by tucking into wire channels. Ensure wires are
secured away from sharp edges and moving parts
to prevent damage.
Cover wires and plastic components within a
distance of 6" of the UV light with foil tape to
create a protective barrier from the UV light.

cabinet or on a service panel with “5253-039-
XXXX” printed in the lower right corner.)

light installed in Step 8 is ON in control panel.
Do NOT attempt to look at UV source to confirm
operation!
