Dry ice cleaning equipment should not be operated without proper training and the consent of your
direct supervisor or management. The information contained in the User’s Guide will provide all
the tools necessary for proper operation, safety, maintenance, and troubleshooting of the
equipment. Read and understand the contents of this guide before using or servicing your
machine.
Equipment Usage
Your new cleaning system was designed for use in an industrial environment. Proper safety precautions should be
practiced, observed, and monitored at all times. Be especially careful when blasting around materials that can
shatter. Dry ice blasting adapts to many types of applications, but the high velocity pellets can cause damage to
fragile items or substrates of low integrity. Remember NEVER to direct the blast stream at yourself or others.
Asphyxiation Hazard
Sublimation of dry ice creates CO2gas. This gas is 40% heavier than air, and thus displaces
oxygen in low-lying areas and enclosed spaces. When blasting, always have adequate ventilation
in and around your workspace. Contaminated compressed air (or nitrogen) used as a propellant
may greatly increase respiratory risk. A “High CO2” sensor/monitor with indicators is a
worthwhile investment and can help prevent accidental asphyxiation.
Noise
Blasting equipment generates a high velocity air flow from the nozzle. This air flow creates friction as it passes
through normal static air, resulting in high decibel noise levels. Though these levels can be controlled somewhat by
altering pressures and flow rates, ear protection is required in all blasting situations. Additional noise factors include
the object being cleaned, distance from the targeted material, media quantity being used (ice rate), and acoustic
surroundings. If you are unsure about blasting in an area around you or fellow co-workers, consult with your safety
director for advice and/or safety parameters before beginning work.
Emergency Stop Mechanism and other ways to stop blaster in Emergency
The PHX-200 is equipped with a Mushroom Head Emergency Stop Button. Pushing this button will stop the unit
immediately, requiring reset sequence to rearm the gun trigger.
There is also the ARM/DISARM Selector Valve. Disarming while blasting will send the blaster into the purge mode
and will purge at 45 PSI for three seconds.
In addition, closing the System Supply Valve will deprive the unit of air power and stop the system. Located on the
center of the handle is a locking device where a padlock can be installed to “lock out” the blast unit and prevent use.
Protective Gear
Before beginning work, make sure you have the proper protective gear for the job. This includes
the basics: Ear plugs or muffs (or both), eye protection, gloves, long sleeves, long pants, and
safety shoes. Dependant upon specialized cleaning jobs, you may also need other protective items
such as: self-contained breathing apparatus, respirator, grounding straps, skin protectors, jumpsuit,
special clothing, or other equipment as deemed necessary by your company’s safety regulations.
The training process for using your new PHX-200 is relatively easy, but there will still be a “learning curve” where
technique and experience is concerned. The operator should understand that high velocity air exits the gun barrel.
Upon triggering the gun, the operator will experience a small reactive thrust, which increases or decreases
depending on pressure settings and air flow. Operator fatigue may also be an issue, relating to blasting angles,
pressure settings, dwell times, work area, temperatures, physical conditioning, and time on duty. Do not exceed
allowable limits as set by company policy and safety personnel.
High Velocity Particles
High velocity particles exiting the gun may cause serious injury. Never aim the gun at yourself or
others. The ice is sometimes difficult to see in the blast stream. However, never use your hand,
foot, or any other body part to check pellet flow. Do not blast delicate or fragile items or
equipment parts (i.e. glass or plastic gauge faces). Damage may occur.
Moving Parts
Though the moving parts inside your PHX-200 are minimal, they are critical components and serious injury may
occur if safety parameters are not adhered to. Your machine incorporates an auger that turns, feeding dry ice pellets
into the delivery system. A safety sensor is activated to immediately stop the auger from turning anytime the pellet
screen is removed. Do not attempt to override this sensor. The auger drive motor and chain are shielded by a
protective guard and should never be operated without the guard in place. Do not attempt to operate the airlock
assembly while detached from unit. Always follow shut-down procedures before attempting any periodic
maintenance or repairs.
