WHAT IT DOES
What Does the Puretec RL6 UV Lamp Do?
The RL6 produces ultraviolet light inside the UV chamber of a compatible Puretec treatment system.
As correctly pre-filtered water passes through the chamber, the ultraviolet treatment targets microorganisms by disrupting their ability to reproduce.
Puretec describes the RL6 as being used to target bacteria, viruses and other microorganisms, with applicable Puretec UV systems designed to achieve high levels of microbiological reduction under their specified operating conditions.
Ultraviolet Treatment
The lamp supplies the UV energy required by the compatible treatment chamber.
```
No Treatment Chemicals Added
UV treatment works using ultraviolet light rather than dosing the water with chlorine or another disinfectant chemical.
Part of a Complete System
The lamp works together with the UV chamber, quartz sleeve, electrical controller and appropriate upstream filtration.
```
ANNUAL UV LAMP REPLACEMENT
Replace the RL6 Every 12 Months
Puretec specifies that applicable UV lamps should be replaced annually to maintain the intended disinfection performance of the system.
A UV lamp can continue to illuminate after its recommended service interval, but visible light alone does not confirm that the lamp is still producing the required treatment output.
For that reason, lamp replacement should follow the manufacturer's annual maintenance schedule rather than waiting for the lamp to stop illuminating completely.

IMPORTANT DISTINCTION
A UV Lamp Does Not Replace Water Filtration
The RL6 performs the ultraviolet treatment stage. It does not act as a sediment cartridge, carbon filter or heavy-metal treatment cartridge.
It Does Not Remove Sediment
Dirt, rust, sand and silt need to be addressed by appropriate upstream particulate filtration.
```
It Does Not Remove Chlorine
Chlorine, unwanted taste and odour are normally treated using an appropriate carbon filtration stage.
Water Clarity Matters
UV treatment depends on sufficient ultraviolet light reaching the microorganisms, so suitable pre-filtration and water clarity are important.
```
WATER CLARITY
Why Pre-Filtration Matters Before UV Treatment
Puretec notes that UV-system effectiveness depends on the clarity of the water being treated.
Sediment and suspended material can reduce UV transmission through the water, which is why Puretec Hybrid systems combine filtration stages with ultraviolet treatment.
The exact pre-filtration arrangement depends on the Puretec system model, water source and water quality.
Replacing the UV lamp will not correct poor water clarity.
If the upstream cartridges are blocked, overdue or unsuitable for the incoming water conditions, those filtration components may also require servicing.
WHY REPLACE IT
Why Does a UV Lamp Need Replacing If It Still Lights Up?
The useful treatment life of a UV lamp is based on its ultraviolet output, not simply whether visible light can still be seen.
Puretec therefore specifies annual replacement of compatible UV lamps to maintain the treatment performance expected from the complete UV system.
Waiting for complete lamp failure can leave the lamp operating beyond the manufacturer's scheduled service period.
SYSTEM MONITORING
Lamp Timers & Failure Alarms
Selected Puretec UV systems include electronic monitoring features such as a lamp countdown timer and audible or visible lamp-failure alarm.
These features help identify scheduled lamp replacement or an operating fault, but the exact controller functions vary between Puretec system models.
If your controller indicates a lamp fault or replacement warning, check the system manual and confirm the correct lamp model before servicing.
REPLACEMENT PROCESS
What Is Involved in Replacing a Puretec RL6?
The exact replacement process should follow the instructions for the Puretec UV system in which the lamp is installed.
- Confirm the existing system specifies the RL6 lamp
- Disconnect electrical power before servicing
- Allow the UV assembly to cool
- Access the UV lamp connection carefully
- Disconnect the existing lamp from the controller lead
- Remove the lamp carefully from the quartz sleeve
- Avoid striking or damaging the quartz sleeve
- Install the replacement RL6 correctly
- Reconnect the lamp to the applicable controller
- Reassemble all protective covers or components
- Reset the lamp timer where required by the system
- Confirm normal controller operation after replacement
ELECTRICAL SAFETY
Always Isolate Power Before UV Lamp Maintenance
The RL6 is an electrical UV component and should never be removed while the system remains energised.
The lamp and UV chamber can also become hot during operation, so the assembly should be allowed to cool before maintenance begins.
Do not operate the UV lamp outside the chamber for viewing.
Ultraviolet light can be hazardous to eyes and skin. Follow the Puretec servicing procedure and keep the lamp installed within the applicable UV assembly during normal operation.
QUARTZ SLEEVE CHECK
Check the RQS6 Quartz Sleeve During Lamp Maintenance
Many systems using the RL6 also use the Puretec RQS6 quartz sleeve.
The quartz sleeve should be checked for scale, dirt or other buildup because deposits can reduce UV transmission through the chamber.
Puretec's UV maintenance guidance recommends regular quartz-sleeve inspection and cleaning where required. A cracked or damaged sleeve should be replaced before the UV system is returned to operation.
COMPLETE SYSTEM MAINTENANCE
Check Whether Other Service Components Are Due
Annual UV lamp replacement is a good opportunity to review the maintenance status of the complete filtration system.

MAINTENANCE KITS
RL6 Is Included in Selected Puretec Maintenance Kits
Puretec includes the RL6 in selected complete maintenance kits for compatible Hybrid systems.
Depending on the filtration-system model, a maintenance kit can include the applicable sediment and carbon cartridges, RL6 UV lamp, RQS6 quartz sleeve, O-rings and lubricant.
If several service components are due at the same time, check whether the manufacturer-specific maintenance kit for your system is more appropriate than purchasing the lamp on its own.
