Operating instructions:

Start: 1. Close all the valves. 2. Flip the switch on the power strip 3. Push “Stop” membrane switch on the turbo pump controller if the mechanical pump will start. 4. Connect the volume you want to evacuate to the intake flange. 5. Open the vacuum valve. 6. Push “Start” membrane switch on the turbo controller. 7. Mechanical and turbo pumps will start, wait till turbo reach 56000 RPM, message “Normal operation” will appear on the controller. 8. Wait till the pressure on the thermocouple will drop to 1E-3 Torr. 9. Push “Emission” membrane switch on the Sentorr controller, it could take a few minutes to ignite the cold cathode gauge. 10. Wait for the desired vacuum.

Stop: 1. Keep the vacuum valve closed if you want your volume to stay under vacuum, leave it open if you don’t. 2. Push “Stop” membrane switch on the turbo controller, mechanical pump will stop, turbo controller will stop supplying power to the turbo pump, the vent valve will open air to the turbo, it will slow down and quickly stop.

What NOT to do: 1. Never open the vacuum valve if your volume is at atmospheric pressure and turbo pump is running, in-rush air will hit the turbo pump blades and it will be destroyed. 2. Do not open vent valve with the yellow handle if the main vacuum valve is open and turbo is running. 3. Never pump down oily or volumes with particulates, it can damage the turbo and mechanical pumps and will require vacuum system disassembling and cleaning. 4. Do not pump down glass objects, adapter on the turbo intake flange did not allow screen installation, if glass will be broken, it will be sucked into the turbo and destroy it.

Pumping station can evacuate only small volumes when starting from the atmospheric pressure, for bigger volumes auxiliary mechanical pump is required, otherwise turbo pump will overheat from the long start.

Turbo will require water cooling if operated in 1E-4 Torr range for the long time.
