- Open the main water supply valve (green pipe) located on the east side of the heat exchanger.
- Log on to the computer using the user id of lab and the password of seniorlabmeb3520
- Double-click on the Icon located on the desktop labeled (IO Display Runtime Pro). This will start the Opto program.
- Click on the start button on the opening window.
- Open the Process valve, Steam Valve and the Coolant Valve from Opto control.

- Open the green ball valve that controls the pump output to tank. This will insure that the pump will not deadhead.
- Set the tank drain valves to allow the feed tank to fill. Do Not Leave The Equipment Unattended!
- Once the feed tank has approximately 5 gallons in it you may turn on the feed pump using the power switch (Double Pipe Heat Exchanger) located on the wall east of the heat exchanger.
- Adjust the valves to the desired setting being careful not to deadhead the pump.
