WRSC-6 Wastewater Removal System Kits
OWNER'S MANUAL
English
EN
Wastewater Removal System Kits 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 1/8” diameter, but large amounts of solids
can clog screen and result in pump failure.
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. See pump manual for more
information.
This product is covered by a Limited Warranty for a period of
12 months from the date of original purchase by the
consumer. For complete warranty information, refer to www.LittleGiant.com
