To install the FRESH-AIRE UV TUV-RAD-100-DL Radiometer & Lamp Life Monitor, follow these steps:
1. Power Source: The power supply should be wired directly to the underside of the display. Plug it into a 120VAC outlet near the location of the display. Do not use the power supply to power additional devices. Make sure to power the radiometer with the provided power supply and not from another 24VDC source.
2. Display: Locate the display outside the AHU (Air Handling Unit) within a mechanical room or equipment closet. Ensure that the display is easily accessible and at an appropriate height to observe output readings, change settings, and silence alarms.
3. Sensor: The UVC sensor comes with a 20 ft cable. Do not extend or splice additional cable to the sensor cable. If you need to extend the length of the sensor, use the optional Repeater (TUVC-RAD-RPT) to extend it up to 10,000 ft. Mount the sensor to a center support in the coil, facing directly towards the UV lamp. Drill a 3/8" hole to pass the sensor cable through the AHU wall as close as possible to the radiometer display location. Protect the sensor cable from extensive UV exposure by shielding it with split plastic wire loom and securing it with zip ties.
4. Sensor Placement: Locate the sensor within the AHU near the center of the cooling coil. The sensor should be at a distance of 10-12 inches from the coil face for optimal output readings.
