PREFACE
INTERNATIONAL CARBONIC INC. has enjoyed over 53 years of
manufacturing excellence in the field of carbonation and in the beverage
related industry. We have had a long and proud history with quality as our
standard and innovation as our goal. Originally started just after World
War II in Canfield, Ohio as Carbonic Dispensers. We enjoyed patents on
the first Sodajet type carbonator. This method of carbonation
instantaneously carbonated the water to 100% saturation. We developed
the first patented dispensing valve to dispense bulk beverage with
carbonation equal to or in excess of bottled beverages. A valve with three
flavors and soda was another first. We were the first to incorporate the
total postmix package, i.e., carbonation, refrigeration, and the ability to
dispense from one self contained unit. We have pioneered many such
firsts and will continue to develop advanced systems for the future, such
as electronic interrogatable portion controls to electronic liquid level
controls.
We hope you enjoy this piece of equipment that has been produced to
give many years of trouble free service. We thank you for your purchase
and hope we may serve you in the future.

CHAPTER I
GENERAL DESCRIPTION
This chapter gives the description, theory of operation, and design data for the SPACE
CADET REMOTE, (SCR) and related components.
SYSTEM DESCRIPTION
The Space Cadet is a complete self-contained remote cooling/carbonation unit which
when combined with related components, will produce a variety of cooled carbonated and
non-carbonated beverages.
The Space Cadet consists of a condensing unit, a water reservoir, water-cooling coil, a
carbonator tank, (carbonated systems only), an agitator pump, and syrup cooling coil(s).
The Space Cadet is manufactured in two configurations, i.e., (SC-R), SPACE CADET
REMOTE and (RC-SC-R) RECIRCULATING SPACE CADET REMOTE.
For proper function the Space Cadet must have a water supply, and electrical supply and
drainage. Other items that will be required if used in B.I.B., (Bag in Box), or transfer tank,
(FIGAL), installations will be high pressure regulator, Low pressure regulator, connecting
lines, quick couplers, or disconnects and C02.
WARNING: Before shipping or relocating a Space Cadet into a freezing
ambient environment empty plain and carbonated water. Syrup systems
should be flushed, ice bank melted, and water drained from water bath.
A freezing ambient environment will cause existing water in unit to freeze
possibly resulting in damage to pump/motor assembly, syrup coils, water
coil, water bath, etc.

THEORY OF OPERATION
The SCR was designed to manufacture and dispense carbonated or non-carbonated
beverages much like your local bottling plant that cans or bottles your favorite carbonated
or non-carbonated drink.
Initially water is chilled and then carbonated to dispense a quality drink. To chill the water
the water is routed through a water coil that is submerged in an ice-cold water bath. The
temperature of the incoming water is at ambient temperature as it enters the water coil.
As the incoming water passes through the water coil the heat is removed from the water
in the water coil and chilled to a temperature acceptable for a quality drink. The water is
now routed into a carbonator tank where this cold water is mixed with CO2. This water is
now transformed into a carbonic acid, (soda water), and then routed to a remote station
and then valves where it will be mixed with syrup concentrates and dispensed.
The water bath holds approximately 9 gallons of water. A certain amount of this water
will be transformed into ice, approximately 35 pounds. This water reserve and ice bank
will act as a reservoir for refrigeration. This reserve is utilized during peak periods when
the BTU output of the compressor is not sufficient to meet the demand of the draw.
It should be recognized that without refrigeration your carbonation system would not
produce a drink that will hold carbonation. There is a direct relationship between
dispensed temperature and the volumes of C02 that can be held in liquid form.
The following will give a general overview of the flow of individual circuits and a clearer
understanding of our mini bottling plant.
Carbon dioxide gas (CO2) passes from a C02 cylinder through high-pressure regulator
(S-101). The high-pressure regulator regulates the CO2 feeding the SCR and should be
set at 65-75 PSI. The gas, after leaving the high-pressure regulator, is routed through
flexible tubing to a low-pressure regulator. The flow of CO2 is teed to go in two directions
at the low-pressure regulator. One path takes the gas, set at 65 to 75 PSI, to the
carbonator tank. This gas must be at a pressure greater than the incoming water by at
least 25-PSI to assure the proper function of the carbonator. The second path of C02 is
routed through low-pressure regulator to be regulated at pressures suitable for the syrup
concentrate being dispensed. The low-pressure regulator may be set at many different
settings but primarily the settings are directed towards B.I.B. or transfer tank type
installations. The average settings may vary from 10 to 60 PSI, this of course will be
influenced by length of run, ambient temperature and baume of product. Typically B.I.B.
installations are set at an average of 40 PSI and transfer tank installations are set at an
average of 30 PSI.
As discussed earlier plain water enters the SCR through the incoming water line. This
water proceeds through the water coil where it is chilled prior to entering the carbonator
tank or in the case of non-carbonated drinks chilled prior to going directly to a valve.
Prior to entering the carbonator tank an optional regulator (S-208A) may be installed.
This assembly is utilized to maintain water pressure feeding a non-carbonated valve
when used in conjunction with a carbonated valve.
The water source should be regulated, this is normally performed by the use of an in line
water regulator. If the water is not regulated and the water pressure is equal or greater
than the incoming CO2 the act of carbonation will be greatly inhibited or completely
eliminated.

