OPERATING INSTRUCTIONS
IMPORTANT! This pump is made out of polypropylene, PVDF, PTFE, 304 stainless steel and EPDM. Use chemicals compatible with these materials and follow OSHA guidelines when using this pump, including proper grounding and protective gear as required. Unit not UL or FM approved.
- Rotate handle clockwise several times to prime. If unit does not prime after a few turns, pouring some fluid into pump inlet may help free pump.
- For siphoning, position handle straight down.
- To stop siphoning, rotate handle 1/4 turn (leave handle in horizontal position).
- After using pump, position handle straight down. Liquid will drain back into the container.
- If pump is removed from drum, rinse it thoroughly in a liquid that is compatible with both the pump and the fluid being pumped.
- Regularly check pump and suction tubes for leaks. Leaks in the suction line or in pump housing will cause inefficient pumping and loss of prime.
