FILLING THE FOAM MARKER SYSTEM–
Relieve pressure from the foam tank by opening the ¼”
ball valve on the side of the foam tank (fig. 4.39-1, item B). Close the ball valve after pressure is relieved.
Open the top 2” ball valve (fig. 4.39-1, item A). Add water to the tank, leaving enough room for the foam con-
centrate. Next, add the foam concentrate according to the label on the container. After filling is complete, close
the 2” ball valve on top of the tank. Start the sprayer’s engine and adjust the air pressure accordingly (see pre-
vious page).
Before performing any service or refilling
of the foam marker, shut the engine off
and relieve system pressure from the tank.
DO NOT stand directly over or
in front of valves when opening.
