Water The quality of the water supplied to the ice machine will have an impact on the time between cleanings and ultimately on the life of the product. There are two ways water can contain impurities: in suspension or in solution. Suspended solids can be filtered out. In solution or dissolved solids cannot be filtered, they must be diluted or treated. Water filters are recommended to remove suspended solids. Some filters have treatment in them for suspended solids.
General Installation - Air or Water Cooled Location Limitations: The product is designed to be installed indoors, in a controlled environment. Air cooled models discharge very warm air into the room out the back. Space must be allowed at the left side and back for air intake and discharge. Water cooled models discharge warm water into the building’s drain. Space needs to be provided on both sides and above for service access.
General Installation - Air or Water Cooled Plumbing Requirements All models require connection to cold, potable water. A hand actuated valve within site of the machine is required. Air cooled models have a single 3/8” FPT inlet water connection; a 3/8” FPT to 3/8” male flare adapter is supplied with the machine and can be used if desired. Water cooled models have the same inlet fitting plus an additional 3/8” FPT condenser inlet water connection.
General Installation - Air or Water Cooled Electrical See the spec sheet or User's Manual for Minimum Circuit Ampacity or Maximum Fuse Size ratings. The machine is not supplied with a power cord, one must either be field installed or the machine hard-wired. The dataplate on the back of the cabinet details the power requirements, including voltage, phase, minimum circuit ampacity and maximum fuse size. HACR type circuit breakers may be used in place of fuses. Extension cords are not permitted.

General Installation - Remote Remote Condenser Location Use the following for planning the placement of the condenser relative to the ice machine - see illustration on the following page. Location Limits - condenser location must not exceed ANY of the following limits: • • • • Maximum rise from the ice machine to the condenser is 35 physical feet Maximum drop from the ice machine to the condenser is 15 physical feet Physical line set maximum length is 100 feet. Calculated line set length maximum is 150.
General Installation - Remote For The Installer: Remote Condenser Locate the condenser as near as possible to the interior location of the ice machine. Note: The location of the condenser is relative to the ice machine is LIMITED by the specification on the prior page. Meet all applicable building codes.
General Installation - Remote Precharged Line Routing Do not connect the precharged tubing until all routing and forming of the tubing is complete. See the Coupling Instructions for final connections. 1. Each set of pre-charged tubing lines contains a 3/8” diameter liquid line, and a 1/2” diameter discharge line. Both ends of each line have quick connect couplings, the end without access valves goes to the ice maker.
General Installation - Remote Coupling Instructions The couplings on the ends of the pre-charged line sets are self-sealing when installed properly. Follow these instructions carefully. These steps must be performed by an EPA Certified Type II or higher technician. Initial Connections 1. Remove the protector caps and plugs. Wipe the seats and threaded surfaces with a clean cloth to remove any possible foreign matter. 2. Lubricate the inside of the couplings, especially the O-rings, with refrigerant oil. 3.
Pre-Charged Tubing Coupling Connections Inspect couplings, wipe clean and lubricate both parts with polyolester refrigerant oil. Hand tighten to be sure threads are properly engaged. Use two wrenches and continue tightening the couplings. As the diaphragms being to pierce, the couplings will be harder to turn. Be sure only the swivel nut is rotated. Continue tightening until the swivel nut feels like it is tight, then go to the next step. No threads will be seen when the couplings are tight.
General Installation - Remote Plumbing Requirements All models require connection to cold, potable water. A hand actuated valve within site of the machine is required. There is a single 3/8” FPT inlet water connection, a 3/8” FPT to 3/8” male flare adapter is supplied with the machine and can be used if desired. Water Filters Install a new cartridge if the filters were used with a prior machine. All models require drain tubing to be attached to them.

How It Works - Air Cooled Freeze Cycle. At start up the controller drains and refills the reservoir. The reservoir refills when the mid length water level sensor probe is uncovered and continues to fill until the top probe is in contact with water. When the reservoir has filled, the compressor and water pump start. After the discharge pressure has increased past the cut in point of the fan pressure control, the fan motor(s) will begin to operate and warm air will be discharged out the back of the cabinet.

Electrical Sequence - Remote Cooled The harvest assist solenoid is connected in parallel with the hot gas valve. Although it is energized throughout the harvest cycle, its piston does not move until the ice has become partially loosened from the evaporator plate by the action of the hot refrigerant gas passing through the evaporator serpentine. The remote condenser fan motor is powered by the compressor contactor, so it will be operating during the harvest cycle.

