FREEZER APPLICATION AND SPECIFICATIONS
Remote Freezers
The freezer consists of a freezing cylinder with a rotating internal auger (dasher) that is belt-driven by an electric
motor. The auger scrapes frozen product off of the inside of the refrigerated cylinder.
Crathco remote beverage freezers are designed to operate in conjunction with a remote condensing unit or be
connected to a central refrigeration system. It is recommended that the condensing unit have no more than 2 1/2 hp
®
®
per barrel to ensure maximum efficiency. The refrigerant must be R404A (Dupont HP62 ). The refrigeration for each
barrel is controlled by the liquid feed solenoid. The liquid feed solenoid is opened and closed by the limit switch
attached to the drive motor. (When the product consistency reaches the desired point, the switch closes and
de-energizes the liquid feed solenoid 20 seconds later.) Twin units operate with each barrel independently. Quick
connect refrigeration connections are supplied with each unit. Each freezer is factory supplied with 5/8" suction and
3/8" liquid connections. The piping connecting the freezer with the remote condensing unit or central system should
be sized according to industry standards. The installer is responsible for sizing the refrigeration lines to the unit.
When properly operated and cared for, the remote freezers will provide many years of service. Proper care includes
regular cleaning and maintenance. To minimize the amount of maintenance necessary, follow the operating proce-
dures outlined in this manual.
There are four variations of the remote unit:
3341 – standard single barrel remote unit
3342 – standard twin barrel remote unit
3341A – single barrel remote unit with internal autofill system
3352 – dual barrel remote unit with internal autofill system

Remote Freezers (cont.)
The autofill system on the 3341A and 3352 models is designed to keep the product hopper full to a predetermined
level. This assembly eliminates the necessity of pre-mixing concentrate and water and the possibility of manual
mixing errors. The mixed product is automatically fed to a Remote Fill Control which is located in the freezer. The
Remote Fill Control then adds pre-mixed product to the freezer mix storage reservoir as required.
When the autofill switch is ON and when the level drops below the probe for 15 seconds, the product feed solenoid
opens. This allows the product from the remote pumping system to fill the hopper. When the liquid level reaches the
probe, the product feed solenoid closes. NOTE: As a safety, the refrigeration liquid feed valve closes until the level in
the freezer reaches the probe. To bypass the automatic feed feature, simply turn the autofill switch to manual. This
allows the refrigeration to operate independently of the autofill and the hopper must be filled manually.
Product Tips
These freezers were designed to dispense a wide variety of frozen beverages including frozen fruit juice, frozen
lemonade, slush and frozen cocktails. These products can be served in consistencies ranging from thin to fairly thick.
Two types of dispensing valve plungers and product consistency springs are available depending on the thickness of
the product being served. These parts are interchangeable depending upon your needs. One plunger, part W0480438
has one horizontal outlet slot and is used to serve thin to medium products such as frozen lemonade and slush. The
other plunger, part W0480451 has two horizontal outlet slots and is used to serve thicker product such as neutral
base frozen cocktails. A red spring, part W0631239, is used on the drive motor to adjust product consistency to serve
thin to medium products. The yellow spring, part W0631238, is used for thicker product. The spring is located next to
the drive motor behind the right hand side panel.
Over an extended period of time, some products, such as frozen cocktails that contain alcohol, have a tendency to
separate, or stratify. Separation of product on the mix storage hopper can result in frozen product quality inconsistency.
Simply keeping the product, in the mix storage hopper, stirred on a regular basis will eliminate this problem.
Some cappuccino or latte mixes contain dairy products which can spoil if not refrigerated. If the freezer is to be
turned off at night these products must be removed from the freezer.
Contact your local health department regarding its regulations for proper mix handling and storage.
Carburetor Assembly
Your new freezer uses a metering device, known as a carburetor, to feed the proper ratio of mix and air into the
freezing cylinder (and to prevent frozen product from rinsing out of the freezing cylinder). The carburetor, or carb tube,
is a tube with a hole, or series of holes, bored through the side. It is located in the hopper and fits in the hole that
leads to the freezing cylinder. Air flows into the freezing
cylinder through the top of the tube and mix flows in
through a smaller hole in the side of the carb tube. The
size of the mix inlet hole can be balanced with the viscosity
(thickness) of the liquid mix and product draw rate, in such
a way that the proper amount of mix is fed into the freezer
cylinder to blend with air at just the right ratio. Mix viscosity
varies by mix type, mix temperature and mix age. Different
serving rates also demand different feed rates. For many
products, the proper mix to air ratio is generally accepted
Standard carb tube Low overrun
Thick product carb tube
(W0471136)
to be two parts mix to one part air. This proportion
yields a finished product that is both tasty and prof-
itable. At this ratio, one gallon of liquid mix will yield a
volume of one and one-half gallons of frozen product.
(W0471076)
carb tube
(W0472060)
Figure A
This additional volume is the overrun in the product. Crathco offers three versions of carb tubes (see Figure A).
Depending on the product being served and overrun requirements there is a standard tube for most slush or cocktail
products, a low overrun carb tube that allows all air trapped in the freezing cylinder to escape and a smoothie/shake
carb tube. This carb tube has an outer sleeve that can be rotated to line up with different hole sizes to provide various
levels of overrun. Most applications only require the standard carb tube.

