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 been located in the Southern
California area since 1952 and have 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 post-mix package, i.e.,
carbonation, refrigeration & the ability to
dispense from one self contained unit. We have
pioneered many such firsts and will continue to
develop advance systems for the future, such as
electronic interrogatable portion controls to
electronic liquid level controls.
We hope you enjoy this product which 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.

LF-MS-J-PP CHAPTER I
GENERAL DESCRIPTION
This chapter gives the description, theory of operation, and design data for the LIL
FELLA MID SIZE PERISTALTIC PUMP unit, (LF-MS-J-PP), and related components.
SYSTEM DESCRIPTION
The LF-MS-J-PP is a complete self-contained Juice unit which when combined with
B.I.B containers, will produce a variety of cooled non-carbonated beverages. The LF-
MS-J-PP consists of a water bath, refrigeration system, valves, and modular
peristaltic pump compartment. The cabinet is housed in an attractive black vinyl
and the peristaltic pump module is housed in a rugged stainless steel housing. The
LF-MS-J-PP has been designed to eliminate the use of bag in the box pumps and
associated components. The LF-MS-J-PP will dispense product with B.I.B.’s at a
distance of 100 feet horizontally or 17 feet vertically. THESE DISTANCES ARE ONLY
POSSIBLE IF THE SUPPLY LINE HAS COMPLETE INTEGRITY. IF EVEN THE
SMALLEST VACUUM LEAK IS ALLOWED THESE DISTANCES ARE NOT POSSIBLE.
The LF-MS-J-PP can brix from one to one up to twenty to one by using a state of the
art controller/potentiometer adjustment.
For proper function the LF-MS-J-PP must have a water supply, and electrical supply
and drainage. The LF-MS-J-PP is designed with a unique lift off drain pan that can be
emptied at any convenient drain outlet.
WARNING: Before shipping or relocating a LF-MS-J-PP into a
freezing ambient environment evacuate all plain 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
water coil, peristaltic pumps, water bath, valve(s), etc.
Water Filter Recommended (Optional) See Manufacturer Specifications for Operating
Conditions

THEORY OF OPERATION
The LF-MS-J-PP was designed to manufacture and dispense non-carbonated
beverages much like your local bottling plant that cans or bottles your favorite
non-carbonated drink.
The water bath must be filled with approximately 5 gallons of water. After all
connections are made and activation of the refrigeration a certain amount of
this water will be transformed into ice, approximately 17 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.
3

The incoming water is routed through a water coil that is submerged in the
above mentioned water bath. The temperature of the incoming water is at
ambient temperature as it enters the submerged 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,
normally a temperature of 33 to 34 degrees is reached. The water is now
directed to a valve where the water and syrup are mixed in proper proportions
to dispense a quality drink. Depending on the ratio of water versus syrup the
temperature will rise and be dispensed at approximately 40 degrees
Fahrenheit.
With the incorporation of the peristaltic pump the necessity for an air or CO2
supply is no longer necessary, this includes the low and high-pressure
regulators normally needed for a standard juice unit. The peristaltic pumps
will pull the syrup concentrate from the B.I.B., (bag in the box), and then push
the syrup through syrup cooling coils, (optional), and then to the valve where
the syrup concentrate and water are mixed in a proper ratio to dispense a
quality drink. The syrup enters the LF-MS-J-PP through a unique 1/4” X 3/8 S-
162 bulkhead fitting at the rear of the unit.
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 can vary. This variance of water pressure can effect our dispensed
product.

