3. Keep the N2O needle valve at the maximum position. Close the O2 needle valve knob and then
slowly open the O2 needle valve. Observe if the O2 flow falls within 0.25 to 03 L/min when the
N2O flow begins. If not, repeat step 2 until the requirement is satisfied.
4. Keep the N2O needle valve at the maximum position. Turn O2 flow to 3 L/min and observe N2O
flow. If the N2O flow is less than 8.3 L/min, turn the N2O resistor on the ORC anti-clockwise with
the flathead screwdriver until the N2O flow is 8.3 L/min. If the N2O flow is more than 8.3 L/min,
turn the N2O resistor on the ORC clockwise with the flathead screwdriver until the N2O flow is
8.3 L/min.