Mix Considerations – General
Freezing characteristics are affected by the amount of sweeteners and solids in the mix, called BRIX. BRIX can be
measured with an instrument called a refractometer. A BRIX reading of between 11 and 14 will provide optimum freezer
operation. Mixes with the correct BRIX level will freeze down to a smooth, uniform consistency. Mixes with too high a
brix level will take longer to freezer down and will yield a soft, wet, frozen product. Mixes with too low a brix level will
have larger ice crystals and will have a tendency to dispense slowly or freeze up machine.
Alcohol content affects product freezing characteristics. High alcohol content may prevent the freezer from serving a
product at proper thickness.
NOTE: Always take BRIX measurements using mix that has been thoroughly blended, before it is frozen. Always allow
frozen mix to thaw thoroughly before taking a reading.
For maximum output capacity always pre-chill mix before adding it to the freezer. Pre-chilled mix gives the freezer a
head start on the freezing process and will speed both initial freeze down and recovery time. It is normal for output
capacity to decrease when warm mix is added, or when the freezer is operated in a warm area.

2. Fill the mix storage hopper following the instructions on page 10. Allow
barrel to fill with product to proper level, then insert carb tube from parts
bag in hole toward rear of hopper. See Figure G.
3. Turn power switch to “ON” position.
4. Allow product to freeze in barrel. Compressor will turn off when product reaches
pre-set consistency.
5. To dispense product pull down valve handle and release when done.
6. If product consistency is not as desired, adjust per the instructions on page 7.
7. Refill mix storage hopper when “mix out” light is ON.
Figure G
8. Clean the unit regularly following local health codes.
9. Perform maintenance when necessary to increase the life of the unit. See chart in this manual for regular
maintenance schedule.
Mix Low Function
These models will sense when the mix is low in the hopper. On 3341 and 3342 models, a simple float mechanism is
used to sense when mix is low in the hopper. (see Figure G) When the mix level is low, the mix low light located on
the front of the machine will illuminate. NOTE: Do not run the unit under mix low conditions for long periods of time.
This can affect machine performance or damage componentry.
On 3341A and 3352 models, mix low is sensed via the autofill system. When the mix level is low, the mix low light
will illuminate continuously for 2 minutes. After 2 minutes the light will begin to blink off and on for the next 8 minutes.
At the end of the 10-minute time the light will illuminate fully again. After the 10-minute cycle, the mix out safety
function is activated making the unit inoperable. The safety function shuts off the autofill and refrigeration. The unit
can be reset back to the freeze mode by simply adding mix into the hopper.
NOTE: If the mix low safety function has activated disabling the unit, and the product has not been added for an
extended period of time – verify the product is okay for re-use. If it is not, use fresh product to restart the unit. Empty
the unit of old product and follow cleaning and sanitizing procedures (page 8).
Consistency Adjustment
From time to time, it may become necessary to readjust the consistency setting (thickness) to compensate for
variation between different mixes or to switch from one type of product to another. This adjustment is made
as follows:
1. Disconnect electrical power.
WARNING: Do not attempt to readjust the freezer until electrical power has been disconnected.
ƽ
Adjustment Screw
2. Remove right side panel (facing the freezer).
3. Use the adjustment screw, situated on the front of the drive motor mounting bracket to
change product thickness. Turn the thumbscrew (3 full turns for red spring, 1 turn for
yellow spring) to make a noticeable change in consistency. (see Figure H)
NOTE: Clockwise is for thicker product consistency and counter clockwise is for thinner
product consistency. (see Figure I)
4. Reinstall the side panel, reconnect power.
5. Turn freezer to “ON” and allow it to freeze to desired consistency.
Figure H
6. Check product. Repeat process until desired consistency is achieved.
Increase Thickness (turn clockwise)
NOTE: When making changes to a colder (thicker) setting, recheck
consistency again after the compressor has cycled off. When adjusting
(counter-clockwise) to a thinner consistency, a large portion of product
should be drawn from the dispense valve to reduce the product thickness
below the new set point (adjustment). Then allow the freezer to refreeze
product to the new setting.
Decrease Thickness (turn counterclockwise)

