General Information
Freezer Application and Specifications
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. 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.) Quick connect refrigeration connections are
supplied with each unit. Each freezer is factory supplied
with 1/2" 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 procedures outlined in this manual.
Product Tips
The Model 3341 was 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 latté 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 running 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 to be two parts mix to
one part air. This proportion yields a finished product
that is both tasty and profitable. At this ratio, one
gallon of liquid mix will yield a volume of one and one-

General Information (continued)
half gallons of frozen product. This additional volume
is the overrun in the product. Crathco offers two
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
and a low overrun carb tube that allows all air trapped
in the freezing cylinder to escape. 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. The amount of
sweeteners and solids is 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 this BRIX level
will freeze down to a smooth, uniform consistency.
Mixes with too high a BRIX level will take longer to
freeze 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.
Alcohol content also affects product freezing
characteristics. High alcohol content may prevent the
freezer from serving product at proper thickness.
Note: Always take BRIX measurement 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.
Shipment Transit
1. The freezer has been operated and tested
at the factory. Upon arrival the complete
freezer must be thoroughly checked for any
damage which may have occurred in transit.
NOTICE: A Tip (N) Tell warning device is placed on
each shipping carton at the factory. If the indicator is
red, the carton has been tipped in transit. (See Figure
B.)
2. THE CARRIER IS RESPONSIBLE FOR ALL
DAMAGE IN TRANSIT WHETHER VISIBLE
OR CONCEALED. DO NOT PAY THE
FREIGHT BILL until the freezer has been
checked for damage. Have the carrier note
any visible damage on the freight bill. If
concealed damage or shortages are found
later, advise the carrier within 10 days and
request inspection. The customer must place
any claim for damage and/or shortage with
the carrier. Grindmaster-Cecilware cannot
make any claims against the carrier.
Installing Your Unit
CAUTION: Beverage freezers are heavy pieces of
equipment. It is recommended that moving or lifting
the unit be done by two people to avoid injury.
1. Place the self-sealing rubber pad (shipped
with the freezer) on a level counter that is
stable and strong enough to safely support
the freezer’s weight (200 lbs. / 90.7 kg), or
if equipped with legs instead of pad, install
legs by screwing them into the four leg
holes on the bottom of the unit. (Leg Kit
Part # W0890220 (4) 4” (10 cm) Legs)
2. Make sure freezer is to be placed in a
location that is within 6’ (1.8m) of a
properly grounded circuit and allows
adequate space at each side and above for
proper air circulation.
NOTICE: Failure to allow adequate ventilation will
void the warranty and reduce freezer performance.
NOTICE: Locating the unit in high ambient
temperatures (over 100°F / 37.8°C) will significantly
reduce the performance of your machine.
3. Remove the side panels. Supporting all four
sides, lift machine up (by the frame) and
place in appropriate area on top of rubber
pad.
NOTICE: If equipped with spinner, do not lift unit up
by spinner shaft. It will cause serious damage to spinner.

How to Operate
1. Sanitize unit following the cleaning
instructions starting on page 8.
2. Fill the mix storage hopper following the
instructions on page 12. 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 this page.
7. Refill mix storage hopper when “mix out”
light is on.
8. Clean the unit regularly following local
health codes.
9. Perform maintenance when necessary to
increase the life of the unit. See the chart in
this manual for regular maintenance
schedule (page 13).
Mix Low Function
This model utilizes a simple float mechanism to sense
when mix is low in hopper. (See Figure G.) When the
mix level in the hopper is low, the mix low light located
in the front of the machine next to the valve block will
illuminate.
NOTICE: Do not run the unit under mix low
conditions for long periods of time. This can affect
machine performance or damage componentry.
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.
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.)
NOTICE: Turn screw clockwise for thicker product
consistency and counter clockwise 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.
6. Check product. Repeat process until desired
consistency is achieved.
NOTICE: 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 must 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.

