Warning

Do not use the unit in an area where there is flammable or explosive gas.

Never use the unit in an area where there is flammable or explosive gas. The unit is not explosionproof. An arc may be generated when the power switch is turned ON or OFF, and fire/explosion may result.

Always ground the unit.

Connect VR100’s power plug to a receptacle with grounding connectors.

Do not forget to ground VR100, to protect you and the unit from electrical shock in case of power surge. Choose a receptacle with grounding connectors as often as possible.

Do not connect the grounding wire to a gas pipe, or by means of a lightning rod or telephone line. A fire or electrical shock will occur.

100V receptacle with grounding terminals

Power plug

If only bipolar receptacles are available for VR100, connect an optional grounding adapter to VR100’s power plug. Check the polarity of the receptacle before connecting the adapter to the receptacle. Connect the adapter’s grounding wire (green) to a grounding terminal to the power supply. Contact our sales representative in your vicinity or our service center for additional information or assistance.

Choose a correct power distribution board or receptacle.

Choose a correct power distribution board or receptacle that meets VR100’s rated electric capacity.

Electric capacity : AC100 V, 1A

Do not connect VR100 to an outlet that differs from the above specifications because a fire or electrical shock will occur.

Install on a level area.

Do not installation VR100 on a non level surface. This will cause hazards to the operator and create problems during actual operation.

Choose a proper place for installation.

Do not install VR100 in a place where:

Flammable gas or corrosive gas is generated.

Ambient temperature exceeds 35° C, also bellow 5° C.

Ambient temperature fluctuates violently.

There is direct sunlight.

There is excessive humidity and dust.

There is constant vibrations.

• Keep the clearance over 15cm around VR100.

Caution

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 supplied appropriate power and voltage. If the power 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. Connect the pipes correctly in accordance with each indication of them.

Handling Precautions

Warning

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 while 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.

Aspirator Shutdown

The device must be stopped before you stop the aspirator. If not,backflow ,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 .
