Eskimo Ice Installation & Operation Manual
Requirements
•
Supplied feedwater must have a pressure of at least 15 PSI.
•
The water system must be able to supply at least 4 GPH when the ice maker is operating.
•
Install the in-line filter (supplied in kit) just prior to the unit to remove sediment which may clog the needle valve in the
water reservoir.
•
Dometic recommends installing a shut-off valve in the feedwater line between the source and the filter to facilitate filter
changes.
WARNING
Use of saltwater as feedwater will damage auger components and evaporator barrel and will void the
warranty.
WARNING
Failure to install and use the water filter included with the installation kit will void the warranty.
Note, if unit is purchased separately you must also purchase the water filter to maintain warranty.
Procedure
1.
Run copper tubing or equivalent from the freshwater source to the in-line water filter.
2.
Run copper tubing or equivalent from the water filter to the water input, and connect with the supplied 1/4" SAE male
flare connection on the unit.
3.
Ensure there are no leaks in the field-installed portion of the system.
Water Quality and Filters
No water from a municipality is "pure" feedwater, but water from a vessel's onboard water maker comes close. The feedwater
problem is that water contains suspended and dissolved feedwater solids. Pure water freezes first, leaving the feedwater solids
to increase in concentration in the unfrozen feedwater. Solids also bond to the evaporator wall during feedwater freezing,
forming scale. Eventually, built-up scale will shorten machine life.
A Dometic-supplied filter for use with ice makers must always be used, otherwise the warranty will be void. Replace the filter at
least twice yearly, or more often if the machine is used frequently. While filters help clean the water, a 6-month cleaning of the
evaporator barrel is required. See "Evaporator Cleaning" on page 21 of the "OWNER MAINTENANCE" section.
Using saltwater to make ice is not approved by Dometic. Saltwater is very corrosive, and it contains many more dissolved and
suspended solids than freshwater. If you want a brine solution for your catch, we suggest sprinkling salt over the ice in the
storage box. USE OF SALTWATER AS FEEDWATER IN ANY DOMETIC ICE MAKER WILL CAUSE SEVERE DAMAGE AND
VOID THE WARRANTY!

NSTALLING THE
Self-Draining System
A poorly plumbed seawater system is the most common installation problem. When water flow is lost, not only will the ice maker
cease to produce ice, but the pump could be damaged from running without water flow.
When using a centrifugal seawater pump, it is imperative that the seawater piping be routed continually uphill from the thru-hull
to the condenser, then smoothly up or down to the overboard discharge without any dips or loops, and with only one high point
in the system. This type of routing is called self-draining because all water will drain out of the piping if the boat is taken out of
the water.
If air gets into the system, which can happen in heavy seas or with a sharp turn, it can become trapped in the pump. Because
centrifugal pumps cannot pump air, water flow is lost. A self-draining system, however, allows air in the piping to rise naturally
through the pump and be expelled. It also makes winterizing the system much easier. Figure 7, page 10 shows a properly
plumbed system and some common mistakes.
