HID312, HID525 and HID540 Installation and User’s Manual Placement The location of the equipment should be selected with care. Consideration should be given to allow adequate space on the sides for air cooled models to breathe. Minimum clearances for air cooled models: Cafeteria applications. The unit can be placed in a cafeteria line for ice and water. As some users sometimes dispense too much ice, high volume use may require the drip tray to be occasionally cleared of spilled ice.
HID312, HID525 and HID540 Installation and User’s Manual Counter Installations Units placed on a counter must either use legs or be sealed to the counter top with food grade sealant per local codes. To avoid disturbing the seal, complete the installation prior to sealing. Panel Removal Remove one screw at bottom front of upper front panel, swing bottom of panel forward and lift off the unit. Note: Seal Chassis to Counter, do NOT Seal Drip Tray Legs 4” legs are optional for countertop applications.

HID312, HID525 and HID540 Installation and User’s Manual Installation 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.
HID312, HID525 and HID540 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.
HID312, HID525 and HID540 Installation and User’s Manual Operation: Ice and Water Vending During ice making soft ice is compressed thru a die and then broken off into irregular lengths. It will not be clear and, because of melting, when dispensed it will not be uniform in size or shape. 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.
HID312, HID525 and HID540 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.
HID312, HID525 and HID540 Installation and User’s Manual Maintenance and Cleaning There are five areas of maintenance: 4. Remove screws holding lower front panel to unit and unplug lower panel sensors at the harness connection. Set panels aside. 1. Drip tray and drain system 2. Air cooled condenser filter and condenser Dispense Sensor Harness Disconnect 3. Ice dispense bin and rotor 4. Photo eye ice level control 5. Ice making water system Drip Tray It is important to keep the drip tray clean of trash.
HID312, HID525 and HID540 Installation and User’s Manual 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. Remove Top Panel To clean, wash it at a utility sink. Return it to the unit when clean.
HID312, HID525 and HID540 Installation and User’s Manual Maintenance and Cleaning - Dispensing Bin Components The ice storage bin and rotor must be cleaned and sanitized on a regular basis, at a minimum when the ice making system is cleaned. Hand tools and hand protection like rubber gloves are recommended for this procedure. 10. Lift up and remove dispense rotor, set aside. Note: Some steps overlap with the procedure on the next page.
HID312, HID525 and HID540 Installation and User’s Manual Ice level controls Clean if the controller indicates bin full and there is no ice between the sensors. 1. Remove top front and top panels. 6. Remove the chute mounting panel. 2. Shut machine off. 3. Disconnect ice level controls at connector. 4. Remove 3 screws and ice storage bin cover. 5. Pull each sensor grommet clip up and off. Clip Cover 7. Remove splash panel, disconnect sensors from harness and set panel aside. Sensor Grommet 6.
HID312, HID525 and HID540 Installation and User’s Manual Ice Making and Ice Dispensing System Cleaning Instructions Hand tools, cleaning supplies and hand protection are recommended for this procedure. Frequency: Recommended minimum time between cleanings is 6 months. To aid in determining if the machine has not been cleaned in 6 months, a Time To Clean light will glow after 6 months of power up time. Cleaning the machine with the following process will reset that light and the timer that controls it.
HID312, HID525 and HID540 Installation and User’s Manual 14. Push the Clean button. The unit will operate the auger motor for 30 minutes and then stop. Note: Stop at any time by pushing the On/Off button. 15. Disconnect unit from electrical power. 16. Drain the scale remover solution from the water system by pulling the reservoir drain hose from its plug and return it to the plug when drained. 17. Pour 24 ounces of clean, potable water into the reservoir. 18.
HID312, HID525 and HID540 Installation and User’s Manual Other Maintenance The auger in the ice making system is centered by bearings at the top and bottom. It is also sealed from leaking by a water seal at the bottom. The bearings are permanently lubricated and need no maintenance. The can be visually checked for obvious wear or damage but there is no need to add lubrication. Bearing Auger motor bearings and the gear reducer are also permanently lubricated and need no maintenance.
