0. Introduction

0.1 Before using the vacuum pump

Thank you for purchasing our vacuum pump (hereinafter called “pump”). When you have received

the pump, check that the delivered pump is as per your order and that it has not been damaged in

transportation, etc.

In order to use the pump for as long as possible, read this instruction manual

thoroughly before performing installation, operation, inspection and

maintenance, and sufficiently understand the cautions for safety, the

specifications and operation methods of the pump.

No part of this instruction manual may be copied for use by a third party

without our permission.

0.2 Safety symbols

In this instruction manual and on warning labels attached to the pump, the following symbols

are used so that matters which must be strictly adhered to can be readily understood.

These symbols are divided as shown below.

When mishandled, there is an imminent danger of the operator suffering a fatal

accident or serious injury.

When mishandled, there is a possibility of the operator suffering a fatal

accident or serious injury.

When mishandled, there is a possibility of the operator suffering an injury

(light or medium injury) or of damage occurring to property.

When mishandled, there is a possibility of the pump being damaged or

malfunctioning.

0.3 Cautions for safety

This pump is for dry air or the dry nitrogen suck only.

Never allow people other than repair engineers to disassemble or repair the

pump. Failure to do so may result in ignition or malfunction, leading to injury

or electric shock.

Connect the earth wire correctly. It is set up that a dedicated earth leakage

breaker should be installed. If the earth wire is not connected, there is

a possibility of electric shock occurring in the case of a malfunction or

electrical leakage.

There is a risk of explosion. Never block the outlet or operate the pump with

equipment mounted at the outlet side which blocks the passage of gas.

Otherwise, the internal pump pressure increases causing the pump to explode,

the oil level gauge to protrude or the motor to be overloaded.

This pump is not resistant to pressure. The internal pump pressure is limited

to 0.03 MPa (gauge pressure).

It gets an electric shock touching the motor energizing part. Please work after

pulling out the power plug without fail when wires electricity is connected,

it checks, and it transfers it.

Do not use the pump in an explosive atmosphere. Failure to do so will result

in injury or fire.

When shipping from the factory, the motor is set for 100-120V class. Do not

operate with 200-240V power supply voltage. In order to operate with 200-240V

class, the changeover switch in the terminal box must be changed into 200-240V

class as shown in fig.3.4“Electric wiring.”

Danger

Warning

- 04 -

Never touch the rotating section of the motor, shaft or coupling while the

pump is in operation. Failure to do so will result in injury.

Never place combustible materials around the motor or pump. There is a risk

of fire.

Also, do not place objects which block ventilation around the motor. Abnormal

heat generation may result in burns or fire.

Do not touch the motor while the pump is in operation or when the pump is

still hot immediately after it stops. Touching it will result in burns.

Arrange wires correctly in accordance with the “Electrical Equipment

Technical Standard” and “Wiring Regulations.” Incorrect wiring may result

in fire.

If the pump ceases operation or malfunctions, turn off the power switch

immediately to prevent accidents, and ask the company from which you purchased

the pump or the manufacturer for inspection and repair.

Do not operate the pump without adding pump oil. If it is operated in an

oil-less condition, the pump will be damaged.

0.4 Acceptance and storage of the pump

0.4.1 Acceptance of the pump

Although the pump is delivered with great care, check the following after unpacking.

①The delivered pump is in accordance with your request.

②The specified accessories (enough pump oil to use the pump once; optional equipment) have

been provided.

③No parts have been damaged in transportation.

④Neither screws nor nuts have become loose nor were lost in transportation.

If there are any problems, contact the company from which you purchased the pump or the sales

department of the manufacturer.

0.4.2 Environmental conditions for storage, installation and operation

Since this pump is precisely engineered, ensure that the following conditions be satisfied during

storage, installation and operation.

①Ambient temperature, relative humidity: 7°C ~ 40°C, 85% RH or less

② Height above sea level during storage and installation: 1,000 m or less

③ Minimum required distances from the wall, 100mm

④ Other conditions for storage and operation

a）Free from corrosive and explosive gases

b）No condensation

c）Dust-free environment

d）Indoors

e）Do not place pumps on top of each other or place a pump on its side.

f）Not subject to direct sunlight

g）Far from heat sources

h）When you keep it for a long period of time, put pump oil into a pump and seal a inlet port

with a cap.

i）Don't keep it, where moisture is attracted.

Since the pump weighs as much as 16 kg, do not lift or transport it by yourself.

Doing so may cause an injury. Please wear safety shoes at the time of work.

Perform such work by two people as shown in 3.1 “Installation.”

Do not subject the pump to shocks or place the pump on its side. Doing so

may damage the pump.

For indoors use only.

0.5 Protective device

The pump is equipped with a single-phase 100-120 V (50/60 Hz) and 200-240 V (50/60 Hz)

motor.

This motor has a total of two overload protectors built in: one is of automatic reset type and the other

of manual reset type.

The automatic reset type thermal protector is intended to protect the motor when the pump is locked.

For details, refer to “4.6 Automatic Reset Type Thermal Protector.” The manual reset type thermal

protector is intended to protect the auxiliary coil.

For details, refer to “4.7 Manual Reset Type Thermal Protector.”

End-user has to make provisions for the installation of the over current protection of the power

circuit.

For the selection of an overload protector, refer to “3.4 Electric wiring.”

The automatic reset type thermal protector, one of the overload protectors in

this motor, will automatically reset itself after it has functioned.

This motor houses an automatic returning thermal protector, which may be

activated in case of trouble. The motor will restart automatically when the

temperature goes down to 78 ± 5℃.

If the thermal protector is activated, pulled out the power plug immediately

for safety reason.

Use the pump only at the rated voltage. Use at other than the rated voltage

will interfere with correct operation of the overload protector, and result

in the motor burning out, or fire.
