4.7 Connection of Vacuum Hoses
There are three (3) components used to connect the cleaning tool to the vacuums and
recovery tank:
1. 4-Foot Vacuum Hose: connected to the vacuum barb on the front of the
machine and to the outlet side of the clear view in-line filter.
2. Clear View In-Line Filter
3. 25-Foot Vacuum Hose: the 2” cuff on the 25-foot vacuum hose is
connected to the inlet side of the clear view in-line filter The other end with
the 1-1/2” cuff is connected to the cleaning tool.
When ready to being cleaning, turn both vacuum switches to the ON position. While
the machine can operate with only one (1) vacuum for cleaning delicate fabrics, in
most situations you will turn both vacuums switches to ON.

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.

4.8 Connection of the Auto-Dump Hose Continued
Use defoamer to prevent foam build-up in the recovery tank during cleaning
and to keep foam/moisture from entering vacuums.
When ready to being cleaning, turn the waste pump switch to the ON position.
DO NOT turn on the waste pump switch unless the auto-dump hose is
connected and has been routed to a proper drain.
Connect the female garden hose
fitting end of the auto-dump hose
to the outlet fitting on the back of
the recovery tank. Place the other
end of the hose in a sanitary drain.
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 of your machine’s operating manual or contact your
distributor for advice or assistance.
