1. Fill Indicator Light: This green light will turn on
while the liquid is flowing from the spout.
2. Can Pressure Adjustment Knob: This knob allows
you to adjust the pressure inside your can. Turning
the knob counterclockwise will lower the pressure,
while turning it clockwise will increase the pressure.
This will typically only need to be adjusted when
starting a new filling session and during cleaning.
3. Pressure Gauge: Indicates the pressure inside the
can.
4. Fill Switch: The three (3) position fill switch turns
the fill cycle on (up position), turns the fill cycle off
but maintains a seal (center position), and releases
the can supporting foot rest after the can pressure
has been safely released (down position).
5. Top Off button This button allows you to add a
“shot” of beverage after the can has been released
from the stopper. This action will create an
additional volume of foam o which to place the lid
prior to seaming. This action is optional depending
on the desired amount of foam.
6. Pressure Release Switch: This switch is used to
manually control a valve to release the pressure in
the can. The switch should be in the down position
to start the fill sequence so the can will pressurize.
Once the fill is complete, set the Fill Toggle Switch
to the “Stop Fill” position and flip the Pressure
Release Switch to the up position to release the
pressure in the can.
7. Fill and Purge Spout: This spout is used for the gas
flush and liquid filling.
8. Level Sensor: This sensor sets the level at which the
flow will stop and be positioned up or down to
change the fill level to your specifications. Be
careful not to pull on the electrical wire.
9. Pressure Release Tube: This tube is vented to relieve
the pressure in your can.
10. Stopper: The stopper seals your can and helps to
control the level your can is filled to.
11. Pneumatic Ram: The pneumatic ram lifts the can
foot rest and is activated when the filling sequence
begins.
12. Can Foot Rest: These feet will hold your can
securely in place once the fill sequence is started.
Do not put your hands between the can and the foot
to prevent injury.

Operating Procedures
Step By Step
1. You will first want to unpack your filler from the
shipping box and spread the components out on a
large flat surface. Make sure that you also have the
following:
a. Pressurized CO2 tank with regulator and
connecting hosing (we recommend a wye as well,
see setup diagram for details).
b. Air compressor and 1/4" hosing
c. A small (.5 liter or so) catch container for
collecting vented liquid.
2. Place your filler on a flat surface where you plan to
can, ensuring that you have access to a standard wall
outlet or extension cord. Place the liquid and CO2
tanks, as well as the air compressor, nearby.
3. Attach the support legs by sliding the legs between
the enclosure and the rubber feet. The support legs
should extend forward, however if you extend them
out the back you need to clamp them to the flat
surface.
4. Begin by plugging the provided power cord into your
machine, and then plug it into the wall outlet. Flip the
Power Switch on the right side to turn on the filler.
Confirm the cleaning switches on the left side are in
the down position (Fill Mode).
5. Toggle the fill switches to the full up position (Start
Fill Position). Wait a few seconds to verify that the
green fill light illuminates.
6. Flip the fill switch back down to the Release Can
Position, the green fill light will turn off.
7. Once you are sure the filler is powering up properly,
turn off the power switch on the right side of filler.
8. Make sure the Pressure Relief Switch is in the off
position (Down).
The valves on the tanks should be off.
It is highly recommended that waster be used during the initial set up procedure. Water allows you to
familiarize yourself with the filler by removing most variables related to your product, for ease of operation,
and the reduction of waste of your product.

The valves on the tanks should be off for steps 9-11
9. Plug the hose from your liquid container into the port
marked “Inlet” on the left side of the machine using
one of the provided 3/8” barbed fittings.
See “Adjusting Pressure” on page 12.
10. Plug one end of the provided 4’ x 1/4” tube into the
port marked “Vent” on the left side of the machine,
and place the other end into your catch basin.
11. Plug your air compressor into the port marked “Air”
on the left side of the machine using one of the
provided 1/4” barbed fittings.
See “Adjusting Pressure” on page 12.
12. Plug your CO2 tank into the port marked “CO2” on
the left side of the machine using one of the
provided 1/4” barbed fittings.
13. Once you are sure that all components are plugged
in correctly, you can open the valves on your tanks
and turn on the air compressor.
14. Turn on your machine by flipping the power switch
on the right side of your machine so that is it lit up.
15. You are now ready to place a can on your machine.
While pressing down on the Can Foot Rest, place a
can on the can locator and lift the foot so the can
slides snuggly over the stopper.
16. Make sure the Pressure Release Switch is in the off
position (DOWN).
Note: A clear can has been provided to help with the
initial setup, steps 17-20. Setup is done for each spout
individually.
Always keep your hands clear of the can and foot
rest during step 17.
17. Flip the Fill Switch to the full up position. The filler
will purge the can for a few seconds, after which
the Can Foot Rest will immediately lift the can into
a sealing position against the stopper and pressurize
the can.
18. After the purge and can pressurization, the fill light
will come on and liquid begins to flow into the can.
If no flow is visible, then the Pressure Relief needs
adjustment.
See “Adjusting Pressure” on page 12.
Repeat steps 15 –18 for the other spouts.
19. Once the green fill light deactivates, put the Fill
Toggle Switch to the middle position (do not flip to
the full down position), then you can turn on the
Pressure Release Switch (UP).
20. Hold the can with one hand and flip the Fill Toggle
Switch to the full down position to release air in the
pneumatic ram and remove the can by pushing
down on the foot rest. At this stage, you may choose
to press the Top Off Button to inject a “shot” of
beverage to create an additional volume of foam on
which to place the lid prior to seaming.
Note: You can use the silicone surgical tubing included
to fill from the bottom of the can or even halfway to the
bottom.
Congratulations,
you have now filled your first can using
the XF4500C Counter-Pressure Filling System!

