Yearly bulb replacement
You will need: towels, bucket
1. Disconnect power to the waterfall
2. Turn both UV valves to the OFF position (perpendicular to
plumbing). This will prevent water from draining from the
waterfall while servicing. Water will be inside the UV fixture, so
have towels on hand.
3. Loosen the union valves at the ends of the UV to disconnect UV
fixture from waterfall.
4. Carefully remove from base and discard the leftover water into a
bucket or drain.
5. See instructions on page 7 to replace the UV bulb.