Burn Hazard
Dry ice is extremely cold, -109°F (-78°C). Do not allow skin to directly contact dry ice or the
outside of the PHX-200 hopper while it is loaded with dry ice. Doing so may cause severe deep
tissue burns. Always wear heavy-duty insulated gloves and long sleeved clothing for protection
when handling dry ice or cold equipment during use.
Static Discharge
The gun of the PHX-200 is grounded through the blast hose to the frame, then through the special
conductive front wheels; therefore any significant amount of static discharge is uncommon. Still,
the possibility exists that minor static discharges can occur pending weather conditions, the travel
of high velocity ice particles, etc. If static discharge is experienced, wear the grounding wrist strap
supplied with your unit. Also, you may wish to add an additional wire from the machine to a good
earth ground, AND ground the item that you are blasting.
Caution: Static discharge may ignite flammables. Be aware of your surroundings!
Lower Limit Blast Pressure
The PHX-200 utilizes an additional regulator that maintains the blast pressure at 45 psi, even though it is turned all
the way down and blast gauge reads zero.. When conducting function tests while the unit is energized, take the
necessary precautions to insure that the blast gun is secured and pointed in a safe direction.
Present and Stored Air Hazard
The control circuitry of this machine may trap air in and between associated components. Close System Supply
Valve to vent unit before any maintenance or service is performed to prevent accidental release of trapped air. Air
may also be trapped in the Airlock Supply Hose. When removing hose first loosen fitting and let the air bleed out
until completely depressurized. When system supply valve is closed there is still supply air present to the blast air
pilot filter, regulator and gauge. Be sure that inlet supply air is removed at the source when servicing the blast air
pilot filter, panel regulator or gauge.
Lock Out/Tag Out Precaution
Do not perform any type of service to this equipment until all lock out/tag out procedures have been followed
according to your company’s safety regulation guidelines. As mentioned previously (page 6),
a lock out hole is provided in the System Supply Valve handle if required.
This User’s Guide is the best tool available during the initialization of your new PHX-200 Dry Ice Cleaning
System. It contains all the information necessary for the proper installation, safety, operation,
maintenance and troubleshooting right at your fingertips. Familiarize yourself with its’ contents before
operating this equipment.
CONNECTING THE AIR SUPPLY
Since the PHX-200 is an “all pneumatic” design, it is critical that only clean, dry air be supplied to the unit.
Air containing excess amounts of moisture, oil, rust, or other contaminants may clog filters and damage
the logic control and internal components. A good desiccant or refrigerant dryer should be installed
between your compressor and the PHX-200. The dew point should not exceed +40°F/+4.4°C. Good air
quality will save you time for repairs and increase the life of the unit. The unit is supplied with a 1” female
NPT thread.
1. A 1” JIC male inlet fitting is recommended. Connect air supply hose to the PHX and extend the
whip check as far down the hose as possible. (pic 1,2,3)
2. Wearing hearing protection, blow down the air source at the drop to remove any accumulated
moisture. This helps to insure equipment performance. (pic 4)
3. Connect the air supply hose to the air source. (pic 5)
Caution! Maximum air pressure supplied to the PHX-200 should never exceed 250
PSI!
1. Use 1¼” and 1½” wrenches to connect the gun to the end of the blast hose with the shorter
length trigger lines. Do not over-tighten. (pic 1)
2. Connect the respective trigger lines (different sizes) to the gun, pushing firmly into the quick-
connect fittings. (pic 2)
3. Install the nozzle by a) twisting threaded retainer to completely ‘open’ position; b) place
nozzle into end of blast gun; c) tighten retainer to secure the nozzle. Improper seating of the
nozzle in the gun may result in air leakage. (pics 3, 4, 5)
4. Using the 1½” wrench, connect the remaining end of the blast hose to the front of the PHX-
200. (pic 6)
5. Connect the two trigger lines to the unit, pushing firmly until seated. Failure to attach trigger
lines will result in the non-functioning of the unit. (pic 7)
6. If necessary, ground the item you are blasting.
CAUTION! Do not attempt to perform any maintenance or service on your PHX-200 unless safety
guidelines and lock out/tag out procedures have been satisfactorily met!
