Hoshizaki KM-730MAK Buying Guide: 756 lb Output, 115V Installation and KM-622 Comparison
Quick answer
The Hoshizaki KM-730MAK is a 30-inch modular crescent-cube head rated for 756 lb/day at 70F/50F and 620 lb/day at 90F/70F. It combines high output with 115V electrical service, making it a notable option for operations that need more than a 600 lb-class machine but do not want 208-230V power.

Why the 620 lb warm-condition rating is the number to remember
The KM-730MAK's maximum rating is 756 lb/day, but Hoshizaki lists 620 lb/day at 90F air and 70F water. That is a 136 lb reduction in warmer conditions. For a busy restaurant or hotel, the 620 lb figure is the better starting point for sizing.
If your operation needs close to 600 lb on its busiest day, do not treat the remaining 20 lb as a comfortable buffer. Demand spikes, cleaning time and hot summer conditions can erase a narrow margin quickly.
High output on 115V power
The KM-730MAK operates on 115V/60/1 with 12.3A draw and a 20A maximum fuse or breaker. That gives operators a 700-plus-lb nominal machine without stepping into a 208-230V electrical configuration.
The machine is hardwired, so 115V does not mean it can simply be plugged into a nearby receptacle. The branch circuit, disconnect, wire sizing and local electrical code should be confirmed by the installer.
Crescent ice for broad beverage use
Like other Hoshizaki KM cubers, the KM-730MAK makes individual crescent-shaped cubes. They are a durable, general-purpose beverage ice that works across restaurants, hotels, cafeterias, banquet service and many bar applications.
If your program is built around chewable ice or food-display ice, do not choose a high-output cuber just because the production number works. Ice shape remains a primary purchasing decision.
Space, airflow and utilities
The head measures 30 inches wide, 24 inches deep and 26 inches high. Plan the total installed height with the selected storage bin and keep the manufacturer-required service and ventilation clearance around the air-cooled head.
Hoshizaki lists R290 refrigerant, 9,300 BTU/hr of heat rejection, 4.1 kWh per 100 lb of ice and 22 gallons of potable water per 100 lb at 90/70. Those numbers are useful for comparing operating load with nearby alternatives.
KM-730MAK vs KM-622MAK
The KM-622MAK is 22 inches wide and rated for 673 lb/day at 70/50 and 540 lb/day at 90/70. The KM-730MAK is 30 inches wide and raises those figures to 756 and 620 lb/day.
That gives the KM-730 about 80 lb/day more production under warm conditions, but it consumes eight additional inches of equipment width. If your site is narrow, the KM-622 can be a better fit. If your demand makes 540 lb/day feel too close for comfort, the KM-730 provides more breathing room.
Replacement opportunity for older KMD-705MAJ searches
Hoshizaki identifies KM-730MAK as the current replacement pathway for the discontinued KMD-705MAJ. Owners searching the older model should be routed to a current-model explanation that covers dimensions, output, electrical and bin compatibility rather than simply redirecting them to a product page.
As with any replacement, verify the existing bin/top kit and utility connections. A replacement recommendation is not the same thing as guaranteed drop-in compatibility for every installed system.
Who should choose KM-730MAK?
Shortlist this model when a 30-inch modular head fits the space and your operation needs a warm-condition capacity above the mid-500s. Restaurants, hotels, cafeterias and beverage-heavy operations are natural use cases.
Choose a smaller head if your demand is far below the warm rating, or move up in capacity if the 620 lb/day warm number does not leave a reasonable operating buffer.
KM-730MAK FAQ
How much ice does Hoshizaki KM-730MAK produce?
Up to 756 lb/day at 70F/50F and 620 lb/day at 90F/70F.
Is KM-730MAK 115V?
Yes. The current specification lists 115V/60/1, 12.3A and a 20A maximum fuse/breaker. The head is hardwired.
What are KM-730MAK dimensions?
The head is 30 inches wide, 24 inches deep and 26 inches high.
Does the KM-730MAK include a bin?
No. It is a modular head and requires a compatible storage bin or dispenser.
How does KM-730MAK compare with KM-622MAK?
KM-730MAK is wider and produces more ice: 620 lb/day vs 540 lb/day at the 90/70 warm-condition rating.
What refrigerant does KM-730MAK use?
The current model uses R290 hydrocarbon refrigerant.
Buying takeaway
Choose this model when you need more than the 600 lb class from a 30-inch crescent head while staying on 115V power.
