pertinent safety procedures.
IMPORTANT SAFETY PRECAUTIONS
The type of vessel described in this manual
holds and dispenses carbon dioxide (CO2)
gas under pressure. All persons using this
equipment must read and understand the
operation and safety information contained in
this manual.
FIRST AID AND EMERGENCY ACTION
If inhaled:
•

•
WARNINGS
CO2 gas is a colorless, odorless, tasteless gas that
displaces oxygen and will not support life. The gas
is difficult to detect without special equipment.
Avoid breathing or contacting CO2 in gas, liquid
or solid form. Exposure to concentrations of less
than 5% for less than 15 minutes can cause physical
symptoms including unconsciousness, injuries or death.
Even low concentrations of CO2 can cause:
In case of frostbite:
• End exposure immediately.
• Do not rub or pour water on the affected area.
• Get immediate medical attention.
Rescue:
• Do not attempt a rescue in areas of high CO2
concentrations without proper life-support or
rescue equipment. (Avoid being the next victim.)
• Thoroughly ventilate areas of possible high
CO2 concentration before entering them.
• Dizziness, headaches, nausea or disorientation
• Increased respiration or heart rate
• Shortness of breath or rapid suffocation.
CO2 is heavier than air and can collect in low areas
such as basements, stairwells, and confined spaces.
Avoid entry into areas where CO2 leaks or high
concentrations of CO2 are suspected. Enter those areas with
caution only after they have been thoroughly ventilated.
In case of spills or leaks:
• Evacuate all personnel immediately from
affected areas.
• Thoroughly ventilate the area of the spill or
leak before entering.
• CO2 is heavier than air. It displaces oxygen
and will collect in low or confined areas.
Whenever the vessel is inside a building it’s safety
relief circuit must be connected to an outdoor vent
typically in the fill box. The fill box and/or vent
must never be located in or above any belowground spaces or stairwells. The vessel must not
block emergency exits, aisles, fire suppression
equipment or utility boxes or accesses. CO2 lines
or hoses must be located away from traffic areas
and heat sources and must be protected from
potential causes of damage. All connections,
lines, and components must be leak-free.

General Description
System Overview
The Carbo-Mizer carbon dioxide (CO2) system
for McDonald’s restaurants is designed for lowpressure storage and supply of carbon dioxide gas
for beverage carbonation. The system consists of
three primary elements: the CO2 storage vessel, an
outdoor fill box, and fill and vent lines.
Syrup
Gas Supply
Vent Circuit
Fill Circuit
Shut-Down
Circuit
Storage Vessel
The vessel is the first of the three primary elements
in the Carbo-Mizer storage system. It consists
of an inner vessel and an outer vessel, much like
a ThermosTM bottle. The space between the two
vessels contains a nearly perfect vacuum and a
special insulation. The vacuum and insulation
minimize the entry of unwanted heat into the
liquid CO2 stored in the inner vessel. When CO2
gas is needed it is withdrawn from the top (gas
space) of the inner vessel and dispensed to the
beverage system or other use point.
Carbonator
Gas Supply
Pressure
Building Circuit
Vessel Plumbing
Plumbing components on the vessel perform
five functions:
• Liquid CO2 fill
• Gas supply (Gas Delivery)
• Pressure control (Pressure Building)
• Safety (Vent/Relief)
• Pressure and contents measurement (Gauges)
The fill circuit allows liquid CO2 to be transferred
into the vessel during the delivery process. The gas
supply circuit dispenses CO2 gas to the beverage
and syrup systems. A pressure control circuit
maintains the internal vessel pressure needed to
supply CO2. The vent/relief circuit allows excess
pressure to safely exit the vessel and the building.
A contents and pressure gauge indicate the status of
the CO2 inside the vessel.

