Do not use cigarettes, vapes, or cellphones near pipes or cables, as it can be a source of ignition or spark. This ice machine must not be installed next to equipment with an open ignition source (ie. open flames, an operating gas appliance, or electric heater). Do not store explosive substances such as aerosol cans with a flammable propellant in this appliance. WARNING: Do not use electrical appliances inside the food/ice storage compartments unless they are of the type recommended by the manufacturer. WARNING: In order to reduce flammability hazards the installation of this appliance must only be carried out by a suitably qualified person. This appliance must be installed according to the safety standard for refrigeration systems presented in ANSI/ASHRAE 15. Do not install next to anything that continuously vibrates, avoiding excessive vibrations or pulsations. Install in a well ventilated environment and ensure ventilation and outlets are not obstructed. Properly secure electrical wiring and cabling for the machine to minimize wear, vibrations, corrosion, excessive pressure, sharp edges, or other adverse environmental effects that could cause damage to wiring over time. Keep fire extinguisher nearby in case of emergencies. WARNING: Do not damage the refrigerating circuit Use a Scotsman recommended technician certified to repair R290 equipment. Install ONLY Scotsman factory service parts. Use of non-OEM parts can be dangerous due to the design changes needed to safely use R290 refrigerant. WARNING: Cancer and Reproductive Harm. Visit www.P65Warnings.ca.gov for details. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance. Caution: This equipment should only be used on ice bins without electrical components or bins designed to be used with flammable refrigerants. Safety Information WARNING: Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer. The appliance shall be stored in a room without continuously operating ignition sources Do not pierce or burn. Be aware that refrigerants may not contain an odor. All installation, service, maintenance and decommissioning to be carried out by technicians certified to handle FLAMMABLE REFRIGERANTS. Install in a well-ventilated environment and ensure ventilation and outlets are not obstructed. When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be used. However, for flammable refrigerants it is important that best practice be followed, since flammability is a consideration. The following procedure shall be adhered to: a) safely remove refrigerant following local and national regulations; b) purge the circuit with inert gas; c) evacuate; d) purge with inert gas; e) open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For appliances containing flammable refrigerants, the system shall be purged with oxygenfree nitrogen to render the appliance safe for flammable refrigerants. This process might need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems. For appliances containing flammable refrigerants, refrigerants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final oxygen-free nitrogen charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. Ensure that the outlet for the vacuum pump is not close to any potential ignition sources and that ventilation is available. Ensure that the leak detection equipment being used is suitable for use with FLAMMABLE REFRIGERANT; i.e., non-sparking, adequately sealed or intrinsically safe.

Consideration should be given to allow adequate space on the sides for air cooled models to breathe. Minimum clearance is 3 inches at the sides, none at the back and 2 inches above. The power outlet should be located within the length of the supplied power cord. Remove bolts holding machine to pallet. Use caution to not tip unit too far when removing bolts. Remove the protective plastic covering the panels. The longer it is left on the panel, the harder it will be to remove it. Air cooled models in a small room require ventilation to exhaust the heat they produce. They also produce some added noise from the fan. Nearby infrared emitters or a window that allows sunlight to shine on a dispensing sensor may cause the unit to dispense ice or water on its own. Wall mount units do NOT have a drip tray, so they MUST be positioned over a sink to collect any dripping water or spilled ice. Wall Mount These models are designed for mounting on a wall. Check building wall for the strength required to support a machine of this weight and size. Note that if at least 6" of space is not left above the machine, cleaning and most service of the machine will require removal of the machine from the wall mounts. All utilities are to be routed thru the base. One inch of space is needed between the wall and the back of the machine. Note: The wall must be plumb or the unit will be out of level front to back. Set Up It is a good idea to remove the front panels and inspect for any loose or rubbing parts prior to installation. It is recommended that the wall mounting installation be done by an experienced contractor. The weight of the machine when in use may exceed 350 pounds. The unit should be mounted on a solid, rigid wall with proper fasteners for that type of wall and of adequate strength to support the weight of the machine when in use. Unpack Panel Removal Remove one screw at bottom front of upper front panel, swing bottom of panel forward and lift off the unit. Twist ice and water chutes counterclockwise and pull down to remove. Separate the carton from the shipping pallet. Important: Locate and retain the wall