Before pressurizing the machine each day/shift, a quick preventive maintenance inspection should be
performed to ensure that your unit operates problem-free now and in the future.
1. Check the Filter/Separator sight glasses for accumulated moisture or remove the canister to
inspect the filter for contamination. Clean canister and replace filter element if needed. A
COLLAPSED FILTER ELEMENT WILL CONTAMINATE THE SYSTEM. (pic 1)
2.Visually inspect lubricators to confirm fluid level is adequate. (pic 2 & 3) The bowls are
pressurized so be sure to close the System Supply Valve if removing bowl. (See page 19 for
detailed instructions on adding oil.)
3. Inspect hose assembly for cracks or leaks. Replace if necessary.
1. Before you begin loading dry ice, it is important that you have the protective gear previously
mentioned in the “Safety Precautions and Warnings” section (page 6). This includes basic items
such as earplugs or muffs (or both), eye protection, face shield, heavy-duty gloves, long sleeves,
long pants, and safety shoes. (pic 1)
2. Lift hinged metal lid to expose hopper. BE AWARE OF AND KEEP CLEAR OF PINCH POINTS
(pic 2)
3. Use a sturdy scoop or similar device to load dry ice pellets into the hopper. (pic 3) Be careful not
to inhale concentrated CO2gas during the loading process, as it will temporarily rob you of
oxygen. If overexposed, get fresh air immediately. Signs of overexposure include dizziness, cold
sweats, headaches, nausea, and heavy breathing.
4. Close the lid on the hopper. This will prevent airborne contaminants from inadvertently falling
through the pellet screen to the ice and ultimately ending up on the surface you are cleaning or
damaging internal airlock parts. (pic 4)
1. Slowly open the main air supply valve (source). (pic1)
2. With the gun secured and pointed in a safe direction, slowly open the system supply valve on the
PHX-200. To open pull outward on locking collar and turn handle to the left. (pic 2)
Pic 1
SETTING THE PANEL REGULATORS
(NOTE: The Panel Regulators may be adjusted at any time.)
ICE RATE CONTROLS
1. If locked, pull the ICE RATE knob outwards to unlock it.
2. Turn the knob clockwise to desired pressure. If unsure, start at about 25 PSI, then adjust the rate
up as necessary for your particular blasting application.
Note: It is normal for the pressure to drop 3-7 PSI (proportional to the set pressure)when
trigger is pulled, so adjust accordingly Experience will dictate proper settings.
Pic 2
3. Push the knob in to lock the ice rate.
BLAST AIR CONTROLS
1. Loosen jam nut on the tee handle to unlock it.(1/2” wrench)
2. Turn tee handle clockwise until desired pressure is reached. The PHX-200 has a blast pressure
range from 45-250 PSI. If you are unsure or are concerned about damage to the item being
blasted, start at a lower blast pressure and increase it gradually until the optimum performance
level is achieved.
3. Tighten jam nut to lock the blast air pressure.
Note: The PHX-200 is factory set to purge air and ice 3 seconds at 45 PSI after trigger is released
to clear the airlock and hose and prevent any clogging on the next trigger pull.
The Arm/Disarm Selector is used to enable the gun trigger. It also enables the main control system.
Always Disarm when not blasting, especially when gun is unattended.
WARNING: If trigger is engaged when arming, the unit will start blasting immediately!
(NOTE: The PHX-200 will not arm if the E-STOP button is depressed, safety screen is removed, or
trigger supply line is disconnected.)
1. Check E-STOP button. The mushroom head has a push/pull operation. In the depressed position
the E-STOP button disables the arm system and the purge delay system. Pull out if required. (pic
1)
2. Again, be sure the gun is pointed in safe direction and secure. Turn the Arm/Disarm switch
clockwise to arm the PHX-200. The indicator will turn green, and the momentary switch will return
to the center position. The gun trigger is now live. Blast operations may now begin. (pic 2)
3. To Disarm, turn counterclockwise, trigger will be disarmed and indicator will turn red. (If blasting is
in process when Disarmed, the PHX-200 will enter its 3 second low pressure purge cycle then
stop. Blasting cannot be resumed until trigger is rearmed.)
