Location and Sump Requirements
- The pump must be installed in a properly sized and vented sump or basin.
- Ensure the sump is free of debris before placing the pump.
- The pump should be placed on a solid, level surface at the bottom of the sump.
Piping Connections
- Connect the discharge piping to the pump's outlet. Ensure all connections are watertight.
- Install a check valve in the discharge line to prevent backflow.
- A shut-off valve is recommended for ease of maintenance.
Electrical Connections
- The pump requires a 115V, 60 Hz, single-phase power supply.
- Connect the pump to a dedicated, properly grounded circuit with appropriate overcurrent protection.
- Ensure the float switch is installed and adjusted correctly to control pump cycles.
Operating Instructions
Once installed and connected, the Zoeller Shark Model 807-0001 operates automatically via its float switch.
Initial Start-up
- Ensure all piping and electrical connections are secure.
- Slowly fill the sump with water to activate the float switch.
- Observe the pump for proper operation: it should turn on, pump down the water, and then turn off.
- Check for any leaks in the discharge piping.
Normal Operation
The pump will activate when the water level rises to the "on" level set by the float switch and will continue to run until the water level drops to the "off" level. The grinding mechanism processes solids before pumping.
