Manual Model Nitrogen Tyre
Inflation System Operation Steps
-Use your tyre inflation gun (supplied separately)
tyre inflation gun
1.Connect air hose to your tyre inflation gun.
2.Lift the vehicle to avoid demage to the tyre due to the heavy vehicle
weight.
3.Remove the tyre valve core to exhaust the residual air from the tyre.
4.Inflate the tyre to 0.5bar/7psi with the tyre pressure gauge, then deflate
this 0.5bar nitrogen, this can improve the tyre nitrogen purity.
5.Re-Fit tyre valve core.
6.Inflate the tyre to the target pressure with your tyre inflation gun.
-Use your Clip-on deflator&inflator (supplied separately)

1.1 This Manual
Congratulations on selecting the nitrogen tire inflation equipment. Please read and familiarize
yourself with this manual before attempting to use this unit. Although this unit is very simple
to operate, the user will be working with high-pressure gas that must be handled with caution.
Compressed gas, if handled improperly, can result in serious or fatal injury.

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 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.
2.0Assembly
1. Unpack the carton and identify the components.

Description Quantity
Generator Unit 1
Hose with Couplers (1 meter/39 Inch) 1
Tire Fill Hose 1
Hose/Cord Storage Hook 1
Storage Tank Base 1
2. Install the 1provided Hose/Cord Storage Hook onto the Unit with the screws provided.
3. If using an optional storage tank, install the Storage Tank Base to the main Base Frame
with the provided hardware. Bolt the storage tank to the Storage Tank Base. Using the
provided 39 inch Hose with Couplers, connect the storage tank to the Outlet port located on
the reverse side of the Unit.
4. Connect a compressed air supply to the air inlet located on the Pre-Filter. This inlet
accommodates any ¼” nipples or air line fittings.
5. Connect the Tire Fill Hose to the outlet coupling located on the Unit.
6. Place the Tire Fill Hose on the hook.
Air Supply Caution
Compressed air should be supplied to the unit with the air dried to a dew point temperature
lower than the expected minimum ambient temperature. Typical dew point from a properly
sized refrigerated air dryer is sufficient (+40°F, 4°C). No water in liquid form should be
present. Inlet air pressure must be less than 217 PSI.

3.0 Preparation for Use
1. Plug unit power cord into the power source.
2. Connect a compressed air supply line to the inlet located on the Pre-Filter.
3. Turn the unit on by depressing the power switch. The Unit will immediately begin to
produce nitrogen. The nitrogen pressure gauge located on the Unit will indicate the nitrogen
pressure in the system and/or the optional external storage tank.
4. The Unit is ready for use when the nitrogen pressure gauge indicates a pressure of 130psi
(9.0bar/900kPa) or greater.
WARNING
To avoid the risk of personal injury, especially to the eyes, face or skin DO NOT direct the air
stream at any person(s).
CAUTION
To avoid equipment damage, never exceed the maximum inlet pressure.

NOTE:The filter bowls on the Pre-Filter assembly will accumulate water and oil when the
generator is in operation but drain automatically whenever the generator unit is powered
down or the filter housings are depressurized. It is recommended that the generator unit be
powered down when not in use to ensure filter bowls remain drained and conserve power/unit
life.
It is important that the filter elements are replaced on a regular basis (at least every 6
months) to prevent contaminates from entering the Unit.

5.0 Maintenance
5.1 Routine Maintenance
Change Filter Elements (Minimally every 6 months)
Caution: Perform Element changes only when system is depressurized.
1. Unscrew the housing from the filter head and drain off any oil in the housing into a suitable
container.
2. Remove and discard the used element. Replace the element with a new one of the
appropriate grade.
3. Screw the housing back onto the filter head. Do not over tighten. Housing is sealed with an
o-ring, so gently hand-tighten.
5. Repeat this process for both filters.
5.2 Routine Maintenance Schedule
Daily
1. Check for air and nitrogen leaks. Tighten or re-tape fittings as necessary.
2. Check that the inlet pressure is within recommended operating range.
Weekly
1. Clean unit as necessary.
Every Six Months
1. Replace filter elements.
