Fluids
Not for use with gasoline.
Compatible for diesel, oil, or water.
Installation
Considerations when mounting the pump:
• Provide accessibility to the cover plate of the pump for future impeller changes.
• Mounted in any orientation on a vertical or at surface, however Reverso does not recommend mounting with the
pump head above the motor.
1/2” ID Minimum of 1/2” inner diameter hose is recommended; smaller hose is not advised.
Choose ttings which t the hose size selected to minimize restriction.
Use Loctite 565 on all connections.
Electrical Connection
The electrical installation of this product must be executed by a qualied electrician and following the ABYC requirements.
Be sure that the power source available matches the power requirements on the specication sheet.
Operation
The pump is equipped with a 3-position rocker switch. The center position is Off.
To start the pump, press the arrow for the desired ow direction.
Return switch to the center Off position after required amount of uid has been transferred.
Avoid running the pump dry for long periods.
• Check for a blown fuse.
• Check inside the pump head for any debris or broken blades on the impeller.
• Verify the voltage supplied matches the specications of the pump motor.
• Check for restrictions in the hose or tting size.
• Check for air leaks in the lines or seals.
• Check if impeller has dried out due to a long period without use. If yes, add uid into
pump head before startup.
