Programming:
The below timer pictured is the standard SSAC model that allows the end user to select the "coins to start" and
the “total time" by settings series of dip switches. The number of "coins to start" dip switch is how many quarters
are needed to make the machine come on. In the below example, the "one coin" dip is selected which makes the
unit come on with one coin. The "total time" will then need to be set, but a good rule of thumb would be 4 minutes
which requires dip switches 3.2 and .8 to be set to on. This scenario means 1 quarter will provide 4 minutes of
vacuum time. The total time can always be changed by adding or subtracting time. If the operator would later
decide to increase the cost of the unit to "2" quarters, the 2 dip switch would need to be in the on position (all
others off) and the time dip switches would still be 3.2 and .8 dips selected for 4 minutes. Timer is non
accumulating so "coins to start" setting is just to make the machine come on time and "time" is total time
regardless of coins to start. Time in minutes dip switch settings:
0.2 = 12 seconds
0.4 = 24 seconds
0.8 = 48 seconds
1.6 = 96 seconds
3.2 = 192 seconds
6.4 = 384 seconds

Machine Operating Instructions:
1) Read safety instructions on previous pages.
2) Insert coins (or bills) to start.
4) Using increase or decrease buttons select desired pressure.
5) Apply chuck to tire valve stem and fill to desired pressure. NOTE: For best results, remove valve stem covers on all
tires before depositing money.
6) Hang hose up when finished.
How Does Digital Air Work?
When the compressor is running, the machine will dispense air out the chuck. When air dispensing stops, the
system is searching for back pressure from the tire. Once back pressure is sensed, the machine will continue to
dispense air out the chuck until the tire is filled to the programmed pressure. If the digital air machine cannot fill a
low tire, the tire probably needs serviced.
Maintenance:
•All servicing of machine should be conducted by an authorized service representative!
•Periodically inspect hose, chuck, and chuck washer for wear or fatigue.
•Every month remove filter from compressor and clean.
•Periodically inspect electrical wires and connections for wear or fatigue.
•Clean canister with a stainless steel cleaner as needed.
•Decals can be cleaned with mild soap and water.
•Replacement parts can be ordered through JE Adams or your nearest dealer.

DISCONNECT POWER BEFORE SERVICING OR TROUBLESHOOTING!
Troubleshooting:
REV 3-23-2212
Problem Possible cause Solution
Breaker inside fuse panel is not inthe onposition. Turnbreaker on.
No power to machine. Check incoming power line for voltage.
Machine power switchis not on. Opencabinet door and flip switch.
Loose connection. Check incoming power connection.
Air is leaking from unit somewhere.
Turn power off to unit, apply chuck to air
source with at least 30lbs of pressure and
listen carefully for leaks inside cabinet or air
hose. Replace faulty component if leaking.
If no system leaks, is compressor putting out
enough pressure?
If compressor cannot force air into tire, the
compressor may have exceeded its life span
and needs rebuilt (about 1000 hours).
Chuck washer is worn out?
Replace with special JE Adams PN 8533-
13CW.
Temperature is below freezing and condensation
off compressor has froze in air hose.
Remove air hose and chuck and bring into
warm area to thaw.
Wrong size breaker or other components running
on same circuit.
Install correct breaker for compressor and
make sure line is a dedicated power source.
Compressor or timer might be shorted out?
Isolate problem component and replace if
necessary.
ALWAYS DISCONNECT POWER BEFORE TROUBLESHOOTING!!
Unit is not powered.
Unit runs but will
not inflate tire.

REV 3-23-2213
WHEN PERFORMING MAINTENANCE OR TROUBLE-SHOOTING, TURN POWER OFF!
QUALIFIED PERSONNEL ONLY!
Check keycomponents to isolate failure:
Capacitor: it is possible the capacitor has
failed and will not start motor. Change if
necessary.
Timer: Verifyproper input voltage. Activate
timer. If no output voltage is present when
timer should be active, replace timer.
Coin mech: If using a mechanical coin
mech, remove the wires leading to the timer
from the coinmechand tap them together
one time for eachcoinnecessaryto startthe
timer. If machine starts, replace the coin
mech.
Fuse: some units containanin-line fuse.
Check this to make sure power is getting
through. Replace if necessary.
Is source water turned onand not frozen?
Turnonwater to system and make sure
temperature is above 32 deg.
Is water solenoid getting power from timer? Ifgetting power from timer, replace solenoid.
Unit will not start
Possible component failure
Unit will not dispense
water (water
machines only).

