Filling Foam Tank
1.
Open the pressure relief valve on the top of the foam
tank before removing the tank lid. This will equalize
the pressure on the inside of the foam tank with that
of the atmosphere.
!
CAUTION
Open the pressure relief valve and allow all pressure to be re-
leased before the tank cap is removed. Failure to do so may
cause bodily injury.
2. Mix 1/2 to 1 quart of foam marker concentrate in the
10 gallon foam tank. Use an Application Systems
foam concentrate quart container to measure the
correct volume of foam concentrate. For smaller
quantities, the ratio is 1 1/2 to 3 ounces per gallon of
water.
3. Fill the tank with water. With hard water, add more
foaming concentrate. The lid must be sealed air tight
for proper foaming.
4. Check the condition of hoses and connections fre-
quently.
Operating the Foam Control Valve

Refer to Figure 7
2. Open the foam control valve on the foam control box
gradually, allowing several minutes for the liquid to
feed into the foaming cylinder on the boom.
3. Adjust the foam control valve to the desired output.
