Fusion F300S - Manual (Page 19)

Installation, Operation, and Maintenance Manual # 509252 Rev R 19
The following table lists the various irradiator models manufactured by Fusion UV
Systems, and describes their high-level differences.
Reflector and Cavity
The top of the reflector contains two rectangular slots which admit microwave energy
into the cavity. The slots are fed by one 1800 W, 2450 MHz magnetron located in the
top half of the lamp enclosure and connected to the cavity by a waveguide launcher.
Lamp Bulb
The lamp bulb ( Figure 3 ) is made of quartz and has a tapered shape which optimizes
its UV, thermal, and microwave properties. The short quartz stubs at either end of the
15.3 cm (6") bulb provide mechanical support for quick mounting into spring-loaded
receptacles at the cavity ends. They are not electrodes and have no electrical function.
Figure 3. Lamp Bulb
Access to the cavity for changing the bulb or routine cleaning of the bulb and reflector
is easily accomplished by removing the screws which secure the screen assembly to
the bottom of the lamp. This procedure is explained in detail in
Chapter 6,
“Maintenance” . The fine mesh screen must be intact and firmly secured to the lamp if
the system is to work properly and safely. The RF leakage interlock automatically
shuts the system off if excess microwave energy passes through the screen.
