UV System Maintenance

performed at least every 6-9 months or during routine maintenance intervals. Fouling could occur if lamps are installed under
chilled water lines. Wipe clean or install optional shield.

UV
Lamp Replacement
Fresh-Aire UV® lamps are rated for either one or two years
germicidal effectiveness. The lamps will continue to glow
after they have passed their rated life span but their germ-
killing effectiveness diminishes with time so they must be
replaced on schedule for the system to function properly.
Contact your local dealer for replacement lamps.
Important!
Use only Fresh-Aire UV® replacement lamps. Use of replacement lamps from other manufacturers voids the warranty.