CARE AND CLEANING
Cleaning and sanitizing frequency must be followed according to state and local health department regulations.
NOTE: Each time the freezer is disassembled, all internal components must be thoroughly washed and sanitized
using procedures recommended by your local health department. In lieu of local department recommendations,
use a three compartment sink; one compartment to wash parts in detergent, one compartment to rinse, and one
to sanitize.
For units with internal autofill, see section on page 11 for instructions on cleaning and sanitizing the autofill system.
Drain and Rinse
1. If the freezer is empty, proceed to Disassembly and Cleaning. If there is product in the freezer, turn the front
panel switch to “CLEAN”. On models using Remote Fill Control, (3341A and 3352 models), turn internal autofill
“OFF” before draining.
2. Open the front dispensing valve and drain all product from the freezer. Close dispensing valve.
3. Remove the carb tube and pour water into the storage hopper. Allow the water to fill the freezing cylinder.
NOTE: Use approximately 2 1/2 gallons (10 liters) of cool water per barrel to rinse freezer.
4. Turn the freezer panel switch to “CLEAN” for 5 minutes.
5. Open the dispensing valve and drain the water from the freezer. Close valve.
6. Turn the freezer “OFF”.
Disassembly and Cleaning
NOTE: For cleaning and sanitizing before initial start-up, remove carb tube, dispense plunger, handle and spring
from parts bag first.

Clean-In-Place Procedure (Daily Cleaning)
This equipment has been approved for a Clean-In-Place procedure that does not require complete disassembly on
a daily basis. The unit still requires regular complete disassembly for cleaning and sanitizing. To perform the C-I-P
procedure follow the instructions below:
1. Empty any product in the machine and turn to OFF.
2. Disassemble the dispensing valve assembly following the instructions in Disassembly and Cleaning.
NOTE: Leave the valve block in place. Only disassemble the plunger, handle, spring, o-rings and pin.
3. Remove carburetor assembly from hopper and remove o-rings.
4. Take all components to the cleaning area.
5. Carefully inspect the o-rings for cracks, chips or cuts and replace if necessary.

