The unit is not armed (indicator will be
red).
Pellet screen is not properly installed.
Loose or kinked tubing in control panel.
Trigger lines improperly connected.
Trigger valve failure.
Inline filter plugged (trigger return line).
Contamination in the trigger lines.
Open the air supply valve (E-Stop valve).
Turn Arm/Disarm switch clockwise (indicator should
turn green).
Make sure pellet screen fully engages safety interlock
switch when installed.
Check for loose or kinked tubes behind panel.
Reconnect if necessary.
Check trigger lines at machine and at the gun.

replace as necessary. Correct cause of contamination.
Check filter and replace element if necessary.

The PHX-150 starts,
but no ice comes out.
There is no dry ice in the hopper.
Ice rate is set too low.
Possible ice bridging inside the hopper.
Water ice accumulation in hopper.
Blast gun or hose plugged.
Incorrect auger rotation. (Auger should
turn counterclockwise when viewed from
the rear of the unit).
Airlock is not turning.
Load fresh dry ice into the hopper.
Turn Ice rate regulator clockwise to increase.
With pellet screen in place, use poker to break up the
bridge. This symptom is generally caused by poor ice
quality and high humidity areas.
Water ice forms in high humidity areas or when ice is
left in the hopper for long periods of time. Clean and
dry the hopper thoroughly before refilling.
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.
Remove motor/chain guard and turn selector switch
on ratchet motor to reverse direction.
