b. Installing the UV Lamp
i. make sure to handle the new lamp as described in section a and clean the uV Lamp before
installation if needed.
ii. slowly place the uV Lamp into the Quartz tube until it contacts the bottom of the tube.
iii. connect the Lamp connector plug to the pins on the lamp.
NOTE: do not force the Lamp connector plug onto the pins. if force is needed, it means that the
components are misaligned.
ENVIRONMENTAL NOTICE: uV Lamp contains mercury. manage in accordance with disposal
laws. see: www.lamprecycle.org
c. UV Reactor Service and Maintenance
the uV Lamp is housed in a Quartz tube. if the Quartz tube becomes dirty, its ability to transmit
rays from the uV Lamp will be diminished and decrease system performance. the Quartz tube
should be removed from the uV reactor at least once a year, or during a routine spa water
change for inspection and cleaning if necessary. DO NOT REMOVE THE QUARTZ TUBE WITH WATER
IN THE SPA
d. Quartz Tube Removal and Cleaning
CAUTION: Wear proper eye and skin protection for servicing glass components.
i. make sure the spa is shut down the water removed from the spa, and that the uV Lamp
and Quartz tube have cooled before performing maintenance on the Quartz tube.
ii. remove the upper enclosure assembly and uV Lamp as described in section a and set aside
in a safe place.
iii. remove the plastic compression nut. if there is any water remaining in the plumbing, it will
start to leak after the compression nut is removed.
iv. grasp the inside of the Quartz tube and pull it out of the housing. make sure the sealing
rings and compression washers do not get lost during Quartz tube removal.
v. inspect the sealing ring for nicks or hardness and the compression washers for cracks,
replace if necessary.
vi. clean the Quartz tube exterior with a mild solution of muriatic acid and water in a ratio
of four parts water to one part acid (4:1). do not use aBrasiVe cLeaners as they can
scratch the high quality quartz glass.
CAUTION: Follow the directions for safe use and handling of muriatic acid on the acid bottle label.
vii. after cleaning the Quartz tube, wash it off with water and wipe dry with a soft towel.
inspect the Quartz tube for cracks and replace if cracks are found.
