CAUTION: Always disconnect power to the UV-C Pro prior to performing service.
4B-1. UV Lamp Removal
1. Remove the UV service access panel from the top of the enclosure.
NOTE:
The UV-C Pro will not operate while the panel is removed.
2. After allowing adequate time for the UV lamps to cool, disconnect the UV lamp from the connector on the ballast.
3. Grasp the UV lamp wires and gently pull until the top of the UV lamp has pulled past the lamp retainer tabs.
4. Pull slowly on the white ceramic end of the UV lamp until the bottom has pulled past the lamp retainer tabs. If the
UV lamp is difficult to remove, use a slight twisting motion or remove the lamp retainer.
AVOID TOUCHING THE
UV LAMP GLASS WITH YOUR BARE HANDS.
Oils on your hands can cause hot spots on the UV lamp and shorten
its life. Use a soft clean cotton cloth or clean cotton gloves to handle the UV lamp. Carefully place the UV lamp in a
clean, dry, and safe location. Clean the UV lamp if necessary with alcohol and repeat this process for the other UV
lamps.
4B-2 Quartz Tube Removal and Cleaning
NOTE:
For instructions on cleaning without mechanical disassembly, see
Appendix
.
1. If the UV-C 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 UV-C Pro, this should allow sufficient water to drain from the UV
reactor(s).
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 top of 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).
