Other Instructions:
Upon recieveing your Unlimited Oxygen unit, remove it from the shipping carton. Give the unit a thourough visual inspection checking for cracks or other shipping damage. Open the filter access door and check the filter. If damage is noted, please notify Unlimited Oxygen. If no damage is noted, plug the unit into a wall outlet and turn it on. Listen for any strange noise. The unit should run quietly. A light breathing sound can be heard and is normal. The flow indicator ball should rise to a level and can be adjusted by turning the flow knob. Never run the flow above the prescribed flow rate. M5 is 5 lpm, M10 is 5 lpm, M15 is 8 lpm and the M20 is 10 lpm. Running the flow too high can cause the oxygen purity to drop to levels that wont run your torch.
