4C-2 Quartz Tube Removal and Cleaning
NOTE:
For instructions on cleaning without mechanical disassembly, see
Appendix
.
1. If the AOP Pro is mounted below the water level, system isolation valves must all be CLOSED to prevent excess water
from draining into the unit.
2. Loosen main inlet and outlet fittings on the AOP Pro, this should allow sufficient water to drain from the AOP Pro.
3. Before continuing, allow adequate time for the UV lamps and quartz tubes to cool.
4. Remove the UV lamps as described in Section 4B-1.
5. Remove the top lamp retainer screws using the hex key included in the parts kit and remove the lamp retainer.
6. Grasp the quartz tube from the top of the UV reactor and pull to remove it from the UV reactor.
7. Remove the sealing O-ring from the quartz tube and set aside.
8. Wipe all residue from the quartz tube. If calcium deposits are encountered, use a mild solution (4:1) of water and
muriatic acid (available at pool supply stores), or household calcium/lime remover.
Follow the directions for use and handling of muriatic acid on the acid bottle label. Use proper eye and
skin protection and avoid breathing acid fumes.
NOTE: DO NOT USE ABRASIVE CLEANERS
as they can scratch the high quality quartz glass. 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).
NOTE:
DAMAGES CAUSED BY BROKEN QUARTZ TUBES ARE NOT COVERED UNDER THE LIMITED WARRANTY.
