This document is a user manual for the SUMMIT® BIM44 G Automatic Undercounter Ice Maker, providing detailed information on its function, installation, operation, and maintenance.

Function Description:

The SUMMIT® BIM44 G is an automatic undercounter ice maker designed to produce hard, crystal-clear, gourmet cube ice. It is suitable for both homeowners and hotel guests, offering convenience with its built-in insulated ice storage bin. The unit requires an external drainage system for operation. It is designed and manufactured to meet or exceed UL563 safety standards and NSF12 sanitation standards. The ice maker operates through distinct freeze and harvest cycles. During the freeze cycle, the compressor pumps refrigerant, the fan motor blows air, and the water pump circulates water to the evaporator surface, where water freezes into ice cubes. Once a batch is fully formed, the harvest cycle begins, where the hot gas valve opens to divert hot refrigerant gas into the evaporator, warming it and causing the ice cubes to slide into the storage bin. The machine automatically stops making ice when the storage bin is full, indicated by a bin-full probe. It resumes ice production once ice is removed and the probe returns to its operating position. A pump water drain system is integrated, which activates for 20 seconds to pump out excess water from the reservoir when the water level reaches its maximum.

Usage Features:

The ice maker is designed for mobile (free-standing), enclosed (under a cabinet), or built-in installations, requiring adequate front air space for ventilation. It needs a continuous cold water supply (¼-in. soft copper tubing with a shut-off valve) with a minimum pressure of 15 psig and a static pressure not exceeding 80 psig. The water temperature should be between 41°F (5°C) and 90°F (32°C) for proper operation. A water filter is strongly recommended to remove taste, odors, and particles, though deionized water is not. The unit must be properly leveled for correct water flow over the evaporator. The door swing can be reversed if needed. The control panel features LED indicators for "ICE" (green, ice making in progress), "HARVEST" (yellow, ice harvesting in progress), and "BIN FULL" (red, ice storage bin is full or probe is blocked). An "ON/OFF" button initiates operation. A "CLEAN" button activates the automatic cleaning cycle. An "ADJUST" button allows for ice cube size adjustment (smaller with "CLEAN" button, larger with "MODE" button). A "MODE" button is primarily for service, switching between ice making and harvest modes. The unit includes a bin light (if present) controlled by a magnetic reed switch, turning on/off with the door. It also features a sensitive probe and precise timer for enhanced performance and a compressor protection system.

Maintenance Features:

Regular cleaning and maintenance are crucial for efficiency, top performance, and long life. The manual outlines cleaning procedures for five key areas:

Exterior Cleaning: The door and cabinet can be cleaned with a mild detergent and warm water solution. Solvent-based or abrasive cleaners should be avoided. Stainless steel panels should be cleaned with a mild detergent and damp cloth to prevent discoloration from chlorine gas and moisture.
Interior Cleaning: The ice storage bin should be sanitized occasionally. The water trough should be cleaned before initial use and after extended periods of inactivity. This involves disconnecting power, removing the ice storage bin, cleaning the interior with a sanitizing solution (e.g., 1 ounce of household bleach in 2 gallons of hot water), rinsing, and drying. The ice scoop should also be washed regularly.
Condenser Cleaning: A dirty or blocked condenser can reduce ice production and lead to component failure. It should be cleaned at least every six months by disconnecting power, removing the front lower grille, and using a brush or vacuum cleaner to remove dirt and lint. Care should be taken not to touch the sharp condenser fins.
Water Distribution Tube Cleaning: If ice cubes are incompletely formed or production is low, the water distribution tube may be blocked. It can be cleaned by removing it, locating the holes, and clearing them with a pointed object like a toothpick. For thorough cleaning, the tube can be disconnected, removed, cleaned with a diluted solution of warm water and mild detergent, rinsed with pure water, and reinstalled.
Ice-making System Cleaning: Mineral deposits can accumulate in the water system. The system should be cleaned regularly (e.g., every 6 months for hard water). This involves ensuring the evaporator is clear of ice, adding 8 ounces of Nickel-Safe Ice Maker Cleaner Solution to the water trough, and pressing the "CLEAN" button to initiate an automatic cleaning cycle. After 30 minutes, the dirty water should be drained, and the system rinsed three times with clean water. A sanitizing solution (1 ounce of household bleach in 2 gallons of hot water) should then be used to wipe down the bin interior and exterior, sprayed into corners and edges, left for 3 minutes, and dried. The system should be rinsed again with clean water, and the first batch of ice after cleaning should be discarded.

For long storage, the system should be drained of water by shutting off the main water supply and electrical supply, disconnecting the water supply line, removing and drying the ice storage bin, draining the water trough, and leaving the door open to prevent mold and mildew.
