FACTORY SETTINGS
There are two factory set and locked regulators on the PHX. They are not readily accessible, so
the chance of someone randomly changing their settings is low. However, if problems arise they should
be checked. Many 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 running for a time period to clear the airlock and
hose of ice.
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.
To adjust:
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.
Control Air Regulator
This regulator protects the entire control system and the Auger Ratchet Motor. This setting is critical as the
system needs 70-80 PSI to operate properly, and
settings over 90 PSI can damage control system components.
Although there is a 90-PSI relief valve, do not set blindly,
Use gauge to check and set.
To check:
1.Close System Supply Valve
2.Remove small black tube from front of regulator and connect a pressure gauge to the fitting where tube was
removed.
3.Open System Supply Valve
4.Gauge should read 80 PSI.
To Set:
1.
Set up gauge and check pressure as described above.
2.
Remove Left Side Cover to access Control Air Regulator.
1.
Locate locknut on the T-Handle adjustment screw. Loosen locknut with 9/16” wrench. Use care working
around the small tubing not to snag it on the wrench or T-Handle.
2.
To Set: First back off regulator pressure by turning T-handle counter/clockwise, and then raise the
regulator by slowly turning T-Handle clockwise until 80-PSI is reached.
3.
Lock in setting by tightening locknut.
4.
Close System Supply Valve and reconnect small black tube.
5.
Check operation of unit and replace side cover.
