FREEZER APPLICATION AND SPECIFICATIONS

Model 3511

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 an air-cooled refrigera-
tion system to freeze the product. A self-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 3511 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 3511 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 locat-
ed 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 inconsis-
tency. Simply keeping the product, in the mix storage hopper, stirred on a regular basis will eliminate this problem.
