UV Light Sleeve and Bulb installation
The Defender reverse osmosis systems UV light will not have the Quartz sleeve and bulb installed. This must be done on site.
1
UV Light Sleeve and Bulb installation
The use of cotton or latex gloves is recomended for this procedure as oils from the hands can leave residue on the sleeve and lamp which can ultimately block the UV light from getting to the water.
2
Carefully slide the sleeve into the reactor until you can feel it hit the opposite end of the reactor
Gently push it in to lock it into the internal centering tabs in the far side of the reactor.
CAUTION: Pushing too hard when the sleeve is not aligned can damage the tabs and can break the sleeve.
3
Slide the O-Ring onto the top of the sleeve until it is butted up against the reactor
4
Hand tighten the provided gland nut over the quartz sleeve onto the threaded end of the reactor
It has a positive stop to prevent over-tightening. A firm force may be required to fully tighten the gland nut.
DO NOT use tools to tighten the gland nut. Hand tight is sufficient.
5
Insert the provided stainless steel compression spring into the quartz sleeve
The spring works with the lamp and lamp connector to create the proper lamp alignment.
6
Remove the lamp from its packaging. Hold the lamp by the ceremic ends, not by the lamp quartz
Remove the lamp key from the lamp's connector and set it aside.
Be careful to not touch the key's exposed contacts. Insert the UV lamp into the reactor, being careful not to drop it.
BE SURE to install the UV lamp spring in the quartz sleeve prior to installing the bulb.
7
Install the lamp key into the controller mounted on the front of the Defender
Orient the lamp key so the label is upright and facing you during installation. The key will plug into the port on the right side of the controller.
8
Plug the lamp connector into the lamp
Note the notch for proper alignment. Insert the lamp connector into the gland nut and turn the connector approximately 1/4 turn to lock the connector to the gland nut.
9
Tighten the captive ground screw to the ground lug on the UV reactor to ensure proper grounding
IMPORTANT! Make sure the quartz sleeve is installed properly and make sure there are no leaks before installing the bulb and powering the UV light.
