b)Harvest Timer (S4 dip switch 1 & 2)

The harvest timer starts when the thermistor reads 48°F (9°C) at the evaporator outlet and the control board reads the thermistor's 3.9 kΩ signal. The harvest timer is factory set, and generally no adjustment is required. However, a setting longer than the factory setting may be advised in cases where the flush provided at harvest needs to be prolonged for extra cleaning. Before changing this setting, contact Hoshizaki Technical Support at 1‑800‑233‑1940 for recommendations. Keep in mind that setting the harvest timer to a longer setting decreases 24-hour production.

Note that the pump-out timer (S4 dip switch 3 & 4) acts in place of the harvest timer during cycles with a pump-out. For details, see "II.C.3.c) Pump-Out Timer (S4 dip switch

c) Pump-Out Timer (S4 dip switch 3 & 4)

CAUTION

Do not adjust S4 dip switch 3 off and S4 dip switch 4 on for KM-1601SAH/3. Otherwise, pump motor does not rotate in the pump-out direction.

When a pump-out is called for, the pump motor stops after the preceding freeze cycle. The pump motor restarts 2 seconds later in the reverse direction, taking water from the bottom of the water tank and forcing pressure against the pump-out check valve seat allowing water to go through the pump-out check valve and down the drain. At the same time, water flows through the small tube to power flush the float switch. The pump motor drains the water tank for the time determined by the pump‑out timer. The pump‑out timer also acts in place of the harvest timer during cycles with a pump-out. The pump-out timer is factory set, and generally no adjustment is required. The pump-out timer control can be set to pump-out for 10 or 20 seconds.

KM-1601SWH/3, KM-1601SRH/3, KM-1601SAH/3 specifications

Hoshizaki has long been a trusted name in the world of commercial refrigeration and ice-making equipment. Among its offerings, the KM-1601SAH/3, KM-1601SRH/3, and KM-1601SWH/3 models stand out for their innovative features and robust design. These machines are integral for businesses that require reliable and efficient ice production, such as restaurants, hotels, and convenience stores.

At the core of these models is Hoshizaki's renowned Crescent Cube Technology, which produces clear, crescent-shaped ice that is ideal for both beverage service and food presentation. The unique shape of the ice ensures reduced melting rates, helping to maintain beverage temperature for longer periods while minimizing dilution. Additionally, the crescent ice is less prone to clumping, making it easier to dispense and ideal for high-volume use.

One of the key features of the KM-1601 series is its exceptional ice production capacity. Each model can produce up to 1,600 pounds of ice in a 24-hour cycle, making them suitable for heavy-demand environments. The machines are constructed with a durable stainless steel exterior, providing not only a sleek look but also enhanced resistance to corrosion and easy maintenance.

The KM-1601SAH/3 is designed with a built-in ice storage bin, allowing for seamless integration into various setups. Its state-of-the-art refrigeration system ensures optimal energy efficiency, which is crucial for businesses looking to manage operational costs. The KM-1601SRH/3 includes a self-contained design, simplifying installation and reducing the need for external ice storage solutions.

For users concerned with hygiene, these models boast advanced sanitation features. Hoshizaki's Antimicrobial Agent is incorporated into key components to inhibit the growth of bacteria and slime, ensuring cleaner ice production. The machines also feature easy-to-access panels for quick cleaning and maintenance, reducing downtime.

Another significant characteristic is their user-friendly controls, which simplify operation and monitoring of ice production. The built-in monitoring system alerts users to any potential issues, allowing for proactive maintenance and minimal disruption to service.

The KM-1601SWH/3 model further enhances the lineup with its energy-efficient design, lightweight construction, and compact footprint, making it perfect for establishments with limited space. Collectively, these models reflect Hoshizaki's commitment to innovation, efficiency, and reliability in ice-making technology, making them a top choice for businesses that require substantial ice production without compromising on quality or safety. Whether you need a powerful ice machine for a bar, restaurant, or convenience store, Hoshizaki’s KM-1601 series delivers performance that you can depend on.
