The louvers which allow the flow of cooling air away from the irradiator must be of a light shielding design.

(For more information on safety considerations, see Chapter 1, “Safety.”)

RF Detector Mounting

Figure 7 illustrates the proper mounting of the RF Detector.

Figure 7. Fusion UV Systems RF Detector RF-1

One RF detection device must be installed for each light shield. The antenna should point toward the irradiator screen, which is the potential source of RF leakage. However, to protect the antenna from heat and UV light, it should be placed outside the light shield. It may “look” into the light shield through an existing opening, or one made for this purpose. The tip of the sensing cone should be at least two inches from the opening of the light shield.

The presence of metal surfaces near the detector may cause false readings; allow a maximum open area around the device.

The connection of the cable from the RF detector to the power supply is explained in Chapter 3, “Electrical System”.
