h)Freeze Termination Diagnosis: After 5 min. in freeze, disconnect CB K5 FS connector. 15 sec. later appliance should switch out of the freeze cycle (15 second delay after FS opens before terminating the freeze cycle). If appliance remains in freeze longer than 15 sec. after FS removed, replace CB. If appliance switches with FS removed but would previously not switch out of freeze with FS connected (long freeze - 3 beep alarm), see "II.E. Float Switch Check and Cleaning."

Note: Normal freeze cycle will last 20 to 40 min. depending on model and conditions. Cycle times and pressures should follow performance data provided in this manual. See "VIII.A. Specification and Performance Data."

i)Short Freeze Cycle Diagnosis: Confirm water tank fills and overflows during 1 min. fill and harvest cycles. If not, check water supply filters, shut-off valve, WV screen. If water tank empties before 5 min. timer terminates and freeze cycle is short, check that CV is not leaking by (water flowing down the potable drain). If CV is leaking by, remove and clean CV, replace rubber seat and spring if necessary. If water tank is full, see "II.E. Float Switch Check and Cleaning" for erratic operating FS.

7)Pump-Out Cycle – LEDs 1, 3, and 2 are on (10/20 second pump-out).Timing of the first pump-out is dependent on CB. "E" CB first pumpout is after the first freeze cycle. "G" CB first pump-out is determined by S4 dip switch 5 & 6. See the table below.

Comp and FMR continue, HGV energizes. If S4 dip switch 3 & 4 are set to 3 off and

4 on, LED 4 turns on and WV energizes. FM and LLV deenergize. PM stops for 2 sec., then reverses for 10/20 sec. depending on pumpout timer (S4 dip switch 3 & 4) setting. When the pumpout timer terminates, pumpout is complete. The pump-out frequency control (S4 dip switch 5 & 6) is factory set, and generally no adjustment is required. However, the pumpout frequency control can be set to have a pumpout occur every cycle, or every 2, 5, or 10 cycles. For details, see "III.C.4. PumpOut Frequency Control (S4 dip switch 5 & 6)."

Pump-Out Diagnosis: In the freeze cycle before pump-out (see table above), disconnect CB black K5 connector (FS connector) after 5 min. of freeze. Check that PM stops and re-starts and water is flowing down the drain through CV. If PM does not stop and re-start, check that CB LEDs 1, 3, and 2 are on. If not, replace CB. If LEDs 1, 3, and 2 are on and PM does not energize, check for 115VAC at CB K1 #5 (DBU) to neutral (W). If 115VAC is not present, replace CB. If 115VAC is present, make sure the drain line is not clogged and that CV is clean and operating properly.

Confirm FM and LLV de-energize. If FM or LLV is energized with LEDs 1, 3, and 2 on, replace CB.

SRH/3 KM-1900SAH/3, SRH3 KM-2500SWH3, SRH3 KMH-2000SWH/3, SWH/3, KM-1301SAH/3 specifications

The Hoshizaki KM-1301SRH/3, KM-1301SWH/3, and KM-1301SAH/3 are advanced ice makers designed for commercial use, addressing a wide variety of needs in restaurants, hotels, and bars. These models are known for their efficiency, durability, and innovative technologies that ensure the production of high-quality ice.

One of the standout features of these units is their ability to produce a high volume of ice, reaching up to 1,300 pounds per day, which is crucial for establishments with heavy ice demands. The machines utilize advanced cooling technology, allowing for faster ice production and minimizing the time required to refill ice bins. This makes them ideal for busy settings where speed and efficiency are paramount.

The KM-1301 series employs a unique stainless steel exterior that not only ensures longevity and resistance to corrosion but also enhances the aesthetic appeal of any commercial kitchen or bar. The interior is designed for easy cleaning, helping to maintain hygiene standards vital for food safety.

These ice makers utilize the proprietary Hoshizaki Cubelet Ice system, producing small, chewy ice cubes that are perfect for various beverages and food displays. The advanced design of the ice-making mechanism ensures that ice is formed quickly and efficiently, reducing energy consumption. Additionally, Hoshizaki’s CycleSaver technology optimizes the production process by reducing the amount of water used, making these machines environmentally friendly.

Another characteristic is their self-diagnostic capability, which allows for real-time monitoring of unit performance and quicker troubleshooting, minimizing downtime. The built-in alerts notify operators of any issues or maintenance needs, ensuring that the ice-making process remains uninterrupted.

The KM-1301 series also provides user-friendly controls that allow easy adjustments and monitoring of ice production settings. This flexibility enables businesses to meet varying ice demands based on seasonality or special events.

In summary, the Hoshizaki KM-1301SRH/3, KM-1301SWH/3, and KM-1301SAH/3 ice makers are exemplary choices for commercial ice production. With their high output, durable design, energy efficiency, innovative technologies, and user-friendly features, they cater effectively to the rigorous demands of the foodservice industry while maintaining a commitment to quality and sustainability.
