Every precaution has been taken in the preparation of this manual to insure its accuracy. [. . . ] 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. Do not use pump connections to determine hose 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. Some strainers have an arrow that shows correct flow 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. The pump should be accessible for future service. Mount the pump so the outlet is directed upward. 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. Run appropriate seawater piping from the strainer to the pump, and use Teflon tape or equivalent on pipe threads. 2. Figure 4: Dometic Pump Head Orientation Correct Orientations Incorrect Orientations Self-Priming Pumps Self-priming pumps are available if a centrifugal pump cannot be mounted below the waterline. Manifolds If a pump serves multiple units, a seawater manifold is needed to supply water to all units. This can be as simple as a tee for two units, or a custom manifold for seven to eight units. It is very important to consider manifold orientation so that all units get their required flow. See Figure 5 below for proper orientation tips. Verify the manifold still provides the required flow rate for the ice maker. A manifold can also be used on the outlets of multiple ice makers when using a single overboard discharge. 8 L-2448A ENGLISH Eskimo Ice Installation Manual - Self-Contained System INSTALLATION PROCEDURES Figure 5: Seawater Manifold Orientation Pump Relay The pump relay (if needed) is generally located in the engine room or mechanical space near the seawater pump, but can be mounted anywhere that is convenient and accessible. It must be in a dry location, away from water spray, with some room for heat dissipation. Choose your pump relay based on the number of units that will operate off one pump. [. . . ] Set per instructions in "Setting the CPV" on page 13. If under warranty, call for authorization before adjusting CPV, otherwise warranty will be voided. Check for obstruction at the ice discharge in the ice storage bin. Check routing for dips or kinks in the ice-delivery hose. [. . . ]