Pic 1Pic 2
READY TO BLAST
1. Be sure to be wearing proper protective gear at this point.
2. Hold the gun and nozzle handles securely. Aim the gun at the target or in a safe direction. Brace
yourself as there is a noticeable thrust when you pull the trigger. More reactive thrust will
experienced as blast pressure setting is increased.
3. Push upwards on the safety catch to release and pull the trigger to initialize blasting. (pic 3)
There are a few different ways to stop the blasting cycle. The PHX-200 reacts differently to each method.
They are as follows:
1. Normal Stop: (pic 1)
Under normal circumstances the way to stop blasting is to simply release the trigger. This will
stop the auger and blast air. The airlock and 45 psi purge air will continue for 3 seconds toclear ice from hose then stop. Trigger remains armed and ready for more blasting. Pull trigger
again to resume.
2. Disarm Stop: (pic 2)
If someone besides the operator needs to stop the blasting operation they can turn the Arm
Selector counter-clockwise to Disarm the trigger. This will cause the indicator to turn red and
blasting will stop and end with 3 sec. 45 psi purge cycle (as if trigger was released.) Trigger
will need to be armed again before blasting. Be sure trigger has been released and gun is secure
before re-arming the trigger. (NOTE: If trigger is engaged when arming, the unit will start blasting
immediately. )
3. EMERGENCY STOP: (pic 3)
In case of an emergency push the red mushroom head EMERGENCY STOP button. This willstop all functions instantly and disarm the trigger. Button will remain depressed. To reset pull
button back out. Trigger will need to be armed before blasting.
4. System Supply Stop: (pic 4)
Closing System Supply Valve will stop all airflow, disarm and vent the control system.
1. When blasting is complete, release the trigger and wait for airflow to stop. (There is a short
delay while residual ice is purged at 45 PSI from the blast hose. Keep gun pointed at the
target until air stops flowing! (Pic 1)
2. Turn the Arm/Disarm switch counter-clockwise. The indicator will turn red, and the
momentary switch will return to the center position. E-Stop button may be depressed if
desired. System will not Arm if the E-stop button is depressed. (Pic 2)
3. Close System Supply Valve. Lockout collar will latch and system will vent. (Pic 3) System
may be locked out with a padlock through the lockout collar.
4. Close the air supply valve at the source. (Pic 4)
5. Vent remaining air from the machine and supply hose by opening the System Supply Valve
approximately halfway. After the air stops flowing, you may fully close the valve. Lock Out
valve if required. (Pic 5)
6. If moving the unit to another location for blasting, disconnect the supply hose from the unit.
Wrap the blast hose with gun connected carefully around the machine handle for quick
transport. Use extra caution when moving unit while hoses are connected. For extended shut
down remove ice from hopper and disconnect blast hose. Roll up hoses and store in a safe
location. (Pic 6)
CAUTION! Do not attempt to perform any maintenance or service on your PHX-200 unless safety
guidelines and lock out/tag out procedures have been satisfactorily met!
DAILY PREVENTIVE MAINTENANCE
Before pressurizing the machine each day/shift, a quick preventive maintenance inspection should be
performed to ensure that your unit operates problem-free now and in the future.
1. Check the Filter/Separator sight glass for accumulated moisture or remove the canister to
inspect the filter for contamination. Clean canister if needed. A COLLAPSED FILTER
ELEMENT WILL CONTAMINATE THE SYSTEM (See page 20 for canister removal and filter
replacement procedure). (pic 1)
2. Visually inspect Auger Drive Lubricator to confirm fluid level is adequate. (pic 2) The bowl is
pressurized so be sure to close the System Supply Valve if removing bowl. (See page 19 for
detailed instructions on adding oil.) OPERATING WITHOUT OIL WILL DAMAGE THE
MOTOR AND VOID WARRANTY.
3. Visually inspect Airlock/Vibrator Lubricator to confirm fluid level is adequate. (pic 3)The bowl
is pressurized so be sure to close the System Supply Valve if removing bowl. (See page 19
for detailed instructions on adding oil.) OPERATING WITHOUT OIL WILL DAMAGE THE
MOTOR AND VOID WARRANTY.
