2. Use electric source cord and ground cord of over 2mm² (over rated 18A/single phase and 15A/three phase) for ISP-500B. If not, it can cause bodily injury or fire due to electricity. 3. Firmly fit proper round crimp-style terminal to electric cord with application device and connect to motor terminal.

Check turning direction after wiring Turning direction of pump is clockwise viewed form motor side. Operate pump with inlet opened, and check that air comes out from outlet. If it turns counterclockwise in case of three-phase, reverse any two phase wires in electric source connection. If you fit pump to vacuum system and switch pump ON-OFF with remote control, first check pump itself about turning direction and then fit it to vacuum system.

• Use isolation valve (we recommend the use of leak valve also) between vacuum chamber and inlet (NW40 for ISP-500B). These valves (isolation valve and leak valve) are used to prevent the drawback of debris attached to the inside of vacuum pump into the vacuum chamber during start-up or shut-down.
6.0 Operation Be sure to use the procedure below to start up or shut down the pump. If it takes time to reach ultimate pressure of pump during initial operation (also operation after pump has not been used for a long time) Close inlet, and continue operation for 6 –...

6.1 Start-up 1. Close isolation valve in order to prevent the drawback of debris attached to the inside of vacuum pump into vacuum chamber. (Open leak valve when using leak valve). 2. Switch vacuum pump on. 3. Check start-up of vacuum pump and open isolation valve (close leak valve when using leak valve) and pump the vacuum chamber.

6.3 Pumping vapor (Air Flush operation) This pump is equipped with air flush port. Before pumping vapor, fully read precautions below and understand the contents. Purpose of air flush Pumping of humid gas by vacuum pump can cause condensed moisture to remain in pump.
Page 22
Continuous pumping of humid gas When pumping vacuum chamber while humidity in chamber is high, moisture volume drawn into pump differs according to temperature and pressure in chamber. Air Flush operation When pumping chamber containing gas with to pump humid gas humidity of over 60% RH be sure to open air flush port and operate pump.

6.4.1 Finish Air Flush operation To finish air flush operation, remove air flush filter of air flush port. Lightly tighten plug with spanner. Air Flush Filter (used during air flush operation) 6.4.2 Restart Air Flush operation To restart air flush operation, remove plug of air flush port and screw it into housing of air flush port.
7.0 Maintenance and Inspection Neglect of maintenance and inspection can cause poor performance and pump failure. In order to remove debris accumulated in vacuum pump, operate pump several times for 3 ~ 5 seconds (once a day) while drawing atmospheric air. Observe maintenance and inspection Be careful about high temperature Do the maintenance after the pump becomes cool...
