WET SYSTEM OPERATION
4-22
Maintenance
Clean and replace the air pump and in-line solution filters regularly to extend the lift of the pump. The air
pump has one sponge and one felt filter.
Freezing
When operating in temperatures at or below freezing, ethylene-glycol-based antifreeze may be added to
the water and soap tanks.
If the system will be exposed to freezing temperatures overnight:
1. Pull the suction tube out of the tank and expose it to the air.
2. Close the soap valve and run the system for 10 to 15 seconds to clear the foam solution from the
pump and solenoids.
For long-term storage:
1. Drain the tank of the foam solution and run fresh water through the entire system.
2. While the unit is running, blow air through the suction tube until the system is dry.
3. Flip the power switch to dry the other side.
