MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
FOAM A TANK LEVEL INDICATOR GAUGE DOES NOT OPERATE PROPERLY
NOTE
FOAM LEVEL indicators operate as follows: "E" indicator will flash when the foam level in
tank is below 1/4 full. Indicators "E" and "1/4" will illuminate when foam tank is 1/4 full.
Indicators "E", "1/4", and "1/2" will illuminate when foam tank is 1/2 full. Indicators "E",
"1/4", "1/2", and "3/4" will illuminate when foam tank is 3/4 full. And indicators "E", "1/4",
"1/2", "3/4", and "FULL" will illuminate when foam tank is full.
FOAM LEVEL gauge "E" indicator will illuminate or flash whenever power is applied to
gauge.
Foam level probe is designed and calibrated to detect class A foam. Substituting class A
foam with other liquids will send a false signal to FOAM LEVEL gauge. If it is suspected
that foam system has been contaminated or compromised with different brands and/or
types of foam, drain foam tank (WP 0031) and fill with class A foam.
