Connection of Auto-Dump Hose

The auto-dump hose is a 50-foot section of a 3/4" garden hose.
• Remove the cap from the auto-dump outlet fitting on the back of the machine.
• Connect the auto-dump hose to the outlet fitting.
• Place the other end of the hose in a commode or drain connected to a sanitary sewer
system.
• Secure the hose end to prevent movement during pumping.
Use defoamer to prevent foam build-up in the recovery tank during cleaning and to
keep foam/moisture from entering vacuums.
50-Foot Auto-Dump Hose
Part No. 80-0112
If not using the auto-dump feature, the auto-dump 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 from getting into the vacuums. When this occurs:
• Immediately turn OFF the vacuum switches.
• Drain the recovery tank. Turn OFF the pump switch while draining the tank. Turn
pump switch back ON upon resumption of cleaning.
• Close the dump valve and turn the vacuum switches back ON when ready to resume
cleaning.
If the auto-dump or vacuum shut-off is not working properly, refer to the "Trouble
Shooting Guide" section or contact your distributor for advice or assistance.
