Discharge outlet, Blast Hose
or Gun plugged.
Decrease blast pressure to 45 psi. Remove blast
hose from unit. With trigger lines still attached,
trigger the unit to clear ice from the discharge
outlet. Reattach hose and remove nozzle from
gun. Trigger again to clear ice from hose and gun.
Reattach nozzle.
Nozzle plugged with ice or
foreign material.
Disarm PHX-200, Remove Nozzle and visually
inspect, remove blockage. Reinstall Nozzle.
Be sure hopper lid is always closed to prevent
any foreign material from entering blast system.
Incorrect Auger rotation
Remove chain guard and turn switch on ratchet
motor to reverse direction. This would only be
changed if chain guard has been off since the last
time it worked correctly.
Auger Motor or Airlock Motor
not turning
See respective section if one of these motors is
not turning.
BLAST GUN PLUGS
REPEATEDLY
Ice rate set too high using low
flow nozzle and/or fragmentor
Reduce Ice Rate
Water accumulation inside Gun
and/or Hose. Blasting with wet
air can cause the water in the
air to freeze and plate out in the
Blast Hose ,Gun and Nozzle.
Eventually causing restriction
and plugging.
Defrost, Clean and dry the gun and hose. Check
incoming air supply for cause of contaminant and
correct.
AUGER DOES NOT
TURN
Ice Rate set too low
Increase Ice Rate pressure.
Foreign object in auger.
Remove object. Keep hopper lid closed to
prevent.
Test For Mechanical or Control
Problem,
Is air reaching ratchet motor
inlet?
Remove test port pipe plug
from ratchet inlet tee.
Pull the trigger.
Air should come from test port
and be controllable by the
ice rate regulator. Replace plug
after test.
If no, this indicates a control problem.
Test control valve.
If yes this will indicate a mechanical problem.
Check for Drive Chain tension, stretched Chain,
Check and adjust drive tension,
Replace stretched chain.
Auger sprocket should turn freely with chain
removed.
Check for mis-aligned or worn out ratchet motor.
Remove ratchet from drive assy and bench test,
repair or replace if required. Drive sprocket should
turn freely with ratchet motor removed.
Test for Control Valve
Problem #1
Does Blast Air come on when
trigger is pulled?
If no, check the control system, in particular the
trigger lines, trigger filter F3 and Trigger “YES”
valve L3,
If Yes, then the problem is probably the Control
Valve CV2,
go to next test.
