9.4 Electrical Wiring
Ensure all wire connections are at the highest level above water. Use marine grade wire connectors
only and 16 AWG tinned copper wire. Waterproof all connections with suitable materials (see figures
4 and 5).
• Connect positive (+) brown wire (500, 950 and 1300) or red wire (2000 and 3000) to
switch. For automatic operation, use an Automatic Float Switch (Whale BE9003).
• Connect negative (-) black wire to ground.
• Install fuse holder within 72" (183cm) of the positive (+) battery terminal.
• To test system, feed water into the pump. If flow rate appears low, make sure wires are
connected properly:
Brown or Red to switch Black to negative (battery)
WARNING: Reversed wiring reduces performance and can cause pump failure.
WARNING: Fire hazard. Wiring must comply with applicable electrical standards and include
a properly rated fuse or circuit breaker. Improper wiring can cause a fire resulting in injury or death.
NOTE Switch off the power prior to making connections. Suggested wiring information is given as a
guide only. For full information, refer to the USCG, ABYC and ISO regulations for marine applications
and wiring gauges, connectors and fuse protection.
This Orca is designed only to require minimal maintenance.
WARNING - Before servicing, disconnect power to the pump and drain system.
Optimal performance
• Regularly remove motor housing and inspect and clean the filter to be sure that it is not
being blocked by debris.
Annual Checks
• Whale advise that the boat’s plumbing system should be checked at least annually for
leaks and obstructions. Also a pump electrics test is advisable. If you are not familiar
with applicable electrical standards, ensure that the electric test is completed by a
qualified electrician/ technician
NOTE - Fully drain the system for winterizing
Whale do not guarantee warranty if the system is not fully drained for winterizing.
