EtOH Pro

DOC 74-00011 Rev A
Overview
• Important - Prior to First Use: Slightly lift the rubber plug at the top of the gauge to allow the
internal pressure to equalize. DO NOT push in or fully remove plug.
• Important - Do not rotate/twist Gauge Assembly coming up from lid. The Gauge Assembly is able to
rotate slightly, but excessive rotation could lead to leaks over time.
- Designed to fit the EtOH Pro Kettle.
- Uses the EtOH Pro’s Purge Mode.
- Requires an external vacuum pump capable of providing high vacuum.
- Hose barb is designed for 5/16” ID vacuum tubing.
- The Vacuum Pump must be plugged into a normal power outlet. The switched outlet on the back of the
EtOH Pro is not used for Purge Mode.

- Oil should be on a non-stick silicone mat placed at bottom of the Kettle.
- Plug the kettle into the EtOH Pro, verify the machine is turned on via the switch in the rear and that the dial
is set to Purge Mode.
- Attach the vacuum tubing to the Barbed Fitting. Attach the other end of the tubing to the vacuum pump.
- Place the lid on the Kettle and press the green Start button on the EtOH Pro to start Purge Mode.
- Make sure the Vacuum Valve is in open position and the Vent Valve is in the closed position.
- Turn on the Vacuum Pump and keep it running until you reach the maximum vacuum your pump will allow.
(Make note of the maximum vacuum level for future reference.)
- Close the Vacuum Valve. Turn off the Vacuum Pump.
- After a couple of minutes verify the Kettle is warming up by feeling the base of the Kettle.
- Note: The base of the kettle will never be hot to the touch.
- If the base of the kettle does not feel warm see the steps in the Troubleshooting section.
- Appropriate vacuum purge time and vacuum level varies on a wide range of factors. Experiment for your
best results.
- As vacuum level drops, you can open vacuum valve, pull additional vacuum again by turning on the pump,
then close valve and turn off pump.
- When the vacuum level no longer drops after an extended time your purge is completed.
- Open the Vent Valve, then Vacuum Valve, and remove the Purge Lid.

- Incorrect Gauge Reading
- At default, the needle on vacuum gauge should read 0. If it is not, equalize the pressure by lifting the
rubber plug to vent the gauge.
- Equalizing the pressure in the gauge can be done at any time. Venting the gauge plug is useful to
verify the gauge is reading correctly.
- Vacuum Dropping
- If the vacuum is dropping quickly check that all sealing surfaces are clean and free of debris.
- Some vacuum loss is normal to the process.
- Vacuum drop may be due to the internal pressure changes in the gauge. Vent gauge to check.
- Kettle Not Heating
- Verify the kettle is fully inserted by firmly pushing the kettle forward into the machine.
- Check for a rise in temperature by feeling the base of the kettle. The kettle may take a couple minutes
to feel warm to the touch.
- The kettle may be safely pulled out and reinserted while Purge Mode is running.
