1. Locate the single row of holes at the front of the grille. Mark the 6

hole from

the side wall and subsequent test points every 9 holes until the number of

test points marked equals the width of the cabinet in feet (for a 4-foot

cabinet, for example, mark the first 4 points). Repeat for the opposite side,

as shown in Figure 6-11.

2. Start the Purifier, and let it operate for at least 5 minutes. Establish the

necessary correction factor to the thermal anemometer to ensure compliance
