UV Lamp Configuration Guidelines
• Maximum germicidal effectiveness is within an 18 inch
radius from UV lamp center axis.
• The optimal distance between UV lamp(s) and the
irradiated surface is 12 inch.
• The distance between stacked UV lamps should not
exceed 36 inches.
• The distance between end to end UV lamps should not
exceed 12 inches.
• The distance of UV lamp ends to the edge of irradiated
surface should not exceed 10 inches.
• The spacing guidelines above may not apply for all
applications. Use recommendations in Table 2 to select
appropriate kit based on coil size.
WARNING
Be careful of damage to equipment.
Ultraviolet light can cause color fading or degraded
structure of plastic material found in HVAC
equipment, avoid plastic material or equipment
with unknown performance against ultraviolet light
in the area of irradiation.
WARNING
UV Light Hazard.
Harmful to bare skin and eyes.
Can cause temporary or permanent loss of vision.
Do not look at the UV lamp when lighting is on. Use
indicator light on the ballast to check status. In
