WRS-5 Wastewater Removal System Kits OWNER'S MANUAL English

Wastewater Removal System Kits (WRS-5) are designed to pump wastewater from laundry trays, washing machines, sinks, or dehumidifiers. They are not designed to pump raw sewage, fluids other than water, or fluids with solids. An inlet screen will remove many solids over ⅛-inch diameter, but large amounts of solids can clog the screen and result in pump failure. See pump manual for more information.Maximum fluid temperature is 125 °F. The unit is designed to fit under most sinks, so in many cases it is not necessary to recess the unit into the floor.This product is covered by a Limited Warranty for a period of 1year from the date of original purchase by the consumer.