by sensing the internal vessel pressure. When that
pressure drops below the regulator’s set point (factory
set at 140 psi), the regulator opens allowing liquid
CO2 to flow into the vaporizer where it transforms to
gas and re-pressurizes the vessel. When the internal
pressure reaches the regulator’s set point, the
regulator closes and the flow of liquid CO2 stops.
Fill Circuit
The stationary fill circuit consists of a brass fill
fitting in the fill box, a fill hose, and a valve on
the vessel. Liquid CO2 is transferred into the
vessel through the brass fill box fitting and the
fill hose. The shut-off valve on the vessel’s fill
port allows service to be performed on the fillbox / fill-line segment of the fill circuit without
emptying the vessel. A portable vessel’s fill
circuit consists of a brass fill fitting and bracket
secured to the top of the vessel.
During the pressure building process cold liquid
carbon dioxide flows through a vaporizer coil that
is attached to the inside wall of the outer vessel.
This cools the outside of the vessel and causes a
condensation or frost ring to form near the bottom
of the vessel. The appearance of a frost ring is
normal when CO2 is being used . However, if
frost is present after some time when no CO2 gas
has been used, such as in the morning before the
start of operations, this may indicate a CO2 leak in
a line or the beverage or other use-point system.
Gas Use Circuit
The gas-use circuit supplies gas to the carbonator
and syrup systems. CO2 gas is withdrawn from
the gas space above the liquid CO2 that is stored in
the vessel. When demanded at either use point,
CO2 gas passes through the shut-down ciecuit
valve and into the respective final line regulator.
Safety Vent Circuit
The final line regulators control gas flow to the
beverage or syrup systems. The factory setting
on the carbonator gas supply regulator is 90 psi
but the pressure may be adjusted to suit the needs
of the application. This regulator is commonly
set between 90 psi and 115 psi for soft drinks.
Secondary pressure regulators may be added
‘downstream’ for applications such as bag-in-thebox or diet systems. The syrup gas use regulator
is set at 65 psi for the syrup system. Consult with
the use-point equipment manufacturer for the
correct regulator and pressure setting.
The inner pressure vessel of this storage system
is designed to meet or exceed the ASME Section
VIII, Division 1 pressure vessel code. The code
dictates that the vessel be protected against excess
pressure by a safety relief valve. Chart uses two
safety relief valves for added safety. The vessel’s
safety circuit is comprised of an ASME relief
valve set at 300 psig and an additional relief valve
set at 450 psig. The relief valves must always be
vented outdoors by a vent tube, usually through
the fill box, to prevent potential concentration of
CO2 within the building. The 300 psig relief valve
may open during CO2 deliveries or when CO2 is
not being used regularly.
Pressure Control Circuit
The pressure control circuit, also called the
“pressure building” or “PB” circuit, maintains the
internal operating pressure of the vessel. Adequate
vessel pressure is needed for supplying CO2 gas and
for preventing the stored liquid carbon dioxide from
changing to ‘dry ice,’ the solid form of CO2.
Pressure And Contents Gauges
The vessel pressure gauge measures the pressure
in the top (gas space) of the inner vessel.
This pressure can normally range between 140 psig
and 300 psig but the typical vessel operating
pressure is 140 to 165 psig.
The pressure building circuit activates to rebuild
internal vessel pressure as gas is drawn from the
vessel and its pressure drops below a set level.
A regulator controls the pressure building process

