FACTORY SETTINGS
There are two factory set and locked regulators on the PHX. Problems can stem from these regulators
being out of adjustment.
There is also a speed control valve that controls the duration of the purge delay. This allows the Airlock
Motor and the purge air pressure to continue to run for a time period to clear the airlock and hose of ice.
Control Air Regulator
This regulator protects the entire control system. This setting is critical as the system needs 70-80 PSI,
and settings over 90 PSI can damage control system components
.
It is located on the right side of the air
system, mounted on the main filter regulator. This regulator has a built in gauge and should be set to 5.5
BAR (70-80 PSI).
Airlock Speed/Vibrator Strength/Purge Pilot Regulator
This regulator controls the RPM of the Airlock Motor, the vibrating force of the Vibrator and the Purge
Air Pilot pressure to the Filter/Regulator.
To check or set pressure,
Purge Delay Speed Controller
The factory setting of this delay is 3 seconds. This time period can be easily adjusted, as the Speed
Controller is readily accessible, located under the Control Shelf just to the left of the Lubricator.

Control Air Regulator
Set to 5.5 BAR (70-80 PSI)
1.Back off Blast Air Regulator all the way. {If locked, pull knob
to unlock. Turn counterclockwise until knob stops. Do not force
knob} Gauge will now show the pressure that controls the rpm of
the airlock motor, strength of the vibrator and blast hose purge
pressure. The gauge should read 40-45 PSI.
2.To adjust, pull Airlock Regulator knob to unlock, Observe
Blast Air Gauge and turn knob to adjust pressure to about 40–45
PSI. Push knob back in to lock.
1.Locate Speed Controller knob, loosen knurled jam nut. 2. Adjust
knob. Turn valve in to increase delay or back valve out to shorten
the delay. 3. Cycle the trigger on and off. Repeat until purge cycle
stops 3 seconds after trigger is released. To lock setting, tighten the
jam nut.
WARNING: If valve is closed completely the purge cycle
will not disengage.
