Foam Tank Low Level Sensor
The unit is supplied with a connector for a low foam level sensor. The sensor is supplied
with the unit ready for installation (instructions supplied with the sensor).
The low foam level sensor is part of the Safety Interlock system and must be installed.
Note:
The low foam level sensor must be installed in the tank in the correct orientation.
The sensor has a raised boss on the casing and must be installed with this boss at 12 o
clock (top).
The foam tank requires a 23mm hole for secure fitting of the switch device and the
maximum allowable thickness of the tank wall material is 4mm.
The centre of the level switch should be located a minimum of 40mm above the foam
concentrate outflow to the foam pump.
Additional Installation Points
Foam Tank to Foam Pump
The foam feed line must not at any point be lower that the foam pump; have a 13mm
bore and be fitted with an isolating tap for maintenance purposes. The isolating tap
should be located as close to the tank as possible. A flushing point should be fitted
close to the isolating tap to ensure that the maximum length of hose line can be flushed
out. The flushing line should also be fitted with an isolating valve.
The foam tank must be located to provide a positive head of foam concentrate to
the FoamLogix unit, and the supply hose should be arranged to fall gradually
from the tank to the foam pump inlet to avoid air pockets. A tank drain valve must
also be fitted.
The foam tank should be made of plastic or stainless steel, with a volume greater than
the vehicle main tank by a factor of 0.005. Alternatively, a volume of at least 25 litres
may be preferred to allow an entire drum of foam agent to be contained.
Note:
To ensure correct operation of the FoamLogix pump, all connections must be
secure and pressure tight.
