Whale Gulley IC SG8284 Shower Kit wiring diagram

SG8284 combines the 12 V Gulper IC BP2082B pump with a Gulley IC sensor and 4 m connection cable. It is not interchangeable with an ordinary Gulper 220 or 320 merely because those pumps look similar. The IC sensor starts the pump after water detection and the control provides a short run-on after draining. Use compatible Whale IC accessories and sealed factory connectors.

Connect red to protected positive and black to DC negative. The 12 V range is 10–13.6 V; retain the specified 10 A automotive fuse and use at least 1.5 mm² cable, increasing it for the route and voltage drop. The performance table gives 7.5–8 A at its stated heads; the catalog uses 8 A for that operating envelope and leaves startup current unknown. White is a combined running-indicator/manual-override interface: the diagram connects an indicator from white to negative or a momentary override from protected positive to white. It is not a load supply output with a published amp rating.

Put the gulley sensor at the shower outlet and connect its sealed Deutsch plug to the pump’s IC cable. Place the non-submersible pump dry and above standing bilge water. If mounted vertically, the head goes below the motor. Follow the 19/25 mm hose arrangement and avoid restrictions, kinks and unsupported joints. The listed maxima are 3 m suction, 3 m discharge and 4 m combined lift; do not add the first two into a supposed 6 m total.

Apply water at the gulley and observe the approximately one-second start delay. Confirm complete drainage and the approximately nine-second overrun, then check that the pump stops without repeated cycling. If fitted, test the optional indicator and momentary override separately. Persistent running calls for inspecting the sensor, trapped water and wiring. Isolate the circuit before disconnecting connectors or servicing the diaphragm. The standard example shows the supply to a complete kit; the signal markers do not reproduce its automatic timing.
