FREEZER APPLICATION AND SPECIFICATIONS

Model 331

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.

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” Legs)

2. Make sure freezer is to be placed in a location that is within 6’ of a properly grounded circuit and allows adequate space at each side and above for proper air circulation. Air Cooled Units Only: Minimum clearance is 6” (15 cm) on both sides and 0” at back and open above the freezer. (See Figure C) Water Cooled Units Only: 3 -6” of clearance are required at the rear of the unit, 0” of clearance are required on both sides and open at top.

NOTE: Failure to allow adequate ventilation will void the warranty and reduce freezer performance. NOTE: 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 and supporting all four sides, lift machine up (by the frame) and place in appropriate area on top of rubber pad.

CAUTION: If equipped with spinner do not lift unit up by spinner shaft. It

will cause serious damage to spinner.

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.

4. The side panels should still be removed. Cut the cable tie used to secure motor during shipment. Make sure motor rocks freely. (Figure D)

5. Water Cooled Units Only: Hook water to inlet (3/8” flare fitting). Hook the drain line to the fitting on the out port. The out port will go to a drain or recirculating pump (reservoir with recirculating pump is recommended).

6. 220V/50Hz Units: These units come with a plugless cord that requires the appropriate plug configuration be connected. This must be determined by the power outlets at the specified location. See wiring diagram at back of manual for assistance. It is recommended that a service technician performs this operation.

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 drink headers including: frozen beverage, frozen lemonade, cappuccino, 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.

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. 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 maintenance ie. lubrication, filter cleaning, etc.).

• Make sure store personnel have appropriate supplies (lubricant, cleaning brushes and sanitizer) to care for machine.

How to Clean Condenser (Air-Cooled Unit Only) NOTE: Loss of refrigeration efficiency will result if condenser is allowed to become dirty. Excessive compressor run

time or loss of capacity are a good indication that the condenser needs to be cleaned.

1. Disconnect electrical power.

2. Remove side panels.

3. Place a damp towel over the side of the condenser opposite the fan motor.

4. Use compressed air or CO2 blow out dirt from the fan side of the condenser. An alternate cleaning method is to use a condenser brush and vacuum cleaner.

CAUTION: Procedure can create a loud noise.

How to Clean Exposed Filter (Air-Cooled Unit Only)

1. Slide exposed filter out of the rails by pulling forward on the filter. It is recommended to remove the filter by using the palm of your hand and applying even pressure to the face of the filter.

2. Clean filter with liquid soap and water.

3. Soak filter for 15 minutes.

4. Rinse filter with heavy stream of water, opposite the direction of air flow. Allow filter to dry.

5. Slide the filter into the rails until the filter contacts the stop on the top rail.

How to Clean Concealed Filter (Air-Cooled Unit Only)

1. For concealed filters lift lid and pull up on filter tab to remove filter.

2. Clean filter with liquid soap and water.

3. Soak filter for 15 minutes.

4. Rinse filter with heavy stream of water, opposite the direction of air flow. Allow filter to dry.

5. Slide filter into top of filter cover with removal clip up and the air flow arrows facing the existing panel.

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” 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 FF)

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. 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.