mounting brackets, they were shipped in a box on the skid in front of the unit. Remove four screws from sides of splash panel, pull forward slightly. If needed, unplug sensor connector and separate panel from unit. Pre-Start Inspection Remove any strapping holding the cabinet to the pallet. Confirm there are no loose or rubbing parts. Inspect for hidden shipping damage. If any is found, retain carton and notify carrier for potential claim. Shipping damage is not covered by warranty. January 2025 Page 6 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Installation - Plumbing Installation should be done by an experienced ice machine installer. To locate one, call the number on the back of this manual or go to Scotsman's website www.scotsman-ice.com to identify a local distributor or service company. The machine will require power, water and drain. Locate the water supply fitting on the lower back of the cabinet and obtain the correct fitting to connect the water supply. Connect drain tubing to the 3/4 inch FPT central drain fitting at the back of the cabinet. Use 3/4 inch rigid tubing, use material to meet local codes. The drain basin in the machine will act as an internal vent, no additional vent should be required unless there is a very long horizontal run. Drain tubing must pitch down 1/4 inch per foot to the building drain. Insulation of drain tubing is recommended for most environments. Plumbing Fittings: Install Wall Mounting Brackets · Potable water inlet: 3/8 male flare. See next page for detailed instructions. · Cabinet drain: 3/4 FPT. Drain Tubing Potable Water Connection All models: Note: Wall mounting limits access to the utility connections which are at the back bottom of the machine. Pre-plumbing the water and drain is required so that stubs are available for final connection to water and drain. Connect the potable water supply tube to the 3/8 inch male flare inlet at the bottom back of the unit. Water filters may be used but are not required. Note that activated carbon or charcoal water filters are used for taste and odor problems but also take out any chlorine that the local water agency may have added for purification. That can require more frequent sanitization of the equipment. January 2025 Page 7 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Installation - Electrical Electrical Supply - 115 volt models Plug the unit into a dedicated 15 amp outlet. The unit must be the only device on the circuit. Confirm the outlet is properly grounded and is in good condition. Worn outlets should be replaced as they can cause erratic operation of equipment. Do not use an extension cord. Do not cut off the ground plug on the power cord. Ground fault outlets are not recommended. If ground fault is required, a ground fault breaker should be used. This ice machine should be installed on a dedicated circuit with a properly sized HACR-rated breaker or fuse. No other devices or appliances should be connected to the same circuit with the ice machine. Installing a unit on a shared circuit can cause product malfunctions or damage to the unit. The proper circuit size can be found on the unit data tag listed as "MAX FUSE OR HACR TYPE CIRCUIT BREAKER". Never allow the fuse size to exceed the maximum fuse size listed on the data tag. The use of a ground fault circuit interrupter (GFCI) or arc-fault circuit interrupter (ARCI) can lead to nuisance trips and is not recommended for use on most appliances, including our equipment. If local codes or other specifications require the use of ground fault circuit interrupters, a properly rated HACR GFCI or ARCI circuit breaker should be used. An outlet type GFCI or ARCI is not recommended for ice machines and other refrigeration equipment due to more frequent nuisance trips of the GFCI or ARCI. Always check with your local electrical inspector about the specific code requirements in your area for GFCI or ARCI breakers and GFCI or ARCI receptacles. Use the services of a licensed electrician when needed and conform to local and national codes. Follow All Local Codes - This Unit Must Be Grounded. Do not use extension cords and do not disable or by-pass ground prong on electrical plug. Use the services of a licensed electrician when needed and conform to local and national codes. Position the unit in its final location. Level the unit front to back and left to right. January 2025 Page 8 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Wall Mounting It is recommended that the wall mounting installation be done by an experienced contractor. The weight of the machine when in use may exceed 350 pounds. The unit must be mounted on a solid, rigid wall with proper fasteners for that type of wall and of adequate strength to support the weight of the machine when in use. 6. Use a mechanical hoist to lift the cabinet high enough to fit the flange of the machine bracket over the lip of the wall bracket. Then push it back and lower it onto the wall bracket. 7. Secure the wall and machine bracket with the bolts and lock washers originally used in shipment. The machine will have a bracket and there will be one bracket mounted to the wall. The machine will hang from the wall bracket by the upper bracket on the back of the cabinet. The lower bracket keeps the machine plumb to the wall. 1. Attach the water and drain tubing so the tubing extends below the bottom of the cabinet. That allows connection when the machine is on the wall. 2. Locate the box with the mounting brackets. Separate the two brackets. Retain the bolts and lock washers. 