Power Supply Installation
IMPORTANT
The UVL-FCU components are designed to with-
stand the typical ambient temperatures found
near fan coil and PTAC heating elements up to a
constant 194°F (90°C). If installing the lamp near
a heating element, secure the wires as far away
from the heating elements’ wires as possible to
prevent them from touching the element. In addi-
tion, use the included slit loom tubing for addi-
tional protection of the power supply wires that
may be mounted near the heating elements.
Find a suitable location for the power supply inside the
control panel of the air handler. Install using the self-
tapping screws.
