The use of other oils is not authorized. <br /> 1. Ensure that oil is added until a small amount of oil just begins to overflow from <br /> the port 5B located on the exhaust box. Please reference the attached drawing of <br /> the vacuum pump exhaust box. Add oil from port 5, located on the top of the <br /> vacuum pump exhaust box. <br /> 2. If alarm persists after oil is added, change the setting of the MIN/MAX limit <br /> switch located within the Oil Level Sensor(This switch is found by unscrewing <br /> the white cap on the oil level sensor). After changing the setting, did the oil level <br /> alarm light go off? If yes, use the new setting. If no, oil level sensor or field <br /> wiring is faulty. <br /> 23 <br />
