Vacuum System

The extractor uses a dual-vacuum motor system that provides outstanding water lift and
airflow.
Vacuum Float Assembly Warning System:
The float assembly shut-off, located in the recovery tank on the vacuum stand pipe,
prevents the waste tank from overflowing into the stand pipe and damaging the vacuum
motor. The float assembly will cut off vacuum to the waste tank. The motor will also
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 motor and empty the waste
tank. If the operator continues to use machine after the tank is full, it will VOID the
Warranty.
The float assembly has a filter to prevent debris from entering the stand pipe. Refer to
the "Maintenance" section for removal and proper cleaning. It is also necessary to use
low-foaming chemicals or a defoamer to eliminate foam buildup in the recovery tank and
damage to the vacuum motors.
If moisture enters the vacuum motors, contact an authorized service center. To prevent
moisture from damaging the vacuum motors during storage, empty the recovery tank and
store with the lid open.
4.3 Power Priming the High-Pressure Pump
Once water is in the solution tank, the high-pressure pump
must be primed:
• Turn ON both vacuums then the solution pump. The
vacuum will pull solution through the pump and prime
valve into the vacuum tank.
• Place the end of priming hose inside the vacuum hose barb.
• Cup a hand around the hose and barb to increase the
vacuum suction on the hose. When the pump is primed, you
will hear the pulsation of the pump change.
• After priming, turn OFF the solution pump. If you have not
yet connected your solution hose or tool, you may have to
relieve the pressure in the line so you can connected your
hose or tool.
If the pump still does not prime or if flow is low or unsteady, check the hose from the
solution tank to the pump (as well as the filter) for clogging, kinks, or restrictions. Clean
or replace hose and/or filter and repeat the priming process.
If you are having trouble with the pump, refer to the "Troubleshooting Guide" section or
contact Jon-Don for advice or assistance.
