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