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.

1)Turn off the power supply.

2)Remove the panels.

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

4)Remove the screw and the Solenoid.

5)Disconnect the Hot Gas Valve or Line Valve.

6)Install the new valve.

WARNING

Always protect the valve body by using a damp cloth to prevent the valve from overheating. Do not braze with the valve body exceeding 250°F.

7)Install the new Drier.

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

9)See the Nameplate for the required refrigerant charge.

10)Cut the leads of the Solenoid allowing enough lead length to reconnect using closed end connectors.

11)Connect the new Solenoid leads.

12)Attach the Solenoid to the valve body, and secure it with a screw.

13)Replace the panels in their correct positions.

14)Turn on the power supply.

KML-200MWE, KML-200MAE specifications

The Hoshizaki KML-200MWE and KML-200MAE are commercial ice machines renowned for their high performance and reliability in the foodservice industry. Both models are designed to meet the needs of businesses that require a consistent supply of ice for various applications, including restaurants, bars, and hotels.

One of the standout features of the KML-200MWE and KML-200MAE is their ability to produce high volumes of crisp, clear ice. These machines utilize a combination of advanced refrigeration technology and a unique ice-making process that ensures a rapid ice production rate while maintaining energy efficiency. The modular design allows for easy integration into existing setups, making them an ideal choice for operators looking to expand their ice supply without a complete equipment overhaul.

The KML-200MWE features a built-in water-cooled condenser, allowing for operation in environments where air-cooled systems may not be viable. This feature is particularly useful in warm climates or kitchens with limited ventilation, as it ensures that the machine operates efficiently, regardless of external temperatures. In contrast, the KML-200MAE incorporates an air-cooled condenser, making it a more flexible option for operators who prioritize energy savings and ease of maintenance.

Both models utilize a unique fluorinated refrigerant, which not only enhances their cooling efficiency but also aligns with modern environmental standards. The internal components are constructed from high-quality stainless steel, ensuring durability and resistance to corrosion. Moreover, their easy-to-access design simplifies maintenance routines, enabling operators to keep the machines running smoothly with minimal downtime.

Another key feature of the KML-200MWE and KML-200MAE is their ice storage capacity. With an ample bin size, these machines can store a significant amount of ice, reducing the need for frequent refills and making them ideal for busy establishments. Additionally, they are equipped with automatic ice level controls, which help maintain optimal ice quantities while preventing overflow.

Hoshizaki ice machines are also recognized for their innovative air filtration systems, which improve the quality of the ice produced. This ensures that the ice is not only abundant but also free from any contaminants, meeting the high standards of hygiene expected in the food industry.

In summary, the Hoshizaki KML-200MWE and KML-200MAE are exemplary models that blend technology, efficiency, and durability. Their advanced features make them suitable for various commercial applications, providing operators with reliable performance and peace of mind. Whether choosing the water-cooled or air-cooled variant, businesses can expect a high-quality product that enhances their ice production capabilities.
