How to replace the UV Lamp and clean Quartz Dome:

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. CAUTION: The lamp end can be very hot. 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 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. Gently pull off the connector with your other hand to

disconnect the lamp completely. Slowly remove lamp from the disinfection chamber completely.

5. Remove the quartz dome by loosening the gland nut and carefully extracting from the unit. Remove dome absolutely vertically from its

position until the other end comes out. 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 & discard used dome O-ring. Clean dome gently with a vinegar solution or a household scale-removal product. Do not use abrasive

pads. A soft cloth or paper towel is recommended.

7. Using a small pointed tool carefully take the gland-nut O-ring out of the

gland nut. Take care not to scratch the gland nut.

8. A dome O-ring (thicker) and gland nut O-ring (thinner) are included

with the replacement lamp. Slide gland nut O-ring into the internal groove

of the gland nut.

9. Follow instructions 7 to 15 in previous section "Installing the UV Unit".

Do not plug in ballast yet.

10. 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.

Winterizing Your System:

To winterize the system, unplug the unit first. Drain the pre-filter by removing

the sump and dump the water, then drain the UV chamber of all water.

(H) TROUBLESHOOTING

Leak at gland nut

Condensation outside the UV chamber

Hot water coming out of taps/faucets

UV lamp ends seem burnt after

some time

PROBLEM

Gland nut is loose or O-ring defective

High humidity in the environment

Water inside UV unit becomes hot after long

periods of non-use. You may have oversized

the unit for the home

This is normal

PROBABLE CAUSE

Hand-tighten gland nut & replace O-ring(s)

This is normal if humid conditions exist.

Install dehumidifier to protect ballast. Protect

flooring below UV

To prevent scalding, before using water after

periods of non-use such as overnight, flush

water for about 2 minutes. Install a temper-

ature controlled purge valve on the UV outlet

As long as the UV lamp lights, a little burn

mark at the ends is normal and there is no

need to replace the UV lamp
