After the 1 minute ± 5 second water supply cycle and the 2 minute ± 10 second defrost cycle, the unit should start the freeze cycle.

(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. After the first 5 minutes of the freeze cycle, disconnect the Float Switch leads from the Controller Board.

At this point, the unit should start the defrost cycle.

(iv)After Step (iii), de-energize the unit and confirm that the Defrost Timer is in the minimum position. Disconnect the resistor from the Controller Board, and energize the unit.

After the 1 minute water supply cycle, the defrost cycle starts.

Re-connect a 1.5 k- 3.5 kresistor to the Connector K3 (pins #1 and #2) after the first 2 minutes of the defrost cycle.

The unit should start the freeze cycle after 1 minute ± 5 seconds from the resistor connection.

3) Check the Controller Board by using test program of the Controller Board.

The Output Test Switch “S3” provides a relay sequence test. With power OFF, place S3 ON and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, and 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation.

KM-2000SWH3, KM-2000SRF3, KM-2000SRH3, KM2000SWF3 specifications

The Hoshizaki KM-2000SRH3 and KM-2000SWH3 are two of the latest innovations in the world of ice-making machines, designed for high-demand commercial settings where reliability and efficiency are key. Known for their durability and performance, these machines are ideal for restaurants, bars, hotels, and other businesses that require a steady supply of ice.

One of the standout features of the KM-2000 series is its production capability. Both models are designed to produce a staggering amount of ice—approximately 2,000 pounds per day. This high output ensures that establishments are never left wanting, meeting the needs of peak service hours without interruption.

Hoshizaki has integrated advanced technologies into these machines to enhance efficiency and reduce downtime. The KM-2000SRH3 and KM-2000SWH3 come equipped with a reliable, self-contained refrigerant system that operates efficiently even in warmer environments. This is particularly important for businesses located in hotter climates, as it ensures that ice production remains consistent throughout the year.

Another notable technology included in both models is the unique crescent-shaped ice that they produce. This type of ice is not only aesthetically pleasing but also offers several functional advantages. The crescent shape allows for excellent cooling properties, making it perfect for drinks, while its hardness and density facilitate longer melting times, ensuring that beverages stay chilled for longer periods.

Additionally, Hoshizaki has incorporated a cleaning and sanitizing system in the KM-2000 series, ensuring that the ice produced is safe and hygienic. This built-in feature is crucial for maintaining health and safety standards in food service operations, reducing the need for manual cleaning and increasing operational efficiency.

In terms of design, both the KM-2000SRH3 and KM-2000SWH3 boast a compact footprint, making them suitable for spaces where size is a constraint. Their stainless steel construction not only adds to their durability but also enhances their visual appeal, fitting seamlessly into any commercial kitchen or bar environment.

Overall, the Hoshizaki KM-2000SRH3 and KM-2000SWH3 ice machines represent a convergence of efficiency, technology, and user-friendly design, making them a top choice for businesses that rely heavily on ice as a part of their service offerings. With their high production capabilities, advanced features, and commitment to quality, these models deliver reliable performance that operators can depend on day in and day out.
