6. Now select the desired temperature with the Scroll Keys (
key; observe the Digital Readout as the Set Temperature increases (or decreases) in 1° and
then 10° increments as the key is held. Press the Select Button when complete.
NOTE: The minimum temperature is 149° C (300° F) and the maximum temperature is 482° C
(900° F).
7. Next, press the Scroll Down Button ( ) once. The Blower Speed LED will now be flashing.
8. Press the Select Button and select the blower speed (1-9 or 5-20 SLPM) by using the Scroll

where the bottom of the vacuum cup is flush with the bottom edge of the
nozzle.
11. Hold the handpiece vertical to the PCB.
12. Lower the nozzle:
a) To an approximate distance of 1mm (.040") above the PCB when using a