The vessel contents gauge measures the
approximate level of CO2 liquid in the vessel.
The movement of a magnetic rod “floating” in
3
the liquid CO2 causes the needle on the contents
gauge to move as the level of liquid CO2 in the
vessel changes.
The Bulk CO2 Supplier
The bulk CO2 supplier is also an important part of
the system. Most CO2 suppliers not only provide
timely delivery of CO2 but also install and service
the system. For service, parts, information,
emergency CO2 delivery, or other CO2 related
assistance, contact the local Chart authorized
CO2 supplier. A place has been designated on
page 17 of this manual to record the name and
phone number of the CO2 supplier and other
important service contacts.
NOTE: Because the float-rod does not actually
float on the surface of the liquid CO2 it does not
provide a precise measurement of liquid CO2 level.
CO2 Fill Box
The stainless steel CO2 fill box is the second major
element in a typical bulk CO2 storage system.
The purpose of the fill box is to provide a
convenient point to fill the storage vessel, to make
connections for syrup delivery, and to vent excess
pressure from the vessel out of the building.
The fill box has a brass fill fitting, a connection for
the safety relief vent circuit, a safety snap connection
point, and a lockable door. Two standard types of
fill boxes are available; a surface-mount model and a
flush-mount model.
Fill boxes must be mounted outside the building
where they are easily accessible to the CO2
supplier and where they can safely vent excess
CO2 pressure outdoors. When a vessel is used as a
portable system, a vessel-mounted brass fill fitting
and an alternative safety relief vent line are used
instead of the fill box.
Fill Hose And Vent Line
The third major element of a stationary bulk CO2
system is comprised of a fill hose and vent line.
These lines join the CO2 storage vessel with the
outdoor fill box. The fill hose, constructed with FDA
compliant materials, is a pressure rated line that
connects the brass fill fitting in the fill box to the fill
circuit on the vessel. The vent line is as important as
any component in the system. It connects the safety
relief valves on the vessel to either the outdoor fill
box or to an alternative outdoor vent tube.
NOTE: Whether used as stationary or as portable,
the vessel must always be connected to an outdoor
vent line when it contains CO2 and is indoors.

Operation Facts and Procedures
Operation Facts
General Operating Procedures
1. A vessel’s normal internal operating pressure
(43) is between 140 psi and 165 psi.
1. Every day before starting operations and CO2
use check for:
• CO2 leaks (See “Safety”.)
• Pressure readings (43) & (46) x 2
• CO2 contents (22)
• Abnormal frost or condensation
• Anything unusual.
2. Vessel pressure can be as high as 300 psi after
a delivery, but returns to its normal operating
pressure after a day or two of normal CO2 use.
3. The carbonator gas supply pressure (45) is
normally between 90 psi and 115 psi.
2. Always use caution when working with CO2.
Read and understand the “Safety” section of
this manual.
4. The syrup gas supply pressure (44) is
normally 65 psi.
5. Frost or condensation on the vessel is normal
during periods of CO2 use.
3. The Carbo system does not require adjustment
under normal operating conditions.
6. Frost or condensation on the vessel before
starting the daily use of CO2 is a sign of a CO2
leak. Have the leak fixed.
4. Check the vessel daily before using CO2.
See ‘operation fact’ number 10.
5. In an emergency the flow of CO2 from or
through the Carbo-Mizer can be stopped by
closing the following valves:
7. The Mizer 450 holds 453 lb of CO2 for a use
rate of approximately 70 to 100 lb per week.
The Mizer 750 holds 771 lb of CO2 for less
frequent fills or a use rate of over 100 lb per week.
8. The contents gauge (22) displays the
approximate amount of liquid CO2 in the vessel.
9. CO2 becomes dry ice below a pressure of 61
psi. the shutdown circuit will stop CO2 flow if
the vessel pressure (43) reaches 70 psi or less.
The push-button reset valve is used to restore
pressure in the system after the cause of the low
pressure has been corrected.
Valves 33b or 33c to stop the flow of gas to
the beverage or syrup system respectively;
33a and 33d to stop gas flow from the vessel.
•
Valve 30 to stop CO2 flow or leakage
through the fill hose and/or the brass fill
fitting in the outdoor fill box.
•
Valve 33a to stop CO2 flow through the
pressure-building circuit.
6. For CO2 equipment issues, call your CO2
supplier or service specialist. Before calling
for service or trouble shooting assistance,
please have the following information at hand:
10. An isolation (shut-off) valve is open when its handle
is parallel to the valve body and the line. The valve
is closed when its handle is perpendicular to
the valve body and the line.
11. See the trouble-shooting section for additional
information on potential vessel problems.
