problem occurs. At startup a 5 second delay occurs while the board conducts an internal timer check. A short beep occurs when the power switch is turned ON or OFF.

The green LED’s 1-4 represent the corresponding relays and energize and sequence 5 seconds from initial startup as follows:

The built in safeties shut down the unit and have alarms as follows:

1 beep every 3 sec. = High Evaporator Temperature >127 ° F.

Check for defrost problem (stuck HGV or relay), hot water entering unit, stuck headmaster, or shorted thermistor.

2 beeps every 3 sec. = Defrost Back Up Timer. Defrost >20 minutes. Orange LED marked 20 MIN energizes.

Check for open thermistor, HGV not opening, TXV leaking by, low charge, or inefficient compressor.

3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > 60 minutes. Yellow LED marked 60 MIN energizes.

Check for F/S stuck closed (up), WV leaking by, HGV leaking by, TXV not feeding prop- erly, low charge, or inefficient compressor.

To manually reset the above safeties, depress white alarm reset button with the power supply ON.

6 beeps every 3 sec. = Low Voltage. Voltage is 92 Vac or less.

7 beeps every 3 sec. = High Voltage. Control voltage > 147Vac ±5%. The red LED will de-energize if voltage protection operates.

The voltage safety automatically resets when voltage is corrected.

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, & 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation.

The application switch located between relay X3 & X4 must be set to match the original board application. Place this switch in the ALP position if there is no white wire supplied

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.