Adjusting Pressures
It is the pressure differential between keg/brite tank pressure and can pressure that determines the rate of filling,
amount of foam and retention of CO2 in your product. Therefore, adjusting either or both pressures can result in a
more favorable fill.
1. Each spout must have its can pressure set individually.
2. The pressures during filling are adjusted to obtain a quick rate of filling with limited foaming. Excessive foaming
will trigger the fill sensors and stop filling prematurely. The can will begin filling again as the foam settles, but
this significantly slows down the filling rate.
3. Typical maximum inlet pressures from a keg or brite tank are 30 psi and 15 psi, respectively.
4. Turning the Can Pressure Knob counterclockwise will start venting the pressure in the can and allow product to
flow into the can. The more the can vents, the quicker it will fill, but foam can start to develop. The Can Pressure
Knob can be adjusted to achieve an acceptable rate of fill as evidenced by the visual presence of limited foaming.
5. The inlet pressures can also be adjusted in conjunction with can pressures to change the filling rate and foaming
characteristics.

If at any time you have issues with the setup or adjustment of your XF4500C can filling machine, or any other
questions about filling your product, please contact us at the number listed at the front of this manual. We are always
happy to assist you.

Troubleshooting
Premature Shut Off
The XF4500C is a Level Fill Machine, meaning when liquid
touches a spout and probe, it will automatically shut off. If
moisture is allowed to collect between the spout and the probe,
the filler will shut off prematurely, stopping the fill or not
allowing the fill to begin at all, which is characterized by the
green LED fill indicator light to flash quickly and stay off as the
machine senses a full can is in place.
Dry the area between the spout and the probe with a clean
towel or use the compressor to air dry. Once completely dry, the
fill will resume. Isopropyl alcohol is very good for cleaning and
is fast drying.
Excessive Foaming
Excessive foaming is usually the result to the keg pressure not
being high enough, too high fluid temperature, or the indicated
pressure on the filler gauge is too low. The difference between
the keg pressure and the counter pressure indicated on the filler
should be around 5 psi. The higher the pressure, the more CO2
will stay in solution.
Turning the Can Pressure Adjustment Knob clockwise will
increase the can pressure and reduce foaming. The higher the can
pressure and lower the temperature, the more CO2 will stay in
solution.

Cleaning and Sanitizing
Cleaning your XpressFill is quick and easy, and is the single most important maintenance you can administer to
ensure long life and solid performance from your filler. Please use extreme caution when using any cleaning
product.
For general cleaning, we highly recommend a product called PBW by Five Star Chemicals. It is safe, fast, and
effective, and our customers have been happy with the results. To clean your XpressFill, begin by flushing your
filler with 2 gallons of plain warm (not boiling) water from a pressurized keg, which is pressurized with air. Follow
that with a 3-gallon mix of PBW cleaner, and let the PBW sit inside your filler for a few minutes in order to do its
cleaning job. Follow the cleaning with a sanitizer.
For sanitizing, we recommend Saniclean, from the same manufacturer. Saniclean has low foaming
characteristics, is highly effective, and completely food grade if diluted correctly per the manufacturer’s instructions.
Use the sanitizer with about 3 gallons of water, and follow the steps according to the manufacturer’s instructions.
After sanitizing, flush your filler with 2 gallons of warm water. Before storing your XpressFill filler, make sure you
get all water out of the flow path. Allow to run until pressurized keg with cleaning solution is empty and runs dry,
blowing the remaining water out of the filler vent.
See step-by-step instructions and diagrams on the following pages.
