Product Consistency Adjustment (cont.)

4)When making adjustments to a thicker (colder) setting, dispense approximately 16 ounces (1/2 liter) of product and recheck consistency after the compressor has cycled off.

5)If the consistency is still not correct, repeat steps 2 and 3.

"Standby" - Freezing Cylinder Temperature Adjustment

1)Remove the front electrical box cover. (See Figure C).

2)For a colder setting, turn the "Barrel" control adjuster, located at the top left of the circuit board, counter clockwise. (See Figure I).

￿CAUTION: This control setting is very sensitive so always make small adjustments. If you visualize this control as a clock face, a one-hour change will make noticeable difference in freezing cylinder product temperature. A recommended setting is 11:00.

Hopper Temperature Adjustment

1)Remove the front electrical box cover.

2)For a colder setting, turn the "Hopper" control adjuster, located at the top left of the circuit board, counter clockwise. (See Figure I).

￿CAUTION: This control setting is very sensitive so always make small adjustments. If you visualize this control as a clock face, a one-hour change will make a noticeable difference in hopper product temperature. A recommended setting is 10:00.

Note: Some models will have a built in feature (in the freeze mode) that will make the machine inoperable if the mix gets low and is not refilled after ten minutes. (The normal sequence is five beeps every two minutes for a total of ten minutes, then shut down occurs until the unit is refilled). These same units will also have a forty-five second dasher run time after the compressor turns off.

Consistency Control - Overview

￿CAUTION: SHOCK HAZARD

THIS ADJUSTMENT REQUIRES REMOVAL OF THE ELECTRICAL BOX COVER AND SHOULD BE MADE BY A QUALIFIED SERVICE TECHNICIAN.

The “freeze” mode consistency setting adjusts the frozen product thickness. In the “freeze” mode, as the liquid mix in the cylinder freezes, it becomes harder for the motor to turn the dasher assembly. The control board senses the amount of energy that the drive motor consumes as it rotates the dasher assembly through the product in the cylin- der. The control board will turn the compressor and barrel solenoid valve off at the proper consistency. The drive motor will continue to run for 45 seconds after the compressor is cycled off. This is called the blending cycle. After the blending cycle is complete the drive motor also is shut off. The drive motor and compressor will run together at any time refrigeration is required in the barrel. The compressor will run independently for the hopper if required. The hopper is controlled by temperature. The thermistor will signal the board and the board will start the compres- sor and open the hopper solenoid valve.

The unit will remain off until either the timer in the control board (either 10 or 15 minutes dependent upon which value is selected) restarts the drive motor. In this case the drive motor will run for 45 seconds and if no refrigeration is required the drive motor will then shut off. If refrigeration in the barrel is required the freeze cycle is repeated as well as the blending cycle. The unit will also restart the drive motor if the plunger is raised. The plunger switch will start the drive motor and remain on as long as it is held open. After the plunger is closed, the drive motor will con- tinue to run for 45 seconds. The compressor will start, and barrel solenoid valve will open. If refrigeration is required during this time the freeze cycle and blend cycle will follow.

The Grindmaster 5711, 5941, 5311, and 5511 series of coffee grinders have emerged as prominent tools for coffee enthusiasts and professionals alike. Known for their durability and precision, these grinders offer a range of features that cater to various brewing methods and preferences.

At the heart of each model is a set of high-quality, stainless-steel burrs designed for consistent grind size. Burr grinders, as opposed to blade grinders, provide uniformity in particle size, which is essential for optimal extraction and flavor in coffee brewing. The Grindmaster series employs advanced grinding technology that minimizes heat transfer, preserving the delicate oils and aroma of the coffee beans during the grinding process.

One of the main features across these models is their user-friendly interface. They are equipped with intuitive controls, allowing users to easily adjust grind settings to achieve the desired coarseness or fineness. The 5711, for instance, is celebrated for its precision adjustment system, enabling users to fine-tune their grind settings for varying brewing methods, from espresso to French press.

Another noteworthy characteristic is the incorporation of an efficient motor that not only ensures smooth operation but also enhances durability for long-term use. These grinders operate quietly, making them suitable for environments where noise reduction is essential, such as coffee shops or homes with open layouts.

Safety and convenience features are also integral to the Grindmaster series. Most models include a safety lock to prevent operation while the grinder is being cleaned or adjusted. The removable grinding chamber makes it simple to clean and maintain the equipment, extending its lifespan and ensuring consistent quality.

The design of the Grindmaster grinders reflects both functionality and aesthetics. Their sleek and modern appearance fits seamlessly in both commercial settings and home kitchens. The robust construction withstands daily wear and tear, making them a reliable choice for frequent use.
