Page 19: Installation
Ensure that the Microvac pump is suitable for the application. Refer to the Edwards guidelines on vacuum pump and vacuum system safety (see the associated publications at the end of the Contents list at the front of this manual).
Page 20: System Design Considerations
If the unit will be stored for a period of time before commissioning, follow the same procedure. Page 14 © Edwards Limited 2011. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 21: Inlet Piping
(See Figure 10). A full-opening high vacuum valve is recommended to facilitate start-up and for checking the pump blank off pressure. © Edwards Limited 2011. All rights reserved. Page 15 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 22: Vacuum Access Port Locations
Tygon should be used for a flexible connection. The gauge should be located approximately 610 mm (24.0 inch) above the port to prevent oil from entering the gauge. Page 16 © Edwards Limited 2011. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 23: Exhaust Piping
138 mbar (2 psig). The pumps emit tiny oil droplets into the exhaust of the pump. Edwards recommends the use of exhaust filters to prevent these droplets from accumulating in the exhaust piping of the system or where the piping terminates. The oil and condensables will coalesce inside the piping and return to the pump reservoir or be collected inside the filter housing.
Page 24: Electrical Connections
Connect the motor so that the pump shaft rotates clockwise when viewed from the drive end. See Section 4.1 pre-start check procedures. Page 18 © Edwards Limited 2011. All rights reserved. Edwards and the Edwards logo are trademarks of Edwards Limited.

71°C (140-160°F). Oil temperature kits are available that automatically control the water flow to maintain the proper oil temperature (Contact Edwards for additional information). If the pump is located outside a building and subjected to freezing temperatures, the pump water jacket should be drained or filled with anti-freeze.

212-J; and, 45 liters (12 gallons) for the 412-J. Before connecting the suction manifold, slowly rotate the pump through two (2) revolutions. This will distribute the oil throughout the pump interior. © Edwards Limited 2011. All rights reserved. Page 21 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 29: Operation
2. Ensure the equipment being evacuated is properly cleaned and all vacuum breaks are closed. 3. Depress the START button and check the solenoid valve for proper operation. 4. Open the pump inlet valve. © Edwards Limited 2011. All rights reserved. Page 23 Edwards and the Edwards logo are trademarks of Edwards Limited.
Page 30: Gas Ballast Operation
If desired, a solenoid valve attached to the gas ballast inlet and electrically connected to the motor leads can be used to turn off the gas ballast automatically on pump shutdown. Contact Edwards for additional information.
Page 31: Pump Stop
Note: Edwards offers a closed type oil mist separator that will eliminate exhaust oil smog but still requires exhausting to outside. Contact a Edwards representative for information. If the pump has been shut down for an extended period of time, it will be necessary to turn the pump over at least two (2) revolutions by momentarily jogging before starting to insure the free movement of parts.

Page 35: Oil Change
Review the process contaminants and select proper personal protective equipment (PPE) to protect against media contact. Using the drain valve, drain the oil into a suitable container for disposal. Use only Edwards recommended oils when refilling the pump. Refer to Section 2 for fluid type and quantities.
Page 36: Belt Maintenance
Use an O-ring pick or suitable tool to pull out the gas ballast check valve. Replace the valve if the spring is damaged or broken. Reinstall the stem valve. Check the pump and system for potential hazardous conditions. Restore energy sources. Page 30 © Edwards Limited 2011. All rights reserved.
