Ice Machine Operation

Section 3

 

 

Sequence Of Operation

NOTE: The toggle switch must be in the ice position and the water curtain must be in place on the evaporator before the ice machine will start.

INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF

1. Water Purge

Before the compressor starts, the water pump and water dump solenoid are energized for 45 seconds, to completely purge the ice machine of old water. This feature ensures that the ice making cycle starts with fresh water.

The harvest valve(s) is also energized during water purge, although it stays on for an additional 5 seconds (50 seconds total on time) during the initial refrigeration system start-up.

2. Refrigeration System Start-Up

The compressor starts after the 45 second water purge, and it remains on throughout the entire Freeze and Harvest Sequences. The water fill valve is energized at the same time as the compressor. The harvest valve(s) remains on for 5 seconds during initial compressor start- up and then shuts off.

At the same time the compressor starts, the condenser fan motor (air-cooled models) is supplied with power throughout the entire Freeze and Harvest Sequences. The fan motor is wired through a fan cycle pressure control, therefore it may cycle on and off. (The compressor and condenser fan motor are wired through the contactor. As a result, anytime the contactor coil is energized, the compressor and fan motor are supplied with power.)

FREEZE SEQUENCE 3. Prechill

The compressor is on for 30 seconds (60 seconds initial cycle) prior to water flow, to prechill the evaporator. The water fill valve remains on until the water level probe is satisfied.

4. Freeze

The water pump restarts after the prechill. An even flow of water is directed across the evaporator and into each cube cell, where it freezes. The water fill valve will cycle on and then off one more time to refill the water trough.

When sufficient ice has formed, the water flow (not the ice) contacts the ice thickness probe. After approximately 10 seconds of continual water contact, the harvest sequence is initiated. The ice machine cannot initiate a harvest sequence until a 6 minute freeze lock has been surpassed.

NOTE: Freeze lock is bypassed after moving the toggle switch from OFF to ICE position for the first cycle only.

The S1400M employs Manitowoc's advanced ice-making technology, which includes a state-of-the-art 100% stainless steel evaporator. This not only enhances the longevity of the unit but also helps produce cleaner and clearer ice. The unit utilizes a patented built-in actuator that completely purges the evaporator during the harvest cycle, ensuring that the ice is free from contaminants and undesirable residues.

Furthermore, the Manitowoc S1400M is designed with energy efficiency in mind. It operates with the Energy Star certification, which means it meets strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. This reduces operational costs and environmental impact, making the S1400M an excellent investment for eco-conscious businesses.

This model is also equipped with an intuitive ice thickness control system, allowing for customization of ice size according to specific needs. Users can easily set the machine to produce either half-cube or full-cube ice, catering to varying beverage requirements. Additionally, the S1400M features a user-friendly interface and digital display, providing operators with real-time machine status updates and alerts for maintenance or service needs.

Another important aspect of the S1400M is its flexible installation options. This unit can be paired with a variety of bins and dispensers, allowing businesses to optimize their space while ensuring the functionality of their ice supply. Its compact design is ideal for establishments with limited space, making it a versatile choice for bars, restaurants, and hotels.

In summary, the Manitowoc Ice S1400M represents the perfect blend of power, efficiency, and technological advancement. With its high production capacity, durable construction, customizable ice production, and energy-saving features, the S1400M stands out as a leading choice for any business requiring consistent and high-quality ice.
