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 wate, then drain the UV chamber of all 

water Let the filter cartridge dry out and then reinstall in the housing. To drain the UV, undo the SS flex connector from the bottom until the UV 

drains completely. Re-attach the flex connector. Leave the UV lamp and dome inside. When turning unit back on, plug the ballast first and slowly 

allow water into the unit. Wait for about 10 minutes and flush water through for a few minutes before consuming water.

PROBLEM

PROBABLE CAUSE

SOLUTION

Leak at gland nut

Gland nut is loose or O-ring defective

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

Condensation outside the UV chamber

High humidity in the environment

This is normal if humid conditions exist. 

Install dehumidifier to protect ballast. Protect 

flooring below UV

Hot water coming out of taps/faucets

Water inside UV unit becomes hot after long 

periods of non-use. You may have oversized 

the unit for the home

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

UV lamp ends seem burnt after some 

time

This is normal

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

Sump is difficult to remove

—

Unit may still be under pressure

—

Head seal may be stuck to sump

—

Close supply valve and open a faucet to    

    release pressure

—

To break the seal, use a pipe on the wrench            

    handle as extra leverage to open the housing.      

    

Never use wrench to tighten the sumps

.  

    Always lubricate the O-rings with food grade  

    silicone and replace annually

Leak at pressure relief valve    

Debris under vent seal

Replace vent O-ring
