• Refrigerant: R-404A (older models), transitioning to R-290 (propane) in EcoX models (e.g., MF46 AS OX) or R-452A, with a low global warming potential (GWP) of 3, compliant with F-Gas regulations.
• Condensing System: Available in air-cooled (AS), water-cooled (WS), or air-cooled remote versions. Air-cooled models feature top exhaust airflow, requiring no side clearance (22-inch footprint).
• Water Requirements:
  • Minimum water temperature: 5°C
  • Maximum water temperature: 38°C
  • Minimum water pressure: 1 bar (14 psi)
  • Maximum water pressure: 5 bar (70 psi)
  • Water consumption: ~100–120 liters/24 hours (air-cooled), higher for water-cooled models.
• Drainage: Gravity drainage (20 mm diameter sump drain at floor level). No built-in Progressive Water Discharge (PWD) system; optional Easy-Fit drain pump available.

Key Features

1. Flake Ice Production:
   • Produces granular flake ice (75–85% hardness, 15–25% residual water content) by freezing a thin layer of water on a horizontal evaporator drum, scraped off by a revolving AISI430 stainless steel auger. Ideal for food displays (e.g., seafood, superfoods), cocktails, smoothies, and medical applications (e.g., physiotherapy ice packs, organ transportation).
   • Flake ice’s rapid cooling and moldability make it suitable for fisheries, laboratories, and food processing.
2. Design and Build:
   • Grade 304 Stainless Steel Exterior: Corrosion-resistant, durable, “scotch-brite” finish with rounded corners for enhanced aesthetics and hygiene.
   • Compact Footprint: Global standard 22-inch (538–564 mm) footprint, with top exhaust airflow requiring no side clearance (minimum 15 cm at sides and back for ventilation and utility connections).
   • Head-Only Design: Requires a separate storage bin (e.g., SB193S, SB322S, FOL600, NB 530, NB 948), allowing customizable storage solutions. Top cover in PS plastic, with removable side panels on all four sides for easy maintenance.
3. Maintenance and Hygiene:
   • XSafe Sanitation System: Integrated 24/7 natural UV-based sanitation, standard since September 2020, destroys 99% of bacteria and viruses, including COVID-19, preventing mold, mildew, slime, and odors.
   • AgION Technology: Built-in antimicrobial protection in plastic components resists microbe growth and odor development.
   • Clean Alert: External indicator lights blink to signal when cleaning is required.
   • Front-Access Condenser Air Filter: Removable and washable, recommended for monthly cleaning to maintain performance and extend machine life.
   • One-Touch Cleaning: Initiated via electronic controls, using Scotsman Ice Machine Cleaner (300–350 ml in 3 liters of lukewarm water, max 40°C), followed by automatic rinsing, reducing labor costs.
   • Regular Bin Sanitization: The bin interior, in contact with food-grade ice, should be cleaned and sanitized weekly with a commercial food-grade sanitizer.
   • Sturdy Evaporator and Ice Breaker: Stainless steel AISI304 evaporator and specially strengthened alloy ice breaker with reduced-maintenance, self-lubricating gear reducer, allowing greater extrusion pressure for dryer ice (85% dry).
4. Ease of Use:
   • Electronic Controls with Self-Diagnostic Functions: External indicator lights monitor operations (reset/washing, alarm, bin full, operation, power supply), ensuring constant surveillance and fast diagnosis. Equipped with an electronic control board.
   • Plug-and-Work Technology: No-cycle harvesting system ensures continuous ice production, minimizing downtime.
   • Water In/Ice Out Concept: Matches water consumption to ice production, limiting excess energy, water, and time wastage.
   • Double Protection: Electronic rotation sensor and drive coupling on gear motor and gear reducer, with low-water sensor protection on refrigeration and gear motor systems. Optical ice level sensor for machine shutdown.
5. Optional Easy-Fit Drain Pump:
   • Available to pump excess water up to 15 meters away, enhancing installation flexibility for sites without floor-level drainage.

Applications

• Ideal for foodservice (cocktails, smoothies, seafood displays), medical (physiotherapy ice packs, organ transportation), laboratories, and food processing (preservation of perishables like fish or superfoods). Suitable for hospitals, fisheries, restaurants, and catering businesses.
• Flake ice’s rapid cooling and moldability make it perfect for maintaining freshness and natural appearance in refrigerated perishables. Large production facilities like fish processors can install the MF46 to dispense ice directly into storage cold rooms, maximizing productivity.

Operational Considerations

• Environmental Conditions: Operates effectively in ambient temperatures from 10°C to 43°C and water temperatures from 5°C to 38°C.
• Installation Requirements: Requires a permanent water supply (3/4” inlet), gravity drainage (20 mm sump drain at floor level), and connection to a neutral wire and solid earth ground to prevent electrical shock or equipment damage. Optional Easy-Fit drain pump available. Must be installed by a qualified refrigeration engineer. Suitable for stacking with another MF46 for doubled output (requires Scotsman stacking kit).
• Recommended Water Filter: HF40-S or HF60-S water filter recommended to remove particulates, chlorine taste, odor, cysts, and scale, maintaining ice quality and machine performance. Failure to use a filter may affect warranty.
• EcoX Initiative: Newer models (e.g., MF46 AS OX) use R-290 or R-452A refrigerants, replacing R-404A, for environmental compliance with lower GWP.
• Superseded Model: The MF46 has been replaced by the Scotsman MF47 (320–330 kg/24 hours) in some regions, with similar specifications. Verify model availability before ordering
