Maintenance of Recovery Tank Float Switch

See Figure 12. If the recovery tank float switch becomes dirty it can impair its operation. A dirty vacuum shutoff switch

can cause the vacuum motors to not function at all, or not shut off when the tank is full.

If daily rinsing of the recovery tank is not adequate to keep the switch clean, you may need to remove the float arm

for cleaning. The float arm can be removed easily by grasping it as shown below and twisting to remove. It is very

important that it be reassembled correctly in order to function. See Figure 12 for the correct orientation of the switch

float arm.
