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.

•Precharged factory line sets, available as optional equipment from Hoshizaki America, are recommended. For details, see "II.G.4.a) Factory Line Set Installation." Field fabricated line sets are allowed. For details, see "II.G.4.b) Field Fabricated Line Set Installation."

•The maximum line length for the standard refrigerant charge is 66 feet. With additional refrigerant, the maximum line length is 100 feet. For details, see "II.G.5. Refrigerant Charge (Line Set Exceeding 66 Feet)."

a)Factory Line Set Installation

1)Route the factory line set (5/8" OD discharge line and 3/8" OD liquid line) from the remote condenser unit to the icemaker. Leave a service loop behind the icemaker to allow the icemaker to be pulled out for service. See Fig. 12. Factory fabricated line sets are precharged and do not need to be evacuated. If the line set is too long or too short, see "II.G.4.a)(1) Factory Line Set Modification."

Note: The service loop is not considered an oil trap.

CAUTION

1.Ensure that there are no traps and no kinks in the line set.

2.Do not coil extra line set.

2)Connect the refrigerant lines to the appropriate male fittings on the remote condenser unit first and then at the icemaker. Make a proper connection as follows:

a.Remove the protective covers from the male fitting and female coupling.

b.Apply Polyol Ester (POE) refrigerant oil or Parker Super O Lube to the entire male fitting, including O‑ring, diaphragm, and threads before making the connection. See Fig. 13.

CAUTION

Do not use thread sealant on the fittings. Use POE refrigerant oil or Parker Super O Lube only.

c. Make sure the male fitting and female coupling are properly aligned, then start the connection by hand to ensure that it is not cross threaded.

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. The KM-1900SRH/3 specializes in producing nugget ice, a favorite among beverage enthusiasts.

In summary, the Hoshizaki KM-1900 series stands out for its robust performance, innovative features, energy efficiency, and user-friendly design, making it an ideal choice for any commercial ice-making application.
