4. MAINTENANCE & SERVICE
4B-3 Quartz Tube Installation
1. Place a sealing O-ring approximately 1/2in (12.7mm) from the end of the quartz tube. Insert quartz tube into the UV
reactor until it is fully seated.
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 5
.
2. Place the lamp retainer over the quartz tube and attach the lamp retainer using the lamp retainer screws and
washers as shown in
Figure 4
. Make sure the lamp retainer flanges are fully seated against the UV reactor.
3. Tighten main inlet and outlet fittings on the UV-C Pro.
4. Turn the circulation pump ON and check the quartz tube seals for leaks.
5. Turn the circulation pump OFF once you have confirmed that the quartz tubes are not leaking.
4B-4 Re-installing the UV Lamp(s)
NOTE:
Make sure to handle the UV lamp as described in
SECTION 4B-1
.
1. TURN OFF YOUR PUMP IF YOU HAVE NOT DONE SO.
2. Slowly press the UV lamp fully past the lamp retainer tabs and into the quartz tube until it is seated on the lamp
cushion in the bottom of the quartz tube.
3. Connect the UV lamp connector to the connector on the ballast.
ENVIRONMENTAL NOTICE:

Figure 6: Battery Replacement
4C. PLC Memory Backup Battery Replacement
1. On the top of the PLC, press the retaining clip on the battery door and swing the battery door open.
2. Remove the old battery from right side of the coin-type slot.
3. Install the new battery with the +, or flat, side out.
4. Close the battery door so that it locks securely.
5. Make note of the date the battery was replaced (it must be performed annually).
4D. Winterizing
If the pool will be shutting down for the winter months and the UV-C Pro will remain exposed to freezing temperatures, the
unit must be drained to prevent freeze damage to the wetted components. To drain the UV-C Pro, see the following steps.
1. If the UV-C Pro is mounted below the water level, 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 most water to drain from the UV-C Pro.
3. Open the door and locate the bottom quartz tube in each UV reactor (Refer to
Figure 4
). Remove these quartz
tubes to drain the remaining water from the UV reactor(s).
