FRESH-AIRE Blue-Tube XL Commercial Germicidal UVC System Instruction Manual

FRESH-AIRE Blue-Tube XL Commercial Germicidal UVC System

INSTALLATION & MAINTENANCE

BLUE-TUBE XL™ is designed for installation into commercial air handling units and rooftop package units for the purpose of surface or airborne disinfection using ultraviolet germicidal irradiation. For maximum installation flexibility and cost-effectiveness, the UV lamps are mounted onto a framework of standard 0.5” EMT tubing (included). The remotely mounted weather-resistant power supply can withstand the wet environment found inside of air handlers or the exposed conditions of outdoor packaged air conditioning systems. The number and placement of lamps is determined by several factors including coil dimensions and condition or if airborne disinfection is desired. BLUE-TUBE XL™ has everything needed for complete installation in most AHU and RTU equipment.

IMPORTANT!

• Only qualified technicians should install this product*
• Install in accordance with relevant building codes
• Read instructions carefully including safety warnings

Note: Installation of this product by anyone other than licensed HVAC or electrical contractors voids warranty.

COIL MOUNT INSTALLATION

1.  Determine the dimensions of the coils or area to be irradiated.
2.  Use the Coil Sizing Reference to determine the number of lamps needed for proper coverage.
3.  Larger coils may require multiple Tubular Rack Kits

UV Lamp Configuration Guidelines

• Maximum germicidal effectiveness is within an 18” radius from UV lamp center axis
• The distance between UV lamp(s) and the irradiated surface should be between 6”-18”, 12” is optimal
• The distance between stacked UV lamps should not exceed 35”
• The distance between end to end UV lamps should not exceed 12”
• The distance of UV lamp ends to the edge of irradiated surface should not exceed 6”

NOTE: The configurations shown here represent typical UVC coverage for coil surface disinfection. Adding more lamps is acceptable and is recommended for airborne disinfection.

COIL SIZING REFERENCE

DUCT MOUNT INSTALLATION

System Configuration A: In-Line With Air Flow (pre-assembled parts are ready for this configuration)

1. Cut an access panel into the duct. If necessary cover high exposure areas with UV-resistant reflective tape or similar material.
2. If needed, loosen or remove hardware then cut conduit to fit duct.
3. Mount the frame-work into the duct using the self-tapping screws or optional mounting magnets

System Configuration B: Diagonal To Air Flow

1.  Cut an access panel into the duct. If necessary cover high exposure areas with UV-resistant reflective tape or similar material.
2.  Remove hardware then cut conduit to fit duct.
3.  Re-attach hardware in the configuration below.
4.  Adjust the angle of the mounting brackets so the UV lamps will cross the air-stream diagonally. Mount the frame-work into the duct using the self-tapping screws or optional mounting magnets

Assemble Conduit Framework

1.  Measure and cut tubing to length then slide on conduit/ lamp clamps (do not fully tighten bolts yet).
2.  Mount the L-bracket and tubing as shown. Mount L-bracket to air handler wall using screws or magnet (galvanized metal only).

Install UV Lamps
Snap UV Lamps into the Lamp/conduit Clamps. Be sure to clamp to the rubber lamp connector on one end and the ceramic lamp tip on the other end. DO NOT clamp onto the lamp glass. Use Black Nylon Zip-Ties to secure lamp cables to Blue-Tube XL components and/or supports.

IMPORTANT! Install in accordance with all state and local electrical and building codes. Proper voltage is automatically selected by the unit between 120–277 VAC Single Phase 50/60 hz. For 460 VAC use a step-down transformer.
IMPORTANT! An external power suppressor is suggested if power surges occur often.

Mount Power Supply
Mount the power supply in a location (inside or outside of the HVAC system) that is convenient for access to the main power supply and for connection to the UV lamps. The power supply is weather resistant and is suitable for mounting inside or outside of the air handler. An Optional Power Supply Panel Mount (part # TUVC-P) is available for mounting two or more power supplies.

1.  Use the supplied self-taping sheet metal screws to mount the power supply in place through the mounting holes on the sides of the base. It is recommended to use wire boxes or another sealing method to pass the power cord and lamp cables into the interior of the air handler for connections. We also offer an Optional 3/4” or 1” Cable Strain Relief
2.  IMPORTANT! Turn off main power before making electrical connections. Refer to the Electrical Diagram for proper connection of the power supply to the main power.
3.  An Optional Door Interlock Switch is available to prevent accidental exposure to UV Light. Interlock switches are mounted on the access panels and doors so the UV lights turn off when the entryway is opened.

Connect Lamps & Cables
Arrange cables as needed for installation. When UV lamps, power supplies, and cables are in place join the lamp and power supply cables by aligning the electrical pins and flanges on the rubber connectors and pushing them firmly together. When adding lamp extensions, 20 ft. is the maximum distance from power supply to the lamp.

Assemble Conduit Framework cont.
When needed, use the 12” Stand-off on the near side to create separation between lamps and coil or to suspend the lamps from the air handler ceiling, such as in a roof top unit. Mount the 12” Stand-off using self-tapping screws or by attaching a bracket magnet.

Sight Glass Installation

1.  The sight glass allows safe viewing of the UV light system when in operation. Find a suitable location such as a door to the HVAC system for the sight glass.
2.  Drill a 1” hole and press the base of the sight glass through it.

Power-up System
Caution: UVC light that can cause Serious Eye Burns and Temporary Blindness, Ensure all access panels have been replaced and doors closed before powering- up the system. Turn on the main power then switch on the UV light power supply(s). Use the sight glass to confirm that the UV Lamp(s) is operating.

UV System Maintenance
Periodically wipe the UV lamps with a clean cloth or alcohol swab to remove any accumulated dust or dirt. This should be 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
Blue-Tube XL high output lamps are rated for 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.