4. Inspect hose assembly for cracks or leaks. Replace if necessary. (pic 4)
CAUTION! Do not attempt to perform any maintenance or service on your PHX-200 unless safety
guidelines and lock out/tag out procedures have been satisfactorily met!
There are two lubricators on the PHX-200. One is for the Auger Motor located below the control panel,
and the other is for the Airlock Motor and Hopper Vibrator located on the opposite side of the machine
above the Blast Hose Connection.
Visually inspect oil levels daily and add oil before lubricator bowls are empty. If wet dirty air is being used,
water, dirt, rust and emulsified oil can accumulate in lubricator bowls, making it look like they are full of oil.
A periodic “closer look” is recommended and an oil change is recommended if it is contaminated with
water. To add oil follow these steps.
1. Close System Supply Valve and wait a few seconds before attempting to add oil. (Pic 1)
2. Grasp bowl, unscrew bowl from lubricator body. Be sure to locate the O-ring. (Pic 2)
3. Add 10W tool oil until level with max fill line. Be sure that the O-ring is properly seated in the
top of the lubricator bowl. Reinstall the bowl. (Pic 3)
Pic 1Pic 2Pic3
4. Oil may be added by removing top plug on lubricator and adding oil there. (Pic 4)
CAUTION! Do not attempt to perform any maintenance or service on your PHX-200 unless safety
guidelines and lock out/tag out procedures have been satisfactorily met!
To ensure that your dry ice cleaning system operates correctly and continues to provide reliable
performance levels, the separator needs to be inspected regularly. Poor filtering leads to excessive
moisture being passed into the control system, airlock, blast gun, and ultimately to the targeted surface. A
discolored filter element should be replaced. A plugged element will collapse allowing dirt and
contamination to pass and cause damage to the system.
To gain access to the filter element, follow this simple procedure:
1. Close System Supply Valve to isolate Filter/Separator. Lockout collar will latch and system
will vent. Lock Out with padlock if required. (Pic 1)
2. Press locking tab on separator canister and turn in either direction to disengage. (Pic 2)
3. Lower the canister straight down to clear filter element. (Pic 3)
4. Remove baffle by turning counter-clockwise. (Pic 4)
5. Filter element should come off with baffle. If not, pull gently downward on element. (Pic 5)
6. Inspect filter element and deflector. (Pic 6) Install new element by reversing steps.
To avoid damage to the stem, be very careful when removing the bowl, baffle and element to
completely clear the stem before pulling out element. Undo pressure on the stem can cause
damage to regulator requiring stem replacement.

If the unit is ready to blast (Arm/Disarm indicator is green), but does not start or only partially starts when
the trigger is pulled, it may indicate the need to change the Trigger Line Filter element.
To perform this:
1. Locate the filter housing on inner leg of the PHX-200 near the airlock motor. (pic1)
2. Disconnect the tubing from filter housing push fittings (both ends), then remove filter housing from
unit. (pic 2)
3. Using two ¾” wrenches, remove the cap from the filter housing to expose the sintered bronze
filter element. (pic 3)
4. Remove filter element. Important: Remember proper configuration of internal spring in
relation to the element. Improper installation will result in the non-operation of the unit.
(pic 4)
5. Install new filter element and housing by reversing steps 2-4.
Pic 1Pic 2
Pic 3Pic 4
There is also another identical element for the blast air pilot filter. It is located on the air system.
TO REPLACE THIS ELEMENT THE SYSTEM MUST BE DISCONNECTED FROM THE AIR SOURCE
AS IT IS PRESSURIZED EVEN WHEN THE SYSTEM SUPPLY VALVE IS CLOSED.
Replacement is the same but do not remove housing from system. Just remove tube and separate as
CAUTION! Do not attempt to perform any maintenance or service on your PHX-200 unless safety
guidelines and lock out/tag out procedures have been satisfactorily met!