Cleaning/Sanitizing Internal Autofill (Model 3341A and 3352 Only)
Remote Pump Sanitizing
The BRIX pump does not require any maintenance. However, depending on the concentrate type and it’s manufac-
turers requirements, the pump and ALL equipment in the system will need periodic sanitizing. The frequency of
this procedure is dependent on the water condition, temperature and product type. Some concentrates may
contain exceptionally “stringy” pulp that may become lodged within the BIB and/or dispenser valve inhibiting perform-
ance. If concentrates of this kind are used, the system may need more frequent sanitizing to flush out build-up.
WIth a “Teed” or pre-mixed system it is recommended that the intervals between sanitizing be more frequent than
post-mix systems. The reason for this is that when a concentrate is mixed with water, it may increase the possibility
of product spoilage.
NOTE: The following procedure must be followed to assure compliance of NSF listed sanitizing requirements for
the SHURflo BRIX pump (only). It is recommended that the sanitizing instructions provided with the BRIX
pump installed be followed. This procedure will not flush and sanitize the concentrate outlet line between the
3-way valve and dispenser. To properly sanitize the concentrate line, repeat the procedure in the “Dispense” mode
and perform a product purge of the system.
Materials Required
1. Non-sudsing liquid detergent (such as common household automatic dishwasher liquid detergent)
2. Household bleach (Sodium Hypochlorite solution; 5.25%) or equivalent.
3. Clean 5 gal. (19 L) bucket
4. Measuring cup
5. An adapter is needed to hold the QCD (BIB) fitting on the concentrate suction line open. A connector cut from an
empty bag will work.

Sanitizing Procedure
1. Fill the bucket with 4 gal. (15.14 L) of warm water 120ºF – 180ºF (48ºC – 82ºC).
2. Measure 4 oz. (1/4 cup) (118cc) of the liquid detergent and add to the water.
3. Measure 2 oz. (1/8 cup) (60cc) of bleach and add to the water, then stir, mixing evenly.
NOTE: 1/2 oz. (15cc) of bleach per gallon (3.8 L) of water yields a solution of approximately 200 ppm Sodium
Hypochlorite needed to satisfy NSF sanitizing requirements.
4. Disconnect the concentrate line from the BIB and install the adapter on the quick disconnect so the line is open
to the sanitizing solution. Place concentrate inlet line into the bucket so that the Q.C.D. will stay at the bottom.
5. Position the SHURflo sanitizing valve in the “SANITIZE” mode. Open the dispenser valve allowing ALL the
solution to be pulled through the Q.C.D. fitting into the BRIX pump and out the water outlet line through to the
dispenser.
6. When the bucket is empty (approx. 15 min.), return the valve to the “DISPENSE” mode.
7. Product Purge: Reconnect Q.C.D. of the inlet line to the concentrate supply. Open the dispenser allowing the
pump to operate until all sanitizing solution is purged from the system, assuring that no off-taste will be detected.
Allowing the pump to operate until all sanitizing solutions is purged from the system, assuring that no off taste
will be detected.

ƽ until electrical power has been disconnected.
Suggested Daily Maintenance
1. Clean, lubricate and sanitize the freezer following guidelines.
2. Clean the exterior of the freezer using a soft wet cloth. (Wipe down spinner if attached)
3. Empty drip tray.

How to Adjust Belt
CAUTION: Unplug the machine before performing any adjustments. This procedure must be done by a
ƽ
qualified technician.
Check the belt tension. The proper belt deflection is 1/2" over all. If the deflection
is more than 1/2" the motor will need to be lowered. If the deflection is less than
1/2", the motor will need to be raised. Follow this procedure to adjust the motor to
achieve proper belt tension. (see Figure BB)
1. Unplug the machine and remove both side and rear panels.
2. Locate the motor flange bearings. These are the side mounted bearings that
hold the motor to the cradle. The motor is double shafted and the shaft
extends through a bearing on each end. The bearing is held to the motor
cradle by two allen bolts on each bearing.
Figure BB
3. Loosen the allen bolts on each bearing. Do not loosen the setscrews that hold
the bearing collar to the motor shaft.
4. Lower the motor or raise the motor as needed. The motor must be kept level from front to back. Do not lower or
raise only one end of the motor. This will result in excessive belt wear and belt noise.
5. Tighten all four allen bolts down. Align the motor pulley with the top pulley if needed.
6. The motor pulley should be in alignment with the large (driven) top pulley. Use a straight edge along the
top pulley.
7. If the pulleys are not in alignment, loosen the setscrew on the motor pulley and move either in or out as needed.
8. Tighten the setscrew back down on the motor shaft (use of non-permanent loc-tite is recommended). Please be
sure the setscrew is tightened down on the flat surface of the motor shaft.
9. Return the unit back to service.
How to Change Back Lit Sign Merchandiser Bulb
1. Remove the two screws, located on the top of either side of the sign.
2. Lower the metal enclosure that frames the merchandiser insert.
3. Pull merchandiser enclosure down and out.
4. Replace bulb inside.
5. Reassemble. For ease of assembly, put merchandiser in light box before placing metal enclosure back on.

