Eskimo Ice Installation & Operation Manual
I -S
CE TORAGE
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.

EAWATER
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 10) 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 2.75 GPM / 10.4 LPM) or coil erosion
can occur.
F
RESHWATER
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 21 for maintenance
instructions.
R
EFRIGERANT
The unit is pre-charged with the correct amount of R-404A refrigerant. If service is required, see data plate for correct charge
amount.

HERMAL XPANSION
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.
