Single Dispensing Installations Dual Dispensing Installations (One Condenser, Two Dispensers) Suction Line -- Less than 75 ft. (22.8 m) total line length requires 5/8” refrigerant grade copper tubing (hard or soft). Maximum 5/8” tubing length is 75 ft. (22.8 m). Individual Suction Line -- Requires 5/8” refrigeration grade copper tubing (hard or soft) from each dispenser to the common suction tube. Common Suction Line -- Requires 3/4” refrigeration grade copper tubing.
Installation Step 5 Evacuate the field constructed refrigerant lines using the access fittings brazed on the condensing end of the refrigeration lines. Step 1 Install refrigeration lines from the dispenser to the condensing unit. Do not create oil traps. Step 6 When the evacuation process is complete, relieve the vacuum with 4 oz. (113 g.) of HP62 refrigerant per line, for a total of 8 oz. (227 g.
Step 6 Check all connections for leaks. Step 6 Allow the dispenser to run until the condensing unit cycles off. Verify the proper pump down pressure switch setting. See Step 8 of “Refrigeration Connections” (page 6). Step 7 Insulate all exposed suction line tubing and fittings. Step 8 Set the pump down switch located in the condensing unit. For indoor condensing unit application: Note: Pump down pressure readings are to be taken at the refrigeration line access fittings near the condensing unit.

Section 5 Important: To the Operator Figure 3 Control Switch Mix Out Light The control switch is located on the front of the machine. The center position is “OFF”. The down position is the “WASH” mode and activates the beater motor only. The up position is the “AUTO” mode. The “AUTO” mode activates the beater motor and enables refrigeration when the fill switch is in the “ON” position. A mix out indicating light is located on the front panel.
Section 6 Operating Procedures We begin our instructions at the point where the parts are disassembled and laid out to dry from the previous night’s cleaning. Slide the seal over the shaft until it snaps into the groove. Fill the inside portion of the seal with lubricant and evenly lubricate the flat side of the seal that fits onto the rear shell bearing. The following procedures will explain how to assemble the parts into the freezer, sanitize them, and prime the freezer with fresh product.
Step 2 Install the beater assembly. First check scraper blades for any nicks or signs of wear. If any nicks are present or if the blade is worn, replace both blades. Figure 9 When in position, the beater will not protrude beyond the front of the freezing cylinder. Figure 7 If blades are in good condition, install the scraper blade clip over the scraper blade. Place the rear scraper blade over the rear holding pin (knife edge to the outside).
Insert the torque rotor (guide bearing end first) into the pilot hole in the center of the drive shaft. The hole in the torque rotor shaft should be rotated to the 12 o’clock position. Place the draw valve spring over the shaft end on the draw valve. Figure 14 Figure 12 Insert the draw valve and spring into the door spout until the threaded end of the shaft passes through the hole in the end of the door spout. Thread the draw valve knob onto the end of the draw valve shaft.
Place the large o--ring into the groove on the back side of the door and lubricate the installed o--ring. Place the door spout seal o--ring into the groove in the door and lubricate the components. Figure 16 Align the draw spout assembly with the door. Place the draw spout mounting plate over the draw spout assembly and align the holes. Figure 19 Place the door bearing onto the hub on the back side of the door with the flanged end of the bearing facing the door. Note: Do not lubricate the door bearing.
Step 6 Install the handscrews on the studs. Tighten the screws equally, using a criss--cross pattern. Do not overtighten the handscrews. Figure 23 Figure 21 Sanitizing Step 7 Install the torque arm. Position the torque arm by inserting it through the slot in the torque switch arm and down into the hole in the torque rotor which protrudes from the door. Verify proper installation by moving the torque rotor back and forth to be sure it moves freely and easily. Step 1 Fill System.
Place the control switch in the “WASH” position. Press the fill switch to activate the mix solenoid. The mix solenoid will remain open until the mix level float switch is satisfied. Drain sanitizer from the freezing cylinder and repeat this procedure until full strength solution is dispensed from the mix delivery container. Make sure all sanitizer is removed from the fill system. Place the fill switch in the “OFF” position and drain any remaining solution from the freezing cylinder.
Step 2 Dispenser. Prepare a pail of approved 100 PPM sanitizing solution (examples: 2--1/2 gal. [9.5 liters] of Kay--5R or 2 gal. [7.6 liters] of Stera--SheenR). USE WARM WATER AND FOLLOW THE MANUFACTURER’S SPECIFICATIONS. Remove the upper rear cover, and open the hopper cover. Pour the sanitizing solution into the hopper and allow the solution to flow into the freezing cylinder. Figure 32 Step 5 Place the control switch in the “OFF” position. Place an empty mix pail beneath the door spout.
Priming Step 1 With a mix pail beneath the door spout, open the draw valve. Press the fill switch to allow fresh product to flow into the freezing cylinder. This will force out any remaining sanitizing solution. When full strength product is flowing from the door spout, close the draw valve. Allow the freezing cylinder to fill until the mix level float switch has satisfied the fill system.
Rinsing Cleaning Step 1 Remove the upper rear cover, and open the hopper cover. Step 1 Prepare a pail of approved 100 PPM cleaning solution (examples: 2--1/2 gal. [9.5 liters] of Kay--5R or 2 gal. [7.6 liters] of Stera--SheenR). USE WARM WATER AND FOLLOW THE MANUFACTURER’S SPECIFICATIONS. Step 2 Pour the cleaning solution into the hopper and allow it to flow into the freezing cylinder. Step 2 Pour cool, clean water into the mix hopper and allow it to flow into the freezing cylinder.
Brush Cleaning Note: To remove o--rings, use a single service towel to grasp the o--ring. Apply pressure in an upward direction until the o--ring pops out of its groove. With the other hand, push the top of the o--ring forward and it will roll out of the groove and can be removed easily . Step 1 Prepare a sink with an approved cleaning solution in WARM WATER ACCORDING TO THE MANUFACTURER’S SPECIFICATIONS. Make sure all brushes provided with the freezer are available for brush cleaning.
