How to replace the UV Lamp:
1.
Unplug UV unit from electrical outlet and turn off supply valve before the unit. Open a faucet to depressurize the UV system
and turn off the valve at the UV outlet to isolate UV unit. Wait several minutes for the lamp to cool down.
2.
Unscrew the ground nut and remove the ground wire (green wire with yellow stripes).
3.
Loosen the black screw on the lamp connector cover and remove cover from the gland nut.
4.
Carefully slide UV lamp slightly out of chamber and hold the lamp end with one hand.
CAUTION:
The lamp end can be
very hot. Gently pull off the connector with your other hand to disconnect the lamp completely. Holding the lamp vertically,
slowly remove lamp from the disinfection chamber.
5.
Place an empty bucket below the bottom gland nut. Unscrew the top gland nut & remove. Slightly unscrew the bottom gland
nut until water comes out of the bottom end into the bucket. Holding the quartz dome vertically, slowly remove dome from
the disinfection chamber.
CAUTION:
If you bend the dome mid-way, it can break easily and pieces of quartz can fall into the UV chamber. Do not
lose the spring.
6.
Remove and discard used dome "O" rings. Clean the dome gently with a vinegar solution or household scale-removal
products.
7.
Using a small pointed tool carefully take the gland-nut "O" rings out of the gland nut. Take care not to scratch the gland nut.
8.
A pair of dome "O" rings (thicker) and gland nut "O" rings (thinner) are included with the replacement lamp. Slide gland nut
"O" ring into the internal groove of the gland nut.
9.
Replace one dome "O" ring on to quartz dome about 1" from the open end. Gently push the dome into the glandnut until it
touches the top. Carefully slide the quartz dome into the opening at the top of the UV chamber. With your other hand, use
your finger to guide the dome out through the bottom opening and hold the bottom end of the quartz dome to prevent it from
falling down. Slide the other dome “O” ring on the quartz dome at the bottom and screw on bottom gland nut (4031).
Hand tighten both gland nuts.
10. Slide the lamp spring (4036) into the quartz dome. Carefully unpack the new lamp and slide into the disinfection chamber.
Holding the lamp end, connect the lamp connector to the lamp. Slide the lamp connector cover over the top gland nut and
tighten the black screw. Re-connect ground wire.
11. Slowly open supply-valve and valves before and after the UV and check for leaks.
12. Depress timer button while reconnecting ballast to electrical outlet and keep the button depressed until the ballast emits
a solid three-second beep. This will re-set the lamp-change-timer to zero and the 3-second beep will confirm that the re-set
was successful.
13. Flush water through the UV for 2-3 minutes. The unit is ready for service.
Cleaning the Quartz Dome
: Some water conditions may require cleaning of the quartz dome more than once a year. To clean
quartz dome, follow the lamp-replacement instructions.
NOTE:
Do not depress timer-button when reconnecting ballast to
electrical outlet. The green lamp-ON LED will light, followed by three buzzer beeps and three red timer-LED flashes.
Important :
It is recommended that the quartz dome be replaced every three (3) years regardless of apparent condition.