3. Be sure all connections are water-tight.
INSTALL B.I.B.
1. Place B.I.B. (Bag in the Box), as close as possible to LF-MS-J-PP unit, preferably
no farther than 15 feet. The LF-MS-J-PP will dispense product with the B.I.B.’s
at a distance of 100 feet horizontally or 17 feet vertically. THESE DISTANCES
ARE ONLY POSSIBLE IF THE SUPPLY LINE HAS COMPLETE INTEGRITY. IF
EVEN THE SMALLEST VACUUM LEAK IS ALLOWED THESE DISTANCES ARE NOT
POSSIBLE.
2. Lay out syrup lines from unit to B.I.B.
3. Connect lines from B.I.B. to inlet on LF-MS-J-PP.
4. Activate Q.C.D.
5. Check all connections for leaks, (see Chapter IV).
12

CONNECTING WATER INLET
WATER PIPE CONNECTIONS AND FIXTURES DIRECTLY CONNECTED TO
POTABLE WATER SUPPLY SHALL BE SIZED, INSTALLED AND MAINTAINED
ACCORDING TO FEDERAL, STATE, AND LOCAL LAWS.
The water connection on the LF-MS-J-PP is made to a flexible water line by
means of a 3/8”, male hose or barb connection.
After all primary water lines are made up, but prior to connecting water supply
to cabinet, be sure to thoroughly flush all incoming water lines to remove all
scale and any impurities that may be in the lines. It is imperative that the
fresh water-conduit have not less than 3/8” I.D. passageway for any distance
greater than ten feet from the LF-MS-J-PP. It can be reduced to 3/8” O.D.
copper tubing and connected to the water inlet connection with-in ten feet of
the LF-MS-J-PP. All water inlet connections are clearly tagged.
ELECTRICAL REQUIREMENTS:
The LF-MS-J-PP requires a 120 VAC, single phase, 60 Hertz power circuit, and
must be wired in accordance with N.E.C. or local ordinance.
NOTE: Check CHAPTER I for running amperage and connect to
appropriate electrical circuit.
13

CHAPTER III
LF-MS-J-PP
PREPARATION
All steps in previous chapters should be understood and carried out before
proceeding.
PREPARING SYSTEM FOR OPERATION
Be sure that electrical power is unplugged, valve on water supply line is closed.
PREPARING AND STARTING REFRIGERATION UNIT
1. LF-MS-J-PP refrigeration is pre-set at factory and ready to operate.
2. Remove lid.
3. Fill water bath with clean water until water runs out of condensate drain
outlet, (S-657), (approximately ½” from top of water bath). DO NOT USE
DISTILLED WATER.
4. Open water inlet supply line.
5. Plug LF-MS-J-PP power cord into electrical receptacle box, turn power
switch to the "ON" position. Make sure compressor, condenser fan motor,
agitator motor start. The process of cooling the water bath will commence
after filling water bath. With ambient and water temperature of 75 degree “F”
initial pull down or formation of complete ice bank will take approximately 3.5
hrs. When full ice bank has been formed, compressor and condenser fan
motor will stop. Agitator will continue to operate, circulating water in water
bath.
PURGE DISPENSING VALVES
Dispense water from dispensing valves until all air is purged from water lines.
ADJUST WATER FLOW RATE
Adjust dispensing valves water flow rate to approximately 6 oz. in 5 seconds.
ADJUST WATER-TO-SYRUP "RATIO"
Adjust dispensing valves for Water-to-syrup "Ratio". Contact supplier of syrup
concentrate for recommended ratio.
14

CHAPTER IV
LF-MS-J-PP
OPERATORS INSTRUCTIONS
This chapter covers operators’ responsibilities for daily pre-operation check,
adjustments, replenishing C02 and cleaning, and sanitizing.
DAILY PRE-OPERATION CHECK
1. Make sure B.I.B.’s full and ready to dispense.
2. Make sure nozzles are clean and in place.
3. Make sure electrical power is supplied to unit.
COOLING UNIT MAINTENANCE
NOTE: Air circulation through the condenser coil required to cool the condenser
coil/compressor, is drawn in through grills on cooling unit, through
condenser coil and is exhausted out grills on either side and rear of the
unit. Restricting air circulation through the cooling unit will decrease its
cooling capacity.
To avoid needless and sometimes costly repairs, it is imperative to keep condenser
fins clean. This may be accomplished by one of three methods. One method is use
of a condenser brush (a longhaired, soft bristle brush) to gently sweep fins of
condenser clean. Second method is to use a strong vacuum. The third method is to
use C02 or an air hose to blow out condenser. The latter method should only be
attempted after normal business hours to avoid dust contamination.
CHECKING WATER BATH
Periodically check water level in water bath. If water level is low, water should be
added as instructed for maximum product cooling. This dehydration will normally
not occur in normal temperate climate zones. With normal humidity the opposite will
occur therefore it is paramount that the condensate drain be installed.
CHANGING WATER BATH
Drain water bath a minimum of twice a year. This can be accomplished by locating
the standpipe in the water bath area and removing by twisting and pulling up. Once
water is drained, water bath, water coils, bath walls, etc. should be cleaned. Special
care should be taken to clean the ice bank control bulb. Replace standpipe and
refill with water. Fill water bath to top of standpipe, (S-657).
CLEAN NOZZLES
Remove nozzles nightly and let soak in warm water. DO NOT SOAK IN HOT HOT
WATER OR BLEACH WATER!
15

