• To reset lamp life countdown timer for 7 days, press and hold the silver button for 2-5 seconds. This can be done a maximum of 4 times (28 days).
• To reset the lamp life countdown timer after replacing the lamp, press and hold the silver button for 10 seconds.

Maintenance Instructions

• Before any maintenance, disconnect the power to the product, turn off the water supply to the product and open a downstream fixture for a few minutes or until the water flow stops. After the water flow has stopped close the downstream fixture, and then press the red buttons on top of the filter housing caps to release the pressure in the system. Place a tray underneath, if required, to catch any water that splashes. You may now begin maintenance.
• After any maintenance, check there is no moisture around the power supply, UV Ballast controller, cords or UV lamp connection. If there is any water, ensure that the power is disconnected before removing the water and allowing to fully dry before connecting the product to power.

WARNING: Connecting the product to power when there is water on or near the electronics could cause electrocution and/or product damage

• To start the product after maintenance, slowly turn on the water supply to the product and check for leaks. Open a fixture downstream of the product for 3 minutes to flush water through the system and remove any air pockets. Close the fixture downstream and then check for leaks again. Connect the product to the power supply and wait for 2 minutes for the UV lamp to reach full intensity.

Filter Cartridge Replacement

• Replacement of the filter cartridges is recommended at least every 1 year, or as required due to the supply water quality.

INFO: Sterilisation is achieved by exposing water to strong UV light for a period of time. Excessive sediment in the water will block some of the UV light from reaching pathogens, meaning that they may exit the UV sterilizer untreated. Good filtration of sediment is a critical step to ensure complete UV sterilization.

A 5-micron sediment filter (or smaller) must be installed upstream of a UV sterilizer. For your convenience, this product comes with a 5-micron sediment filter pre-installed to ensure optimum water treatment. The same cartridge should be used for replacement.

Steps to replace the filter cartridge (recommended at least every 1 year or as required):

1. Read the general maintenance instructions before starting the filter cartridge replacement.
2. After isolating and release the system pressure. Loosen the filter housing from the cap using the spanner to assist (turn clockwise when looking from above).
3. Carefully unscrew the filter housing, taking care as the weight of the filter housing with water can be heavy.
4. Empty excess water from the housing and remove the filter cartridge. Please dispose of the filter cartridge responsibly.
5. If necessary, clean the housing with dish soap and warm water and then rinse thoroughly.
6. Remove all packaging from the replacement filter cartridge. Record the model number of the cartridges you use & install date in the maintenance log at the back of this manual.
7. Insert the filter cartridge into the filter housing. For CTO filters, ensure that the rubber seal on the top and bottom are firmly in place before inserting into the housing. Ensure the filter cartridge is correctly seated on the spigot at the base of the filter housing.
8. Check O-rings are clean, undamaged and assembled correctly to the filter housing. Replace if necessary and lubricate using only 100% silicone food grade lubricant.
9. Hold the filter housing vertically whilst screwing the filter housing back into the cap. Ensure the top spigot is aligned with the center of the filter housing. Hand tighten the housing until firm, being careful not to overtighten. Do not overtighten the housings.
10. Read the general maintenance instructions on how to restart flow after replacing the cartridges.

UV Lamp Replacement

Steps to replace the UV Lamp (recommended at least every 1 year or as required):
