The Merlin control panel also displays temperature in the product manifold located at the
top of the machine. This temperature display simply lets the operator observe the incoming
temperature of the product and can be used to help with determining proper pressures in the
liquid tank.

A button labeled “Liquid psi Control” is located in the upper right hand portion of the
display. This button turns on and off the controls to adjust CO2 dispensing pressure in the
head space of the tank based on liquid manifold pressure at the machine. This function is
optional and intended to help resolve dispensing pressure drops that can occur using manual
style regulators. To utilize this feature, an independent CO2 source, different from the one
used for the bottling machine, is connected to the
control valve inlet (see photo). The inlet pressure
should be set at 30-35psi from the CO2 source. A
hose will need to be connected between the
control valve and head space of the dispensing
tank.
How “Liquid psi Control” (LpC) works, is when
connected to a CO2 source and the head space of
the dispensing tank and the system is activated by
pressing the “Liquid psi Control” button. The
computer initially records the static liquid pressure
at the manifold and displays that pressure as the
set point above the adjusting arrow keys. Using
the arrow keys you can adjust this set point up or
down as needed. Each cycle, before the product
valve opens the computer, will sample the
manifold pressure and turn the CO2 control valve
on or off as needed.
NOTE: This system is limited to a maximum control pressure of 14.9 psi and only operates
when the filling process is running. It does not function when the machine is paused.

Press the RESET button on the operator interface and the message display should read
“System is Reset”. Press Auto Filling to start the machine in its automatic filling and
capping mode. The message display will display “Automatic Filling”, the RUN light will be
illuminated and the Auto Filling button will change from red to green. To adjust the Low
Pressure and Fill Sensor simply move the slide bars to the desired amount. Adjusting the
Fill Sensor to a higher value makes it less sensitive and a lower value makes it more
sensitive.

Evac (Optional): When turned on, this button will cause the machine to do the first
evacuation of the bottles, then put CO2 into the bottles, then evacuate the bottles a second
time before counter pressure of the bottles takes place. Using this feature slows
production rates slightly, but ensures the lowest air pickup to the product.
