6. Connection of Pump-out Hose:
The pump-out hose is a 50’ section of 3/4” garden hose.
•Remove the cap from the pump-out outlet fitting on the back of the machine.
•Connect the pump-out hose to the outlet fitting.
•Place the other end of the hose in a commode or drain connected to the sanitary sewer system.
•Secure hose end to prevent movement during pumping.
Use defoamer to prevent foam build-up in recovery tank during cleaning and to keep foam/moisture from entering vacuums.
When ready to begin cleaning, turn the waste pump switch to the ON position.
•Do not turn on waste pump switch unless pump-out hose is connected and has been routed to a proper drain.

Connect the Female Garden Hose Fitting end of the Pump-out Hose to the outlet fitting on the back of the recovery tank. Place the other end of the pump-out hose in a sanitary drain.
If not using the waste pump-out, the pump-out hose does not need to be connected. When the recovery tank fills during cleaning, the float ball assembly in the vacuum inlet filter will rise and will automatically shut off the vacuum air flow to prevent the recovery tank from overfilling and waste water from getting into the vacuums. When this occurs:
•Immediately shut off the vacuum switches.
•Drain the recovery tank.
oTurn off the pump switch while draining the tank.
oTurn pump switch back upon resumption of cleaning.
•Close the drain valve and turn the vacuum switches back on when ready to resume cleaning.
If the pump-out or vacuum shutoff is not working properly, refer to the trouble shooting guide or contact your distributor for advice or assistance.
