©HALE PRODUCTS, INC. Our policy is one of continuous development. We therefore
reserve the right to amend specifications without notice or obligation.
NOTE:
It will be necessary to turn OFF the foam system if foam operation is no longer desired.
3. Run water through the CAFS discharge system to flush out the foam agent.
4. Close the CAFS discharge valves.
5. Shift the truck transmission from DRIVE to NEUTRAL and shift the water pump VPS from PUMP
to ROAD mode.
6. If freezing conditions are expected, drain the manifold, pump, water strainer and CAFS heat
exchanger.
OVERHEAT SHUT DOWN
1. Should the compressor oil temperature reach 220
o
F [105
o
C], a control panel warning indicator will
appear on the screen. The compressor can sustain 220
o
F [105º C] for short periods without
damage.
2. If the compressor oil temperature reaches 230
o
F [110º C], the drive clutch will automatically
disengage. This will stop the compressed air supply and only foam/water solution will be
discharged. The compressor cannot be re-engaged until the unit has been cooled and the pump
input speed is returned to below 900 RPM.
3. The most probable cause of compressor overheating is insufficient cooling water flow.
FLUSHING
When returning the apparatus to ready condition after using class B foam, the Hale Foam unit foam
pump
must
be flushed. This is because some Class B foam concentrates deteriorate rapidly. It is
recommended to flush for the preset time in the SmartCAFS.
NOTE:
Approved class A foam concentrates do not deteriorate at the rate of class B foam concentrates.
Provided that an approved class A foam concentrate is used and the system is used within 30 days,
flushing is not required. After class B foam concentrate has been used, flush the system then select
class A.
For detailed flushing instructions, please refer to the
Foam unit Model 3.3/5.0/6.5 Manual
