2. INTRODUCTION
Robust, high reliability and modern design which is space-saving and lightweight. Touch screen technology with human touch recognition
software. Electronic pressure pre-set with additional four button memory function. Three modes, inate, deate and over pressure setting
(OPS) – which allows operator to set the machine to automatically seat the bead on new tyres whilst getting on with alternative work. The
inclusion of the nitrogen (N2) purge facility allows the unit to increase the e󰀨ectiveness of this increasingly popular tyre service. Red ashing
light, ashing screen and audio signal for end of cycle. Auto-start Ination. Ceramic sensor gives guaranteed accuracy to ± 0.5% of full scale

6.6.10. Display will show ‘Std’ if this is the required Application then exit ‘application mode’ by touching twice. To change to ‘tir’ or
‘N2P’ touch (+) And use to (-) change back to ‘Std’.
6.6.11. Conrm the application ‘Std’, ‘tir’ or ‘N2P’ by touching.
6.6.12. Display shows ‘APP’ exit the application by touching twice.
6.6.13. The QUBE will reboot into the desired application and will remain in this mode until an alternative application is required.
6.7. TYRE SHOP (TIR) OPERATION: INFLATION AND DEFLATION
6.7.1. Set desired pressure, by touching either or
6.7.2. Connect the hose to the tyre.
6.7.3. Automatic ination will commence to the set pressure, periodically stopping to display the pressure of the tyre.
6.7.4. If the pressure in the tyre is below 3 psi, 0.3 bar or 30 kpa, the process will not commence until is touched.
6.7.5. When the Set pressure is reached, the buzzer will sound and the display will show ‘END’ with the nal pressure. Red LED light will
ash.
6.7.6. Remove the hose from tyre.
6.8. TO ENABLE SETTING OF OPS
6.8.1. Touch and display will toggle ‘OPS’ and blank value.
6.8.2. Increment the OPS value between 0-29 psi, 0-2 bar, by touching and , to accept the value, touch
6.8.3. Display will revert to the Set pressure previously selected.
NOTE: The OPS value will not be applied when the tyre has a pressure of more than 3 psi, 0.2 bar.
To prevent the accidental use of OPS, the OPS setting is not retained after the machine is powered down.
Use of OPS:
The OPS value is added to the nal target pressure setting to give the Over Pressure.
Example:
A Final Set pressure of 32 psi, 2.2 bar is required with an OPS value of 15 psi, 1 bar. The tyre will now inate from at condition
only to the value of 47 psi, 3.2 bar.
Once the OPS value has been achieved, the unit will deate back to the desired set pressure.
For adjustments to Inators parameters please refer to your Distributor or Sealey.
WARNING! When using the OPS function, the sum pressure must not exceed the tyre manufactures maximum ination pressure.
6.9. N2 (N2P) OPERATION; INFLATION AND DEFLATION (TYRE TOP OFF)
6.9.1. Set desired pressure, by touching either or
6.9.2. Connect the hose to the tyre.
6.9.3. The process will not commence until is touched.
6.9.4. When the Set pressure is reached, the buzzer will sound and the display will show ‘END’ with the nal pressure. Red LED will ash.
6.9.5. Remove the hose from tyre.
6.10. TYRE PURGING (N2 CONVERSION)
6.10.1. Set desired pressure, by touching either or
6.10.2. Connect the hose to the tyre.
6.10.3. The process will not commence until is touched.
6.10.4. If the pressure in the tyre is below 3 psi, 0.3 bar or 30 kpa, the process will start but perform only one purge (since the tyre is
already at).
6.10.5. During the purging process the display will show the last pressure check point and the number of purging cycles completed when
deating.
6.10.6. When the set pressure is reached, the buzzer will sound and the display will show ‘END’ with the nal pressure. Red LED will ash.
6.10.7. Remove the hose from tyre.
NOTE:
• In N2 (N2P) Operation the QUBE will not commence ination until is touched for tyre top o󰀨 or for N2 Conversion.
• For N2 conversion of existing tyres the number of purge cycles is defaulted to 2.
• For at tyre purging the number of cycles is reduced by 1, as the tyre is already empty.
• The lower purge pressure limit is defaulted to the greater of 10% of the set pressure or 3 psi, 0.2 bar, 20 kpa.
For adjustments to Inators parameters please refer to your Distributor or Sealey.
6.11. N2 CONVERSION OF EXISTING TYRES
For normal use a Purity level of between 93% and 96% N2 is su󰀩cient for most road tyres.
If your N2 Generation source is greater than 97% then it is su󰀩cient to leave the default setting of 2 Purges.
For N2 Generation sources less than 97%, then to achieve the required N2 % Purity, consider adding additional Purge cycles.
For adjustments to Inators parameters please refer to your Distributor or Sealey.
The Final N2% concentration can be periodically checked using a N2% concentration meter.
6.12. USER INSPECTION MODE
It is possible to set the inator to act as a pressure gauge.
The display resolution is changed and can be used to reference the inator against a calibrated pressure source. The inator
automatic cycle is inhibited.
6.13. TO ACCESS:-
6.13.1. Touch and together.
6.13.2. The QUBE will beep but the display will not change.
6.13.3. Touch 5 times (if this is not undertaken within 10 seconds, the Inator reverts back to normal Inator mode).
6.13.4. Display will show the pressures to the minimum resolution: psi = 0.1 / Bar = 0.01 / kpa = 1 / kg/cm = 0.01.
6.13.5. Connect the hose to the tyre and the display will show the pressure in the tyre.
6.13.6. When complete, touch any button to return to the last set mode.
