General Specifications
Guidelines
In order to provide a trouble free operation it is necessary to
connect the power supply from the main switchboard with a MAX
3amp fuse/RCB protection device.
The circuit breaker should be marked as the disconnecting device
for the equipment.
The compressor producing the air should have the necessary
water and dirt filtration, to minimise accumulation of debris at the
inflator line filter strainer. There must be no oil mist in the air inlet
line.
For efficient tyre inflation, ensure that the air supply is 14.5 psi, 1
bar or 100kpa above the intended maximum inflation range.
Inside installations
Use 3 pin connecting plugs or 2 pin + Earth with the Earth Ground
wire installed on electrical infrastructure.
The unit is designed to run with the earth connection installed.
"According to Class 1 - Basic insulation in conjunction with
protective Earthing"
Calibration & Accuracy
The accuracy of our digital units when released from our factory is
that:-
The maximum permissible error (MPE) = 0.08 bar
Each unit, before release, is checked and calibrated on test
equipment that has accuracy traceable to a UKAS Laboratory No.
0221 referenced to certificate 0029346.
Emergency Stop
Stop the inflation / deflation cycles by pressing any button on the
front panel or by turning the unit off.
Battery Charging
It will take 3 hours from flat to full battery storage.
Charger LED Status:
Orange—Fast Charge
Yellow—Top Off 90% Full
Green—Fully charged with trickle charge
Approximate hours from full charge of Continual Tyre Inflation and
Deflation = 24 hours.
Approximate hours of Continuous Machine Idle Time = 140 hours.
Do Not leave battery in an uncharged state as this will irreparably
damage the battery!

Air Inlet Port (Rp1/4
standard, 1/4 NPT on
request)
Outlet Port
System set-up instructions
1. Connect to air supply by screwing your chosen adaptor to the
Rp 1/4 fitting (1/4 NPT for US versions) into the compressed air
inlet port of the Filter Unit. Then connect your outlet hose to the
outlet port.
2. Connect the mains power lead to the C7 socket on the side of
the unit. The LED will change colour to ‘Green’ when the unit is
fully charged. This will take 3 hours from a flat battery.
Operation
1. Connect the output hose into customer pipework.
2. Turn the on-off switch to On, if the pressure in the system is
less then 8 bar the unit will start generating Nitrogen.
3. The unit will continue generating until a system pressure of 8
bar is achieved, the unit will stop until the pressure has dropped to
7 bar, and will restart, or the battery is exhausted, in which case it
will need recharging.
Nitrogen Purity Test Port
This is located on the top of the unit and is designed to identify the
purity of Nitrogen being produced by the machine. To identify the
purity of Nitrogen being produced ensure the unit is turned on
then remove the valve cap and push the connector on a PCL
Nitrogen Analyser unit (N2A001) which will automatically give you
a purity readout.

Test Point
Calibration & Accuracy
The accuracy of our digital units when released from our factory
is that:-
The maximum permissible error (MPE) = 0.08 bar.
Service / Maintenance
There is no requirement to service the following items:
1. Pressure Transducer
2. Electric Control Board
If these are faulty they can only be
replaced by a competent person.
Please refer to an Authorised
dealer.
Periodically
• Check the hoses.
• Check the tyre connector.
• Remove air input supply and tyre hose from the head.
• Check the Filter Indicator and replace filters if required.
Working safety instructions
Since the unit is not explosion-proof, the device should not be
installed in areas where explosions are possible. Consideration
must be given to the requirements relative to Hazardous Area
Standards for your region or country.
The unit is designed and built to the relevant basic health and
safety requirements of the EC.
This product can be dangerous if used
improperly. Children should not be
allowed to use this equipment, as
incorrect setting can allow tyre to be
over inflated and a subsequent tyre
burst/explosion can occur!
Each person who is involved with installation, start-up,
maintenance and the operation of the unit must read and
understand the complete operating manual.

Instructions for changing the
filter elements on the integral
Domnick Hunter filters.
When the white indicator ‘spot’ on the front window inside the
unit turns blue the filter elements need replacing. The average
lifespan of the filter elements is 600 working hours.
If the filter elements are not replaced
when the indicator turns blue then the
membrane system is liable to be
damaged.
Depending on the amount of ozone and
moisture coming from the compressor
this lifespan can increase or decrease.
Ensure air connection to the generator
unit has been removed or shut off before
attempting to remove filter bowls.
1. Unscrew the top bowl by screwing the top half of the housing
anti-clockwise until the bowl can be removed.
Filter Change
Indicator
2. Inside the top half bowl should be the ozone filter which is
black in colour. This can simply be pulled out with a small
amount of pressure.
3. Replace this with a new filter (part number: N2S43)
4. Screw the top bowl back into position, ensuring the bowl has
clicked into place in the main housing.
5. Repeat the above process for the lower bowl, this contains
the secondary oil mist and moisture filter (part number:
N2S42).
6. When replacing the bowls you must ensure they are screwed
back in properly, with the two symbols aligning against the body
of the filter as seen in the images below.
