5. Refrigerant Charge (Line Set Exceeding 66 Feet)

CAUTION

The icemaker, line set, and remote condenser unit must contain the same type of refrigerant. Mixing of refrigerants will result in improper operation and possible damage to the refrigeration system.

The maximum line length for the standard refrigerant charge is 66 feet. Should an installation require a longer line length, additional refrigerant must be added. Add 0.4 oz. of R-404A for each foot over 66 feet to a maximum of 100 feet. Hoshizaki Technical Support is available at 1‑800-233-1940 for recommendations.

After weighing in the additional charge, mark the unit’s nameplate to show the new correct total refrigerant charge.

6. Electrical Connection

WARNING

1.Electrical connection must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or severe damage to equipment.

2.THE REMOTE CONDENSER UNIT MUST BE GROUNDED. Install a proper ground wire from the icemaker to the remote condenser unit. Use wire of an appropriate gage and outdoor rating. Failure to properly ground the unit could result in death or serious injury.

3.Install line and neutral wires from the fan motor leads in the icemaker to the leads in the remote condenser unit junction box. Use wire of an appropriate gage and outdoor rating.

4.Do not connect the fan motor leads in the icemaker to incoming power source. Do not connect the fan motor leads in the icemaker together. Do not allow the leads to contact the junction box walls.

5.Do not connect the remote condenser unit to an external power source.

6.To reduce the risk of electric shock, make all remote condenser unit connections before connecting the icemaker power supply.

7.The icemaker should have power for a minimum of 4 hours prior to startup to prevent compressor damage.

•Usually an electrical permit and services of a licensed electrician are required.

•The opening for the power supply connection is 7/8" DIA to fit a 1/2" trade size conduit.

KM-1900SWH/3, KM-1900SAH/3, KM-1900SRH/3 specifications

The Hoshizaki KM-1900 series, comprising the KM-1900SAH/3, KM-1900SWH/3, and KM-1900SRH/3 models, is recognized in the commercial ice-making industry for its exceptional performance and reliability. These machines are engineered for high efficiency, ensuring that businesses can meet their ice needs without compromising on quality or output.

One of the standout features of the KM-1900 series is its impressive ice production capability. With a production capacity of up to 1900 pounds of ice per day, these machines are designed to cater to high-demand environments such as restaurants, bars, and hotels. The energy-efficient operation of the KM-1900 series not only helps businesses save on electricity costs but also contributes to environmental sustainability, an increasing concern in today’s world.

The machines incorporate a sophisticated air-cooled condenser that aids in maintaining optimal ice production even in warmer conditions. This feature ensures a consistent performance throughout the year, regardless of external temperature fluctuations. Additionally, the KM-1900 models are equipped with a self-cleaning cycle, which simplifies maintenance and extends the longevity of the equipment. This automatic cleaning function helps reduce mineral buildup, thereby guaranteeing the ice’s purity and clarity.

In terms of design, the KM-1900 series showcases a durable stainless-steel exterior, which is both aesthetically pleasing and resistant to corrosion. The sleek design allows for easy integration into any commercial setting. The removable front panels also contribute to easier access for maintenance and service, minimizing downtime.

A significant technological advancement featured in this series is the unique “Kold-Dry” technology, which enhances the freezing process and ensures that the ice produced is harder and lasts longer. This feature is especially beneficial for businesses that require ice to stay intact for extended periods, such as seafood markets or catering services.

Furthermore, the KM-1900SAH/3, KM-1900SWH/3, and KM-1900SRH/3 models come with various ice types. The KM-1900SAH/3 produces traditional cubed ice suitable for drinks, while the KM-1900SWH/3 offers flake ice ideal for perishables.
