Before leaving the building, check the current weather and wind conditions. Take the balloon and parachute and proceed to the inflation building. Turn on AC Power to the hydrogen/helium when entering the building.
The light indicating gas flow should be on. If it is not, check the emergency cutoff switch on the free-lift inflation nozzle. It should be on the “Off” position (Figure 1.2).
Figure 1.2—The red switch is the emergency cutoff valve for the hydrogen. (a) The switch is in the “On” position. (b) The switch is in the “Off” position. Valve must be in the “Off” position for the gas to flow.
Open and remove the balloon from the plastic bag. Unroll the balloon onto the table, but . Handle the balloon by the neck. Use the plastic bag that originally held the balloon if needed.
Place the balloon neck over the inflation nozzle and secure with retaining clip. Make sure the appropriate weight is placed on the inflation nozzle before inflating. Careful consideration should be taken regarding precipitation, high winds, icing, and/or surface obstacles, when deciding how much weight to choose. Note that the nozzle apparatus is 1400g.
