b) Connection to a Closed Loop System

•Condenser water supply inlet is 1/2" female pipe thread (FPT). A minimum of 1/4" nominal

ID copper water tubing or equivalent is required for the condenser water supply line.

•Condenser return outlet is 3/8" FPT. A minimum of 1/4" nominal ID copper water tubing or equivalent is required for the condenser return line.

•Shut-off valves and drain valves should be installed at both the condenser water supply inlet and condenser return outlet.

•The water supply to the condenser should not drop below 4 GPM.

•The pressure differential between the condenser water supply inlet and condenser return outlet must be no less than 10 PSIG.

•When using a glycol blend, the solution mixture should be less than 30% glycol.

•In order to maintain the proper high side pressure, the condenser water supply inlet temperature should not drop below 45°F (7°C) and the condenser drain outlet temperature must be in the 104°F to 115°F (40°C to 46°C) range. Once the icemaker installation

is complete, confirm the condenser drain outlet temperature 5 minutes after a freeze cycle starts. If the condenser drain outlet temperature is not in the proper range, use a flat blade screwdriver to rotate the adjustment screw on the water‑regulating valve until the temperature is in the proper range (rotate counterclockwise to raise temperature or clockwise to lower temperature).

DCM-751BWH(-OS), DCM-751BAH(-OS) specifications

The Hoshizaki DCM-751BAH(-OS) and DCM-751BWH(-OS) are innovative ice makers tailored for high-demand settings like restaurants, bars, and convenience stores. Known for their reliability and efficiency, these models are designed to meet the rigorous demands of professionals in the food service industry.

One of the standout features of both models is their ability to produce high volumes of crescent ice. Crescent ice is known for its versatility, ideal for cooling beverages quickly and providing a pleasant aesthetic in drinks. One of the primary advantages of crescent ice is its density, which allows for slower melting, thus ensuring drinks maintain their desired temperature without becoming diluted.

The DCM-751BAH(-OS) and DCM-751BWH(-OS) models utilize a state-of-the-art refrigeration system that emphasizes energy efficiency. Both machines are equipped with Hoshizaki’s exclusive “EverCheck” monitoring system, which continuously checks the operation of the machine, alerting users to potential issues before they lead to malfunction. This technology not only extends the lifespan of the ice maker but also guarantees a consistent supply of high-quality ice.

In terms of design, these models feature a durable stainless-steel exterior and an easy-to-clean hygienic design. This stands out in commercial environments where cleanliness and sanitation are paramount. The compact footprint of both units makes them suitable for establishments with limited space, while still providing an impressive ice production capacity.

Furthermore, the DCM-751BAH(-OS) and DCM-751BWH(-OS) are differentiated by their operational features. The ‘BAH’ model includes an ambient air sensor that adjusts ice production based on surrounding temperatures, while the ‘BWH’ version focuses on water efficiency, reducing waste and optimizing water usage—a key benefit for eco-conscious operations.

Both models also incorporate advanced insulation to maintain ice quality and minimize the need for extensive energy consumption. Additionally, maintenance is simplified with easily removable components, allowing for quick access during cleaning and servicing.

In summary, the Hoshizaki DCM-751BAH(-OS) and DCM-751BWH(-OS) ice makers exemplify the perfect blend of cutting-edge technology, user-friendly features, and robust design. Their ability to provide high-quality ice consistently ensures that food service professionals can focus on what they do best, while the machines take care of their ice needs efficiently and effectively.
