c) Drain Timer (S1 dip switch 3 & 4)

Once every ten freeze cycles, the drain valve opens to drain the water tank for the time determined by the drain timer. These switches also determine the time to delay completion of a defrost cycle, i.e. the minimum defrost time.

Do not change this setting, or the unit will not operate properly or produce high quality ice.

T1: Time to drain the water tank

T2: Harvest timer at drain

Drain cycle always occurs on the 2nd harvest after startup. Then, depending on the drain frequency control setting (dip switch 5 & 6), drain cycle occurs every cycle, or every 2nd, 5th, or 10th cycle.

d) Drain Frequency Control (S1 dip switch 5 & 6)

The water tank drains at the frequency set by the drain frequency control.

The drain frequency control is factory-adjusted to drain the water tank every 10 cycles, and no adjustment is required. However, where water quality is bad and the icemaker needs a drain more often, the drain frequency can be adjusted as shown in the table below.

e) Water Saver Timer (S1 dip switch 7 & 8)

The water saver timer allows the water valve to close and the pump motor to circulate water in the tank during the final part of harvest. The water valve is open during harvest for a maximum of 6 minutes or the length of harvest minus 0, 10, 30, or 50 seconds (determined by the water saver timer setting), whichever is shorter. When the water valve closes, the pump motor energizes and runs for the time determined by the water saver timer setting.

The water saver timer is factory-adjusted, and no adjustment is required.

KMD-410MWH, KMD-410MAH specifications

The Hoshizaki KMD-410MWH and KMD-410MAH are premier ice makers, designed for commercial establishments that require high-efficiency ice production. These units stand out for their advanced features and technology that cater to the diverse needs of restaurants, bars, and hotels.

One of the primary features of the KMD-410 lineup is its impressive ice production capacity. With a production rate of up to 410 pounds of cube ice in a 24-hour period, each model ensures a steady supply of ice, which is essential for businesses with high demand. The ice produced is in the form of clear, hard cubes, ideal for beverage cooling, cocktail preparation, and food presentation.

Both models showcase the unique Hoshizaki ice-making system, which employs a direct cooling method. This technology uses individual stainless steel evaporators to produce ice, resulting in more uniform cubes and less waste. The stainless steel construction contributes to the durability of the units, making them suitable for rugged commercial environments.

Energy efficiency is another hallmark of the KMD-410MWH and KMD-410MAH. These machines are designed with an energy-saving mode that reduces power consumption without compromising ice production. This is critical for businesses looking to minimize operational costs while maintaining high standards of service.

User convenience is prioritized in these models through features like the easy-to-clean design. The internal components can be accessed quickly, allowing for simpler maintenance and sanitation processes. Additionally, the built-in cleaning cycle aids in maintaining ice purity and preventing bacterial growth, which is essential for food safety.

The KMD-410MAH also includes an advanced monitoring system with indicators for water usage and ice levels. This feature allows operators to keep track of performance and make necessary adjustments, ensuring that the ice maker operates at peak efficiency.

For installation flexibility, both models can be paired with various storage bins and dispensers, adapting to the layout of any establishment. Furthermore, they can be equipped with optional filtration systems that enhance water quality, further improving the taste and clarity of the ice produced.

In summary, the Hoshizaki KMD-410MWH and KMD-410MAH ice makers are exemplary choices for any business that demands high-quality, reliable ice production. Their robust features, energy-efficient operation, and user-friendly design make them indispensable assets in the hospitality and foodservice industries.
