Note: When the side mount low level sensor senses a low concentrate condition
the system operates for an additional one minute unless the foam concentrate
level is restored. If the foam concentrate level is not restored the system SHUTS
DOWN. When locating the side mount low tank level sensor on the tank sufficient
foam concentrate should be present for one minute of operation at the rated flow.
3. Coat the threads of the sensor with a suitable sealant and insert into
tank fitting. Tighten sensor making sure the float is on the top of the
sensor. (See Figure 3-37: “Low Level Sensor Mounting Options” on
page 93.)
4. After installation, check operation of the side mount low tank level sen-
sor with a powered test light. With no foam in the tank, the light should
be ON. If light does not illuminate, rotate the side mount low tank level
sensor until the test light is ON.
Bottom Mount Installation
The bottom mount foam tank low level sensor must be mounted into the bot-
tom of the foam tank. (See Figure 3-37: “Low Level Sensor Mounting
Options” on page 93.)
1. The sensor, as supplied, is threaded into a bushing (1” [25mm] NPT
threads) and is designed to be installed from the outside of the foam
tank through a bulkhead fitting or boss with 1” (25mm) FNPT threads.
2. Mount the sensor in the bottom of the foam tank in an upright position.
Use a suitable sealant to prevent concentrate leakage. (See Figure 3-
37: “Low Level Sensor Mounting Options” on page 93.)
3. Check low tank level sensor operation with a powered test light. With no
foam in the tank, the light should be ON.
4. If not, remove the clip from the end of the sensor. Remove float and
reinstall 180° out of position. Re-install clip.
Top Mount Installation
The top mount low level sensor assembly is available for installations where
the sides or bottom of the foam tank are not accessible or sensor service is
required without draining the foam tank.
The sensor assembly is flange mounted in an access hole at the top of the
foam tank. The two section telescoping assembly permits adjustment of the
low tank level sensor position for various foam tank depths, from 31- 1/2” to
60” (800mm to 1,524mm). (See Figure 3-39: “Top Mount Sensor Dimen-
sions” on page 95.)
