yy: 8 WARNING RISK OF ELECTRIC SHOCK This pump is supplied with a grounding conductor and grounding type attachment plug. NEVER REMOVE GROUND PIN FROM PLUG. To reduce the risk of electric shock, be certain that it is connected only to properly grounded, rounding-type receptacle. The national Electric Code requires that a ground fault interrupter circuit (GUCCI) be installed in every branch circuit supplying the fountain or pond equipment. Your dealer can supply Clog units. Do not immerse the plug in water.
