PULSE (Optional): Generally it is recommended to operate Merlin in the Auto Filling
program with the PULSE button off. When the PULSE button is on, a rapid pulse of CO
2
is blown into the bottles after they are filled. This pulse creates seed bubbles in the beer
and causes foaming prior to capping the bottles. The Low Pressure adjustment described
above is the amount of pressure left in the bottles when the pulse takes place. The
intensity of the pulse is controlled using the horizontal slide bar labeled “Pulse Intensity”.
The pulse intensity is adjustable from 3-12, with 12 being the highest level available. If
the PULSE is turned off the machine uses the Low Pressure setting as the pressure in the
bottles when the filling heads will be raised. The PULSE can be turned off and on during
the automatic fill program as needed.
NOTE: The first bottles off the bottling machine will contain sanitizing solution. Be
sure to set those bottles aside so they don't get mixed up with bottles containing
beer.

The bottle fill rate is adjusted by using the off-gas flow regulator valve located just below
and to the left of the control panel. Closing this valve slows the flow of liquid into the
bottle, while opening the regulator increases the rate of fill. The fill rate should be slow
enough that the liquid does not foam while the bottles are filling.
7.
Once the machine is operating, you can adjust the fill sensitivity as needed to get
consistent fills, and the Low Pressure as needed to control foaming along with turning the
PULSE on or off.
8.
To pause the machine at any time during automatic filling, press the Auto Filling button
and the machine will stop in the safe shut down configuration, releasing pressure from the
bottles with the filling head down. When the Reset button is pressed the machine will
reset and the filling heads will go up. Once the machine has been reset you can start
another Auto Filling operation by pressing that button or press the “Main” button with the
wizards image to go to the main menu.
