Hoshizaki R3A-HS 79.03 cu. ft. Stainless Steel 3-Section Reach-In Refrigerator with 6 Half-Height Doors

Product overview

The Hoshizaki R3A-HS Steelheart reach-in refrigerator provides 79.03 cu. ft. of refrigerated storage in a three-section cabinet. Its 6 half-height doors let staff open the upper or lower storage area separately.

9 epoxy-coated main shelves adjust in 1-inch increments to accommodate different containers. Interior LED lighting helps staff locate ingredients, and the stainless steel interior and exterior front, sides and top support daily kitchen use. A top-mounted, self-contained refrigeration system leaves the cabinet ready for a standard cord-and-plug electrical connection.

Specifications

Storage access and temperature control

The stainless steel doors have recessed, full-length aluminum handles and heavy hinge plates with welded hinge pins. A stepped door profile helps protect the magnetic gaskets during loading.

Use the adjustable shelving to organize containers while keeping the internal air passages clear. The ducted airflow system distributes refrigerated air through the cabinet. A thermostatic expansion valve controls refrigerant flow, while temperature and voltage alarms help staff identify conditions needing attention. The top-mounted condenser filter is accessible for routine maintenance, and hot-gas condensate evaporation handles collected moisture.

Installation and electrical planning

Install indoors on a level, supporting floor. Allow at least 3 inches behind the cabinet, plus clear working space for opening the doors and loading shelves. The side and top minimum is 0 inches, but ventilation and access to the top filter and refrigeration components must remain unobstructed.

Connect the supplied three-prong plug to a properly grounded, independent 115V outlet. Do not use an extension cord. Have a qualified installer verify the delivered-unit nameplate, circuit capacity and local requirements. If GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle.

R290 is a flammable refrigerant. Provide at least 6.2 m² (67 sq. ft.) of room floor area and do not install this refrigerator in a public corridor or lobby. Follow the installation manual for placement and refrigerant safety. Select the temperature setting for the food being stored rather than treating the controller’s complete adjustment range as a universal food-holding range.

Cleaning and maintenance

Move food to another refrigerator, switch the unit off and unplug it before cleaning. Clean the cabinet and removable gaskets with suitable mild cleaning products, without damaging stainless steel surfaces or refrigerant tubing. Inspect the air filter at least twice a month and wash it with warm water and neutral cleaner when dirty. Inspect the condenser twice a year; clean it at least annually and sooner as needed. Clean the condenser wick at least annually. Increase maintenance frequency in dusty or demanding kitchens, and use qualified technicians for refrigeration service.
