6. Optional Auto Pump-out System - 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.
6A. Waste Tank Shutoff:
If not equipped with an Auto Pump-out System or 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.
o
Turn off the pump switch while draining the tank.
o
Turn 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.
