Safety Considerations - Field Controls CUV Series Manual

SAFETY CONSIDERATIONS

Understand the signal words DANGER, WARNING, and CAUTION. These words are universally used for overall safety.
DANGER identifi es the most serious hazards which will result in severe personal injury or death. WARNING signifi es
hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices resulting in minor
personal injury or product and property damage.
DANGER: Before performing maintenance or service on system, ensure power is de-energized prior to service.
Electrical shock can cause injury or death.
WARNING: UV light will break down plastic materials not rated for UV exposure.
• The unit must be mounted at least 20" from the above stated type of materials.
• If it is necessary to mount the unit in direct line of site of these types of materials, they must be shielded with
aluminum foil, metal foil tape or sheet metal.
WARNING: Before installing or servicing UV-Aire system, always turn all power OFF and have unit unplugged.
Electrical shock can cause personal injury or death. Never expose eyes or skin to direct UVC light from any source.
WARNING: The electrical supply circuit connected to this UV appliance shall be routed through an electrical
interlock switch placed on the HVAC system duct access panels and doors to prevent accidental UV exposure when
servicing the air ducts or equipment. Interlock shall break all supply conductors.
WARNING: DO NOT mount the UV Lamps outdoors. The magnetic mount power enclosure is designed to be
mounted indoor or with accessory mounting kit for outdoor locations.
WARNING: Never touch broken UV lamp or internal contents of UV lamp. The lamp contains mercury.
• In case of accidental exposure to internal contents of lamp, wash hands and any other affected skin area
with mild detergent. Remove affected clothing immediately. If skin surface is pierced, seek medical attention
immediately.
• If UV lamp breaks, clean and dispose of with the same care as a fl uorescent lamp.
• UV lamps must be disposed of in accordance with local, state and federal environmental disposal laws.
CAUTION: Equipment damage hazard. Ultraviolet light can cause color shift or surface degradation and sometimes
structural degradation of non-metallic components. Select mounting location that prevents exposure to plastic fl exible
duct components, polyurethane foam insulation material, rubber hoses, wire insulation, etc. If mounting options are
limited, items above should be protected with ultraviolet resistant material such as aluminum foil, aluminum duct tape,
or metallic shields or metallic tapes.
CAUTION: If you touch the glass of the lamp, you should wipe the glass clean with isopropyl alcohol and a lint free
wipe. If the lamp is not cleaned, the oil fi lm left on the glass lamp surface from your hand causes a reduction in the
light intensity.
CAUTION: Never expose eyes or skin to UVC light from any source.
• Looking directly at the UVC light may cause permanent eye damage or blindness.
• Never operate the UV-Aire Air Purifying System out of the plenum.
• Designed for a closed duct system. Do not mount near a supply or a return air opening.
• All duct openings in direct line of site of the UV light must be sealed with aluminum tape or equivalent sealing
methods.
CAUTION: UV Lamps are fragile. To prevent accidental breakage, handle UV lamp with care.
CAUTION: Resistance to UV radiation: Polymeric cabinet, structural, and current carrying parts and wiring which
are subjected to UC-C irradiance from a UV lamp system shall be shielded from or out of the line-of-sight of the UVC
light, or be constructed of a material that is capable of withstanding UVC exposure levels expected in the product
without degrading.
