Use defoamer to prevent foam build-up in recovery tank during cleaning and to keepfoam/moisture from entering vacuums. Use Hydro Filter II inline filter to trap and remove debris from the waste water before itenters the recovery tank. Excess debris in recovery tank may clog Pump-Out filter. CleanFilter as needed during use. Do not turn the Waste Pump switch ON unless pump-out hose is connected and has beenrouted to a proper drain. The Waste Pump does not use a float switch and will run as soon as the Waste Pump switchis turned ON. It is made to run continuously while cleaning, as this type diaphragm pumpcan run dry without damage.When ready to begin cleaning, turn the Waste Pump switch to the ON position.If not using the waste pump-out, the pump-out hose does not need to be connected.
