Changing the UV Lamp
CAUTION: Always turn off power to the spa at
the GFCI prior to any maintenance .
Note: Periodically you should the check the light on the transformer
for the UV light system. The transformer is mounted in the spa
equipment area close to the system control box. When it is operating
normally, the light will be green. When it requires maintenance, it
will be red. This usually happens when the UV lamp needs replacing.

year.
When replacement UV lamp has been installed, conduct a
final leak check:
