Nozzle Change Out Procedure
1. Remove the dosing head heater.
2. Insert the nozzle tool into the nozzle area until the tool connects with the nozzle (Image 1).
3. Remove the nozzle with the driver in a counter-clockwise direction. Remove.
4. Once the nozzle is removed, place the new nozzle or cleaned nozzle into the nozzle tool and insert in a
clockwise direction (Image 2).
CAUTION: The dosing head heater may still be in operation. Do not expose skin to prolonged contact with the
dosing head heater. The maximum temperature of the dosing head heater is 150ºF (65ºC).
IMPORTANT: Always perform nozzle change out procedures before introducing LN
2
into the UltraDoser unit.
Failure to do so may cause the nozzle to unthread and fall out.
IMPORTANT: If the nozzle does not loosen easily, drain the UltraDoser unit through the SRV / drain plug and
warm up nozzle with a low voltage heat gun.
