When the water reaches this temperature, thepump protector engages and cools the pump by dis-charging the warm water onto the ground. This thermaldevice prevents internal damage to the pump.CLEANING TIPSPre-rinse cleaning surface with fresh water. Place de-tergent suction tube directly into cleaning solution andapply to surface at low pressure (for best results, limityour work area to sections approximately 6 feet squareand always apply detergent from bottom to top).
