INSTALLATION & OPERATION
- Insert handle into fulcrum, making sure that fulcrum and handle holes align before inserting the fulcrum pin.
- Place pump on a solid foundation that is as close as possible to the fluid that is going to be pumped. (This positioning should make the suction line as short and direct as possible.)
- Attach suction pipes to the suction inlet and to the discharge outlet.
- Suction line must be sloped upward in order to provide continual feed into the pump.
-
SAFETY & RECOMMENDATIONS
- To extend diaphragm and valve life, flush the pump with water after each use.
- Replace the diaphragm and valves that show signs of wear, cracking or corrosion.
-
Troubleshooting
If you cannot get the HP to prime, try one of the following: - Make sure there is no debris left inside where the valves are. Any debris can cause clogging.
- Inspect the diaphragm for any tears or cracks.
- Check the line for any blockage or loops. The line must be straight and not twisted in any way.
- Check any strainers for blockage.
- Check all sections of the suction line for air leaks.
- If the eyebolt assembly becomes loose from the diaphragm assembly:
- Remove the bolts which connect the retainer ring and pump body so that the diaphragm assembly can be removed.
- Remove the diaphragm assembly and tighten the jam nut located on the underside of the diaphragm assembly until the bottom jam nut is even with the bottom of the eyebolt.
- Re-assemble the pump by reversing the dis-assembling process. *When re-assembling the pump, have the pump’s discharge side to your left, and make sure that the opening of the eyebolt is facing you.
