To maintain grounding continuity when flushing or 
relieving pressure, always hold a metal part of the 
valve firmly to the side of a grounded metal pail, 
then trigger the valve. 

To ground the pump, remove the ground screw (Z) 
and insert through the eye of the ring terminal at end of 
the ground wire (Y). Fasten the ground screw back onto
