Page: 6 / 56

DANGER: This product is not intended for damage control or to deal with flooding result-
ing from hull damage. This product is intended to be used in Bilge Pumping Systems for small
craft with a hull length up to 24 meters, as described within the introduction and scope of ISO
15083. Bilge Pumping Systems, as specified in ISO 15083, are limited to normal amounts of
water in an intact boat due to spray, rain, seepage, spillage, and occasional small amounts of
water shipped from boat movements in heavy weather. Use of product in any other way could
result in flooding, catastrophic damage to craft, serious personal injury, or death.
WARNING: This pump is designed for use with fresh water and salt water ONLY. Use with
any other hazardous, caustic, or corrosive material could result in damage to the pump and
the surrounding environment, possible exposure to hazardous substances and injury.
WARNING:
Check the function of all bilge pumps at regular intervals. Clear pump
inlets from debris. If seacocks are fitted in the fore and aft peak bulkheads, they shall be
kept closed and shall only be opened to let water drain into the main bilges.
RuleMate Intelligence
RuleMate Bilge pumps have built-in programming that can sense when the pump is running but
not pumping water to protect the pump, vessel, and the vessel’s batteries. If debris fouls the sensor
or the pump becomes air-bound, the pump will stop running and begin to “check” for water every
2 ½ minutes. Once the debris is removed, the pump will revert to its normal operation, turning on
when the water reaches approximately 2 ½” and shutting off at 5/8”.
Our Rule-Mate bilge pumps contain a fail-safe back-up program that measures the amount of
work the motor is performing and the length of time the motor is running. If debris, such as
a wet paper towel or leaves, became lodged against the pump, it could “trick” the pump into
thinking water remained in the bilge which could deplete the vessel’s battery.
If the circuit board senses the motor is running but doing little work (not pumping water) for
longer than fifteen seconds, the pump will enter into a cycling mode in the same fashion as the
computerized pumps. The pump will sense water every 2.5 minutes and if it senses water, it will
continue to run until the water has been removed from the bilge.
After the debris is removed, the pump will automatically revert to the level sensing mode.