Preventative Maintenance Procedure (Every 6 to 12 Months)
A preventative maintenance visit should be performed every 6 to 12 months depending on the usage and environ-
ment where the unit is placed. (Ex. seasonal machines – once before season, year round machines – twice per
year). The following procedures should be performed during a preventative maintenance visit. This does not take the
place of daily care and cleaning procedures as described by local health codes and the manual. PM kit #W0890157
contains the standard replacement parts needed for preventative maintenance including o-rings, standard seal kit
stator bearings and drive belt. Units with a coconut oil product seal should order all parts separately. Units with
scraper blade dasher will require the scraper blades be ordered separately.
• Verify ventilation is adequate (Air-cooled units: 6" minimum on both sides, open at top, and as far as possible from
dust sources; Water-cooled units: 0" on both sides, 3 -6" at rear of unit and open at top).
• Verify adequate water flow and drain connections on water-cooled versions.
• Check product temperature and consistency for proper setting (refer to product manufacturer’s recommendation) –
adjust if necessary. Where equipped be sure to check the temperature in both the hopper and cylinder.
• Ensure product is being mixed properly and is within specification (check brix – most products should be around
13% – refer to product manufacturer’s recommendations for exact recommended brix).
• Check for any leaks.
• Empty product from the unit. Disassemble unit completely (as if for cleaning).
• Clean and sanitize all disassembled parts following the cleaning instructions in the manual.
• Clean and sanitize hopper, freezing cylinder and splash zones on the machine.
• Check condition of all panels and lids – replace if necessary.
• Check dasher scraper blades for wear if equipped – replace once per year minimum.
• Check dasher for signs of wear – replace if necessary. Verify alignment when replacing.
• Check valve body gasket for wear – replace once per year minimum.
• Check valve body knobs (used to hold valve body in place) – replace if necessary.
• Check condition of shaft seals and stator bearings – replace once per year minimum.
• Inspect drip cup at back end of freezing cylinder for signs of seal leakage.
• Replace o-rings on hopper float (where necessary), dispense valves and carb tubes (lubricate).
• Lubricate parts where appropriate (dispense valve o-rings, carb tube o-rings, rubber boot of stationary shaft seal).
• Re-assemble unit and sanitize hopper and freezing cylinder by running CLEAN cycle.
• Clean and sanitize spinner if equipped.
• Check operation of merchandiser and mode lights – replace light bulbs if necessary.
• Clean reusable filter if equipped. Check condition of filter and replace if necessary.
• Clean condenser.
• Inspect the drive shaft and motor shaft bearings for excessive wear (drive shaft hole rounding out) – replace if
necessary. Verify alignment when replacing.
• Check V-belt tension (should be 1/2" – 5/8") and verify all set screws are tightened – adjust if out of range. Replace
belt once per year minimum.
• Verify compressor operation and freezer controller operation.
• Check electrical connections (outlet should be properly grounded with amperage capacity equal to or over the
amperage specified on the serial tag).
• Check fan operation (condenser fan) and clean fan blades if necessary.
• Review proper periodic care and cleaning instructions (disassembly, cleaning, sanitizing, lubrication, and re-assembly)
with store personnel. Train store personnel to follow proper procedures (stress importance of store level mainte-
nance ie. lubrication, filter cleaning, etc.).
• Make sure store personnel have appropriate supplies (lubricant, cleaning brushes and sanitizer) to care for machine.
