed value
control. The indicator displays the set pressure blinking. The leak valve opens and the leak
lamp is on. The solenoid valve for control shuts. The fixed value control lamp blinks and the
set lamp is on.
