3.REMOVAL AND REPLACEMENT OF COMPRESSOR IMPORTANT

Always install a new Drier every time the sealed refrigeration system is opened. Do not replace the Drier until after all other repair or replacement has been made.

Note: When replacing a Compressor with a defective winding, be sure to install the new Start Capacitor and Start Relay supplied with the replacement Compressor. Due to the ability of the POE oil in the compressor to absorb moisture quickly, the Compressor must not be opened more than 15 minutes for replacement or service. Do not mix lubricants of different compressors even if both are charged with R-404A, except when they use the same lubricant.

1)Turn off the power supply.

2)Remove the panels.

3)Recover the refrigerant and store it in an approved container.

4)Remove the Terminal Cover on the Compressor, and disconnect the Compressor Wiring.

5)Remove the Discharge and Suction Pipes using brazing equipment.

6)Remove the Hold-down Bolts, Washers and Rubber Grommets.

7)Slide and remove the Compressor. Unpack the new Compressor package. Install the new Compressor.

8)Attach the Rubber Grommets of the prior Compressor.

9)Sandpaper the Suction, Discharge and Process Pipes.

10)Place the Compressor in position, and secure it using the Bolts and Washers.

11)Remove plugs from the Suction, Discharge and Process Pipes.

12)Braze the Process, Suction and Discharge lines (Do not change this order), while purging with nitrogen gas flowing at the pressure 3-4 PSIG.

13)Install the new Filter Drier.

14)Check for leaks using nitrogen gas (140 PSIG) and soap bubbles.

KM-2000SWH3, KM-2000SRF3, KM-2000SRH3, KM2000SWF3 specifications

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.
