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 (see
Figure 43 ). For the
I310M/I311M and I310M-D/I311M-D, the pressure should be 447-596 Pa (1.8-2.4”
H
2
O) with respect to outside (ambient) air.
For the I310MB irradiator (modular blower), pressure should be 447 - 822 Pa (1.8 to
