Installation and Operator's Manual
Water Smart®Switch:
The Water Smart® SCS Bilge Pump Switch is
designed for use as an electronic bilge pump switch in
boats. An upgrade from the original “Water Smart
Switch”, the SCS now features microprocessor
memory for constant self-calibration to adapt to any
environment for reliability. Installation of the Water
Smart Switch allows you to comply with State and
Federal regulations while reducing the risk of adverse
publicity, fines and expensive cleanup costs from a
large Oil Spill.
Model Description Volts Amps
WSS12 Water Smart SCS Bilge Pump Switch 12VDC 12A
WSS24 Water Smart SCS Bilge Pump Switch 24VDC 12A
Features:
• No Moving Parts. Patent Pending Electronic Water
Smart® Pump Switch
• Outlasts any other bilge pump switch through Self
Calibrating Sensor (SCS) technology.
• After each cycle, the switch recalibrates to its
original settings compensating for any
environmental changes.
• Environmentally Responsive: Prevents major oil
spills. Oil will not activate the switch
• Small enough switch to not overcrowd the bilge
and can be placed at any predetermined level.
• Incorporates a pump on level sense point, an
eight (8-10) second time delay allowing for
maximum water elimination as well as the
elimination of pump cycling for prolonged pump
life. Includes backup sensor with its own pump
down time-delay for ultimate “pump on”
protection
• Solid state circuitry - no moving parts
• Defined trip point-Oil/fuel spills will not activate
pump
• Performance is not hampered by accumulated oil
and grease
• Extended sensors allow the switch to be mounted
high above the contaminated water
• UL 508 Marine Listed "Electrical Industrial
Control Equipment" and NFPA 302
• UL Listed in accordance with ISO 8846-
Protection against ignition of surrounding
flammable gases
Water Smart Bilge Installation:
I. Disconnect voltage source, route and secure
all wires as high as possible above the water
level.
II. Mount switch in the vertical only, do not
mount horizontally on bottom of bilge.
Complete Mounting Hardware included.
III. Be sure the bottom of switch sensor (turn on
level) is aligned high enough above the
pump impeller (1 to 4 inches) for proper
turn off and turn on.
IV. For maximum efficiency of the eight (8-10)
second delay the switch should be placed
high enough that when the switch detects
water, the switch turns on and runs for 8-10
seconds after it no longer detects water. At
this time the water would be eliminated at
the same time the pump turns off.
V. If the switch is installed too low,the proper
dead span (amount of distance between on
and off) will not be achieved, the pump will
continue to run pumping any oil/fuel that
might be floating on the surface of water.
