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.

3)All models are pretested and factory-adjusted.

[b] Controller Board

CAUTION

1.Fragile, handle very carefully.

2.A controller board contains integrated circuits, which are susceptible to failure due to static discharge. It is especially important to touch the metal part of the unit when handling or replacing the board.

3.Do not touch the electronic devices on the board or the back of the board to prevent damage to the board.

4.Do not change wiring and connections. Do not misconnect K3, K4 and K5, because the same connector is used for the thermistor and float switch. K4 is not connected.

5.Always replace the whole board assembly when it goes bad.

6.Do not short out power supply to test for voltage.

Features of Control Products “E” Controller Board

(1)Maximum Water Supply Period - 6 minutes

Water solenoid valve opening in the defrost (harvest) cycle is limited by the defrost timer. The water valve cannot remain open longer than the maximum period. The water valve can close in less than six minutes if the defrost cycle is completed.

(2)Defrost Timer

The defrost cycle starts when the float switch opens and completes the freeze cycle. But the defrost timer does not start counting until the thermistor senses 48°F at the evaporator outlet. The period from the end of the freeze cycle up to the point of the thermistor's sensing varies depending on the ambient and water temperatures.

KM-1300SRH3, KM-1300SWH, KM-1300SRH, KM-1300SAH, KM-1300SWH3 specifications

The Hoshizaki KM-1300 series ice makers are designed to meet the demands of high-volume establishments requiring consistent, high-quality ice production. Among the models in this series are the KM-1300SAH3, KM-1300SWH, KM-1300SRH3, KM-1300SWH3, and KM-1300SAH, each boasting a variety of features and technologies to enhance efficiency and reliability.

One of the standout features of the KM-1300 series is its impressive ice production capacity. Each model is capable of producing up to 1,300 pounds of ice in a 24-hour period, making them ideal for busy restaurants, hotels, or bars that serve a high volume of customers. The machines are designed to create crescent ice, known for its pellet-like texture that is perfect for drink service and food display.

Energy efficiency is another key characteristic of the Hoshizaki KM-1300 models. They are equipped with a highly efficient refrigeration system that minimizes energy consumption while maximizing output. Many of the models in this series are certified by Energy Star, helping operators reduce their environmental footprint and lower operational costs.

Durability and ease of maintenance are also prominent features of the KM-1300 series. Constructed with stainless steel exteriors, these ice makers are built to withstand the rigors of a busy kitchen environment. Additionally, Hoshizaki has incorporated a unique air-cooled condenser design, which reduces the need for frequent servicing and minimizes downtime.

The KM-1300SAH3 and KM-1300SAH models come with advanced touch controls and a user-friendly interface, allowing operators to monitor and adjust settings with ease. The built-in self-diagnostic system alerts users to potential issues before they escalate, improving reliability and ensuring consistent ice production.

For those seeking flexibility, the KM-1300 series also offers modular designs, enabling operators to stack units or configure them in various layouts to optimize space. This adaptability makes these ice makers a smart choice for establishments with limited room or specific design requirements.

In summary, the Hoshizaki KM-1300 series ice makers combine efficiency, durability, and high production rates with advanced technology and user-friendly features. Ideal for high-demand environments, these machines deliver reliable performance and consistent ice quality, making them a valuable asset for any food service operation.
