16 2. Controller Board [a] Solid-State Control 1) A HOSHIZAKI exclusive solid-state control is employed in KM-1300SAH, KM-1300SWH, KM-1300SRH, KM-1300SAH3, KM-1300SWH3, and KM-1300SRH3 Stackable Crescent Cubers. 2) A printed circuit board (hereafter called “controller board”) includes a stable and high quality control system.
17 (3) High Temperature Safety - 127 ± 7°F The temperature of the suction line in the refrigerant circuit is limited by the high temperature safety. During the defrost cycle the evaporator temperature rises. The thermistor senses 48°F and starts the defrost timer.
18 The green LED’s 1-4 represent the corresponding relays and energize and sequence 5 seconds from initial startup as follows: Sequence Step LED’s on Length: Min. Max. Avg. 1 Minute Fill Cycle LED4 60 sec. Harvest Cycle LED1, 4, & 2 2 min. 20 min.
19 The dip switches should be adjusted per the adjustment chart published in the Tech Specs book. 7 & 8 must remain in the OFF position. (Control Products HOS-001A Board).
20 4. Defrost Timer stops counting. Defrost cycle is completed and freeze cycle starts. [c] Sequence 1st Cycle 1. Unit energized and Control Switch to “ICE” position. Water supply cycle starts. 2. After 1 minute. Defrost cycle starts. IMPORTANT Water Valve opening is limited to 6 minutes.
21 2nd Cycle and after with pump drain IMPORTANT Freeze cycle time is limited by the freeze timer factory setting even if the Float Switch does not open. 1. Float Switch opens and signals to complete freeze cycle. Drain timer starts counting. 2. Drain timer stops counting.
22 2nd Cycle and after with no pump drain IMPORTANT Freeze cycle time is limited by the freeze timer factory setting even if the Float Switch does not open. 1. Float Switch opens and signals to complete freeze cycle. 2. Thermistor reads 48° F. Defrost Timer starts counting.
23 [d] Controls and Adjustments The dip switch is factory-adjusted to the following positions: Switch Nos. 1 and 2: Used for adjustment of the defrost timer. The defrost timer starts counting when the thermistor reads a certain temperature at the evaporator outlet.
24 1) Defrost Control A thermistor (semiconductor) is used for a defrost control sensor. The resistance varies depending on the suction line temperatures. The thermistor detects the temperature of the evaporator outlet to start the defrost timer. No adjustment is required.
25 3) Drain Timer The drain timer is factory-adjusted and no adjustment is required. SETTING TIME Dip Switch Dip Switch No. 3 No. 4 T 1 T 2 OFF OFF 10 seconds 150 seconds ON OFF 10 seconds 180 seconds.
26 5) Freeze Timer CA UTION Adjust to proper specification, or the unit may not operate correctly. The freeze timer is factory adjusted and no adjustment is required. This setting determines the maximum allowed freeze time to prevent possible freeze-up issues.
27 (ii) After the above step (i), disconnect the float switch leads from the controller board within the first 5 minutes of the freeze cycle. The unit should go into the defrost cycle after the first 5 minutes ± 20 seconds of the freeze cycle. (iii) Reconnect the float switch connector to the controller board.

50 5) Disconnect the vacuum pump, and attach a refrigerant service cylinder to the high-side line. Remember to loosen the connection, and purge the air from the hose. For air-cooled and water- cooled models, see the nameplate for the required refrigerant charge.
51 3. Removal and Replacement of Compressor IMPORT ANT Always install a new drier every time the sealed refrigeration system is opened. Do not replace the drier until after all other repair or replacement has been made.
52 16) Connect the terminals, and replace the terminal cover in its correct position. 17) Replace the panels in their correct positions. 18) Turn on the power supply. 4. Removal and Replacement of Drier IMPORT ANT Always install a new drier every time the sealed refrigeration system is opened.
53 5. Remov al and Replacement of Expansion V alve IMPORT ANT Sometimes moisture in the refrigerant circuit exceeds the drier capacity and freezes up at the expansion valve. Always install a new drier every time the sealed refrigeration system is opened.
54 6. Remo val and Replacement of Hot Gas V alve and Line V alve CA UTION Always use a copper tube of the same diameter and length when replacing the hot gas lines; otherwise the performance may be reduced. IMPORT ANT Always install a new drier every time the sealed refrigeration system is opened.
