YRU0280A-161

Overview

The Atosa YRU0280A-161 is a self-contained undercounter ice machine for commercial foodservice. Its air-cooled condenser makes up to 280 lb of ice per 24 hours, while the integrated bin stores up to 88 lb. The unit has a stainless steel exterior and a slanted blue plastic bin door. It can be used freestanding or built in, provided the installation location allows the air circulation and connections required by the manual.

The machine produces half-diced cube ice measuring 3/8 x 7/8 x 7/8 inches. Atosa’s specification sheet lists a 280 lb per 24-hour ice-making capacity; the YR-series manual gives YR280 production figures of 283 lb at 70°F ambient temperature, 225 lb at 90°F and 201 lb at 100°F, with 70°F water. Actual output depends on the stated operating conditions.

Installation & Requirements

The Atosa YR-series manual calls for a level installation, connected water inlet and drain hoses, and a supply voltage checked against the machine rating plate. The YRU0280A-161 specification sheet states 115/60/1 power, 8.6A rated current and a standard NEMA 5-15 plug. The manual warns against using an extension cord and states that electrical work must comply with applicable local and national requirements. Installation and repair involving electrical components or refrigerant are for properly trained technicians.

Connect the water inlet using the 3/8-inch slip-style connection, which accepts 3/8-inch OD tubing. The outlet uses a 3/4-inch hose barb and accepts a 3/4-inch rubber hose; a hose clamp is required. A drain is required, and the manual specifies that drain hoses should slope down toward the floor drain by 2.5 cm per metre. It also says the ice machine and bin drains should be separate where applicable. The bin drain is incorporated in this model’s water outlet, according to the Atosa specification table.

The water supply must meet drinking-water standards. The manual advises installing a pressure relief or pressure-limiting valve if water pressure exceeds 80 psi; it also advises a booster where pressure is below 20 psi. The included 3M water filter system and cartridge should be installed. The manual cautions against installing the filter on a hot-water line, gives a maximum filter operating water temperature of 100°F and says not to install it where water pressure exceeds 125 psi. Follow the filter instructions and applicable plumbing codes.

Operation

Before starting, confirm that the machine is level, the water inlet and drain are connected, water is available and the supply voltage matches the rating label. The YR-series manual describes connecting power, then toggling the switch to the on position. It states that the green LED flashes during startup; the hot-gas valve opens for 10 seconds before the compressor is energized. Use the switch’s ice position for ice production. The unit requires a drain during operation.

The manual advises not to overload the machine. Keep the air inlet and outlet clear so the air-cooled condenser can reject heat. For the YR280 production figures shown in the manual, output changes with ambient temperature: 283 lb per 24 hours at 70°F, 225 lb at 90°F and 201 lb at 100°F, with water at 70°F. These figures are operating-condition data, not a guarantee of the same output in every kitchen.

Cleaning & Maintenance

Atosa’s specification sheet says to clean the condenser frequently and keep the unit supplied with fresh air. The removable air filter can be washed; the manual calls for frequent filter cleaning. The manual states that routine adjustments and maintenance are not covered by the warranty and that the owner or operator is responsible for maintaining the machine according to its instructions.

Clean and sanitize the ice machine and bin at least once every three months. If the machine needs more frequent cleaning, the manual recommends having water quality tested by a qualified service company. Discard all ice produced during cleaning and sanitizing. The procedure removes mineral deposits from surfaces that contact water. Wear rubber gloves and safety goggles or a face shield when handling cleaner or sanitizer, and do not mix the two solutions.

For the cleaning cycle, the manual instructs operators to remove ice from the evaporator and bin, switch the machine to clean, allow the water trough to refill, and add the proper amount of ice-machine cleaner. It lists two packs of Kay Delimer for the YR280 model. After the clean cycle, disconnect power before removing parts for cleaning. Use a soft-bristle nylon brush, sponge or cloth; do not use a wire brush. Rinse cleaned components and food-zone surfaces with clean water. Then prepare sanitizer according to its label, apply it to removed components and food-zone surfaces, and follow the manual’s sanitizing procedure. All ice from the process must be discarded.

For exterior cleaning, wipe dust and dirt with a damp cloth. For greasy residue, use a damp cloth with mild dish soap and water, then dry with a clean, soft cloth. Do not use steel wool, abrasive pads, or chlorinated, citrus-based or abrasive cleaners on the exterior panels and plastic trim. The manual recommends changing the included 3M cartridge every six months; timing may vary with water quality.

Troubleshooting

• Machine does not operate: Check for electrical power. The manual lists replacing a fuse, resetting a breaker or turning on the main switch as corrective checks. If the high-pressure cutout trips, clean the condenser coil.
• Machine stops and can be restarted at the switch: The manual identifies a safety-protection feature as a possible cause and directs the operator to the safety-protection section.
• Ice does not release or harvest is slow: The manual lists a dirty machine as a possible cause and calls for cleaning and sanitizing.
• Ice machine does not cycle into harvest: The manual lists an unexpired six-minute freeze-time lock-in, a dirty ice-thickness probe, a probe shorted to ground, or an incorrectly adjusted probe. Wait for the lock-in period, clean and sanitize, disconnect a probe shorted to ground, or adjust the probe as appropriate.
• Uneven ice fill or thin ice at the middle of the evaporator: Verify there is sufficient water in the sump trough. The manual advises contacting a qualified service company to check the refrigeration system if the problem continues.
• High-pressure protection: The manual lists a dirty condenser, excessive ambient temperature, an open or faulty high-pressure switch, a fan motor that is not running, or refrigeration-system failure. Clean the condenser where applicable; contact service for component or refrigeration faults.
• Water-lack protection: Check for absent water supply, a closed water ball valve, a leak from the trough, an inlet-valve issue or a water-probe issue. The manual recommends service attention for component faults.

The manual warns that installation and repairs involving high voltage or refrigerant must be performed by properly trained technicians. Use qualified service personnel for electrical, refrigeration and component faults.

Applications

The built-in bin and undercounter format suit commercial kitchens, bars, cafés and other foodservice work areas that need on-site half-diced cube ice without a separate storage bin. The 88 lb storage capacity supports service between production cycles, while the freestanding or built-in installation options provide flexibility for different kitchen layouts.
