WARNING LABELS AND SAFETY PRECAUTIONS OPERATOR'S SAFETY PRECAUTIONS 1. 2. 3. Read and understand the operating instructions in this manual thoroughly. Note all warning labels. If any of the warning labels are missing or damaged replace them immediately. Keep operating area clean. Located on the top of the condenser shroud and on the rear panel. INTRODUCTION The GRINDMASTER CORPORATION dispenser is a unique, self contained, counter top style unit with high capacity self-adjusting cooling systems.
INSTALLATION Installation Notice A water filter is recommended for the water supply to the dispenser, especially in areas where water contains a high level of minerals such as calcium or other solids. Over long periods of time, calcium deposits build on heat-exchanger coils and will lower the cooling capacity of the system. Calcium build up will also occur on the strainers enclosed in the dispensing valves. The cooling system is provided with copper coils, designed to last the life of the dispenser.
WARNING: Only a qualified service technician should service internal electrical components. Installing Your Unit (cont.) 4. Water Hook-up. It is recommended to provide water connection to the dispenser from a dedicated water line.

correct value with the use of a refractometer. Setting brix by taste is an acceptable method and usually gives + 0.5-0.8 brix error. Brix Setup (cont.) Mixing water with a concentrate in this dispenser was designed at the following conditions: 1. The initial temperature of a concentrate (syrup) used in the dispenser should be 39-41ÞF (4-5°C). 2. The initial temperature of the water supplied by the dispenser cooling system is 39ÞF (4°C). 3. The static water pressure should be set to 29PSIG.
Once the brix is set, use the same flavor set up on each dispensing head. The flavor used on a particular dispensing head can be changed if the brix and viscosity of the syrup remains the same. Dispenser Operation Tips 1. To dispense the drink, depress and hold dispensing push button as long as needed. 2. After dispensing 2 liters consecutively allow a 15-30 second idling time before next usage. 3. Keep dispenser door closed and do not allow it to be open for a longer time than necessary. 4.