AUGER DRIVE CHAIN
Over time, the stainless steel drive chain may stretch; it is recommended that the drive chain
tension be checked after every few months. A loose chain can skip or bind and can cause damage to the
stainless steel sprockets. Also a chain that is too elongated will not mesh properly with the sprockets and
should be replaced. A chain that is over tightened may stretch and cause premature chain failure and
sprocket wear.
Checking / Adjusting the Drive Chain Tension
1. Use a 5/32” hex key wrench to loosen two screws located at the top of the motor/chain guard.
Do not remove the screws. (pic 1)
2. Gently tilt the unit forward and remove third screw located at the bottom of the guard. (pic 2)
3. Remove the chain guard to reveal drive chain. (pic 3)
4. Apply pressure to mid-span point. Movement should not be more than 3/32”. (pic 4)
5. If tension adjustment is necessary, loosen the two upper hex screws on the motor mounting
plate.(pic 5)
6. Locate the drive chain adjustment screw at the very top of the motor mounting plate. (pic 6)
Checking / Adjusting the Drive Chain Tension (cont.)
1. Use a 7/16” box wrench to loosen the adjustment screw retaining nut by turning counter-
clockwise. (pic 7)
2. Hold the retaining nut in position and use a 3/16” hex key wrench to adjust the screw
(clockwise to increase tension, counter-clockwise to relieve) until proper tension is achieved.
(pic 8)
3. Tighten the retaining nut to lock the adjustment screw into place. (pic 9)
4. Tighten the two upper hex screws on the motor mounting plate. (pic 10)
5. Verify that the auger directional switch on motor ratchet is rotated fully clockwise. (pic 11)
6. Install the chain guard and tighten the three screws that secure the guard into place (pic 12)

VIBRATOR
The Vibrator Pad (30031-001) will wear over time allowing the piston to strike the bare frame
metal. The Pad can be replaced by removing the four mounting bolts.
The Vibrator can be service by removing it from the frame. Remove the two screws that secure
the end cap. Use caution not to tear the gasket and remove end cap. Remove piston and clean any
debris and rust from bore and piston using ATF fluid. Reassemble piston and end cap. Piston should
move freely. Reinstall unit to frame.
Diminished performance or a noticeable drop in blast pressure at the gun may indicate a worn or
damaged component in the airlock. Most airlock problems are typically caused by a foreign object
(airborne or otherwise) falling through the hopper pellet screen, mixing with the dry ice pellets, and
becoming lodged inside the airlock or doing damage as it passes through to the blast hose and gun.
(Note: You can avoid unnecessary expense and repairs by closing the hopper lid after filling with
ice and prior to blasting.) In order to properly inspect or replace the critical components, the airlock
assembly must be removed from the unit. To do this:
1. Remove air supply hose from the PHX-200. Also remove the gun and blast hose assembly if
attached. (pic 1)
2. To avoid spillage, remove the lubricator bowls and set aside. (pic 2)
3. Detach the inlet blast air hose coupling from airlock assembly inlet. (pic 3).
4. Carefully place some blocks on the ground. Lay the unit on the blocks with the control panel
facing down using care to prevent the regulator and e-stop button from being damaged. Be
careful that hinged metal lid does not “flop” backwards suddenly during this procedure. (pic 4)
5. Remove the airlock motor air supply lines from the push fittings. (pic 5)
6. Remove the large cotter pin from the airlock retaining latches. (pic 6)
8. Remove complete airlock assembly from unit and move it to a workbench. (pic 8)
9. Use a 3/16” hex key wrench to remove six housing bolts from bottom of airlock assembly. (pic 9)
10. Separate the housing and set bottom half aside. (pic 10)
Pic 7Pic 8Pic 9Pic 10
Rotor:
11. Carefully remove the rotor from the spline and
inspect. Replace if damaged. Before installation
of new rotor, clean and inspect the pads, motor,
spline and internal walls of the housing for
damage. If all parts are good, install the new
rotor onto the spline. (pic 11)
12. Reinstall airlock assembly onto the PHX-200 by
reversing steps 1-10.