At the proper settings, the gas pressure will stop the water from entering the carbonator
tank. To force the water into the tank a liquid level control and motor/pump will be used.
This combination will force the water into the tank mixing the water and CO2 together.
The carbonator utilizes a Soda Jet Recirculating Principle. Our Company pioneered this
principle in the early 1950's. This principle produces instantaneous carbonation at
extremely large capacities of 100 gallons per hour minimum.
The level of the water within the stainless steel mixing tank, (carbonator tank), will
determine the cycle on or cycle off of the water pump and motor. The liquid level control,
in conjunction with a probe housed in the carbonator tank, control the pump motor. The
motor will come on when the carbonated water within the mixing tank recedes to a
predetermined low level and stops the pump motor when the carbonated water reaches a
predetermined high level.
During the cycle of operation, fresh water enters the carbonator tank through the soda jet
after passing through a short tube to the water pump inlet fittings. The water pump has
impellers which drives the water through a dual check valve and then through the soda
jet and into the carbonator tank.
The position and angle of the soda jet is fixed to direct an extremely high velocity solid jet
of fresh water so as to impinge upon the surface of the stored body of carbonator water
within the stainless steel mixing tank. The force created by this jet of fresh water entering
the mixing tank causes all the water within to cascade and foamesce through the carbon
dioxide gas area in a continuous recirculating-manner.
This action causes a breakdown of the surface tension of the water, forming numerous
minute gases filled water bubbles. The micro thin walls of these water bubbles
surrounded by gas both inside and out, offer maximum water surface for the absorption
of the gas. The size opening through this jet permits large volumes of water to be
carbonated.
As the incoming water is being carbonated, the level within the tank rises to contact the
upper probe, which will de-energize a relay on the liquid level control and stop the motor
from turning the pump. This motor will be inactive until water within the tank recedes
below the long probe, at which time, the relay on the liquid level control will close,
engaging the motor once again.
REMOTE CIRCULATING COOLING SYSTEM
The remote station circulating cooling system is used as its name implies to cool the
water, soda water, and syrup lines between the dispenser and the remote stations.
The cooling is accomplished by circulating the water from the cold water bath of the
dispenser through tubing to the remote station and then returning this partially warmed
water to the water bath.
When installing stations remote from the dispenser cabinet, the following operations are
very important:
Location of the Cabinet: - Locating the dispenser cabinet properly depends upon two
factors: convenience to the user and convenience of installation and service.
15

If cabinet is not used as a serving station it is permissible to place it in a basement, back
room, or any other out of the way place. However, it is important to locate the cabinet as
close as possible to the remote station in order to keep the heat loss through the
insulated extended lines at a minimum. When used as a serving station, it is necessary
to place the cabinet where it will be most accessible to the operator.
Water shut off valves and power switches should be located as near the cabinet as
possible in order to facilitate service. Where an air-cooled condenser is used, there
should be enough space surrounding the cabinet to insure adequate air circulating
through the refrigeration condenser. Space should also be provided if possible, for doing
service work on the cabinet. Note: when units are located in isolated rooms outside
ventilation is necessary and air conditioning is recommended.
CAUTION: In order to have even distribution of cold water, the cold-water circulating
lines must always be run in series even on multiple station installations.
IMPORTANT: Be sure to leave all connections and fittings exposed until after the entire
system has been pressure tested.
In order to insure maximum heat transfer between the braided plastic
lines (through which the water, soda, and syrup are carried) and the
circulating tubing, it is necessary to tape these lines firmly together.
When the remote lines consist of three syrup lines and one soda line, tape the soda line
and one syrup line to the inside of the out-going water circulating tubing and tape the
remaining two syrup lines to the inside of the return water circulating tubing.
When there is a fresh water remote line used, then the fresh water line and the soda line
are taped to the inside of the out-going water circulating tubing and the three syrup lines
taped to the inside of the return water circulating tubing. The lines should be taped at
one-foot intervals.
The two groups of lines should then be drawn together and taped firmly so that the
braided lines are on the inside of the cluster.
It is of utmost importance that the extended lines of the remote
installation be properly and adequately insulated. Failure to do this will
cause overloading of the refrigeration unit and ice bank, condensation
on the outside of the insulation and reduced cold drink dispensing
capacity.
CAUTION: All open ends, joints and connections of the insulation must be sealed air
tight to prevent outside air from entering the insulated duct. Outside air, which contains
moisture, would condense this moisture within the insulation duct resulting in the
insulation becoming wet, which would reduce its insulating qualities. Water dripping from
duct would also result.
Pressure Drop within the Carbonated Water Lines – All Soda systems will maintain the
pressure necessary to prevent any carbonation loss through out the entire system even
while the valve is open.
Attention must be given to avoid restrictions in the lines, which may cause a reduction in
pressure upon the carbonated water and allow some of the gas to escape from the
carbonated water in the lines.
