TOP OFF AND NITROGEN PURGE CYCLE COUNTER
NTF-230 will total the number of Top Offs and Nitrogen Purge Cycles performed.
1. Press and hold + and - buttons simultaneously until unit beeps.
2. Press + or – button.
3. First displayed number shows thousands of Top Offs.
4. Press + or - button. Hundreds, tens and ones of Top Offs will be displayed.
5. Press + or - button. Thousands of Nitrogen Purge Cycles will be displayed.
6. Press + or - button. Hundreds, tens and ones of Nitrogen Purge Cycles will be displayed.
7. Press + or - button to exit counter mode.
OVER PRESSURE SETTING (OPS) AND NITROGEN PURGE CYCLES (N2P)
The Over Pressure Setting can be used to improve the purity of the tire(s). The Over Pressure
Setting over inflates the target pressure on the first inflation by the OPS amount. For example,
if the OPS is set at 5 PSI and the initial target pressure is set to 30 PSI, then the
Nitrogen Purge
Cycle will deflate to 3 PSI, inflate to 35 PSI, deflate to 15 PSI, then inflate to 30 PSI. Inflating to
35 PSI during the first inflation instead of 30 PSI will result in higher nitrogen purity in the tires.
The number of Nitrogen Purge Cycles can be set. One Nitrogen Purge Cycle consists of deflating,
inflating, deflating to 50% of the target pressure, and inflating to the target pressure. This
entire process can be automatically repeated by changing the number of
Nitrogen Purge Cycles .
This is another method to obtain higher nitrogen purity in the tire(s).
1. Turn POWER switch on.
2. Press N
2
button once.
3. Press + or – buttons to change the Over Pressure Setting.
4. Press START button to save the Over Pressure Setting.
5. Press N
2
button twice.
6. Press + or – buttons to select desirable number of Nitrogen Purge Cycles.
7. Press START button to save the number of Nitrogen Purge Cycles.
When unit is turned off, it will save the changed settings until they are changed again.
NOTE: If the number of Nitrogen Purge Cycles is set to 0, the unit will perform inflations only.
BATTERY CHARGING
NTF-230 is powered by an internal 12VDC battery. Charge the battery for at
least 5 hours prior to first use. Battery charge level is displayed immediately
upon unit powering. HI indicates that battery is charged. LO indicates low
charge and battery needs to be recharged. Plug battery charger in 110VAC
wall outlet and insert plug into battery charging port. Unit can be operated
during recharging process. Typical recharge time is 3-5 hours, depending on
battery condition.
Note: While not using the NTF-230 to fill tires, generate Nitrogen and increase the
Nitrogen pressure in the internal storage tank by turning the panel valve to
STANDBY.
Note: While using the NTF-230, the automatic drain feature of the filters may
activate to remove excess water and oil. This is normal with the standard operation
of the unit.
