Storage access
Anodized aluminum shelf supports let you change shelf height in ½-inch increments. The stepped door design helps protect the gasket during loading. The stay-open position supports restocking, while spring-assisted closing returns the door after routine access.
Installation and electrical planning
Install indoors on a firm, level floor, away from ovens, grills and other high-heat equipment. Retain the factory rear spacing hardware and allow at least 1.5 inches above the cabinet for ventilation. Keep the front airflow path clear. Check the delivered-unit dimensions, counter opening, delivery route and fully open door clearance before installation.
Provide an independent, properly grounded 115V circuit with a matching NEMA 5-15P receptacle. Have a qualified installer check the delivered-unit nameplate and installation manual. Do not use an extension cord. If GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle. R290 is flammable; follow the manual’s room-size and placement requirements and keep ignition sources away.
Cleaning and maintenance
Move frozen food into suitable cold storage, turn the unit off and unplug it before cleaning. Wipe the cabinet and gaskets with a soft cloth and neutral cleaner, then dry the surfaces. Avoid abrasive pads, acids and chlorine bleach. Inspect the condenser twice a year and clean it with a brush or vacuum when needed. Keep drainage and airflow paths clear, and use qualified technicians for refrigeration service.
Compare Steelheart undercounter freezers

The glass-door model adds visibility and interior lighting; solid-door -01 models include factory-installed cylinder locks. Models are sold separately.
