RECOVERY SYSTEM
VACUUM / RECOVERY SYSTEM SERVICE MAINTENANCE CHECKLIST
Whenever there is a vacuum problem, it’s best to check over the entire system. Use the checklist below as a guide, to thoroughly check
the vacuum system.
Clean built-up dirt from the inside of the squeegee tool.
Replace the squeegee blades if they are nicked or torn.
Inspect the hose between the squeegee tool and the recovery tank, rinse any built-up dirt from the hose. Replace the hose
if it is kinked or damaged.
Inspect and make sure the gasket on the recovery tank cover is sealing and not damaged.
Inspect and clean the vacuum motor filter and shut off float cage.
Make sure that the recovery tank drain valve seals airtight.
TROUBLESHOOTING GUIDE
If water flows around the ends of the squeegee tool, instead of being pulled into the tool, the vacuum system is not working properly.
When a vacuum system performs poorly, it is usually because of one of the following problems:
Vacuum Leak(s)
– Air flowing into the vacuum system past a bad gasket or leaky hose, damaged tank, or a leaky drain valve. A vacuum
leak below the water line will create turbulence in the recovery tank, causing water to enter the vacuum filter and motor.
Restriction(s)
– Anything that blocks the flow of air through the system. Restrictions may also be caused by built-up debris in the
squeegee tool, vacuum hoses, float cage or wherever the airflow is forced to make a sharp turn.
Both leaks and restrictions decrease the quantity of air flowing through the squeegee tool. The air that does go through the squeegee
tool moves slower, so it has less pick-up power.
