Fishbox Pump
The 320 CC is equipped with a diaphragm pump called the gulper grouper (pictured to
the right). The Whale Gulper Grouper pump has no impeller to clog or burn out. Unlike
impeller pumps these have no-choke valves that easily pump out sh box waste.
They also offer long term durability, they can run dry without causing damage.
Troubleshooting
• Electric Motor Runs but doesn’t pump
• Disconnect pump and turn off all power.
• Disconnect hoses and unscrew housings.
• Check entire hose system for blockage.
• Inspect tricuspid valves for blockage or inverted valve(s).
• If valve(s) are blocked, remove blockage, re-assemble the pump and continue
use.
• If a tricuspid valve is inverted, replace with a new tricuspid valve, reassemble
the pump and continue use.
If the electric motor will not operate, check that:
• The isolator switch is on.
• There is 12 volts at the battery terminals.
• The in-line fuse / circuit breaker are operational.
If the fuse / circuit breaker has blown, check for debris in pump head and clean out
if necessary. Replace the fuse or re-set circuit breaker and run the pump.
