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.
□ Inspect and clean the vacuum motor fl oat switch. (If the switch is open [tipped up] the vacuum motor will not operate)
□ 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 and 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.
□ Make sure that the recovery tank drain hose cap seals airtight.
TROUBLESHOOTING GUIDE
If water fl ows 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 fl owing 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 motor.
Restriction(s) – Anything that blocks the fl ow of air through the system. Restrictions may also be caused by built-up debris in the squeegee tool, vacuum hoses,
and vacuum motor inlet screen or wherever the airfl ow is forced to make a sharp turn.
Both leaks and restrictions decrease the quantity of air fl owing through the squeegee tool. The air that does go through the squeegee tool moves slower, so it has
less suction (water lift performance).
