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. Using the hex key included in the parts bag, loosen the bottom lamp retainer screws two full rotations.
4. Grasp the quartz tube from the top of the UV reactor. Pull to remove it from the UV reactor.
5. Remove the sealing O-ring from the top of the quartz tube. Set aside in a safe place. NOTE: O-Rings in the bottom
endcap of the reactor do not need to be removed for quartz tube service.
6. 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.
7. 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.
4C-3 Quartz Tube Installation
1. Holding the quartz tube so it is oriented straight up and down. Insert the quartz tube into the UV reactor until it is fully
seated in the bottom of the UV reactor.
Note: If the end of the quartz tube is protruding from the UV reactor, the alignment is off. Remove and re-insert the
quartz tube to seat it properly as shown in Figure 16.
2. Place a sealing o-ring approximately 1/2in (12.5mm) from the end of the quartz tube protruding from the top of the UV
reactor.
