Section 6 Operating Procedures The C712 machine stores mix in a hopper. It has two 3.4 quart (3.2 liter) capacity freezing cylinders with a three spout door. Step 4 Apply an even coat of lubricant to the shaft. DO NOT lubricate the hex end. (See Figure 31.) We begin our instructions at the point where we enter the store in the morning and find the parts disassembled and laid out to air dry from the previous night's cleaning.
Step 8 Install the beater shoes. (See Figure 35.) Step 6 Before installing the beater assembly, check the scraper blades for any nicks or signs of wear. If any nicks are present, or if the blades are worn, replace both blades. If the blades are in good condition, install the scraper blade clips over the scraper blades. Place the rear scraper blade over the rear holding pin on the beater. (See Figure 33.) Figure 35 Step 9 Slide the beater assembly the rest of the way into the freezing cylinder.
Step 10 To assemble the freezer door, place the door gaskets into the grooves on the back of the freezer door. Step 11 Insert the prime plugs into the holes in the top of the freezer door, and push down. Figure 39 Figure 37 Step 12 To install the freezer door, insert the baffle rods through the beaters in the freezing cylinders. Slide the front bearings over the baffle rods. The flanged edges should be against the door. DO NOT lubricate the gaskets or front bearings.
Step 13 Slide the three o-rings into the grooves of each standard draw valve. Slide the H-ring and o-ring into the grooves of the center draw valve. Lubricate the H-ring and o-rings. Step 15 Insert the draw valves from the bottom until the slot in each draw valve comes into view. Figure 43 Step 16 Position each draw handle with the adjustment screw facing down. Slide the fork of each draw handle into the slot of each draw valve, starting from the right.
Step 17 Slide the pivot pin through the draw handles as the handles are inserted into the draw valves. Step 18 Snap the design caps over the bottom of the door spouts. Figure 45 Note: This freezer features three adjustable draw handles to provide portion control, giving a better consistent quality to your product and controlling costs. The draw handle should be adjusted to provide a flow rate of 5 to 7-1/2 oz. (142 g. to 213 g.) of product by weight per 10 seconds.
Step 3 Apply a thin layer of lubricant to the inside of the pump cylinder at the retaining pin hole end. (See Figure 51.) Step 20 Install the front drip tray and splash shield under the door spouts. (See Figure 49.) Figure 51 Figure 49 Step 4 Insert the piston into the retaining pin hole end of the pump cylinder. (See Figure 52.) Mix Pump Assembly Step 1 Inspect the rubber pump parts. O-rings and gasket must be in 100% good condition for the pump and entire machine to operate properly.
The adapter must be positioned into the notch located at the end of the pump cylinder. Step 6 Slide the pump valve gasket into the holes on the cap. DO NOT lubricate the gasket. (See Figure 54.) Step 9 Secure the pump parts in position by sliding the retaining pin through the cross holes located at one end of the pump cylinder. (See Figure 57.) Figure 54 Step 7 Insert the valve body cap into the hole in the mix inlet adapter. (See Figure 55.
Step 14 Install the hex end of the drive shaft into the drive hub at the rear wall of the mix hopper. (See Figure 61.) Step 11 Install one red o-ring on each end of the mix feed tube, and thoroughly lubricate. (See Figure 59.) Figure 61 Note: For ease in installing the pump, position the ball crank of the drive shaft in the 3 o'clock position. Figure 59 Repeat these steps for the other side of the machine.
Note: You have just sanitized the mix hopper and parts; therefore, be sure your hands are clean and sanitized before going on in these instructions. Step 3 While the solution is flowing into the freezing cylinder, take particular care to brush-clean the mix level sensing probe, the mix hopper, the mix inlet hole, the air/mix pump, the pump clip, the mix feed tube, and the cotter pin. Step 4 Install the pump assembly at the rear of the mix hopper.
Step 11 With an empty pail beneath the door spouts, raise the prime plug and touch the PUMP symbol Note: The brush clean counter will start at this time. Step 6 Fill the hopper with fresh mix and place the mix hopper cover in position. . Step 12 When a steady stream of sanitizing solution is flowing from the prime plug opening in the bottom of the freezer door, open the draw valve. Momentarily open the center draw valve to sanitize the center door spout. Draw off the remaining sanitizing solution.
Step 3 When a steady stream of rinse water is flowing from the prime plug opening in the bottom of the freezer door, open the draw valve. Drain all the rinse water from the door spout. Close the draw valve and push the prime plug down. Rinsing Step 1 Pour two gallons (7.6 liters) of cool, clean water into the mix hopper. With the white hopper brush, scrub the mix hopper and the mix level sensing probe. Using the double ended brush, brush clean the mix inlet hole. (See Figure 65.
Step 4 Disassembly Touch the WASH symbol . This will cause the cleaning solution in the freezing cylinder to come in contact with all areas of the freezing cylinder. Wait at least 5 minutes before proceeding with these instructions. (See Figure 67.) MAKE SURE THE POWER SWITCH IS IN THE “OFF” POSITION! Failure to follow this instruction may result in severe personal injury from hazardous moving parts.
Step 7 Remove the two small o-rings and one large o-ring from each pump drive shaft. Step 3 Return to the freezer with a small amount of cleaning solution. Using the black brush, clean the rear shell bearing at the back of each freezing cylinder. (See Figure 70.) Step 8 Remove the front drip tray and splash shield. Step 9 Remove all drip pans. Take them to the sink for cleaning. (See Figure 69.) Figure 70 Step 4 Using the black brush, clean the drive hub opening in the rear wall of each mix hopper.
Section 7 Important: Operator Checklist j 7. Discard remaining mix from the freezer during “Cleaning Procedures”. During Cleaning and Sanitizing ALWAYS FOLLOW LOCAL HEALTH CODES. Regular Maintenance Checks j 1. Replace scraper blades that are nicked or damaged. Before installing the beater assembly, be certain that scraper blades are properly attached to the helix. Cleaning and sanitizing schedules are governed by federal, state, or local regulatory agencies, and must be followed accordingly.
Winter Storage If the place of business is to be closed during the winter months, it is important to protect the freezer by following certain precautions, particularly if the building is subject to freezing conditions.
