2. Connect the compressed Air supply to the Inlet of compressed air (A) located in the
regulator.
The inlet regulator should be set at 123PSI/8.5bar/850kPa
3. Connect the Hose with single clip-on open type chuck to AutomaticCnitrogen
inflation outlet (G) located in the unit
4. Connect the Manual nitrogen inflation outlet (I) located in the unit and the Nitrogen
inlet & Inflate ball valve (L) located in the Black Clip-on deflator&inflator by a Hose
with2quickcouplers.
5. Connect the Compressed air outlet (H) located in the unit and the Compressed Air
inlet & Deflation ball valve (K) located in the Black Clip-on deflator&inflator by
another Hose with 2 quick couplers.
6. Turn off the Deflation ball valve (K) and the Inflation ball valve (L).
7. Turn on the Compressed air outlet (H), the Automatic nitrogen inflation outlet (G)
and the Manual nitrogen inflation outlet (I).
8. Connect the power supply.
9. Press the power switch (F) to turn on the unit.The machine will produce the
nitrogen. The Nitrogen Pressure gauge (D) located in the machine will indicate the
Nitrogen Pressure in the internal Nitrogen Storage Tank.
10.Check that the Nitrogen Pressure in the internal Nitrogen Storage Tank is higher
than 72psi/5.0bar/500kPa. The equipment is now ready to use.
CAUTION
To avoid equipment damage. The compressed Air supply must be filtered by filter
(5micron) supplied separately which is to filter the oil and water in the compressed
air.
To avoid equipment damage, never exceed the maximum inlet pressure.
The filter bowls will accumulate water and oil when the machine is in operation and
require regular emptying by means of a manual drain at the base of the bowl (Turn
anti-clockwise to open and clockwise to close).
It is important that the filter elements are replaced on a regular basis to prevent water
and oil entering the machine.

4.0 Operation
4.1 Manual inflation by the Black Clip-on deflator&inflator
To increase the purity of the nitrogen in the tire the air must be removed.
4.1.1 Air extraction
1. Connect 0.7m hose (J) to the tire.
2. Turn the Inflation/Deflation control valve (N) handle to “Air extraction” position.
3. Turn on the Deflation ball valve (K).
4.1.2 Nitrogen inflation
1. Turn the Inflation/Deflation control valve (N) handle to “N2 Inflation” position.
2. Turn on the Inflation ball valve (L).
3. Tire pressure gauge will indicate the tire pressure when the Nitrogen inlet &
Inflation ball valve (L) turn off
CAUTION
If the tyre is still in position on the vehicle, it is paramount that all weight be taken off
the tyre by means of jacking the car up before deflating the tyre. The tyre must remain
without load until re inflation is complete.
4.2 Automatic Inflation
4.2.1 Topping Up of Nitrogen
1. A choice between bar, PSI, Kgf/cm2 and Mpa on the keypad is available by
pressing the white ‘C arrow key’before preferred choice.
2. Press the tyre pressure keys ‘∇’ or ‘∆’to set the final inflation pressure required.
3. Connect the hose to Tire, ensure the hose is connected securely. Nitrogen leaks will
cause a error message to be displayed.
4. If the pressure in the tire is higher than 15 psi, 100 kPa or 1.0 bar, the process will
commence.
5. When the top up cycle is completed, the unit beeps and the target pressure flashes
in the display.

4.2.2 Nitrogen Filling of the New Tire
1. A choice between bar, PSI, Kgf/cm2 and Mpa on the keypad is available by
pressing the white ‘C arrow key’before preferred choice.
2. Press the time setting key ‘∇’ or ‘∆’ for purge/vacuum cycle. The default value of
the machine is 20 seconds and the user can increase or decrease this setting according
to the tyre size.
3.Press the tyre pressure keys ‘∇’ or ‘∆’to set the final inflation pressure required.
4. Connect the hose to Tire, ensure the hose is connected securely. Nitrogen leaks will
cause a error message to be displayed.
5. Press the key ‘START’ for automatic purging cycle and nitrogen inflation to
commence.
6. When the top up cycle is completed, the unit beeps and the target pressure flashes
in the display.
4.2.3 To Convert Existing Mounted Air-Filled Tire to Nitrogen.
1. If the tyre is still in position on the vehicle, it is paramount that all weight be taken
off the tyre by means of jacking the car up before deflating the tyre. The tyre must
remain without load until re inflation is complete.
2. Deflate the tyre by removing the valve stem and once deflated, re-insert.
3. A choice between bar, PSI, Kgf/cm2 and Mpa on the keypad is available by
pressing the white ‘C arrow key’before preferred choice.
4. Press the time setting key ‘∇’ or ‘∆’ for purge/vacuum cycle. The default value of
the machine is 20 seconds and the user can increase or decrease this setting according
to the tyre size.
5. Press the tyre pressure keys ‘∇’ or ‘∆’to set the final inflation pressure required.
6.Connect the hose to Tire, ensure the hose is connected securely. Air leaks will cause
a error message to be displayed.
7. Press the key ‘START’ for automatic purging cycle and nitrogen inflation to
commence.
8. When the top up cycle is completed, the unit beeps and the target pressure flashes
in the display.
CAUTION
Should the inflation line detach from the valve during inflation the machine will
display the code ‘Err’.
Pressing the key ‘pause’at any time will stop the operation and repressing ‘pause’ will
start the operation.

5.0 The Pressure Calibration Procedures
To the automatic tyre nitrogen inflators, when the users found the inflator accuracy is
higher than 1.5PSI / 0.1bar / 0.01Mpa / 0.1Kgf/cm2, they can calibrate the unit by the
following methods.
1. Open the tyre nitrogen inflator,the below part is seeing on the top of the machine.
2. Turn off the power, take off the accessory (C) from the kick 4 and kick 5 of the
accessory (B), then insert it to the kick 1 and kick 2 of accessory (A).Turn on the
power.
3. Find a 14 inch tyre with the pressure inflated to 2.5bar/36PSI exactly,connect the
tyre to the Automatic nitrogen inflation outlet (refer to Section 2.0 Cntrol Layout)
located in the nitrogen inflator by the Hose with single clip-on open type chuck
inclouded (the customer also should use this hose to inflate tyres,or else will cause
measuring difference.)
4. Currently,the tyre nitrogen inflator LED (PRESSURE SETTING) will display the
pressure reading value,maybe 2.3 bar,2.4 bar,2.5 bar,2.6 bar or other values.Rotate the
knob on the accessory (D) with screwdriver, the reading on the LED will
changing,and adjust the LED display pressure into 2.4 bar/35PSI.
5. Deflate the tyre totally,and the tyre pressure should be 0 bar at this moment,then
connect the tyre to the the Automatic nitrogen inflation outlet (refer to Section 2.0
Cntrol Layout) located in the nitrogen tire inflator (or disconnect the tyre from the
nitrogen tire inflator,and let the Automatic nitrogen inflation outlet located in the
nitrogen tire inflator linked to the atmosphere.)
6. Now the LED will display 0.01 bar,0.02 bar,0.03 bar or any other digitals,then
rotate the knob on the accessory (E) with screwdriver.The reading on the LED will
change too,and adjust the LED display pressure into 0.01 bar.

7. Repeat the steps 3,4,5,6 three times.
8.Turn off the power,take off the accessory (C) from the kick 1 and kick 2 of the
accessory (A),then insert it to the kick 4 and kick 5 of accessory (B).Turn on the
power again.
9 .The calibration is over.
