Food storage and loading
Wrap food or use sealed containers, leaving space between items and cabinet surfaces for airflow. Keep air inlets and outlets clear and place food on properly installed shelves, not the cabinet floor. Do not exceed 120 lb on any shelf. Let warm or hot food cool before loading and allow the cabinet to reach its operating temperature before stocking.
Use the freezer for food storage, not chemicals, vaccines or other medical supplies. Do not climb, stand or hang on the cabinet or doors. Keep additional equipment loads off the cabinet unless Hoshizaki has approved the intended installation.
Installation and electrical supply
Install indoors on a firm, level foundation, away from ovens, grills, high heat and corrosive environments. Retain the factory rear bumpers to maintain the required 1-inch rear clearance, and leave at least 1.5 inches above the unit for ventilation. Check the full door swing and service access before placement. Operate in a room within 45–100°F; installation above 6,561 feet (2,000 m) is not intended.
Have the installer follow the six-caster mounting arrangement for the 46-inch cabinet. All six casters must be fitted to prevent tipping, with locking casters at the front. Confirm the delivered caster package and use the complete required arrangement, not just the quantity in an optional caster kit. The installation requires a minimum room floor area of 3.6 m² (38.6 sq. ft.).
Have qualified personnel install the unit in accordance with the nameplate, instruction manual and applicable codes. Move the unit upright, do not tilt it more than 45 degrees, and do not lift by the refrigeration area, top or doors. Connect to an independent, properly grounded three-prong outlet. Do not use an extension cord or adapter or remove the grounding prong. If GFCI protection is required, use a GFCI breaker rather than a GFCI receptacle.
R-290 is flammable. Keep ignition sources away, do not puncture refrigerant tubing or use mechanical defrosting tools, and leave refrigeration service to qualified technicians. Keep ventilation openings clear during operation and storage.
Cleaning and maintenance
Unplug the freezer and transfer food to another suitable freezer before maintenance. Inspect the air filter every two weeks; wash with warm water and a neutral cleaner if dirty. Inspect the condenser twice yearly and clean with a brush or vacuum as needed. Dusty or greasy locations may require more frequent cleaning.
Wipe exterior surfaces with a soft cloth and neutral cleaner. Clean the cabinet interior and door gaskets with mild soap and warm water, and wipe up spills promptly. Use only stainless-steel-safe products on stainless surfaces; avoid steel wool, abrasives and chlorine bleach. Do not spray, splash or pour water into the unit. Allow the cabinet to return to operating temperature before restocking.
Optional accessories
Model-matched shelf options include HS-5152 epoxy-coated shelves and HS-5154 stainless steel shelves, supplied as single packs. Overshelf options are HS-5229 single and HS-5228 double. The HS-5514 pan-slide rack is also available. Accessories are sold separately; confirm the intended installation and clearances when selecting them.
