COMPONENTS OF THE ICE MAKER

ICE-MAKING UNIT

The ice-making unit has an R-404A compressor, seawater-cooled condenser, a filter/drier, and an accumulator. The auger

assembly contains the evaporator barrel, auger rotor, gearbox, motor, water reservoir, and expansion device.

The freshwater delivered to it is converted to ice which exits the system via an ice-delivery hose routed properly to a storage box

up to 35 feet (10.6m) away. See Figure 4 on page 6.

The unit is pre-charged with refrigerant from the factory. The unit has plug-and-play electrical connections for the ice-level

sensor and the optional remote display.

CONTROL BOX

The ice-making unit has an electrical control box with digital display that can be mounted on the unit or remotely mounted up to

7’ (2.1m) away.

The control box (Figure 11, page 12) contains the system function switches, digital display, and system indicator lights. It lets

you control all system operations and provides visual indications of system activity, such as whether the system is running or

has a fault. If a fault condition is detected, the system shuts down automatically. The control panel lets you restart the system

after a sustained fault. See the “The Digital Control” on page 12 for further operating instructions.

ICE-STORAGE BOX

The ice-storage box is the destination point where the ice will accummulate via the ice-delivery hose. An ice-level sensor

installed in the storage box halts ice production when the box is full.

The ice-storage box should be able to hold water and have at least 2" (51mm) of insulation to keep the ice frozen as long as

possible. It is helpful to install a drain in the box at the end opposite from the ice input. To improve ice-production performance,

keep the drain plugged to prevent cold air and cold water from escaping the storage box.

SEAWATER SYSTEM

Seawater is pumped into the ice-making unit to efficiently cool the hot refrigerant via a cupronickel coaxial tube design. The

condensing unit may be connected to its own single-station pump or to a larger, multi-station pump via a pump relay box.

The seawater system (Figure 7, page 9) consists of a thru-hull fitting, seacock, strainer, seawater pump, seawater hose, and

overboard discharge. There must be water flow of at least 2 GPM / 7.6 LPM(maximum 3.5 GPM / 13.2 LPM) or coil erosion can

occur.

FRESHWATER SUPPLY

Use the 1/4" SAE male flare fitting on the auger unit to supply freshwater for ice making. Provide water with pressure of at least

15 PSI. An in-line water filter (included in kit) is mandatory to comply with Dometic Warranty Regulations, to help prevent

clogging of the needle valve in the water reservoir, and to help keep the auger walls from fouling with mineral deposits which will

cause premature failure of water seals and bearings. See “Fresh Water Filter and Y Strainer” on page 19 for maintenance

instructions.

REFRIGERANT CHARGE

The unit is pre-charged with the correct amount of R-404A refrigerant. If service is required, see data plate for correct charge

amount.

THERMAL EXPANSION VALVE (TXV)

The TXV is used as the expansion valve of the refrigerant system. It allows high-pressure liquid to become low-pressure liquid

and start the refrigeration process. The simple and reliable TXV provides a load-modulated system pressure over a wide range

of ambient and seawater temperatures. The TXV is not adjustable.
