Door access and storage
The stepped door design protects the removable magnetic gasket during loading. The doors self-close with spring assistance and stay open past 90°. Field-reversible hinging allows the swing to be adapted to the installation.
Keep food in covered or sealed containers and leave space around containers and interior surfaces for airflow. Do not block cabinet air inlets or outlets. Load pre-cooled food only; keep items away from air outlets where freezing can occur. Adjust the control and verify food temperatures for the items being stored.
Installation and electrical requirements
Install indoors on a level surface away from direct sunlight and high-heat equipment. Retain the factory rear spacing hardware and allow at least 1.5 inches of overhead ventilation clearance. Keep ventilation paths clear and provide room for the door swing, power cord and service access.
Connect to a properly grounded dedicated receptacle matching the delivered-unit nameplate and supplied instructions; do not use an extension cord. If GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle. R290 is flammable. Provide at least 2.9 m² (30.9 sq. ft.) of room floor area and verify the delivered unit’s installation requirements before placement.
Cleaning and maintenance
Move stored food to another refrigerator and unplug the cabinet before cleaning or maintenance. Wipe stainless steel with a soft cloth and neutral cleaner, rinse with a clean damp cloth and dry. Clean removable door gaskets and shelves regularly. Avoid abrasive cleaners, steel wool, chlorine bleach and spraying water directly into the cabinet.
Inspect the condenser twice a year and clean it with a brush or vacuum when needed; more frequent cleaning may be necessary in dusty or greasy locations. Keep cabinet airflow paths unobstructed and use a qualified service professional for refrigeration or electrical work.
