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. A filter must always be used, preferably one supplied by Dometic for use with ice makers. Replace the filter at least twice yearly, or more often if the machine is used frequently. While filters help clean the water, a yearly cleaning of the evaporator barrel is required. See "Evaporator Cleaning" on page 14 of the "OWNER MAINTENANCE" section. 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! INSTALLING THE SEAWATER COOLING SYSTEM 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. A self-draining system, however, allows air in the piping to rise naturally through the pump and be expelled. Figure 3, page 8 shows a properly plumbed system and some common mistakes. L-2448B ENGLISH 7 INSTALLATION PROCEDURES Eskimo Ice Installation Manual - Remote System Figure 3: Seawater Piping Recommendations Thru-Hull Inlet Fitting A separate thru-hull fitting must be installed for each seawater pump. Do not attempt to draw water from the thru-hull fitting of an engine, generator, or other device. Drill a properly sized hole for the thru-hull fitting as far below the water line and as close to the keel as possible. Bed the scoop with marine sealant designed for underwater use, and tighten the nut onto the thru-hull to secure it. Seacock The seacock must be accessible and easy to close in case of emergency or to clean the strainer. · · · · · · Install a full-flow seacock directly onto the thru-hull fitting. Only use reinforced marine-grade hose or other suitable piping (PVC, CPVC, cupronickel, or stainless steel). Use only plastic, bronze, or stainless steel fittings (do not use brass). [. . . ] Prepare cleaning solution: Mix 8 ounces (237ml) of Scotsman Ice Machine Cleaner, or equivalent, with two quarts (1. 9L) of hot water. Continue pouring cleaning solution into the reservoir, maintaining the level just below overflow, while the machine makes ice. Continue ice making until all the solution is used and the reservoir is empty. Let the machine make ice for AT LEAST 15 minutes to flush out any remaining cleaning solution. [. . . ]
