SAFETY INSTRUCTIONS Please read the safety and installation instructions carefully to help ensure a correct and SAFE installation of the Aprilaire Ultraviolet Germicidal Lamp. WARNING Ultraviolet light is harmful to eyes and skin. Never look at light produced by this lamp. Shut off power to lamp before servicing. Electrical shock from 120 - 277 VAC may cause serious injury. Shut off power before starting installation and do not turn power back on until complete. Sharp edges may cause personal injury. Use care when cutting and handling sheet metal. Lamp may cause personal injury in the form of burns or cuts. Wear protective gloves and safety glasses when handling lamp. To prevent burns, shut off power to lamp and allow to cool for several minutes before servicing. If lamp is broken, refer to lamp disposal section of this manual. CAUTION UV light can cause color changes or structural degradation of plastics, rubber, paper, and other non-metallic materials used in the HVAC system. • Install lamp in location that prevents exposure of plastics, rubber, paper, and other non-metallic materials to UV light, or shield such materials with aluminum tape, sheet metal, or metal conduit. • Shield electrical wires that receive direct or reflected UV radiation with aluminum tape, sheet metal, or conduit. • Install lamp at least 8 inches away from equipment or components made with UV resistant plastic. If equipment or components are not made with UV resistant plastic – or if the UV resistance of the material is unknown – shield with aluminum tape or sheet metal. Water may damage lamp. • Install lamp at least 3 inches away from evaporator coil. • Do not install lamp below a humidifier or any source of water. © Research Products Corp. II. APPLICATION Models 1952, 1953, and 1972 Aprilaire Ultraviolet Germicidal Lamps are designed for the treatment of evaporator coils used in rooftop HVAC air handling units or in larger split systems used in the light commercial market. The UV germicidal light emitted from the lamps will kill microorganisms growing on evaporator coils and drain pans and prevent further growth. The units use 120 -277 VAC / 60 Hz / single phase power, and are designed for continuous lamp operation. External Mount Rooftop Units Model 1952 24” Rooftop Unit Model 1953 32” Rooftop Unit The External Mount Rooftop Units incorporate a NEMA 4 enclosure for protection against the elements. These units are intended primarily for installation on rooftop air handling units. Internal Mount Rooftop Unit Model 1972 Rooftop Unit, Internal Mount The Internal Mount Rooftop Unit is intended primarily for rooftop applications in which it is preferred to mount the unit entirely within the air handler rather than penetrating the outer cabinet. This unit is 18” in length and is mounted using supports supplied with the lamp. III. INSTALLATION NOTES FOR ALL MODELS • The installation should be done by a licensed professional trained in the installation and servicing of HVAC equipment. Unit must be installed in accordance with all applicable national and local codes. • Read all safety instructions at the beginning of this manual. Failure to do so could lead to personal injury and/or equipment damage. • Read the installation manuals for the equipment on which the lamps are being installed for additional information and warnings. • In cases where fungi and/or bacteria are already present on the evaporator coil, it is recommended that a qualified HVAC service technician clean the coil before the installation of the UV Lamp. Because the Aprilaire Ultraviolet Germicidal Lamp quickly kills fungi and bacteria, there could be an initial period of temporarily increased levels of airborne decay products if the coil is not cleaned before installation. • The tools and equipment required to complete this installation include: Drill, drill bits (3/32 in. & ‘Unibit’), holecutter (2 in.), Phillips screwdriver, #10 nut driver, tape measure, sealant, aluminum tape, multimeter with clamp-on ammeter, alcohol & wipes, and safety glasses. Some installations may also require wea...
