NOTES:
1. In performing the velocity profile test, the front row of velocity readings
(behind the window) must be taken with the thermoanemometer probe
positioned perpendicular to the window with the probe head facing the
window.
2. Velocity readings for the middle row(s) and rear row must be taken with the
probe positioned parallel to the window.
3. In performing the calculated face velocity test, the exhaust transition collar
must be removed when taking air velocity readings with a thermal
anemometer probe. This is the manufacturer’s recommended method for
balancing the 10276 and 10451.
4. Direct Inflow Method is the manufacturer’s recommended method for
balancing the 10448-EBC 47.
