Important Failure to closely follow operational and maintenance procedures may result in damage to the unit and/or void your warranty. Coldelite Corporation will not be responsible for any machine not properly maintained. In the event this unit should malfunction, please contact your Coldelite Distributor or an authorized service agency.
The compressor is also internally protected. If the Klixon protector trips due to an overload, again the protector must first cool down for several minutes before the compressor can be restarted. C) Electrical Requirements All wiring installed to operate this freezer must be in accordance with the National Electrical Code and/or local electrical codes, rules and regulations. The machine must be properly grounded. It is recommended the power supply be installed by a licensed electrician.
Stand-by function This position is used during prolonged idle periods. The temperature of the product in both the mix tank(s) and freezer cylinder (s) is held at a safe temperature and controlled automatically by the thermostats. Product should never be served when in this position as the “storage” temperature is higher than normal serving temperatures.
B) THE DISPENSE HANDLE D) SAFETY SWITCH The Dispense Handle controls the flow, or extraction rate of finished, soft serve product. Machine is equipped with a magnet molded into the spigot head. If the spigot head is removed the magnet deactivates a safety switch behind the front panel. The machine will not operate with the spigot head removed. A message "MIP" will appear on the display. Pulling the handle in a downward direction will open the dispense orifice.
The following is an explanation of the control panel controls: F) OTHER CONTROLS 1) BEATER MOTOR STARTER - activates the beater/auger drive motor. In the "BEATER" mode, the starter is energized by the front switch pad. In the "AUTO" mode, the starter is activated by either the proximity switch or timer. 1) Refrigeration SOLENOID VALVES are located behind the left side panel.
Once removed, the tube must be disassembled. To disassemble, first remove the “SPLASH GUARD” by pulling it out of the tube. PART III INITIAL CLEANING PROCEDURE This is a new machine and it must be completely disassembled, washed, and sanitized before starting. Proceed, as follows: 1) Remove the mix tank cover and items packed in the tank (spare parts, sanitizer, lubricant).
4) Loosen and remove the two (2) dispensing head retaining knobs. The knobs are removed by turning in a counterclockwise direction. Finally, remove the o-rings using the O-RING EXTRACTOR included in the “start-up kit”. 5) Remove the dispensing head by pulling it straight towards you and away from the machine. Warning! Never use anything other than the O-RING EXTRACTOR to remove o-rings as damage to the o-ring and/or part can result. 3) Clean carefully the mix level device.
6) Disassemble the dispensing head by first opening the dispense handle. Using the O-RING EXTRACTOR, remove the piston o-rings. Each piston o-ring groove is notched for easy insertion of the oring extractor. Pull the handle retaining rod out far enough to allow the first handle to disengage. Turn the dispensing head over and remove the large o-ring from the back of the head. Return the retaining rod to its original position.
10) Wash all the parts in luke warm water (80-85 F) using a mild detergent and the cleaning brushes provided in the STARTUP KIT. 8) Disassemble the beater/auger by first removing the rubber beater shaft (lip) seal, simply slide it off the shaft. DO NOT USE HOT WATER ON ANY OF THE PLASTIC PARTS AS DAMAGE TO THE PARTS CAN RESULT. 4) Air Dry 3) Sanitize 2) Rinse 1) Wash Continue disassembly by removing the beater IDLER.
Mount the idler back. PART IV ASSEMBLING THE FREEZER Once the parts have been washed, rinsed and sanitized, the freezer is ready to be re-assembled. Prior to beginning the reassembly procedure, sanitize your hands by submerging in the sanitizing solution. Begin to re-assemble as follows: A) Assembling the Beater/Auger 1) First, re-assemble the beater/auger assembly.
Rotate the beater/auger until you feel the drive shaft engage and push the beater/auger further back to properly seat. 6) Finally, insert the beater/auger into the freezer cylinder. Holding the beater/auger horizontally, slide it straight into the cylinder until it can go no further. IMPORTANT: Before installing the beater/auger, make certain the beater lip seal is in place and the idler is properly installed.
2) First, remount the end piston O-rings onto the end pistons. Simply roll onto the piston until they drop into the O-ring notches. 4) Insert the piston into the chamber of the dispensing head body making certain to align the square notch of the piston with the rectangular notch at the front of the dispense head. 3) Once the O-rings have been mounted, liberally lubricate the area between the two O-rings. Place a bead of lubricant around the entire piston as shown.
