Warranty
The warranty on the LN2 TX is described in the warranty state-
ment included with the device.
Maintenance
No maintenance is required on the LN2 TX. There are no mov-
ing parts to wear out.
Troubleshooting
If the flow rate is low, make sure that the gas supply valve is fully
opened and that supply pressure is between 22 and 55 psi.
If the gas supply meets the above requirements, the orifices in the
suction head at the inlet of the LN2 TX may be partially blocked.
• To clean the orifices, disassemble the suction head by
removing the three screws and separating the two halves of
the unit.
• Remove the o-rings and insert inside the unit.
• Clean the orifices in the outlet end of the insert as required.
• Reassemble the unit in the reverse order of disassembly,
making sure that the orifices on the insert face the outlet
end of the suction head.

The discharge end of the LN2 TX is shown in Figure 8
Figure 8, Discharge end of LN2 TX
Place the discharge end of the LN2 TX as shown in Figure 9. The
LN2 TX is equipped with a phase separator to minimize splash.
The discharge end can be placed in the bottom of the receiving
container, but flow will be reduced and splash will increase. The
transfer will be more efficient if the phase separator is suspended
above the liquid level in the receiving container.

container
Once both ends of the LN2 TX are placed in their respective con-
tainers as described above, open the gas use valve on the liquid
cylinder supply.
Liquid transfer will begin as soon as the transfer device is cooled
to liquid temperature. Transfer will continue until the originating
container is empty, or the suction end is removed from the liquid.
When the transfer is complete; close the gas use valve on the
liquid cylinder supply.
The rate of transfer is dependent on the flow rate of the gas sup-
ply. The higher the pressure, the higher the flow rate up to a
point. Supply pressure in excess of 50psi will reduce the transfer
rate due to liquid flashing to gas.
