Hoshizaki KM Cubers Training: Part 3

Hoshizaki KM Cubers Training: Part 3

This video will demonstrate the proper way to perform the 10 minute check-out procedure for a system diagnosis of the KM cuber. Before we see how to diagnose electrical and component failures, let’s review the KM cuber’s sequence of operation. First, the unit always starts in the 1 minute fill cycle. Sixty seconds later, the initial harvest begins. Three to four minutes later, the freeze cycle begins. Longer harvest may occur in colder climates. After an average freeze time of approximately 30 minutes, the pump-out cycle occurs. Ten to twenty seconds later, the normal harvest begins. The KM cuber will continue to cycle until the bin control opens to stop the ice production. The first step in the 10 minute check-out procedure is to make sure there is adequate water and power supplied to the unit. When trouble shooting for system failures, remove the front panel, turn the ice maker off, and remove the control box cover. Now turn the unit back on. Remove the evaporator cover and make sure water is entering the reservoir. If there is no water coming in, check the bin control. The bin control contacts supply power to all the other controls in the unit. To check the bin control, flip the unit switch to the “wash” position. In the pump starts, it indicates that the bin control is closed. Next, check the cleaning valve micro switch. Flip the unit switch back to the ice making position. If there is still no water entering the evaporator, check the position of the cleaning valve handle. This handle must be in the horizontal position in order for the micro-switch, located behind the handle, to close. This micro-switch supplies control voltage to the control board. The cycle will not start without control voltage. A quick check of the control transformer secondary will verify that control voltage is present. If the 1 minute fill does not begin after you have checked the bin control and cleaning valve, check for 115 volts to the water valve. Check the terminals of the inlet water valve. If you have voltage, you can assume there is a problem with the water valve. Before replacing the water valve, check the inlet stream for debris. To do this, shut off the water and unscrew the thumbnut behind the water valve. Push the water line aside and inspect the screen. Clean or replace the screen as necessary. Check the water valve coil and diaphragm for problems and replace the water valve if necessary. After correcting the water valve problem, turn the machine on. The ice maker should cycle through the 1 minute fill and start the initial harvest cycle. If the initial harvest cycle does not start after 1 minute, check the float switch. Unplug the float switch and check for continuity with your own meter. If it is not closed and water is in the reservoir, the float switch is either dirty or defective. Clean it and check it to assure proper operation. If the float switch is good, the control board timer is defective and the board should be replaced. If the ice maker cycles into the initial harvest, the float switch is closed and the 1 minute timer works. A minute or so into the harvest cycle, the inlet to the evaporator should feel warm to the touch. As the hot gas circulates, the thermistor at the evaporator outlet reaches 48 degrees. The length of time it takes to reach 48 degrees depends on the ambient conditions and the water temperature. The length of harvest will automatically adjust to be longer in the winter and shorter in the summer. If the evaporator is not warming up, the first place to check is the hot gas valve. Lightly touch the discharge line to see if it is hot. If the discharge is not hot, then there is an obvious refrigeration problem and you’ll have to troubleshoot the system using basic refrigeration practices. If the discharge line is hot, but there is no heat coming from the outlet of the hot gas valve to the evaporator, you should check for coil voltage. To check for voltage, pull the tin pin connector out about 3/8” and check from the pin on the pink wire, which is the hot gas valve, to a neutral white wire. If you get proper voltage, the control board is working. If not, the problem is the control board. If you do get voltage, check the coil to be sure it’s energized. To do this, lay a metal paperclip on the coil. If you can feel a magnetic pull, the coil is energized. If the coil is in fact energized, it is possible that the hot gas valve is stuck. A stuck valve should be replaced using proper refrigeration practices. With normal operation of the hot gas valve, the evaporator will warm. At 48 degrees, the thermistor will start the defrost completion timer. The average harvest cycle and average ambient temperatures will range from 2-4 minutes. Longer harvest will occur with colder supply water or if the defrost completion timer is adjusted longer. If the harvest cycle does not end within 10 minutes, leave the machine running and unplug the thermistor. Check the resistance with your own meter and compare it against the temperature resistance chart in your tech specs book. For example, if your meter reads 6K ohms of resistance, the sensor temperature is 32 degrees. However, after 10 minutes in the harvest cycle, the temperature should be much warmer. This would tell you that there is a refrigeration problem. In another example, if your meter reads 2.5K ohms then the suction line temperature is 70 degrees. Since that temperature is well above the normal 48 degrees needed to start the defrost completion timer, the control board is not responding and there is a problem with the board. Once the harvest cycle ends, the freeze cycle begins. The hot gas valve and water valve de-energize and the pump motor and self-contained fan start. After the ice maker is in the freeze cycle, the evaporator inlet should feel cold within about 3 minutes. If it does, you have basic refrigeration occurring. If the evaporator is still warm after 3 minutes, there is a possible refrigeration problem. This problem might be caused by 1-hot gas valve not closing, 2- coil still energized because of a control board problem, 3- thermostatic expansion valve not opened properly, or 4- insufficient refrigerant. These items should be checked using normal refrigeration diagnostic practices. Next, let’s make sure the ice maker is purging properly by checking the pump-out system. After 5 minutes in the freeze cycle, unplug the float switch to initiate harvest. This will cause the unit to go into a 10 second pump-out that will flush the dirty water and sediment through the check valve and down the drain. You can also squeeze the pump supply hose tight enough to force the water down the drain. This would empty out the reservoir and allow the float switch to open by itself. It is important to understand the control components of the KM cuber. These components include the control board, the float switch, the thermistor, and bin control. First, let’s look at the bin control for any suspected problems or adjustments. A quick check of the bin control can be accomplished by switching the pump to the “wash” position. The unit will not start if the bin control is stuck open. When the bin control is stuck closed, the machine will not automatically shut off. If the bin control is not adjusted properly, it could cause the unit to shut down prematurely or allow ice to back up into the evaporator, causing a freeze-up condition. To check the adjustment of the bin control, access the thermostatic bulb, turn the switch to the “wash” position. Next, place a small amount of ice on the thermostatic bulb. Count the seconds and listen for the pump to shut off. If the pump shuts down within 6-10 seconds, the bin control is adjusted properly. Adjustment can be made with a screwdriver in the bin control slot. The float switch has two primary functions; it provides low water safety protections and initiates harvest. If the float sticks in the down position, which is open, the unit will switch to the one minute fill cycle and run water continuously. If the float sticks in the up position, which is closed, the unit will remain in freeze for 60 minutes. The cubes will be larger than normal and the pump will cavitate before harvest begins. If either of these symptoms exists, the float switch needs to be cleaned and checked. First, take the float switch apart and clean it with ice machine cleaner. Once you’ve cleaned the float switch, check it with an ohm meter to be sure it operates properly. The thermistor monitors the outlet temperature of the evaporator. At 48 degrees, it starts the defrost completion timer. At 127 degrees, it automatically shuts down the machine on the manual reset high-temperature safety. There are only two ways a thermistor can fail: open or shorted. An open thermistor will cause a consistent 20 minute harvest cycle. A shorted thermistor will shut the unit down on the high-temperature safety. When you switch the power off and back on, the safety will not reset. The thermistor should be checked using an ohm meter as previously discussed. Now, the control board. The control board processes information to supply the voltage that allows the components of the ice maker to cycle properly. Many things can affect the control board, but if you have proper supply voltage, proper control voltage, a good float switch, a good thermistor, and good pin connections, and the machine is not cycling properly, you can assume that you may have to replace the control board. Remember, when servicing any Hoshizaki ice maker, always refer to your tech specs guide for detailed information or call the Hoshizaki service hotline on your screen. Understanding these symptoms and the operation of these simple controls will help you diagnose sequence problems on a KM unit using the 10 minute check-out procedure.