CHAPTER V
SERVICE AND MAINTENANCE
This chapter describes service and maintenance procedures to be performed on LIL
FELLA MID SIZE PERISTALTIC PUMP JUICE unit systems and related components.
PERIODIC INSPECTION AND CLEANING
Daily:
1. Clean any storage tanks/B.I.B. racks, connecting sockets/Q.C.D.’s and general
storage area with warm water.
2. Clean the beverage dispensing area.
3. Remove and clean nozzles and all exposed areas on valves.
4. Wipe exterior of unit with moist towel.
Weekly:
1. Order syrup to maintain product inventory.
2. Check condenser coil for obstructions or dirt.
Monthly:
1. Clean condenser fins or filter to make sure the refrigeration unit has adequate
air flow.
2. Inspect components of cooling unit water bath for cleanliness.
3. Check entire system for leaks or damaged components. Repair as necessary.
PERIODIC CLEANING
Periodically wash all external surfaces of cooling unit, rinse with clean water, then
wipe dry with a clean soft cloth.
DO NOT USE ABRASIVE TYPE CLEANERS.
CLEANING CONDENSER COIL
IMPORTANT: Air circulation through the condenser coil required to cool the
condenser coil/compressor, is drawn in through grills on cooling unit,
through condenser coil and exhausted out grills on the other side of
unit. Restricting air circulation through the cooling unit will
decrease its cooling capacity.
16

NOTE: Cleaning condenser coil should be done during non-business hours.
1. Unplug refrigeration unit power cord from electrical socket.
2. Remove 6 screws securing service panels, 2 screws per service panel. Remove
panels in preparation for service.
3. Vacuum or use a soft brush to clean fins of condenser coil. Use low-pressure
compressed air or C02 gas to blow through condenser fins. This should only be
performed after normal business hours to prevent dust contamination. A damp
cloth on back-side of condenser coil will prevent some dust contamination.
4. Plug refrigeration unit power cord in electrical socket.
CHANGING WATER BATH
NOTE: The water bath should be changed and all components in water bath should
be cleaned as often as necessary to keep it clean. A convenient time to perform this
operation is when the system is being sanitized.
1. Unplug refrigeration unit power cord from electrical socket.
2. Remove lid from water bath.
3. Look down into water bath (if necessary, use flashlight) and inspect water bath,
evaporator and all components for cleanliness. Water coil, refrigeration evaporator
and all components should be clear and free of foreign particles.
4. Pull out standpipe and allow water to drain.
S. Use fiber brush and carefully clean mineral deposit from all components.
6. Wash evaporator coil with a mild soap. Copper cleans well with mild solution of
citric acid (1 cup of citric acid for 2 gallons of water). Stainless steel cleans well
with carbonated water. Then rinse with clean water.
7. Rinse out water bath with clean water until water running out of drain hose is
clean.
8. Install stand-pipe in drain outlet.
9. Fill water bath to top of stand pipe, (condensate drain), with water.
10. Install lid.
11. Plug LF-MS-J-PP unit power cord in electrical socket.