Test Procedures - Sensors All electrical components in this ice machine can be diagnosed with a volt-ohmmeter. Curtain Switch: 1. Test using the controller’s indicator lights. Observe SW1 and SW2. Open and close the curtain in question. When the curtain is opened, the SW light will be ON. When the curtain gets to within a half inch of closing (at the switch) the SW light will go OUT. 2. Test with an ohmmeter. Disconnect electrical power. Open the control box cover.
Ice Thickness Sensor 1. Test using the controller’s indicator light. Observe the Ready To Harvest light. Shut the machine off. Use a wire to connect the metal part of the Ice Thickness sensor to the evaporator or simply remove the Ice Thickness Sensor and touch its metal surface to the metal control box wall. The Ready for Harvest light should go ON. 2. Test with an Ohmmeter. Disconnect electrical power. Open the control box cover. Unplug the ice thickness sensor lead from the controller.
Water Level Sensor 1. Test using the controller’s indicator lights (sump empty and sump full). Unit must be powered up and there must be water in the sump. Add some manually if needed. Locate water level sensor. Release from sump cover and slowly lift up until the mid-length probe is out of the water. The sump empty light should come on, and if the unit is on the inlet water solenoid valve will open to fill the reservoir. Return the water level sensor to its normal position.
Temperature Sensors 1. Check controller. If the sensor calibration is completely out of range, the code display will read either 5 or 7. 2. Check with an ohmmeter. Open control box cover, unplug sensor from J6. Water temperature probe: Measure the temperature of the water. Push and release the clean button. Wait one minute. Measure the resistance of the water probe (two leads next to the open socket) and compare to the resistance in the chart for that temperature. Any reading within 1000 ohms is acceptable.
Test Procedures - Loads Compressor Failure to start. Single phase models. All have resistance start, capacitor run type motors. Check voltage to compressor at the contactor. Compare the idle voltage (compressor off) to the active voltage (compressor starting). The supply voltage must not be less than the lowest rated voltage for the ice machine. If the voltage is correct, proceed to the next step. Check starting components.

Test Procedures - Loads Purge valve 1. Test using the controller’s indicator lights. Shut unit off by holding the Off button for 3 seconds. Wait four minutes. Push and release the On button, observe the Purge Valve indicator light. As the unit drains the reservoir, the purge valve will be powered. When it gets power, the indicator light will be ON. If the purge valve does not open to drain the reservoir when its indicator light is on, do a voltage check.
Test Procedures - Loads Compressor contactor 1. Test using the controller’s indicator lights. When the unit is in ice making mode the compressor contactor will have power. Check the Compressor indicator light, when it is on the compressor contactor will have pulled in. If it is not, do a voltage check. Place voltmeter leads on the coil of the contactor. There should be full voltage . If there is full voltage present and the contactor has not pulled in, replace the contactor.
Test Procedures - Loads Pressure switches There are two pressure switches: Fan and High Pressure cut out. Fan. The fan pressure switch will open to shut the fan motor off at a certain pressure and re-close at a preset higher pressure. High pressure cut out. The high pressure cut out switch will open at a preset pressure, shutting off power to the compressor contactor. After the pressure has fallen to another preset level, the switch will re-close and the contactor coil will be engergized.
Test Procedures - Loads Liquid Line Solenoid (remote only) 1. Test using the controller’s indicator lights. Put the controller into test mode (depress Off for 3 seconds then depress Clean for 3 seconds). At the end of the test cycle, the liquid line valve will be powered and the Condenser Fan motor indicator light will be on. The liquid line valve should be open at that time.
Test Procedures - Loads Inlet Water Solenoid Valve 1. Test using the controller’s indicator lights. Shut unit off by holding the Off button for 3 seconds. Wait four minutes. Push and release the On button, observe the Water Solenoid indicator light. After the unit drains the reservoir, the inlet water valve will be powered to refill the reservoir. When it gets power, the indicator light will be ON. If the water valve does not open to fill the reservoir when its indicator light is on, do a voltage check.
Test Procedures - Loads Harvest assist solenoid 1. Test using the controller’s indicator lights. Push and release the Harvest button. The Hot Gas indicator light will be on.

Optional add-on control information Vari-Smart™ Adjustable ice level option The adjustable ice level control is an optional add-on system consisting of an control board, label and sensor. The control board fits above the standard control and connects to it using connector J4. The sensor mounts to the base of the ice machine through a hole in the base. The control has an adjustment knob. Rotating the knob CW lowers the maximum ice level that the ice machine will maintain in the bin or dispenser.
Adjustable Ice Level System Information and Diagnosis The ultrasonic sensor in the base of the ice machine is located to take advantage of the natural slope of the ice as it builds up in the bin. The numbers of the settings are from the sensor to the top of the ice pile directly under the sensor. If the Vari-Smart system fails to shut off the machine and ice overfills the bin or dispenser, the curtain switch in the machine will switch the machine off, and will also restart the machine when ice is removed.
Prodigy's Smart-Board™ - an Advanced Feature Control An optional control is available that can provide users with more features. It is available either as a field installed option or as a data-logger that can be used by the service technician. The kit number for the add on option is: KSBU The kit number for the data logger version is: TPDL1 or TPDL2 The Smart-Board can be applied to most Prodigy models.

Remote SmartLock (KSL) The remote lock out feature can be added to any controller. The feature allows someone, using a special paging service and code to control the on and off operation of that ice machine. When a controller is locked out, the machine will finish a cycle and then stop. Switching the power off and on, pushing any amount or combination of switches will not restart the machine. It can only restart when it receives a clear signal from the remote lockout board.