Caution! -lethal voltage is present in all compressed air vending machines. Repair should only be attempted by trained
technicians. Note -Tests should be performed in order for proper diagnosis.
1.00 Check for loose connections:
Loose or broken wires can cause misleading symptoms. Check all connections before
proceeding.
2.00 Check AC power:
The pressure regulator circuit board and solenoids operate from a 24VAC power transformer.
The LCD display should have white LED back-lighting and the unit should indicate a 32 psi set
point and 0 psi during idle mode. If the display fails this check, the board is most likely not
receiving 24VAC power. If power is present at the 0.250” tab terminals, replace the digital
pressure board and/or display.
3.00 Adjust set point :
Adjust the set point with the up and down buttons. The buzzer should beep with every
adjustment.
3.01 Potential faults if set point does not increment or decrement:
Loose or broken push button wires
Push button
Digital pressure board
3.02 Potential faults if the buzzer does not beep:
Loose or broken buzzer wiring
Buzzer
Digital pressure board
4.00 Read tire pressure :
With the compressor off, attach the air chuck to a tire. The display should indicate the tire
pressure. The buzzer should beep when stable pressure is detected. Note the pressure and
remove the chuck. Measure the tire with an accurate hand-held tire gauge. Compare the
two readings.
Note -stick gauges are notoriously inaccurate, use a quality instrument for this
procedure. Make sure a good seal is achieved for each measurement. Any air escaping
during this procedure will greatly affect accuracy. The test tire should be at 32 to 50 psi for best results.

4.01 Potential faults if pressure is not within a few psi of measured tire pressure:
Tire chuck
Leaks in fittings or hose
Loose or broken pressure sensor cable
Solenoid stuck open
Pressure sensor
Digital pressure board:
4.02 Potential faults if pressure is within a few psi of measure tire pressure:
Digital pressure board requires calibration
Faults listed under 4.01
5.00 Calibration :
Skip this step if tire accuracy is within acceptable limits.
Tools:
Michelin MN-12279 Tire Gauge recommended (displays pressure to 0.1 PSI
resolution).
Notes:
Make sure the compressor is off before entering the calibration mode and remains off
during the entire calibration process.
5.01 Press and hold the “PROGRAM” button on the digital pressure circuit board. After
approximately 2 seconds, the buzzer will beep and "CAL" will be displayed. Release
the button. The exhaust solenoid will be enabled for 2 seconds after which all of the
display segments will be turned on to allow for visual inspection of the display. After an
additional 3 seconds, the exhaust solenoid will be disabled and the display will show
the pressure in 0.1 psi increments (example "P 0.3").
Note -during the time that all display segments are enabled, the pressure
board is adjusting the pressure sensor input for 0 psi measurements. The
pressure displayed initially will include any previously calculated offset.
REV 3-23-22

5.02 Attach the air chuck to the tire until the unit starts beeping,
indicating that the pressure reading is stable. Remove the air chuck from
the tire (the captured pressure reading will continue to be displayed until
the chuck is attached to the tire again). Measure the tire pressure with the
Michelin tire gauge and press the up or down button so that the pressure
displayed matches the pressure measured with the Michelin tire gauge.
Note -Make sure a good seal is achieved for each measurement. Any air escaping
during this procedure will greatly affect accuracy. The test tire should be at 32 to 50 psi
for best results.
5.03 The calibration mode can be exited in one of three ways:
1) Pressing the PROGRAM button for less than 2 seconds will exit the
calibration mode without saving the new calibration values.
2) Holding the PROGRAM button for 2 seconds until the beeper starts beeping
rapidly will save the new calibration values.
3) The pressure board will automatically exit calibration mode if no button
is pressed or no change in pressure reading is detected for 60 seconds
and the new calibration values will not be saved.
Tire inflation/deflation
6.01 Deposit the required number of quarters to activate the compressor. Adjust the set point to
the desired tire pressure. Attach the tire chuck to the tire and verify a good seal is achieved.
The digital pressure board should detect the tire and begin the process.
The buzzer should beep several times when the tire pressure matches the set point.
6.02 Potential faults during inflation/deflation test:
Loose or broken solenoid wires
Current sensor cable
Leaks between compressor and manifold
Foreign debris in solenoid seal area
Solenoid
Weak compressor
Faulty over-pressure relief valve
Digital pressure board
