UV INSTALLATION NOTES
• Unintended use of the appliance or damage to the housing may result in the escape of
dangerous UV-C radiation. UV-C radiation may, even in small doses, cause harm to the
eyes and skin.
• Appliances that are obviously damaged must not be operated.
• The appliance must be disconnected from the supply before replacing the UV-C LAMP.
• Doors and access panels bearing the ultraviolet radiation hazard label, which may have
UV-C SPECTRAL IRRADIANCE greater than 1.7 µW/cm, are provided with an interlock
switch to interrupt the power to the UV-C LAMPS for your safety. Do not override. See
figure 3.
• To comply with UL Standards, a magnetic switch must be deployed across all access
panels and doors that can expose an operator to more than of 1.7 µW/cm UV intensity.
• To comply with UL Standards, a UV-C Radiation Hazard label must be placed on any
doors or access panels which can expose an operator to more than 1.7 µW/cm of UV
intensity.
• Before opening doors and access panels bearing the ULTRAVIOLET RADIATION
hazard symbol for the conducting USER MAINTENANCE, it is recommended to
disconnect the power.
• UV-C BARRIERS bearing the ULTRAVIOLET RADIATION hazard symbol should not be
removed.
• Do not operate UV-C LAMPS outside of the appliance.
WIRING AND TRANSFORMER INSTALLATION NOTES
This device requires a constant 24V-AC power source. It is recommended that the device
be powered by a dedicated, non-cycling, 40VA transformer. Cycling this UV light will void the
lamp’s warranty and lessen the eective lifetime of the lamp. If powering from an existing
transformer already integrated on a furnace, air handler, or other appliance, an upgrade may
be required to the OE transformer. Ensure there is adequate volt-ampere (VA) capacity on
the existing transformer to support an additional 1.4A draw from this product
1. Verify the available volt amperes prior to connecting the UV xture to the 24VAC circuit. Energize
all 24VAC components so they reach their maximum amp load (Straight cool system - activate
cooling. Heat pump - activate heating mode.)
2. After obtaining the available volt amperes, determine if the existing transformer can accommodate
a 1.4 amp load.
3. Beware that inadequate transformers may initially seem to power up the circuit only to then
overheat as a result of an overdrawing system.
4. After installing the UV xture, energize all 24VAC components at their full amp draw, including the
UV xture, and ensure that all systems are operational and that fuses remain intact.
5. If the SUPPLY CORD is damaged, it must be replaced by the manufacturer, its service agent, or
similarly qualied persons in order to avoid a hazard.
