Eskimo Ice Installation & Operation Manual INSTALLATION PROCEDURES
L-3152 ENGLISH 11
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”.
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.
1. Mount the strainer to a bulkhead so it is properly supported before connecting hoses.
2. Make sure the water flow through the strainer is in the correct direction. Some strainers have an arrow that shows
correct flow direction.
3. Run appropriate seawater piping from the seacock to the strainer, and use threaded-seal tape on pipe threads.
Seawater Pump
Required Flow Rate
The Dometic EI1000D ice maker requires at least 3.3 GPM up to a maximum of 4.4 GPM of seawater flow for rated
performance.
Centrifugal Pumps
Figure 8: Dometic Pump Head Orientation
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.
1. 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 8, and the head on these
pumps can be rotated to allow mounting on a vertical
bulkhead.
2. Run appropriate seawater piping from the strainer to the
pump, and use threaded-seal tape on pipe threads.
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 9 on page 12 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.
