Page 4: Cautions For Safety
0.3 Cautions for safety Danger When toxic or flammable gases are exhausted from the pump, they may leak not only from the pump outlet but also from the pump unit itself. Take proper measures suitable for the type of gas. Danger After the pump has been used for exhausting toxic gasses, not only the pump itself but also vacuum pump oil (hereinafter called “pump oil”) get toxic. - Page 5 Warning Do not use the pump in an explosive atmosphere. Failure to do so will result in injury or fire. Caution Do not insert fingers or objects into the opening of the motor. Doing so may result in electric shock, injury, or fire. Caution Never touch the rotating section of the motor, shaft or coupling while the pump is in operation.

Page 16: Electric Wiring
3.4 Electric wiring (1) Plug the power cord or the motor lead to a power compatible with the motor rating. (2) This pump is wired for use on 100 V single-phase power as standard. (3) If the pump motor is changed with a motor for use on three phase power, turn ON the power switch after plugging the power cord to the terminal block of the motor and check if the motor rotates counterclockwise as viewed from the back of the motor. - Page 17 Warning It will cause a serious damage or movement failure to the motor in case of impressing the inverter controlled pressure is given towards the motor itself. Please carefully be noted and do not take the above action. Warning Before connecting wires, turn off the power switch. Never perform wiring with the power supplied as an electric shock will occur.

Page 18: 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 19: 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. 4). Caution ① The motor and pump become hot (temperature increase under non-load operation: 40℃, temperature increase under high-load operation: 80℃) during operation of the pump. -
Page 20: Operation In Cold Climates
Caution The motor and pump become hot (temperature increase under non-load operation: 40 ℃ , temperature increase under high-load operation: 80 ℃ ) 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 21: Gas Ballast Valve
4.6 Gas ballast valve The pump is equipped with a gas ballast valve in order to evacuate vapor and condensable gases such as solvent vapor. Evacuated condensable gas that liquefies in the compression and pressurization processes of the pump is mixed with the pump oil and starts circulating through the pump together with the oil. In such a case, the same effect as when oil of a high steam pressure is used is produced, and the ultimate pressure of the pump increases. -
Page 22: Installation Of The Oil Mist Trap (Option)
4.7 Installation of the oil mist trap (Option) An oil mist trap can be installed in order to remove oil mist from the pump. As such an oil mist trap, models OMT-050A and OMS-050 are available. Remove the standard exhaust port from the exhaust port of the pump and install an oil mist trap instead. -
Page 23: 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. -
