TROUBLESHOOTING
From time to time the performance of the F1000 may vary from the optimum or
the foam produced not meet the desired characteristics. Below is a list of
symptoms and a series of checks to restore proper perfomance. (Page number
references follow procedures).
1 | Gun doesn’t activate; mixing cartridge rod does not move when the trigger
is pulled:
Make sure the compressed air line is correctly connected and pressurized (2)
Check operation of air cylinder piston assembly (46)
Check operation of mixing cartridge (46)
2 | Chemicals are not dispensing, but gun is activating (mixing cartridge rod
moves when trigger is pulled):
Make sure mixing cartridge is not plugged (48)
Make sure nozzle is not plugged (10, 11)
Make sure valves on chemical tanks and hose end filter are open (10, 11)
Make sure red and blue chemical valves on gun are open (10, 11)
Make sure nitrogen pressure is on (10, 11)
Check filter on gun for blockage (42)
Check mixing cartridge orifices for blockage (48)
3 | Cannot reach proper A:B chemical ratio calibration:
Make sure chemical valves on gun and chemical tanks are open (10, 11)
Make sure nitrogen is connected properly (8)
Make sure nitrogen valve on both “A” and “B” chemical tanks
are open (10, 11)
Make sure proper procedure for calibration is followed (12)
Check for blockages in chemical flow:
Filter under gun (42)
Mixing cartridge (48)
Check valve assembly (44)
4 | Pressure relief valve on chemical tank is venting pressure:
Reduce nitrogen pressure on chemical tank (14, 16)
5 | Foam dispensed dosen’t “look right”:
Foam is sticky, spongy or is shrinking over time - check A:B ratio calibration.
Usually this is caused by an excess of “B” component. (12)
Foam is brittle or crunchy - check A:B ratio calibration. Usually this is
caused by an excess of “A” component. (12)
