Grindmaster 6321L Alcohol Ratio Check, Checking Unit for Syrup, CO2, and Water Leaks

Checking BRIX (Water-to-Syrup Ratio) of Dispensed Product (cont’d)

6) If the volume is not 3.7 oz. (110 ml), consult the Troubleshooting Guide in this manual.

Note: Due to the thick viscosity of the syrup, it may be necessary to purge the syrup line to obtain an accurate flow rate reading. Purge the syrup line by first closing the syrup valve, opening the water valve and then momentarily turning on the test switch. This will purge all syrup from the lines and allow them to drain properly for a correct reading of the syrup flow rate.

7)After the correct water and syrup flow rates are set, open both the water and syrup valves.

8)Turn the "TEST" switch to "ON".

9)Dispense mixed water and syrup though the test line.

10)Check the BRIX of the mix using a refractometer. Verify that the solution has a BRIX reading of 15.

Alcohol Ratio Check:

1)Close all manual valves except for "ALCOHOL".

2)Put test outlet port tube into the graduated cylinder.

3)Toggle "Sample Timer" test switch to "ON". Product will flow for 10 seconds.

4)When flow stops, measure volume in the graduated cylinder. The proper setting is 3.4 oz. (100ml).

5)If the volume is not 3.4 oz. (100ml), consult the Troubleshooting Guide in this manual.

Checking Unit for Syrup, CO2, and Water Leaks

After checking all the ratios, open all manual valves. Open the cabinet's front and rear doors and check for any leaks. If any leaks are located, contact an authorized service technician to fix the leak. Close and lock the front and rear doors.

Defrost Timer

Setting Clock (Time of Day)

1)The timer is located inside the freezer back lit merchandiser box on the top front of the freezer. (Figure 11)

2)Rotate the timer dial, in the direction of the arrows, until the mark lines up with the current time of day.

3)The timer has a 2 week battery backup that requires 24 hours to charge fully.

Programming Defrost (Automatic)

1)Push all switch pin actuators toward the outer edge of the programming disk.

2)Set freeze time by pushing the switch pin actuators toward the center of the programming disk. (Figure 11) An adequate defrost cycle should last 3-1/2 hours.

Note: Each pin actuator is equivalent to 15 minutes. Do not run a defrost for more than 4 hours. May result in damage to seals.

Figure 11

Filling Freezer

1)Open all product manual control valves.

2)Set lower control box Power switch to "ON" and Sample Timer switch to "OFF" and Control Select switch to “Run". (Figure 10)

3)Fill freezer with product

a.Turn freezer to "CLEAN", barrel will fill

b.When BIB pump stops switch freezer "OFF"

c.Open dispensing relief valve vent and relieve pressure. Close vent.

d.Repeat steps a-c until product reaches vent opening.

4)Switch freezer to "FREEZE" and allow approximately 15 minutes for product to reach proper frozen consistency.

NOTICE: For applications with extended periods between use (i.e. stadiums, arenas, special events) the freezer must remain in “FREEZE” mode at all times, with a programmed defrost cycle. Turning the freezer “OFF” or unplug- ging it with product in the cylinder can damage the seal, resulting in product leakage. If the freezer must be unplugged or turned “OFF”, for a period of time exceeding 12 hours, it must be drained, cleaned and sanitized. Contact a qualified service technician, such as ICEE Company, phone (800) 423-3872, to perform this service. Freezer damage resulting from failure to follow this procedure is not covered under warranty.
