Hoshizaki KM-622MAK Buying Guide: Specs, Capacity, Installation and Best Uses
Quick answer
The Hoshizaki KM-622MAK is a narrow 22-inch modular crescent-cube ice machine rated for 673 lb/day at 70F air and 50F water and 540 lb/day at 90F air and 70F water. It is a strong fit when floor width is limited but the operation still needs roughly 500-plus pounds of warm-condition capacity.

Why the KM-622MAK stands out in the 600 lb class
Commercial ice machines near this output usually force buyers to choose between capacity and footprint. The KM-622MAK is unusual because Hoshizaki packages a 673 lb/day rating into a 22-inch-wide head. That makes the model especially relevant for crowded kitchens, beverage stations and replacement projects where a 30-inch head is difficult to place.
The machine is head-only, so daily production and ice storage must be sized separately. That flexibility is useful when your rush-period demand is high, but it also means the bin, top kit and final installed height need to be planned before the order is placed.
Read both production ratings before sizing the machine
Hoshizaki rates the KM-622MAK at 673 lb per 24 hours at 70F air and 50F water. At the hotter 90F air and 70F water condition, the rating is 540 lb per day. For a warm restaurant kitchen, the 540 lb figure is the safer planning number because it better reflects the load created by warm air and warmer incoming water.
The difference between 673 and 540 lb/day is 133 lb, or about 20 percent. If your busiest-day demand is already close to 540 lb, do not treat the headline 673 lb figure as spare capacity. Add a realistic demand buffer and account for cleaning, filter changes and future growth.
Crescent ice: where it works best
The KM-622MAK produces Hoshizaki crescent ice. The individual cubes have a hard, curved shape that works well for water, soft drinks, iced tea and general beverage service. Crescent ice is also a familiar choice in restaurants and hotels that want a solid cube without moving to a full-dice format.
Ice type should be selected before brand or model. If your customers specifically want soft chewable ice, a nugget or cubelet machine is a better match. If the goal is dependable beverage ice with a relatively slow melt, the KM-622MAK is in the right category.
Installation requirements to confirm before ordering
This model uses 115V single-phase power but it is not a simple countertop plug-in appliance. The current Hoshizaki specification calls for 14.6A and a maximum 20A fuse or breaker, with the unit hardwired at installation. A qualified installer should confirm the branch circuit, disconnect requirements and local code before delivery.
Hoshizaki also specifies a potable water connection, gravity drain, and operating limits of 45-100F ambient air, 45-90F incoming water and 10-113 psig water pressure. The current specification recommends about 6 inches of clearance at the rear, sides and top for airflow and service access.
Choose the storage bin as carefully as the machine head
The KM-622MAK can be paired with several Hoshizaki bins and dispensers. Current Hoshizaki literature lists options including B-250SF, B-300SF, B-500/SF, B-700SF, B-800SF and larger bins, plus selected dispensers. A top kit may be required depending on the combination.
Do not size the bin only by the machine's 24-hour production. Storage should cover the amount of ice your operation needs ready at the start of a rush plus the time it takes the machine to recover. A restaurant with concentrated dinner demand may need more stored ice than a business with demand spread evenly across the day.
KM-622MAK vs KM-522MAK
The closest same-footprint comparison is the Hoshizaki KM-522MAK. Both are 22 inches wide, 27.375 inches deep and 28 inches high, and both use 115V power. The KM-522MAK is rated at 548 lb/day at 70/50 and 445 lb/day at 90/70; the KM-622MAK raises those figures to 673 and 540 lb/day.
That means the KM-622MAK gives about 95 lb/day more warm-condition production without increasing cabinet width. The tradeoff is higher electrical draw: 14.6A for the KM-622MAK versus 10.8A for the KM-522MAK. If your ice demand fits comfortably below the KM-522MAK's warm rating, the smaller model may be enough; if margin is tight, the KM-622MAK provides more production in the same narrow footprint.
Who should shortlist the KM-622MAK?
This model makes the most sense for operations that need high production but have a narrow equipment line: restaurants, hotel beverage operations, bars, cafeterias and other foodservice sites with a compatible bin or dispenser. It is also compelling when replacing a lower-output 22-inch head and the existing location cannot accept a wider cabinet.
Choose a different machine if you need built-in storage, soft nugget ice, a plug-in undercounter solution, or output materially above the KM-622MAK's 540 lb/day warm-condition rating.
KM-622MAK FAQ
How much ice does the Hoshizaki KM-622MAK make?
It is rated for up to 673 lb/day at 70F air and 50F water and 540 lb/day at 90F air and 70F water. Use the warmer rating when planning for a hot foodservice environment.
Is the KM-622MAK only 22 inches wide?
Yes. The current cabinet is 22 inches wide, 27.375 inches deep and 28 inches high, which is a major reason this model is attractive in narrow equipment layouts.
Does the KM-622MAK include an ice bin?
No. It is a modular ice machine head. A compatible storage bin or dispenser, and any required top kit, must be selected separately.
Does the KM-622MAK plug into a standard outlet?
The current specification lists 115V/60/1 power, 14.6A and a 20A maximum fuse/breaker, but the unit is hardwired. Have the installer verify the electrical connection before delivery.
What is the difference between KM-622MAK and KM-522MAK?
They share the same 22-inch cabinet dimensions. The KM-622MAK has higher production: 673 vs 548 lb/day at 70/50 and 540 vs 445 lb/day at 90/70.
What refrigerant does the KM-622MAK use?
The current model uses R290 hydrocarbon refrigerant with a 5.3 oz charge.
Buying takeaway
Choose this model when you need unusually high production from a 22-inch modular crescent-cube head and the 540 lb/day warm-condition rating leaves a healthy reserve.
