Vacuum System

The extractor uses a dual vacuum motor system that provides outstanding water lift and air flow.
Vacuum Float Assembly Warning System:
overflowing the stand pipe and damaging the vacuum motors. Motors will reach a fast, high-pitched sound alerting you
when the recovery tank is about to over flow. When this happens, immediately turn OFF the vacuum switches and empty
the waste tank.
The float assembly has a filter to prevent lint and debris from entering the stand pipe. Refer to the "Maintenance" section
for removal and proper cleaning.
An optional in-line filter (OE-ILF-EA) can be purchased and is recommended for use with all jobs.
Recovery Tank:
It is also necessary to use a defoamer to eliminate foam build-up in the recovery tank which could lead to foam/moisture
entering the vacuums and contributing to early failure of the vacuum motors.
If moisture does enter the vacuum motors, contact your local Jon-Don service center. To prevent moisture from damaging
the vacuum motors during storage, empty the recovery tank and store with the lid open.

4.0 Shutdown Procedures

• If using the auto-fill system, turn the water supply OFF before finishing each job. This will allow use of the water and
chemicals already in the tank and will reduce the amount of excess water to be disposed of later.
• When finished cleaning, turn OFF all switches.
• If the auto-fill system was used and there is still water in the solution tank, push the float down to release the water
inlet hose pressure before disconnecting the hose from the faucet. Disconnect the
water inlet hose from the quick disconnect on the front of the machine.
• Disconnect the solution hose and vacuum hose from the cleaning tool. Pull the
valve trigger to release pressure from the hose before disconnecting the solution
hose from the cleaning tool.
• Disconnect the clear view in-line filter from the vacuum hoses and clean the filter
as needed.
• Disconnect the vacuum hose and solution hose from the machine.
• If water remains in the solution tank, use the short vacuum hose and vacuum the
excess water from the tank.
• If the auto-fill system was utilized, place the chemical feed hose back into the
solution tank.
• If the dump-out system was used: turn the waste pump switch ON to pump
out any remaining water from the recovery tank; turn switch OFF, remove the
dump pump-out hose from the outlet fitting and replace the cap; roll up the hose
toward drain to remove the remaining water from the hose; connect ends of hose
together to prevent dirty water from dripping from hose during transport.
• Disconnect the power cords from the outlets and from the machine.
• Remove the float assembly from the recovery tank and clean filter as needed.
Replace float assembly and tank lid.
• Drain any remaining water from the recovery
tank and dispose of in a sanitary drain. DO NOT use the same bucket to drain the
tank that you used to fill the tank.
• Roll up all hoses and tools. Collect and store extractor, all tools and accessories.
