More details

  • WATER WITCH

Request information >
WW101/12
WW101/24
15 A / 12 Volt 10 A / 24 Volt

ELECTRONIC = Debris in the bilge will not damage the Water Witch
INSIGNIFICANT CONSUMPTION = 0,004 Amp (at rest)
SWITCH ON DELAYED of 6/8 seconds = Prevent pump cycling due to sloshing
SWITCH OFF DELAYED of 14/16 seconds = Complete pump off
STAINLESS STEEL SENSORS = No problems due to scums or foams
COMPACT SIZE = Easy mounting even in restricted locations
OVER 19 YEARS OF EXPERIENCE = The Advantage of the First

By means of an electronic circuit, the WATER WITCH activates the bilge pump when the water wets the sensors for no less than 6/8 seconds. The delay avoids pump stutter and once water has left the sensor, the switch continues to run the pump far additional 14 seconds to clear the output hose.


ASSEMBLY
WATER WITCH  lower sensor must be installed about 3 cm above the normal water level with wires coming out from top.

Check that the connections with the pump and the battery are well over the level water can reach.
The pictures show two possible mounting of the model 101 Water Witch.

ELECTRICAL CONNECTIONS

  1. Disconnect the battery.
  2. Select a mounting location for the Water Witch; the water sensor, the lower sensor furthest from the wires, should be above the standing water level.
  3. Always keep the wire connections above the highest water line.
  4. Connect the wires in the following order following the wiring diagram below:
  5. From the Water Witch connect the Tan to the Positive (+) side of the pump or device being controlled, connect the Black to the Ground or the Negative (-) side of the battery and connect the Red to the Positive (+) side of the battery through a fuse.
  6. Reconnect the battery and the pump will run several seconds while the switch self-calibrates.
  7. WHENEVER POWERS IS APPLIED, THE SWITCH RUNS THE PUMP FOR SEVERAL SECONDS TO SELFCALIBRATE.
  8. To test, apply a wet rag across the two sensors on the front of the unit.
