Accessory Inst
allation
The Model 3312 has several optional accessories that can be added
to the unit in the field to meet your application’s needs. These acces-
sories 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 - A private 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 8.
2. Fill the mix storage hoppers following the instructions on page 10. Allow
barrels 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 for each barrel.
4. Allow product to freeze in barrel. Compressor will turn off when product in
both barrels 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.
(The left-most light corresponds to the loft barrel.)
NOTE: Do not run the unit under mix low conditions for long periods of time. This
can affect machine performance or damage componentry.