Hoshizaki Ice Types

Hoshizaki Ice Types

Hoshizaki is a global leader in the design, manufacturing, and marketing of equipment for the food service industry. Award-winning products combined with an extensive sales and service network make Hoshizaki the right choice. Hoshizaki stands out from the completion in three key areas: 1. Stainless steel exterior throughout our entire product line, 2. Stainless steel ice-making surface, and 3. Individual cubes. Ice is one of the most important items served in any food and beverage operation. And if you don't think so, see what happens when you run out. Ice is no longer one size fits all. The latest trends show that operators are demanding a variety of ice to meet each site application. Perhaps it's the cube ice for beverages, or flaked ice for seafood displays; it's important to know which type of ice is just right. At Hoshizaki, we offer three styles of cube ice: our signature crescent cube, the IM square cube, and our AM gourmet cube (or "top hat" shape). Let's look at each type in more detail so you can determine how to specify "just right" for the operation. Our crescent cube has been called the world's most perfect ice for good reason. Our exclusive design produces a hard, pure, crescent-shaped ice cube. Cuber ice machines have features which differentiate it: the stainless steel flat ice-making surface is durable with long-lasting construction. This makes it easy to clean and produces clear, pure cubes. Individual square cubes are designed for the discriminating customer. These hard, large cubes are a favorite of mixologists for adult beverages and specialty drinks. Top hat-style cubes provide a hard individual gourmet ice. They are perfect for offices, residential, rooms or suites, outdoor kitchens, and healthcare. In the flake category, we offer the traditional fine-flaked ice and cubelets, a larger chewable ice. Ice is formed in a barrel-type cylinder, moved upward through an extruding head, producing a dry, flaked, or cubelet ice. Available in a wide variety of configurations, our cubelet ice offers fast cooldown with good displacement. It's a customer favorite because it absorbs beverage flavors, allowing them to linger on your taste buds. Popular in produce and seafood displays, as well as healthcare, our flaked ice is a moldable ice that quickly cools down and maintains freshness of foods. All Hoshizaki models have a stainless steel exterior, providing the perfect combination of sophistication and durability. Hoshizaki is Energy Star Partner of the Year. At Hoshizaki, our performance says it all. We rank the highest in efficiencies in our reported product categories for Energy Star. Hoshizaki: The right choice.

