1. Turn T-handle (Figure 13, Item 2) on gauge (Figure 13, Item 5) fully counterclockwise.
2. Connect gauge (Figure 13, Item 5) to inlet fitting (Figure 13, Item 4).
3. Turn T-handle (Figure 13, Item 2) fully clockwise and read gauge (Figure 13, Item 5). This is the test pressure.
Pressure should be 190 - 210 psi (1,310 - 1,448 kPa). If overcharged, slowly open bleeder screw (Figure 13,
item 1) and discharge nitrogen to correct level.
Discharging
