■ Using 1Nos*10m/32.8ft standard Hose with single
clip-on open type Chuck for NITROGEN CONVERSION
1. Remove the tyre valve core, exhaust the tyre pressure to about
0.3bar/4psi, then refit the tyre valve core.
Also, the user can bypass the above but to proceed to step 2-6 below.
With the above operation, since the user removed the valve core
manually, so the exhaust time to 0.3bar/4psi will be shorter.
If the user bypass the valve core removeable process, as the valve
core still keep on the tyre, the exhaust operation to 0.3bar/4psi is
finished by the nitrogen tyre inflator automatically, so it will need a
long time.
2. Set final target pressure using the + and - buttons. The LCD screen will
show the target pressure.
3. Connect air hose to tire valve stem.
4. Push and hold the “FILL/PURGE” button for 2 seconds until the LCD
screen shows “N2P”.

1.3 Safety
General
The unit has standard process plant components and electrical equipment, which can
be hazardous to individuals unfamiliar with such equipment. It is the users’
responsibility to permit only trained and qualified process plant operators familiar with
the handling of compressed gases to operate this equipment.
Breathing
This unit is designed to produce high purity nitrogen from 95 – 99% purity. Nitrogen is
a colorless, odorless gas that will not support life. If released in an unventilated area, it
will displace the oxygen and can cause injury or death from asphyxiation.
CAUTION: Nitrogen gas represents an extreme asphyxiation hazard

6
when not handled properly. Product gas should not be vented or
otherwise discharged except through the normal piping system.
Appropriate signs should be placed in the area of the nitrogen system
warning of the hazards.

The inflator and LCD screen are programmed to switch off when unit is unused for 10
minutes. To restart inflator, press the "ON" or ( ) button.
5.0 Operation
Over Pressure Setting (OPS)
The OPS function momentarily "over-inflates" the serviced tires beyond the final target
pressure, by the amount set, and then deflates the tires to the final target pressure.
For example, with a final target pressure of 35 psi and an "OPS" setting of 10 psi,
when the "FILL/PURGE" or ( ) button is engaged to perform a "Top-Off," inflation
will commence and the display will flash the total sum pressure of 45 (35 psi target
pressure plus 10 psi OPS), then revert to displaying the actual tire pressure. The tire(s)
will inflate to the sum pressure of 45, the unit will beep twice, and then deflate to the
final target pressure of 35 psi.
To set the OPS value, press the "SET/MODE" or (i) button. The LCD display will
flash “OPS” and the current set value alternately. To change the OPS setting, press
the "+" or "-" buttons. Save your selection by pressing the "FILL/PURGE" or ( )
button. The OPS setting can be changed again whenever required.
To inflate without OPS, set the OPS value to zero.

9
To prevent the accidental use of OPS function, the OPS reverts back to its default
setting of zero each time the inflator is powered down.
WARNING
When using the OPS function, the sum pressure must not exceed the tire
manufacturer's maximum inflation pressure.
Nitrogen Purge Setting (N2P)
"N2P" represents the number of "purge" cycles, inflation and deflation of the tires, the
inflator will perform. To set the number of purge cycles, or N2P, press the
"SET/MODE" button. The display will flash “OPS” and the OPS set value alternately.
Press the "SET/MODE" or (i) button again and the display will flash “N2P” and the
N2P set value alternately. To change the N2P, press the "+" or "-" buttons. Save your
selection by pressing the "FILL/PURGE" or ( ) button. The N2P setting can be
changed again when required. N2P is preset to '"2" and can be set per above from "0"
to"9" purges.
Deflation Value Setting (DPS)
"DPS" represents the deflation value, or the value to which the tires will deflate, during
the first deflation cycle when the unit is in the "N2P" mode. DPS is preset, and defaults
upon power up, to 5 psi but is adjustable from 4 psi to 50% of the target pressure. All
subsequent deflation cycles, from the second deflation on, if more than one N2P
cycles are selected, will deflate the tires to 25% of the target pressure. This "multiple
deflation" value is not adjustable.
For example, DPS is preset to 5 psi, if it is not changed, and the unit is set to N2P
"1," upon activation the tire will deflate to 5 psi and re-inflate to the target pressure. If 2
N2P cycles are chosen, and DPS remains at 5, the tire will deflate to 5 psi, re-inflate to
the target pressure, deflate to 25% of the target pressure and finally re-inflate to the
target pressure. If DPS "6" is chosen, the tire will deflate to 6 psi on the initial deflation,
and deflate to 25% of the target pressure on any subsequent deflation cycles.
Hence, if a final target pressure of 32, an N2P setting of "2," and a DPS of 5 are
chosen, the tire will deflate to 5 psi, re-inflate to 32 psi, deflate to 8 psi (25% of 32 psi)
and finally re-inflate to 32 psi.
To set DPS, press the "SET/MODE" or (i) button. The display will flash “OPS” and the
OPS set value alternately. Press the "SET/MODE" or (i) button again and the display
will flash “N2P” and the N2P set value alternately. Press the "SET/MODE" or (i)

10
button a third time and the display will flash “DPS” and the DPS set value alternately.
Press the "+" or "-" buttons to change the DPS setting. Save your selection by pressing
the "FILL/PURGE" or ( ) button. The DPS setting can be changed again when
required. DPS is preset to 5 and ranges from 4 psi to 50% of the target pressure.
Auto-Start
The Auto-Start feature allows the inflation/deflation of tires to a preset target pressure
without having to press any buttons to start the process. When both "OPS" and "N2P"
are set at "0" , and the tire being serviced contain more than 5 psi, the serviced tire will
immediately begin to inflate/deflate to the target pressure upon connecting the tire fill
hose.
To permit the selective use of the "FILL/PURGE" or ( ) button, the automatic
start is disabled when the N2P or OPS settings are greater than zero.
5.1 Converting Tire to NITROGEN
1. Set the final target pressure, OPS, N2P and DPS settings.
For basic conversions OPS, N2P and DPS should be set at their "default" values
which are:
OPS: 0
N2P: 2
DPS: 5
2. Connect the tire fill hose to the tire valve stem.
3. Press and hold the "FILL/PURGE" or ( ) button for 2 seconds, Release the
"FILL/PURGE" or ( ) button only when "N2P" appears on the LCD display
screen.
4. When the cycle is completed, the unit will "beep" and the target pressure will flash
on the LCD screen.
5. Immediately disconnect the tire fill hose.
5.2 Topping-Off Tire with NITROGEN
1. Set the final target pressure.

11
2. When merely adjusting tire pressure (performing a "Top-Off), it is not necessary to
adjust the N2P or DPS settings. The OPS setting, however, should be at "0."
3. Connect the tire fill hose to the tire valve stem.
4. Press the "FILL/PURGE" or ( ) button momentarily (for less than 1 second).
The unit will inflate or deflate the tire(s) to the target pressure.
If OPS and N2P are set to zero, and the pressure in the tire is greater than 5 psi, it is
not necessary to press the "FILL/PURGE" or ( ) button, as the "Auto Start"
feature will automatically begin to inflate or deflate the tires to the target pressure.
5. When the top-off cycle is completed, the unit will "beep" and the target pressure will
flash on the LCD screen.
6. Immediately disconnect the tire fill hose.
