4.2 FLUSH MODE
WARNING!
FLUSHING PROCEDURES MUST MEET EPA STANDARDS (AND/OR YOUR
DEPARTMENTAL PROCEDURES) IN ACCORDANCE WITH TYPE OF FOAM BEING
USED.
1. When power is supplied to the operator’s control panel, the area around
the switches on the smart-switch controller backlights (white) to indicate
the system is operational.
2. Connect the suction hose to the quick disconnect adapter on the opera-
tor panel and assure a tight seal.
3. Fully insert the suction tube into a container of clean, fresh water.
IMPORTANT !
PUMP FLOW RATE IS APPROXIMATELY 10.5 GPM (40LPM). THEREFORE, A
30 SECOND FLUSH CYCLE REQUIRES JUST OVER 5 GALLONS (19 LITERS)
OF WATER.
4. Place the FLUSH discharge hose into an empty container or discharge
to the ground. See
WARNING! note above.
5. Press and release the FLUSH button to begin flowing fresh water
throughout the system (valve and pump/motor) for approximately thirty
(30) seconds.
CLASS1 lights when the fill pump/motor is running.
6. As the clean water container empties, replace the container and repeat
Step 5 until all signs of foam residue are FLUSHED from the system.
7. To “force flush” the tank, press and HOLD the FLUSH button. The foam
pump/motor runs continuously until the button is released.
CAUTION!
IN THE “FORCE FLUSH” MODE, AN OPERATOR MUST ALWAYS BE AVAILABLE
TO MONITOR THE CAPACITY OF THE CONTAINER TO AVOID AN “OVERFILL”
CONDITION.