Hoshizaki Ice Machine Installation

Hoshizaki Ice Machine Installation

The purpose of this video is to demonstrate the proper installation of Hoshizaki ice machines. While the KM cuber and flaker machines differ in some features, the installations are basically the same. In order to avoid problems after starting up, it is important that you install these machines properly the first time. There are several things you should do before installing the ice maker. First, take a look at the installation site. Remember, these ice makers are not intended for outdoor use. For best results, the ice maker should not be located next to ovens, grills, or other high-heat producing equipment. The location should provide a firm, level foundation for the ice maker and storage bin. Check the installation site to be sure there's an adequate water supply and proper drainage. Be sure to allow for a 6 inch clearance at the rear, sides, and top of the machines intended location to allow for proper air circulation and ease of maintenance and service. If you are installing an auger type ice maker, it is necessary to allow for adequate clearance above the unit to allow for during service. Next, inspect the exterior of the cartons for visible damage and unpack the storage bin. Make sure it is the correct bin for your application. Attach the four adjustable legs provided to the bottom of the storage bin and position it in the selected permanent position. Then, unpack the ice maker, being careful to save the registration cards located in the pouch on the carton. Also, remove all packing material and tape from inside the machine and remove the package containing the installation manual and accessories. Always refer to this manual or your Hoshizaki technician's pocket guide and carefully follow the instructions for installing the ice maker. To prevent damage, remove the outer panels before installing the ice maker. Now, check to see that the refrigerant lines do not rub or touch other line surfaces. On air cooled units, be sure that the fan blade turns freely. Check that the compressor is snug on all mounting pads. Finally, check the name plate to make sure that your electrical service is the same as the voltage specified. The gasket provided with the Hoshizaki bins provides an adequate seal between the two units. Place the ice maker on top of the storage bin and secure it by using the two mounting brackets and four bolts provided. Level the ice maker storage bin in both the left to right and front to rear directions using the adjustable bin legs. If you're stacking two S units on a single bin, remove the top panel and ABS evaporator cover from the lower unit. Set the second unit on top and secure it with the brackets provided in the accessory package. Remove the bin control holder and bulb from the top bracket and round it to the bottom unit bracket, taking care not to touch the suction or discharge lines or the compressor base with the controlled capillary tube. Use the top bulb holder to secure it to the bottom bracket. Plug in both bin control plugs and be aware that Hoshizaki stacked units operate independently of each other. When making the electrical connections, it is important that they be made in accordance with the instructions on the warning tag provided with the leads in the junction box. Make sure the white leads are connected to the neutral conductor of the power source. To prevent possible electric shock or damage to the machine, be sure to install a proper ground wire to the ice maker. On 208/230V single-phase applications, a dedicated neutral wire is required by national electrical codes. A separate power supply or receptacle is required for the installation of each ice maker. Be sure to check the name plate for proper capacity. On units requiring the installation of a remote condenser, the unit must be installed in a permanent location. If the condenser unit supplied is not the appropriate Hoshizaki condenser, be sure that the application has been approved in writing by the Hoshizaki technical support department. The installation site should be firm and flat. The location should also be dry and well ventilated. This means locating the unit away from standing water and providing 24 inch clearance on both the front and rear of the unit. Also, when locating the condenser, keep in mind that the maximum refrigerant line length with a factory charge is 66 feet. This can be extended to a maximum of 100 feet with an additional charge. Consult the manual for recommendations for line size and charge amounts. To install the remote condenser unit, first remove it from the carton and secure the legs squarely with eight M8 by 16 mm hexagon bolts and M8 nuts. Next, secure the legs to the roof curb with eight bolts in the eight mounting holes. When installing two remote condenser units, you may stack them to save space. Attach the upper condenser unit on top of the lower unit and secure it with the four screws provided. When installing two copper tubing sets between the ice maker and condenser units, take extra care to mark the refrigerant lines and electrical connections. This will assure that they will not get crossed during installation. Each copper tubing should be sized properly and insulated separately. Pre-charged tubing kits are available from Hoshizaki America in 20, 35, and 55 foot lengths. Line sets fabricated on the job should be evacuated through the charging ports on the Aeroquip couplings and charged with refrigerant vapor to a pressure of 15 to 30 PSIG. Pre-charged tubing kits do not need to be evacuated. To connect line sets to the ice maker and condensing units, remove the plastic caps that connect the couplings and place a small amount of clean, dry refrigerant oil on the O rings and male threads on each connection. Connect the refrigerant lines with the proper-sized Aeroquip fittings to the connection of the condenser unit and ice maker. Then, tighten the fittings until they bottom out, and turn them 1/4 round more. This provides a leak free, brass to brass seal. The fan controlled wiring in the ice making unit requires a 3 wire circuit. To connect the circuit, first remove the panel and junction box cover from the condenser unit. This circuit should be routed through seal-tight conduit. A disconnect may be required by a local code. Connect the fan motor leads in the junction box of the remote condenser unit to the fan motor leads in the junction box of the ice maker. A proper ground wire is required to prevent possible electrical shock. The ice maker inlet water line must be sized correctly for proper operation. Check your manual carefully to be sure which size is required for the ice maker you are installing. Depending on the local water quality, the installation of an external filter with an adequate flow rate may be required for the ice making inlet. The water supply pressure should be a minimum of 10 PSIG and a maximum of 113 PSIG. If the pressure exceeds 113 PSIG, you will need to install a pressure reducing valve. On water cooled models, two separate water supply inlets are provided: one for the ice making inlet and the other for the water cooled condenser inlet. The drain outlet for the ice maker reservoir uses a 3/4 inch female pipe thread or FPT. The drain for condensation is a 3/8 inch ID pipe. Be sure the ice maker drain and the condenser drain piping connections are made separately from the bin drain. Hard piping with copper or PVC is recommended. On water cooled models, a separate 1/2 inch FPT connection is provided for the condenser drain outlet. All Hoshizaki ice makers should be installed in accordance to all applicable national, state, and local regulations. Also, a back flow preventer may be required by local codes. Now that you have installed the Hoshizaki ice maker, review the final check list provided in the installation manual. At the point that the list requires you to start the ice machine, flush the water system thoroughly and check the unit for proper operation. Check the bin control switch for correct operation and position. This can be accomplished by holding an ice cube in contact with the bulb while the ice maker is running. The machine should stop within six to ten seconds. Once the installation is complete, carefully score the edges of the protective plastic film and peel the film from the exterior panels. Make sure to give the end user the instruction manual and review the operation of the ice maker, stressing the importance of performing the recommended periodic maintenance. Also, be sure to give the end user the name and phone number of an authorized service agent. Remind them to fill out the warranty tag and forward it to the factory for warranty registration. Once you have successfully completed the check list, you can be sure that the Hoshizaki ice maker is installed correctly and will avoid the unnecessary problems that sometimes occur due to improper installation. Remember, while this video has shown you the proper installation procedures, you should always refer to the ice maker manual or your Hoshizaki technician's pocket guide for detailed installation information.

