Attwood 4201, 4202 - Automatic Float Switch Installation

SAVE THESE INSTRUCTIONS

This automatic float switch converts any standard bilge pump to automatic operation. Pump must operate on 6 to 32 volts D.C. (see chart). The switch can be mounted separately from the pump; it can also attach to the mounting bracket of any Attwood V-Series pump—4204, 4206, 4207, 4209, or 4212.

This product is not intended for use with AC voltage systems, including AC-to-DC converted power sources.

Always disconnect the power source when installing or servicing this product.

Always use the fuse amperage rating specified for your pump model.

Do not allow sealants containing acetic acid—such as silicone rubber—to come in contact with the switch housing. They can damage and crack the plastic, causing the switch to fail. Sealants with acetic acid smell like vinegar.

MOUNTING INSTRUCTIONS

1. Locate float switch as close as possible to the bilge pump. Switch should never be mounted at lower level than pump. Switch mounting surface should be at least level with the pump mounting surface, up to 1/4" (6mm) higher.
   If mounting with a V-Series pump, the front tabs on the switch may be interlocked with the rear slots on the pump bracket.
   Figure 1
   
2. With switch in desired mounting position, mark the two mounting holes.
3. Set depth gauge on drill bit to prevent drilling through hull.
   Drill a 1/8" (3mm) diameter pilot hole at each mark.
4. Align switch over pilot holes. Feed wires under test knob or out rear of switch. Fasten switch using #8 stainless steel screws. Be sure screws penetrate wood only; do not screw into the boat hull. Figure 1

WIRING INSTRUCTIONS

5. Wire float switch and bilge pump as shown in any one of the three diagrams.
   Figure 2
   
   Please note that in each case, float switch is in series (in-line) with pump and must be connected to the positive (+) battery terminal.
   The lead wires must terminate in a waterproof connection. Mount wires above the highest possible water mark. For extra protection, liberally coat butt joints and adjacent wire ends with liquid electrical tape.
   Failure to properly fuse and make the appropriate water-resistant connections will void the product warranty.

CARE AND MAINTENANCE INSTRUCTIONS

Periodically remove cover and clear away any debris that has accumulated around and under the float, around the float arms, and in the strainer slots.

Periodically check the electrical connections to ensure that they are waterproof and mounted high and dry.
