Quartz Tube Removal and Cleaning (Every Six Months)
The UV lamps are housed in a quartz tube. If the quartz tube becomes dirty, its ability to transmit UV rays from the lamp will
be diminished. The quartz tube(s) should be removed from the UV reactor every six (6) months and cleaned if necessary.
Note: If the DEL AOP is installed below water level, the bypass valves must all be CLOSED to prevent excess pool water from
draining into the open unit when a quartz tube is removed.

1. Before continuing, allow adequate time for the quartz tubes to cool. Drain the water from the UV reactor by removing the
drain plug. Replace the plug once water has stopped exiting the UV reactor.
2.
After removing the lamps, remove the top lamp retainer screws using the hex key included in the parts bag. Place the lamp
retainer screws, washers and the lamp retainer aside in a safe place.
3. Grasp the quartz tube from the top of the UV reactor. Pull to remove it from the UV reactor.
4. Remove the sealing O-ring from the top of the quartz tube. Set aside in a safe place.
5. Clean the quartz tube exterior with a mild solution of muriatic acid (available at all pool supply stores) and water in a ratio
of four parts water to one part acid (4:1). If lime or hard water calcium deposits are encountered, use a household tub
and shower lime remover.
6.
After cleaning the quartz tube, wash it off and wipe dry. Inspect the quartz tube for cracks. Replace if cracks are found.
Make sure the inside of the quartz tube is dry before replacing the UV lamp(s).
CAUTION
Follow the directions for use and handling of muriatic acid on the acid bottle label, being careful to
protect your eyes, wear rubber gloves, and avoid breathing acid fumes.
Note: DO NOT USE ABRASIVE CLEANERS as they can scratch the high quality quartz glass. Note: DAMAGE CAUSED BY
BROKEN QUARTZ TUBES ARE NOT COVERED UNDER YOUR LIMITED WARRANTY.
