3. Package Contents
Verify that all components are present before beginning installation:
- Johnson Pump Viking Power 16 Waste Pump, Single Diaphragm
- 1-inch hose connectors

4. Setup and Installation
The Viking Power 16 pump offers flexible installation options due to its ability to be configured in several pump/motor orientations. It can be installed anywhere after the drain outlet in a wastewater system or as a bilge pump.
- Mounting Location: Choose a stable, accessible location for mounting the pump. The pump's muffled rubber bracket helps reduce operational noise.
- Orientation Adjustment: The pump housing can be rotated to adapt to existing hose setups. To adjust, remove the two bolts securing the housing, rotate the housing to the desired orientation, and re-install the two bolts securely.
- Hose Connections: Connect the appropriate hose sizes (1-inch or 3/4-inch) using the provided connectors. Ensure all connections are tight to prevent leaks. The pump is also supplied with 1/2-inch BSP XL connectors.
- Electrical Connection: Connect the pump to a 12V power source. The pump features a 2.3 Amp motor with built-in thermal protection. Ensure correct polarity and use appropriate gauge wiring for the distance to the power source.
- Testing: After installation, test the pump by introducing water into the system to verify proper operation and check for any leaks.
5. Operation
The Viking Power 16 is designed for straightforward operation:
- Self-Priming: The pump is self-priming up to 3 meters (9.8 ft), meaning it can draw water without needing to be pre-filled.
- Air/Water Mixture: It can handle a mixture of air and water without difficulty, making it effective in various conditions.
- Run Dry Capability: The pump can run dry without sustaining damage, offering flexibility in operation.
- Quiet Operation: The low pulse design and muffled rubber bracket contribute to quiet operation.
6. Maintenance
The Viking Power 16 is engineered for easy maintenance to ensure long-term performance.
- Diaphragm Replacement: The premium-grade reinforced nitrile rubber diaphragm is designed for durability. When replacement is necessary, a spare diaphragm can be installed without removing the entire pump from the system. Refer to the service manual for detailed instructions on diaphragm replacement.
- Inspection: Periodically inspect hoses, connections, and electrical wiring for wear, damage, or leaks.
- Cleaning: While non-choke valves reduce the need for in-line filters, occasional inspection and cleaning of the pump's interior may be beneficial depending on the type of waste water being pumped.
7. Troubleshooting
If the pump is not operating as expected, consider the following common issues:
- Pump not running: Check electrical connections, fuse, and ensure the 12V power supply is active. Verify the motor is not overheated (thermal protection may have activated).
- Pump running but not pumping water: Ensure the pump is properly primed (it is self-priming, but severe air locks or dry running for extended periods might require manual assistance). Check for blockages in the inlet or outlet hoses. Verify that the non-choke valves are clear.
- Reduced flow: Inspect for partial blockages in hoses or valves. Check for air leaks in the suction line.
- Excessive noise or vibration: Ensure the pump is securely mounted. Check for foreign objects in the pump chamber or worn diaphragm/valves.
For persistent issues, contact customer support.
