[. . . ] 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 7 shows a properly plumbed system and some common mistakes. 6 L-2448A ENGLISH Eskimo Ice Installation Manual - Self-Contained System INSTALLATION PROCEDURES 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). Make sure enough hose is used to allow for future removal of components. Use the correct size hose, fittings, and components: 5/8" seawater hose, 3/4" inlet. Note that the pump inlet piping (including thru-hull and strainer) may need to be larger than the outlet pipe size. The "pump inlet" recommended pipe size includes all fittings and hose up to the pump connection (thru-hull, seacock, strainer, hose, manifold). The "pump discharge" recommended pipe size includes all fittings and hose from the pump discharge up to the overboard discharge, and should be a minimum of 5/8". 7 Seawater Piping · L-2448A ENGLISH INSTALLATION PROCEDURES Eskimo Ice Installation Manual - Self-Contained System Strainer A seawater strainer must be installed between the seacock and the pump, and should be situated to provide easy access for cleaning. The strainer must be located vertically above the seacock and below the pump so any air that gets into the strainer can get out. Mount the strainer to a bulkhead so it is properly supported before connecting hoses. Make sure the water flow through the strainer is in the correct direction. Run appropriate seawater piping from the seacock to the strainer, and use Teflon tape or equivalent on pipe threads. Seawater Pump Required Flow Rate The Dometic EI600D ice maker requires 2. 5 GPM (150 GPH) and the EI250D requires 1. 25 GPM (75 GPH) of seawater flow for rated performance. Centrifugal Pumps Centrifugal pumps are not self-priming, and must be mounted so they are below the heeled waterline in any given operating condition. If you are using the Dometic pump, other mounting orientations are acceptable as shown in Figure 4 below, and the head on these pumps can be rotated to allow mounting on a vertical bulkhead. [. . . ] 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. [. . . ]
