This Whale® Electric Field Sensor senses water level and automatically controls a 12 or 24 volt bilge pump. The switch
turns on when it senses 51mm (2") water level and turns off when water is below 13mm (1/2"). This product is designed
for use in pleasure boat applications, and is not intended to be used for commercial boating applications or any other use.
1. Not suitable for use with flammable liquids, diesel, chemicals etc.
2. Suitable for only freshwater or bilge water. If it is intended for any other purpose or with any other liquid,
it is the users responsibility to ensure that the switch is suitable for the intended use and, in particular,
that the materials are fully compatible with the liquids to be used.
3. Failure to fuse and connect wires according to these instructions will void product warranty and may cause damage
or serious injury.
4. Connect in-line fuse (Note: Fit the appropriate amperage specified for your pump model).
5. Correct voltage range is 10.5 V d.c. to 28.8 V d.c. DO NOT use with other voltage, with A.C., or A.C.to D.C.
converted power sources.
6. The Electric Field Sensor may draw up to a maximum of 20 amps.
7. NOTE - Maximum operating temperature ~ 60°. Maximum flash temperature ~ 90°
7.1 Location
1. Mount the switch vertically as shown in fig. 1 (wires located uppermost). Locate the switch as close to the pump
as possible to ensure the same water level.
2. Prepare a mounting block. Do not fasten switch directly to the hull. Mounting block should be minimum 10mm
(3/8") thick marine plywood epoxied to the hull.
3. Switch base may be located up to 6mm (1/4")
higher, but NEVER located lower than base of
the pump.
7.2 Mounting
1. Use switch base (Fig. 1) or mounting ears (Fig.
2) as a template to mark pilot holes in mounting
block.
2. Set drill depth gauge to avoid drilling through
hull. Drill two 3mm (1/8") diameter pilot holes.
3. Fasten switch onto mounting block with #8 x
1/2" (3.5mm diameter x 13mm) stainless steel
screws (not supplied).
