Startup and Operation
When power is supplied, the green LED comes on,
indicating the system is functioning.
The red LED comes on when a pressure differential of
50% is reached, indicating that filter needs to be replaced.
Once a clean filter is inserted in the filter frame, the green
LED comes on.
Calibration
Each HEPAlert kit sensor must be set based on the
module and inlet size. Use the information in the following
steps to calibrate the setscrew.
1. Turn the setscrew clockwise to ensure it is in the fully
closed position. See Figure 14.
2. Based on the module and inlet size, twist the setscrew
counter-clockwise the prescribed number of turns from
the fully closed position. See Table 1.
Figure 15 shows the setscrew at the fully open position.
Figure 16 is a chart showing the pressure from supply
side of the HEPA filter.