Hoshizaki Ice: The Most Important Ingredient in Drink Making

Hoshizaki Ice: The Most Important Ingredient in Drink Making

I'm Jenner Cormier, We're here today at our beautiful bar, Isabelle, going to make you guys a few drinks with Hoshizaki ice, our preferred choice. We're going to start with some chocolate bitters, going to add in 2 dashes of those. Followed by some fresh meyer lemon juice, and a barspoon of homemade yellow plum jam. You could substitute in just about anything, in this case. Anything seasonal, anything with some nice sweetness, some nice brightness. That'll act as our sweetening agent as well. We're going to add a little bit of fresh mint, just going to use some of the leaves, leave that sprig for garnish. We're going to add some overproof bourbon, a nice healthy ounce. Followed by an aromatized wine, full French. So we're going to add some ice in here, give it a good shake. Today, we're lucky enough to be using Hoshizaki's crescent cube, which is going to give us a really nice chill on the drink without over diluting. Now we're going to fine strain this into a chilled glass. See we don't have many ice shards? It's that wonderful, dense, crescent cube we used. Going to quickly chill down our mixing vessel, with this wonderful 1" cube from Hoshizaki. We're going to jump right in, 2 dashes of bitter truth Jerry Thomas bitters, followed by a healthy half ounce of moscow, we will follow that up with a nice artichoke flavored amaro. Tie that drink together with Plantation's pineapple rum. So we're stirring this drink with Hoshizaki 1" cubes, they're nice and dense, so we're going to get a really wonderful chill with just the right amount of dilution that we're looking for. We're going to strain that into a nice, chilled, old fashioned glass, and we're going to express an orange zest over the surface of the drink. I think that far too often, ice is overlooked as a main ingredient in drink making. You can depend on Hoshizaki's ice to produce a consistent, final product.
