File around the fitting inside diameter to remove burrs and rough edges. Figure 1 Deluxe Shower Sump System 4137, 4138 Mounting Instructions Attwood marine hardware, navigational lighting, bilge pumps, and other marine accessories are specified more than any other brand by America’s best-known boat manufacturers as original equipment. Look to Attwood for quality replacement parts and marine accessories. SAVE THESE INSTRUCTIONS Form Number 69274 Rev. K 98-08 The Attwood Deluxe Shower Sump System is an efficient, low cost system incorporating an Attwood 750 GPH Pump and an Attwood Automatic Float Switch. This system is designed to satisfy the needs of the boater for a functional means of transferring “gray” water from the shower, or other water drains. Multiple inlets can be hooked up to more than one drain with different hose size options. The see-through top on the box allows you to see when the filter needs cleaning. Refer to the chart below to ensure that you have selected the proper shower sump for your boat application: Shower Sump D.C. Voltage D.C. Amps Max Fuse Model Amperages 4137 12.0 2.7 4 4138 24.0 1.8 2 WARNING: To prevent personal injury, never use 120/240 VAC power tools while working in water or a wet environment. To prevent personal injury, always disconnect the power source before servicing or installing this product. Always use the fuse amperage rating specified for this shower sump model. Failure to do so could result in serious personal injury or fire hazards. To prevent possible injury and water damage, shut off all water before servicing. REQUIRED FOR INSTALLATION • Fine-tooth hacksaw or • Phillips screwdriver band saw • One hose clamp for each • File hose used • Drill and suitable drill bit • Wire connectors for 16-gauge wire • Four #8 screws for hold-down clamps • See amperage in chart above Optional: • Attwood model 7615 switch or equivalent Note: Switch is recommended to allow the pump to be turned off in an emergency The following materials are needed if no sump pump mounting pad is in place: • 1/2" (1.27) thick marine plywood • Fiberglass—18 oz. mat or woven block large enough to mount roving sump pump • Polyester resin and catalyst • Hand-held roller INSTALLATION INSTRUCTIONS 1. Determine location of sump system, making sure system is lower than the shower drain. Ensure there is enough structure and room to accommodate the sump system before drilling. Note: For correct operation of the automatic float switch, the box should be mounted level. If the box cannot be mounted level, the end without fittings can be raised up to 1/2" from level. Note: Because sailboats tend to heel, install sump system parallel lengthwise with the bow-to-stern line. Fitting end can face either fore or aft. Cover Optional 1/4" Vent Hole Location Float Switch FilterPump Box Inlets Outlet • • • • • • • • • Figure 1 3. To install mounting pad: Locate mounting pad area according to guidelines in Step 1. 4. Sand gelcoat or paint off the mounting surface to create an area that is 3" wider than the mounting pad on each side. Completely cover the mounting pad with fiberglass. Saturate the fiberglass with resin, and press the fiberglass edges down against the hull to adhere the pad in place. Roll out the fiberglass to remove any uneven surfaces, air bubbles, or excess resin. 5. Place the box in desired location. Position the hold-down clamps (two on each side) so the top of the clamps are between the two raised ribs. Figure 2 Mark the screw hole locations and drill the pilot holes. Do not drill through the hull! Note: If possible, pre-wire the sump system before fastening clamps down. See wiring diagram. Figure 4 Figure 2 • • Hold-Down Clamps 6. Connect 3/4" I.D. outlet hose from thru-hull connector to the outlet fitting. Secure the connection with a hose clamp. Note: The outlet hose must rise smoothly from the fitting, up to the thru-hull. Any downward dip will trap water and air inside the pump. Figure 3 Figure 3 For correct operation, outlet hose must continually rise above pump outlet to prevent air-lock • Inlet Hose(s) • Outlet Hose • Hose Clamp 7. Connect inlet hoses from the drains to the inlet fittings. Secure each connection with a hose clamp. Note: The inlet hoses must rise smoothly from the fitting, up to their Drains. Also, using a shower drain with a trap will not allow air to vent out of the box, and the rising water will not activate the float switch. If the hose cannot be routed upward, or a drain with trap is desired: Vent the sump system box by removing the system cover and drilling a 1/ 4" hole where indicated. File away any rough edges, and replace the cover (position hole toward the box end with no fittings). See Figure 1 8. Fasten sump system in place with the four hold-down clamps and four screws.
