Changing Settings: Quick Programming Method
Digital control panel/timer unit:
Unit may be programmed when received depending on information given
at that the time of order.
To program, follow the instructions below:
1. Turn unit off.
2. Hold coin switch lever in the down position.
3. Turn unit on.
4. Units display “t4” after s short boot up sequence.
5. Release coin mechanism switch lever.
6. As soon as coin mech switch lever is released, "No PU" will appear
(number of pulses) for a short time and then will automatically scroll to the
input quantity. The unit now displays a two digit number. This is the
minimum number of coins to make the unit engage for the programmed
time. “00” unit is free air, 01 for 1 coin, 02 for two coins, etc. Adjust by
using + or – buttons on the control panel. Note: vacuum and air
compressor are not able to be priced or timed at separate values.
The programmed price gives you the programmed time
regardless of function chosen.
7. Press i button to continue: Unit now advances to "Dur" (duration or
amount of time per coin) on the display and will automatically scroll to the
amount of time in seconds per coin. Adjust this amount by using + or –
buttons. Example: For 4 minutes of vend time for $ 0.75 – using the plus
or minus button set the duration to 80. This means 80 second per coin
(Quarter) for a total of 240 seconds or 4 minutes running time. (note: this
parameter will not show up if the unit is set to free vend, “00”, in the
previous step).
8. Press i button to continue and unit will display "COnn" (compressor) for a
short time and then automatically scroll to the compressor operation
mode. Choose which mode you would like by using the +/- buttons; "no" =
none or no compressor, "denn" = on demand, and "cont" = continuous.
"Cont" is recommended as it seems to cause the least amount of
confusion to the end user.
9. Press i button to continue and unit will now display "nnod" which is a
setting for a modem (Y or N). Most applications will not have a modem so
this will need to be set to "N" (no).
10. Press i button to continue and unit now displays "End".
Turn unit off for 10 seconds and the back on. Now controller has the new
parameters.
Counter:
To access the counter:
In normal operation mode, press "i" button and just after the beep press the
"minus" button (you must be quick - may have to do this 2-3 times).
3/30/2011 5

This unit has two counters:
The first one is a non-resetable 8 digit number shown in two steps: CnH 0000
and the CnL 0000.
When pay air mode the counter shows the number of coins put through the
machine (not the number of vends).
When free air mode the counter shows the number of vends.
Changing settings – advanced programming.
Before beginning, most domestic applications will require “PSI” rather than
"BARS" at the gauge and on the display. These settings are factory set at
JE Adams. Only access these settings if absoltuely necessary and write
down settings before you change them.
1. Turn power switch to off.
Hold coin switch lever in the down position.
2. Turn power switch to on, and wait for first audible “beep.”
Just after first “beep” press (“+”) button followed by
the (“-” ) button. “Prtr” is shown on the display.
(if Prtr is not displayed, turn unit off and try again)
3. Release the coin switch lever and
press “ i ” button once, “T-4” blinks on display and
will then disappear.
4. “1 Un” is now shown on the display for a brief moment
and will automatically scroll to the setting.
At this step, set the pressure unit for the gauge.
"PSI" or "BAR" are the options. Choose PSI for most
applications by using the + or - buttons on the control panel.
Press “i” button to continue
5. “2 Un” is now shown on the display for a brief moment
and will automatically scroll to the setting. "PSI" should
be shown, if not change to PSI.
Press “i” button to continue

6. “dE” is now shown on the display for a brief moment.
At this step, set the default tire pressure, value which
is factory set at 32 PSI. Use + or - buttons to set.
Press “i” button to continue.
7. “LS” is now shown on the display. This is typically
set to 70 PSI which is the maximum pressure value.
Press “i” button to continue.
8. “nº PU” is shown on the display for a short moment and
then a two digit vaule is displayed. This represents the
number of coins to activate machine.
9. 00 is for free vend, 01 for one coin, 02 for two coins,
and so on. Choose by using + or - buttons.
Press “i” button to continue
Note: vacuum and air compressor are not able to be priced or
timed at separate values. The programmed price gives you the
programmed time regardless of function chosen.
10. “Dur” is now shown on the display which represents
the amount of time per coin in seconds. If
machine is set to “00” free vend, this option
will not be present. Set time per coin by using “–“ or “+” buttons.
Press “i” button to continue
11. “Conn” is now shown for a brief moment and then the
setting. Leave this at "cont". See quick programming
section of manual for full explanation.
Press “i” button to continue
12. “nnod” is shown on the display which is for the modem setting.
3/30/2011 7

Most machines will not have a modem so choose "no."
Press “i” button to continue
13. “End” is shown on the display
This indicates the setup is finished.
Turn tire gauge off, wait 10 seconds minimum before turning on.
Next time the tire gauge is on, it will work with the new settings
Operating Instructions:
Flip toggle switch to desired function, then insert coins or bills to start
machine.*
If other function is selected other than original selected item, unit will
switch to that function.
Once service is used, hang up hoses.
*NOTE: vacuum and air compressor are not able to be priced or
timed at separate values. The programmed price gives you the
programmed time regardless of function chosen.
Maintenance:
Filter bags should be taken out weekly and shaken out. Also it might be a
good idea to keep a new set of bags on hand so that once a month or
longer you can take original bags out and wash them.
Check vac hose and air hose for cracks on a weekly basis.
Clean canister with a stainless steel cleaner as needed.
Every month, remove filter from compressor and clean.
Check vac motor brushes approx. every 3 months for excessive wear.
Motor brushes should be changed if they are shorter than 3/8”.
Disconnect power before doing this!!
No lubrication required on vacuum motors or air compressor.
All servicing of machine should be conducted by an authorized service
representative.