6) Affix the dispensing head to the machine and fasten it onto the two mounting studs. C) ASSEMBLING THE GRAVITY FEED TUBES 1) Begin by gathering the parts needed to assemble the gravity feed tube. These parts include: A) the SPLASH GUARD, B) two (2) 3/4" diameter O-rings, C) the TUBE SLEEVE, and D) the GRAVITY FEED TUBE. D B C A 7) Fasten the dispense head to the machine using the two (2) stainless steel retaining knobs.
3) Slide the sleeve onto the tube. Please note that the slots in the sleeve should be at the top of the tube when installed. 4) Slide the splash guard into the tube. The machine is now completely assembled and ready to be sanitized. PART V SANITIZING THE FREEZER Prior to install the machine with your soft serve product, the machine must be sanitized. The frequency of cleaning and sanitizing cycles must comply with local health regulations.
4) Push selector button 571.1 to turn “OFF” the machine. 1) Mix the sanitizer (2 ounces of Steera Sheen green label or equivalent) into a clean pail containing one gallon of warm water. This solution will make a 200 P.P.M. (parts per million) concentration of chlorine sanitizing solution. Pour the solution into the mix tank. 571.1 IMPORTANT: Do not exceed the formula recommended by the sanitizer manufacturer as it will not add to its effectiveness.
7) Allow the sanitizer to completely drain. Close the handle. HELPFUL SUGGESTION: When the sanitizer stops flowing, leave the handle open. Push selector button 571.2 to select the BEATER position. Let the machine run for three, four seconds to help remove the last of the sanitizer. CAUTION: We recommend the beater/auger be turned as little as possible during the washing and sanitizing operations. Excessive use will cause premature wear to the beater/auger and cylinder.
2) Insert gravity feed tube(s) into the hole(s) at the bottom of the mix tank. PART VI STARTING THE FREEZER Only after the machine has been thoroughly cleaned and sanitized is the unit ready for production. Start the machine as follows: 1) Fill the tank with mix. Total capacity is 6 qts each. never fill the tank higher than the top of the gravity feed tube sleeve (See the illustration on next column).
MIX TANK REFRIGERATION 5) When this function is on, pilot light L2 lit, the product is cooled down until it reaches the proper consistency according to the HOM calibration. During this function the monitor displays a number indicating the consistency of the product in the cylinder until it reaches the set value, then indicates the temperature of mix in the hopper. Initial freeze-down will take 7-10 minutes depending on the type of mix used.
Dispense the ice cream without exceeding the machine’s production rhythm as indicated in the table on page 28. If you do not exceed this pace and are careful to refill the machine with fresh mix, you can be sure you will never have to pause in selling ice cream, even during peak times. PART VII OPERATING THE FREEZER The machine will automatically shut-off when the product has been frozen to the pre-set “consistency”.
GRAVITY FEED VALVE - HOW TO OPERATE AND MAKE ADJUSTMENTS The plunger/splash guard keeps the mix. from splashing on the mix tank cover and serves as a device to eliminate potential clogging inside the tubes. The Gravity Feed Valve consists of two tubes, one sliding inside the other, and a plunger/splash guard. You may find it necessary to adjust the position of the outer tube in order to regulate the amount of mix entering the freezing cylinder after start-up.
3) Place a container or bucket under the spigot head. Slowly pull the handle down and remove remaining product from the cylinder. PART VIII ROUTINE, PERIODIC CLEANING PROCEDURES Cleaning and sanitizing schedules are governed by your State or local regulatory agencies and must be followed accordingly. A well planned cleaning schedule will eliminate excessive waste of time and product within your organization. On a designated day(s) of the week, allow the mix in the mix tank to run as low as feasible.
IMPORTANT: Operate unit only in the BEATER position when cleaning. Do not operate unit for excessive periods in the BEATER position, one minute intervals per rinse is recommended. PART IX TECHNICAL INFORMATION UC 511 7) Brush all surface areas, with brushes provided, to remove all mix particles.
D) PROXIMITY SWITCH PART X MAINTENANCE The sensitivity can be adjusted with a small screwdriver. The trimmer rotation is limited to 270 degrees by a “stop”. When adjusting towards “maximum” or “minimum”, be careful not to exert excessive torque (max. 40 Nmm) against the “stop”. Failure to do so would damage the trimmer permanently. Your COLDELITE machine has been designed, engineered and manufactured to achieve high performance and long durability.
