FREEZER APPLICATION AND SPECIFICATIONS
Model 331
1
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. A torque sensing mechanism
controls compressor operation to maintain desired product consistency. The freezer utilizes either an air-cooled or
water-cooled refrigeration system to freeze the product. Aself-closing dispensing valve is attached to the front of the
freezing cylinder. The unit has an adjustable consistency control and an out of product indicator.
When properly operated and cared for, the Model 3311 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 T
ips
The Model 3311 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.
Page 2 Model 3311
Product Tips (cont.)
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 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
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-half gallons of frozen product. 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. 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.

Accessory Inst
allation
The Model 3311 has several optional accessories that can be added
to the unit in the field to meet your application’s needs. These
accessories come with installation instructions.
• Spinner - Spinners are typically used in applications that add
flavoring to a frozen neutral base product after it is dispensed.
Allows operator to serve a wider variety of frozen drinks from one
machine (i.e. hazelnut added to cappuccino). See Figure E.
• Concealed Air Filter - Prevents dust from clogging the condenser.
Ideal for applications near beaches. Helps maintain maximum air
flow and optimum freezer performance. See Figure F.
NSF approved. Part # W0890200 stainless steel; W0890208 black.
• Exposed Air Filter - Similar to concealed air filter. Not NSF
approved. Part # W0890206. See Figure G.
• Valve Lock Security Bracket - Part # W0471135. Ideal for self-service locations to
prevent unauthorized use. Lock must be purchased separately. See Figure H.
• Remote Fill Control - Automatically refill the mix storage hopper. Provide
additional labor savings by pre-mixing product automatically and monitoring
system to maintain the mix hopper level.
• Private Label Header - Aprivate label or different drink header can be installed by
removing two screws from the electrical box cover. Place the header
(transparency) between the clear and opaque plates (plastic lens). Put these in
place under the lip of the machine top. Slip the electrical box cover back on to the
machine and reinsert the screws. (See Figure I) Grindmaster offers a variety of

margarita, pina colada, frozen cocktail, frozen daiquiri and smoothie.
OPERATION AND ADJUSTMENTS
How to Operate
1. Sanitize unit following the cleaning instructions starting on page 10.
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 J.
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.
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
1. This model utilizes a simple float mechanism to sense when mix is low in
hopper. (See Figure J) 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.
NOTE: Do not run the unit under mix low conditions for long periods of time. This
can affect machine performance or damage componentry.

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 K)
NOTE: Clockwise is for thicker product consistency and counter clockwise
is for thinner product consistency. (See Figure L)
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.
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.

CARE AND CLEANING
Cleaning and sanitizing frequency must be followed according to state and local health department regulations.
NOTE: Each time the freezer is fully disassembled, all foodzone freezer components must be thoroughly washed
and sanitized using procedures recommended by the local health department. In lieu of local health department
recommendations, use a three compartment sink; one compartment to wash parts in detergent, one compartment to
rinse, and one to sanitize.
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”. Most users schedule cleaning when product in the hopper is low to minimize product loss.
2. On freezers using the optional Remote Fill Control and Proportioning Pump, turn “OFF” the water valve on the
Proportioning Pump, using the valve next to the inlet pressure regulator and turn the switch on the Remote Fill
Control to “OFF”.
3. Open the front dispensing valve and drain all product from the freezer. Close the dispensing valve and turn
freezer to “OFF”.
NOTE: Use approximately 2½ gallons (10 liters) of cool water to rinse product out of freezer.
4. Remove the carburetor tube and pour water into the storage hopper. Allow the water to fill the freezing cylinder.
5. Turn the panel switch to “CLEAN” for 5 minutes.
6. Open the dispensing valve and drain the water from the freezer.
7. 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.
1. Disassemble the dispensing valve assembly (Figure M). Pull out valve handle retaining pin while supporting the
valve plunger from the bottom (Figure N). Push up on the valve plunger and remove the stainless handle
(Figure O). Slide the valve plunger and spring downward to remove (Figure P).
2. Remove knobs and carefully remove the front dispensing valve assembly, leaving the dasher assembly in the
cylinder. Remove the o-rings from the plunger assembly and back of the dispensing valve body. (See Figure Q)
NOTE: 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.
(See Figure Q)
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.

Disassembly and Cleaning (cont.)
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 R)
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.
NOTE: To prevent leakage the surfaces of the rotary seal and the stationary seal must be
smooth with no chips or cracks.
NOTE: 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 S).
7. Remove drip tray and empty contents.
8. Take all components to the cleaning area.
9. Prepare 1 gallon solution of hot tap water and a good grade of dishwashing detergent.
10. Thoroughly wash all components in a warm, mild detergent solution 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. (Figure T)
12. The exterior of the freezer should be cleaned as needed with a cloth towel.
CAUTION: Coarse rags, abrasive cleaners and excessive force can
damage and/or scratch the surfaces of the freezer.
Reassembly
NOTE: Allow all parts to dry completely before reassembly.
1. Reassemble drip tray and re-install on front of unit.
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 U). 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 V)
NOTE: 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 W. 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 X)
7. Inspect and lightly lubricate the large square o-ring
and refit it into the back of the valve block
assembly. Install the valve assembly on the front
studs and tighten the knobs until they are finger
tight. Do not use tools to tighten knobs.
NOTE: Failure to lightly lubricate the large o-ring can
result in product leakage.
