Plumbing Notes:
Remove the red shipping plug in the foam concentrate pump and replace it with the yellow vented cap/
dip stick. Check the oil level in the pump.
Locating the ow sensor in the plumbing system is critical. Guidelines for selecting ow sensor locations
are outlined in Install Flow Sensor(s).
All components on the suction side of the concentrate pump should be as close as possible. The one exception:
There needs to be a 10" minimum section of hose on the concentrate pump input for vibration absorption.
Mount foam tank check vales directly on the ABF selector if possible or mount as close to the valve as
possible. All concentrate hose runs should be as short as possible.
All lines and ttings down stream of the ush valve are required to be for high pressure. This would
include the hose between the tank check valve and the tank line tee tting.
Pay attention to ow direction of check valves and strainers.
The tank to valve to foam pump lines should be plumbed as if they were gravity feed lines. ie. The tank
needs to be higher then the valve and both higher then the foam pump - hoses should be continuously
declining. Do not leave loops or traps in the hose lines.
Recommended hose sizes are minimum sizes, the larger the diameter for B foam supply line, the better.
The inside of suction hoses need to be smooth. Clear hose is recommended on suction lines.
The calibration hose can be permanently installed or connected as needed.
The tank ll line needs to be connected up-stream of the ow sensor.
