3. OPERATING INSTRUCTIONS 
The Hallett applies advanced Crossfire Technology, yet is simple to operate. The 
automatic quartz cleaning technology has been designed to reduce, and in most 
cases, eliminate the periodic shutdowns necessary to inspect the cleanliness of 
the quartz. The only required maintenance is the replacement of the two UV 
lamps every 12 months (note - if you shut your system down for seasonal use - 
the lamp life will be extended)
