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. If necessary, check for resistance between Thermistor leads, and visually check the Thermistor mounting, located on the Suction Line next to the Evaporator outlet.

Check a thermistor for resistance by using the following procedures.

(i)Disconnect the connector K3 on the board.

(ii)Remove the Thermistor. See “V. 11. REMOVAL AND REPLACEMENT OF THER- MISTOR.”

(iii)Immerse the Thermistor sensor portion in a glass containing ice and water for 2 or 3 minutes.

(iv)Check for a resistance between Thermistor leads.

Normal reading is within 3.5 to 7 k. Replace the Thermistor if it exceeds the normal reading.

2)Defrost Timer

No adjustment is required under normal use, as the Defrost Timer is adjusted to the suitable position. However, if necessary when all the ice formed on the Evaporator does not fall into the bin in the harvest cycle, adjust the Defrost Timer to longer setting by adjusting the Dip Switch (No. 1 & 2) on the Controller Board.

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.