3. Identify the location of the wall studs or other materials to be used to fasten the wall bracket to. 4. Mount the wall bracket (has threaded inserts) to the wall using the appropriate methods and fasteners. Note: Must be level left to right. Bracket, mounts to back of dispenser. Bolt the two brackets together after unit is mounted. The wall bracket extends beyond the width of the machine to allow attachment to multiple wall studs. 5. Mount the other bracket to the back of the ice machine cabinet at the joint between the two back panels, using 9 existing screws in the back. Use cabinet screws to attach to back of unit. Bracket, mounts to wall. January 2025 Page 9 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Initial Start Up Final check list: 1. Is the icemaker-dispenser installed indoors, in a location where the air and water temperatures are controlled, and where they do not go beyond design limitations? 2. Is there an electrical disconnect (switch or plug as required) within sight of the installed machine? Is the machine on a separate circuit? Has the voltage been checked and compared to nameplate requirements? 3. Have all of the plumbing connections been made and checked for leaks? 4. Has the machine been leveled? 5. Is there a minimum of 6 inches of clearance at the left and right sides of an air cooled machine? 4. Push and release the ON/OFF button. The machine will start the ice making process. The code display will show F. Air cooled models will discharge warm air out the right side, water cooled models will discharge warm (about 110oF.) water out of the condenser drain. 5. Soon ice will begin to fall into the dispensing bin. Check ice dispensing by holding a container in front of the Touch Free ice sensor (just below the ice delivery spout). Ice should flow from the spout when a container is present, and stop dispensing when the container is removed. 6. Check water dispensing by holding a container in front of the Touch Free water sensor. Water will flow when a container is present and stop when it is removed. 6. Is there a minimum of 6 inches of clearance at the top of the machine for service? 7. Is there a water shut off valve installed near the machine? Start Up 7. Push the ON/OFF button to switch machine off. 8. Unplug or disconnect electrical power. 9. Remove the top panel and the top of the ice storage bin. Scoop out any ice in the bin and sanitize the interior of the ice storage bin by wiping it with a locally approved sanitizer or a mixture of 1 ounce of household bleach to 2 gallons of water. Allow to air dry. 10. Reconnect electrical power. ON / OFF 11. Push the ON/OFF button to switch machine on. 12. Replace all covers and panels. 13. Give the owner/user the user manual. Instruct them in the operation and maintenance requirements of the unit. Make sure they know who to call for service. 14. Fill out the Customer Evaluation and Warranty Registration form, and mail it in to Scotsman or register the unit at Scotsman's website (www. scotsman-ice.com). 1. Remove upper front panel 2. Open the water hand valve, observe that water enters the water reservoir, fills and then shuts off. Check for leaks. Repair any leaks before going any further. 3. Switch electrical supply on. Lights on controller will flash and then the power light will remain on. The code display will show O. January 2025 Page 10 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Operation: Ice and Water Vending Dispensing takes place when the Touch Free sensor's infrared beam bounces back to the sensor from a container placed directly in front of it. If the container is in front of the Touch Free sensor on the left side, the ice dispensing rotor will rotate and sweep ice over the ice dispensing chute. Ice will continue to discharge out this chute as long as the rotor is turning. It stops when the rotor stops. · Both dispensing and ice making are disabled when the unit is switched off at the controller. Splash panel wipe-off. Wiping the splash panel could result in unintended dispensing. To avoid that, a disable button has been provided. It is recessed into the bottom of the chute panel. Push and release it to disable dispensing for 60 seconds. Vending Disable Switch Dispense Sensors Noise If the user does not remove the container, The machine will stop dispensing ice after 24 seconds.. This is a commercial ice machine. It contains a powerful compressor, heavy duty gear reducer and, if air cooled, a fan that moves a lot of air. It will produce some noise when it is making ice. Every effort was made during its design to minimize the sound level but some noise during operation is unavoidable. If the container is in front of the Touch Free sensor on the right side, the inlet water valve will open and water will flow into the container. If the user does not remove the container, the machine will stop making ice after 20 seconds. Note: Water may dispense cloudy and then clear up in the glass. That is normal due to air in the water and is not an indicator of any malfunction. Other notes: · An occasional drip may be seen from the ice dispense chute. This is normal and is from ice melting inside the chute. A continuous stream of water from the ice chute indicates a restricted bin drain. · Clear containers (glass or plastic) may not always activate the dispense sensors. Reposition your hand to active the sensor in these situations. January 2025 Page 11 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Controller All models use the same control system. The electronic controller operates the compressor (with fan motor), auger drive motor, dispense drive motor and inlet water solenoid valve. It monitors: · Reservoir water availability · Storage bin ice level · Call for ice dispense · Call for water dispense · Refrigeration pressure · Dispense enable / disable · Auger motor speed · Auger motor rotation · Any installed control options Many of these are used to ensure that the machine does not damage itself during use. For example, it is critical that it not attempt to make ice without water. So if the water sensor is dry, the machine will not make ice. Switches - there are four switches: · Dispense water - To test water dispensing · Dispense ice - To test ice dispensing · ON/OFF - To switch the machine on or off. Holding it in to shut off will stop ice making immediately. · Clean - To engage the clean mode Indicators - there are nine LEDs: · Power - Glows when controller has power · Status - Glows when in ice making mode · Time to Clean - Glows when it is time to clean the machine · Water Dispense Sensed - Glows when the water dispense sensor has been triggered* · Ice Dispensed Sensed - Glows when the ice dispense sensor has been triggered* · Water Dispense - Glows when the inlet water solenoid valve has been powered* · Ice Dispense - Glows when the ice dispense motor has been powered* · Auger - Glows when the auger motor is on · Compressor - Glows when the compressor is on There is also a code display, the codes are: O - - - off F - - - ice making b - - - bin full E - - - controller error C - - - clean mode d - - - test mode 1 - - - auger rotation direction wrong 2 - - - auger speed too slow 3 - - - no water sensed 4 - - - high refrigerant pressure If a number code is triggered, the controller will stop ice making. A blinking code means it is a temporary condition. Example: A blinking F occurs during the ice making restart process; it stops blinking when the compressor starts. The controller will automatically restart from a water interruption or power interruption or when a refrigerant pressure switch has automatically reset. To reset the control when it has been manually locked out, push and release the ON/OFF button to shut it off and then push and release it again to switch it on. Note: The compressor will not restart for 2 minutes from the time it was shut off. * If blinking, the water or ice dispensing time limit has been met. January 2025 Page 12 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Maintenance and Cleaning There are five areas of maintenance: Condenser. 1. Drain system 2. Air cooled condenser filter and condenser 3. Ice dispense bin and rotor 4. Photo eye ice level control The condenser fins may need cleaning too. Remove the left side air grill and brush any lint and dirt off the surface of the condenser. Vacuum any remaining dirt. Do not damage the fins of the condenser during cleaning. 5. Ice making water system Drain System 1. Remove upper front panel. 2. Twist dispense chutes clockwise and pull down to remove. 3. Push in dispense disable switch, remove screws holding lower front panel to unit and unplug lower panel sensors at the harness connection. Set panels aside. 4. Shut the machine off. 5. Pour hot water into the drain basin to confirm free drainage. 6. Clean the dispense chutes. Use ice machine scale remover if needed to dissolve scale. 7. Reverse to reassemble. Insert chutes and rotate CCW until they snap into place and stop. Air filter The air filter on the left side of the cabinet will capture significant dust and lint during operation. As the dirt builds up it begins to restrict air flow and causes the refrigeration system to work longer to make ice. Clean the air filter regularly. To remove, pull it forward from the louvers. Do not leave it out for extended periods of time. To clean, wash it at a utility sink. Return it to the unit when clean. January 2025 Page 13 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Maintenance and Cleaning - Dispensing bin and ice level controls The ice storage bin and rotor must be cleaned and sanitized on a regular basis (at least as often as the ice making system is cleaned). Hand tools and hand protection like rubber gloves are recommended for this procedure. 11. Mix a solution of ice machine scale remover, such as Scotsman Clear 1 and potable water per the directions supplied with the scale remover. Note: Some steps overlap with the procedure on the next page. This procedure can be independent of the ice making system cleaning or can be part of it. 1. Remove upper front panel. 2. Remove top panel. Dispense Rotor 3. Shut machine off. 4. Vend or melt out all ice. Note: Only add 16 oz water to the bin at a time, as excess water will drain out the spout. Dispense Drive Pin 5.

It is also sealed from leaking by a water seal at the bottom. The bearings are permanently lubricated and need no maintenance. They can be visually checked for obvious wear or damage but there is no need to add lubrication. Auger motor bearings and the gear reducer are also permanently lubricated and need no maintenance. The bottom of the ice making system should be checked for water leaks. Water draining from the bottom is an indication of a water seal leak. Immediate repair is required when a water seal leak is discovered. Caution: Moving parts hazard. Do not touch the rotating shaft at any time. Bearing Rotating Shaft Do NOT Touch January 2025 Page 17 HID312AWX, HID525AWX and HID540AWX Installation and User's Manual Basic Troubleshooting See the separate HIDX service manual for more advanced troubleshooting information.
