SAFETY CONSIDERATIONS
Understand the signal words DANGER, WARNING, and CAUTION. These words are universally used for overall safety.
DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies
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