Airlock Motor / Spline:
13. While the housing is disassembled, inspect the motor and spline. If replacement is necessary, the
motor will need to be removed from the housing. (pic 12)
14. Use a ¼” hex key wrench to remove the two mounting screws, then remove the motor assembly.
(pic 13)
15. Use two wrenches to remove the spline from the motor and install new one. (pic 14)
16. Be sure centering ring is in place and reinstall motor.
17. Reinstall airlock assembly by reversing steps 1-11.
Engine Lubrication- Be sure air lubricators are maintained as outlined in equipment
manual. If wet dirty air is being used, water, dirt, rust and emulsified oil can accumulate
in lubricator bowls, making it look like they are full of oil. A periodic “closer look” is
recommended and an oil change is recommended if it is contaminated with water.
Cleaning Engine- Water and rust in the compressed air or dust and wear particles can
cause sticking of vanes, valves etc. This can be prevented by removing muffler, flushing
with a few drops of oil, running the motor for 5-10 seconds and absorbing the oil in a
cloth. Replace or reinstall muffler. Protect the engine this way before long shutdown
periods. DO NOT RUN THE AIRLOCK FOR LONG PERIODS WITHOUT ICE.
Muffler-Over time the muffler can become clogged with particles and restrict exhaust
flow which will make the motor run slower. It is recommended to periodically replace the
muffler. (P/N 50203-001)
Maintenance and repairs must be carried out exclusively by authorized personnel.
Overhaul- To achieve the best service life under normal operating conditions, regular
overhaul and cleaning should be carried out every 12 months or 2000 hrs., whichever is
sooner. Overhaul should be carried out more frequently under more rigorous operating
conditions.
Lubrication- Planetary gears, ball and needle bearings and seal ring should be
lubricated with grease in conjunction with the regular overhaul of the motor. Molykote
BR2 Plus gives long intervals between lubrications.

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.
Airlock Speed/Vibrator Stength/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. This setting is critical as these systems are balanced to run off the same
pressure setting.
To check:
1.Close System Supply Valve
2.Remove large black tube from regulator and connect a pressure gauge to the fitting where tube was
removed.
3.Open System Supply Valve
4.Gauge should read 45 PSI.
To Set
1. Attach gauge and check pressure as described above.
2Remove Right Side Cover to access Regulator.
6. Locate Regulator knob. Pull up on the knob to unlock.. Use care working around the small tubing
4. Back off regulator pressure, then raise the regulator by slowly turning handle until 45-PSI is reached.
5. Lock in setting by pushing down on knob.
6. Close System Supply Valve and reconnect large black tube.
7. Check operation of unit and replace side cover.
Before attempting to troubleshoot, be sure all pre-set factory pressure settings are correct. Problems can
stem from these regulators being out of adjustment. to be sure to rule these settings out, they should be checked
first thing. SEE “FACTORY SETTINGS”.
Contaminated air is the cause of most problems that may occur in pneumatic systems. There are Filters that if
maintained properly will perform exceptionally well. However excessive moisture and contamination combined
with lack of maintenance will clog the filters, and if not replaced will finally collapse and allow all the dirt, rust and
crud to enter the system. The best way to avoid problems is to know the air you are using and maintain filters
accordingly. For fewer filter changes take steps to provide clean dry air to the PHX.
The use of the Model 200 Schematic and the Tubing Diagrams are extremely helpful when troubleshooting
the PHX. Have this guide handy if calling Phoenix Unlimited for technical support. Also, assembly drawings are
included in the back of this guide.
The PHX-200 can be function tested for short periods with a standard ¼” shop air hose. Do not run airlock dry
for extended periods. You will need the following items to set it up. Fittings to connect shop air hose to the 1” inlet
on the PHX-200. 1” JIC Cap to cap off blast hose connection. Cap off Airlock outlet at the blast hose connection.
Connect air to the machine. Operate trigger as usual. To operate for longer times, remove and cap off Blue pilot
tube from the Airlock Control Valve, this will prevent the airlock from running dry for too long while you diagnose.
A Note on Tubing Color and Control Systems
When troubleshooting, it is essential to understand the 6 control and distribution systems in the PHX. Each
system is identified by its control tubing size and color. This information will help point you in the right direction.
The systems and respective tubing are as follows:
