Air Pressure Verification

To test air pressure inside the irradiator, remove one cover plate screw and, using a magnehelic, place the end of the tube over the screw hole (Figure 30 on page 90). For the I300M, the pressure should be 447-596 Pa (1.8-2.4” H2O) with respect to outside (ambient) air.

For the I300MB irradiator (modular blower), pressure should be 447 - 822 Pa (1.8 to 3.3” H2O).