55 7. Removal and Replacement of Evaporator IMPORT ANT Always install a new drier every time the sealed refrigeration system is opened. Do not replace the drier until after all other repair or replacement has been made. 1) Turn off the power supply. 2) Remove the panels and the top insulation over the evaporator.
56 8. Remov al and Replacement of W ater Regulating V alve - W ater-Cooled Model Only IMPOR T ANT Always install a new drier every time the sealed refrigeration system is opened. Do not replace the drier until after all other repair or replacement has been made.
57 9. Adjustment of W ater Regulating V alve - W ater-Cooled Model Onl y The water regulating valve (also called “ water regulator ” ) is factory-adjusted. No adjustment is required under normal use. Adjust the water regulator, if necessary, using the following procedures: 1) Attach a pressure gauge to the high-side line of the system.
58 10. Remov al and Replacement of Condensing Pressure Regulator (C.P .R.) - Remote Air-Cooled Model Only IMPORT ANT Always install a new drier every time the sealed refrigeration system is opened. Do not replace the drier until after all other repair or replacement has been made.
59 11. Remo v al and Replacement of Thermistor CA UTION 1. Fragile, handle very carefully. 2. Always use a recommended sealant (high thermal conductive type), Model KE4560RTV manufactured by Shinetsu Silicone, Part Code 60Y000-11, or Part Code 4A0683-01 equivalent.
60 12. Removal and Replacement of Fan Motor Note: When replacing a fan motor with defective winding, it is recommended that a new capacitor be installed. 1) Turn off the power supply. 2) Remove the panels. 3) Remove the junction box cover from the remote condenser unit (remote air-cooled model).
61 13. Remov al and Replacement of W ater V alve 1) Turn off the power supply. 2) Close the water supply line shut-off valve. 3) Remove the front panel. 4) Remove the valve outlet tubing by releasing the clamp. 5) Remove the bracket from the unit. 6) Remove the fitting nut and water valve.
62 7) Remove the closed end connectors from the pump motor leads. 8) Remove the two screws and the pump motor bracket. 9) Remove the pump housing and check the impeller. 10) If the impeller is defective, install a new impeller. 11) Install the new motor or new parts, and replace the removed parts in the reverse order of which they were removed.
63 1. Preparing the Icemaker for Long Storage W ARNING When shutting off the icemaker for an extended time, drain out all water from the water tank and remove the ice from the storage bin.
64 [2] Remove the water from the potable water supply line: 1) Remove the front panel. (Except water-cooled model) 2) Move the control switch on the control box to the “ OFF ” position. 3) Wait 3 minutes. 4) Close the potable water supply line shut-off valve and open the potable water supply line drain valve.
65 2. Cleaning and Sanitizing Procedures IMPOR T ANT Ensure all components, fasteners and thumbscrews are securely in place after any maintenance or cleaning is done to the equipment. W ARNING 1. HOSHIZAKI recommends cleaning this unit at least once a year.
66 [a] Cleaning Procedure 1) Dilute 27 fl. oz. of the recommended cleaner Hoshizaki “ Scale Away ” or “ LIME-A-WAY ” (Economics Laboratory, Inc.) with 5 gal. of water. 2) Remove all ice from the evaporator and the storage bin. Note: To remove cubes on the evaporator, turn off the power supply and turn it on after 3 minutes.
67 19) Turn on the power supply to fill the water tank with water. 20) Turn off the power supply after 3 minutes. 21) Remove the front panel, and fully open the cleaning valve. 22) Move the control switch to the “ WASH ” position. 23) Replace the front panel in its correct position.
68 [b] Sanitizing Procedure - Following Cleaning Procedure 1) Dilute a 5.25% sodium hypochlorite solution (chlorine bleach) with water (Add 2.5 fl. oz. of sanitizer to 5 gal. of water). 2) Remove the insulation panel, if it is in its normal position. 3) Pour the sanitizing solution into the water tank.
69 3. Maintenance IMPOR T ANT This icemaker must be maintained individually, referring to the instruction manual and labels provided with the icemaker. 1) Stainless Steel Exterior To prevent corrosion, wipe the exterior occasionally with a clean and soft cloth.
