3.0 Operation
3.1 Switch Functions
Reduces the set pressure
Increases the set pressure
Displays an alternative unit of
measurement *
This switch can be programmed to operate
in one (1) of the following modes :
Default Unit Mode
Pressing and holding the Switch will
momentarily display an alternative unit of
measurement. When you release the
switch the display will immediately revert
back to the default unit of measurement.
The pressure can only be set in the default
unit of measurement.
Selectable Unit Mode
Pressing and releasing the Switch will
display an alternative unit of
measurement. The pressure can be set in
any of the units of measurement.
* The units displayed on each machine will vary
depending on the software that has been
requested.
The ʻ ʼ Switch discharges up to five (5)
bursts of air. Used when the pressure in
the tire is less than 3psi, 20kPa or 0.2 bar.

WARNING
3.2 Inflation & Deflation
3.2.1 Set the desired pressure, refer to Section
3.1 for the function of each Switch.
3.2.2 Connect the hose to the tire, ensure the

(5) times. This will continue until the hose
is disconnected, during this time the
keypad will be disabled.
Ensure that the product is
connected to the correct power
and air supply, refer to rating
label and general specifications.

8.0 Compressed Air Systems
The information in this section is designed to provide
some basic information about compressed air
systems and the use of Digital inflation equipment.
Compressed air systems contain oil and water, it is
important to filter and drain these from the system.
The water is generated by condensation and oil can
be carried into the line from the compressor. A basic
system is illustrated below. The components of this
system are as follows:
1. Air Compressor
2. Air Receiver Tank
3. Valves
4. Filter & Regulator
5. Condensate Drain (Water Tap)
6. Digital Tire Inflator
!WARNING
!WARNING
!CAUTION
!CAUTION
To avoid the risk of personal
injury, especially to the eyes, face
or skin DO NOT direct the air
stream at any person/s.
To avoid equipment damage,
never exceed the manufacturers
maximum inlet pressure of 150
psi, 1035 kPa or 10.3 bar.
This equipment is not intended
for use by children without adult
supervision.
This equipment has NO user
serviceable parts. Only trained,
experienced repair personnel
employed by an authorised
service agent should perform
service to this equipment.

!WARNING
!CAUTION
Each system and installation of Digital inflation
equipment is different however it is imperative with
any system that the drain valves (No.3) are opened
routinely to remove water that has been collected.
Immediately prior to the tire inflator (No.6) a regulator
(No.4) should be fitted. This should be set to 10 psi,
70 kPa or 0.7 bar above the maximum set pressure of
the unit. This will prevent excessive pressure being
supplied to the unit and the resulting error message
ER4. Refer to Section 4.0 Troubleshooting.
Also prior to the tire inflator a filter (No.4) should be
fitted. This filter should remove all solid materials
such as scale caused by corrosion inside the pipe
and reservoir. Contaminants may have an adverse
effect on the internal components of the system due
to blockage and corrosion.
Ensure that the product is
connected to the correct power
and air supply, refer to rating
label and general specifications
If this equipment is being installed
on a retail petroleum site
consideration must be given to
the requirements of Australian
Standard AS/NZS2430.3 or the
relevant Hazardous Area
standard for your region.