Disassembly and Cleaning (continued)
NOTICE: The best way to remove an O-ring is to first
wipe off all of the lubricant using a clean paper towel.
Pinch the O-ring upward with a dry paper towel
between your index finger and thumb. When a loop is
formed in the O-ring, roll it out of the groove with your
other thumb. Always remove the O-ring farthest from
the end of the plunger first. Carefully inspect the O-
rings and replace if necessary. Be careful not to pull or
tug excessively on O-rings. O-rings can be distorted which
will deteriorate sealing performance.(See Figure N.)
3. Remove the dasher assembly from inside the
freezing cylinder, taking care to avoid
damaging the rear seal assembly at the back of
the freezing cylinder. Disassemble the dasher
assembly by removing the stator rod and front
and rear stator rod bearings.
4. Remove stationary half of the shaft seal
assembly from the back end of the freezer
cylinder. This is accomplished by reaching into
the cylinder and pulling seal out with your
index finger. (See Figure O.)
5. Slide the rotary half of the seal off the dasher
shaft. Inspect both seal components carefully
for nicks or cracks. Replace seal if defective.
NOTICE: To prevent leakage the surfaces of the rotary
seal and the stationary seal must be smooth with no
chips or cracks.
NOTICE: All units are shipped with a standard ceramic
seal (Part # W0340201) unless otherwise specified.
Certain products contain coconut oil, which requires a
different sealing material. For these products, use the
coconut oil seal (Part # W0340210). The stationary half
of the standard seal has a white polished surface. The
stationary half of the coconut oil seal has a glossy black
surface.
6. Remove carb tube from bottom of hopper and
remove O-rings. (See Figure P.)
7. Remove drip tray and empty contents.
8. Take all components to the cleaning area.
9. Prepare 1 gallon (3.8 liters) solution of hot tap
water and common dishwashing detergent.
10. Using a warm, mild detergent solution,
thoroughly wash all components, including the
inside of the freezing cylinder and the mix
storage hopper. DO NOT WASH COMPONENTS
IN A DISHWASHER.
11. Use a medium sized brush to clean the bottom
of the valve body and the inside of the plunger
bore with detergent solution, taking care to
remove only remaining lubricant. (See Figure

2. Wet the inner rubber lip of the rotary half of
the seal and the back end of the dasher shaft
with water. Slide rotary half of assembly onto
the dasher shaft, RUBBER FIRST, with the
smooth sealing surface facing the back of the
dasher. (See Figure R.) Be sure the rotary half is
fully seated against the shoulder of the shaft.
3. Insert the stationary half of the seal into the
ribbed rubber boot with the polished surface
facing out (forward).
4. Lightly lubricate the ribbed rubber boot of the
stationary ceramic seal (taking care not to get
any lubricant on the polished surface) and insert
it straight back into the recess at the back of the
freezing cylinder, RUBBER FIRST. (See Figure S.)
NOTICE: The stationary half of the seal must be
completely dry before reassembling. If the circular half
of the seal is white, make sure that the grooved side is
toward the rubber. If the circular half is black, be sure
the glossy side is facing out.
5. Reassemble the dasher assembly, as shown in
Figure T. Insert the larger front and smaller rear
white plastic bearings into dasher, then slip in
the stator rod.
6. Carefully and slowly guide the dasher into
the freezing cylinder, taking care not to
damage the seal assembly. Turn dasher shaft
until it engages the square drive coupling. Slide
the dasher back into the cylinder so that the
two smooth sealing surfaces meet. (See Figure

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
environment 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. One kit is required for each
barrel receiving maintenance. 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” (15 cm) minimum on both sides, open at
top, and as far as possible from dust sources;
Water-cooled units: 0” on both sides, 3 - 6” (7.6
- 15 cm) 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 food 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 food 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). Lubricate with FDA
approved food grade lubricant.
• 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” or
1.3 - 1.6 cm) 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 condenser fan operation 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 maintenance i.e. lubrication, filter
cleaning, etc.).
• Make sure store personnel have appropriate
supplies (lubricant, cleaning brushes, and
sanitizer) to care for machine.

How to Adjust Belt
CAUTION: Unplug the machine before
performing any adjustments. This procedure
must be done by a qualified technician.
Check the belt tension. The proper belt deflection is
1/2” (1.3 cm) over all. If the deflection is more than 1/2”
(1.3 cm) the motor will need to be lowered. If the
deflection is less than 1/2” (1.3 cm), the motor will need
to be raised. Follow this procedure to adjust the motor
to achieve proper belt tension. (See Figure CC.)
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.
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. Align the motor pulley with the top pulley if
needed. Tighten all four allen bolts down.
NOTICE: The motor pulley should be in alignment
with the large (driven) top pulley. Use a straight edge
along the top pulley.
6. If the pulleys are not in alignment, loosen the
setscrew on the motor pulley and move either in or
out as needed.
7. Tighten the setscrew back down on the motor
shaft (use of non-permanent Loctite®is
recommended). Please be sure the setscrew is
tightened down on the flat surface of the motor
shaft.
8. Reassemble and return the unit back into 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.

Freezer problems originate from three sources - improper operation, mix problems, or mechanical malfunction.
Always check for improper operation and mix problems first, as they are the most common cause of most
equipment problems.
CAUTION: Always disconnect power before attempting any maintenance procedures.
Only a qualified service technician should perform electrical and mechanical adjustments or repairs.
