Page 7: Cautions For Safety
0.3 Cautions for safety Danger This pump is for dry air or the dry nitrogen suck only. Warning 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. - Page 8 Warning Do not use the pump in an explosive atmosphere. Failure to do so will result in injury or fire. Warning 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“Changing the voltage class.”...
- Page 9 Caution 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. Note Do not operate the pump without adding pump oil. If it is operated in an oil-less condition, the pump will be damaged.

Page 20: Installation
3. Installation 3.1 Installation The pump should be installed on a level surface in a location with minimal dust, dirt and humidity and be arranged with consideration given to ease of installation, removal, inspection and cleaning. Particular attention should be paid to the ambient temperature when building the pump into equipment. -
Page 21: Lubrication
3.2 Lubrication Remove the lubrication plug from the lubrication port, and add the pump oil which has been delivered together with the pump or the pump oil specified by us (SMR-100) up to the range marked with the line on the oil level gauge. When making the first lubrication, add oil near to the upper oil level limit shown on the oil level gauge. -
Page 22: Vacuum Piping
3.3 Vacuum piping (1) Before connecting the pipe to the pump, clean the inner walls of the vacuum chamber, piping and vacuum valve to completely eliminate moisture, fine particles, dust, dirt and rust. Note If fine particles, dust or dirt, etc are evacuated, the pump may malfunction. If moisture is evacuated, not only does the ultimate pressure increase but also the inside of the pump becomes rusty causing the pump to malfunction. -
Page 23: Changing The Voltage Class
3.4 Changing the voltage class Voltage class of power sources is changed by the changeover switch in the terminal box. 100-120V class and 200-240V class are prepared. When shipping from the factory, the Voltage class is set for 100-120V class. Fig.6. -

Page 27: Operation
4. Operation 4.1 Cautions for operation Warning 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 pump internal pressure increases causing the pump to explode, the oil level gauge to protrude or the motor to be overloaded. -
Page 28: Start Of Operation
4.2 Start of operation To start operation, close leak valve (B), open vacuum valve (A) to the inlet port, and turn on the power switch. Then the pump starts beings to exhaust (see Fig. 5). Caution ① The motor and pump become hot (temperature increase under non-load operation: 25K, temperature increase under high-load operation: 75K) during operation of the pump. -
Page 29: Operation In Cold Climates
Caution The motor and pump become hot (temperature increase under non-load operation: 25K, temperature increase under high-load operation: 75K) during operation. There is a risk of burns. Never touch the motor or pump until they have cooled down completely after the pump is stopped. 4.4 Operation in cold climates In winter-season, when operating the pump in cold environment , it will be difficult to start up the pump. -
Page 30: Thermal Protector
4.6 Thermal protector Auto reset thermal protector is incorporated in the motor in order to interrupt the power circuit of the motor and prevent damage to the motor when an over current flows through the motor due to a stop in rotation or overload resulting from the pump malfunctioning during operation.

Page 31: Installation Of The Oil Mist Trap (Option)
Caution The vacuum pump becomes hot (temperature increase under non-load operation: 25K, temperature increase under high-load operation: 75K) during operation. Do not touch any section other than the valve while the gas ballast valve is in operation. When starting operation, be sure to close the gas ballast valve. Note If the gas ballast valve is left open without condensable gas being exhausted, the pump oil scatters, power is lost, or the ultimate pressure increases. -
Page 32: Pump Performance
5. Pump Performance 5.1 Ultimate pressure The term “ultimate pressure” as employed in the catalogue and in this manual is defined as “the minimum pressure obtained by the pump without the introduction of gas from the pump inlet (i.e. the non-load condition).” For this pump, measurement is performed using the specified pump oil with only a Pirani vacuum gauge installed at the pump inlet port. -
