REPLACEMENT PARTS GUIDE
Replace cartridges every 6 months.
UV Lamps must be replaced annually in
order to maintain 99.9999% kill rate of
bacteria.
CARTRIDGE REPLACEMENT PROCEDURE
1. Turn off the power, then turn off the water supply by turning off the valve and
turning on a tap which is supplied by the lter to reduce system water pressure.
2. Open the cover and press the red pressure-relief button.
3. Using the cartridge wrench provided unscrew the lter housing, remove the large
O-ring, wipe clean, and set aside.
4. Discard the used lter cartridge. Wash the lter housing with dish soap & warm water
using a non-abrasive sponge or cloth. Rinse thoroughly. Fill 1/3 with water, add one
tablespoon of bleach and clean with non-abrasive cloth to disinfect. Rinse thoroughly.
5. Lubricate the O-ring with clean silicone grease. Do not use petroleum jelly. Insert
O-ring into the groove. This step is essential to ensure a proper lter housing seal.
Make sure the O-ring is seated level in the groove.
6. Insert the new lter cartridge. Screw the lter housing onto the cap and hand-
tighten. Do not over-tighten.
7. Turn on the water supply. Press the pressure-relief button. Check for leaks.
8. Turn on the power.
9. Lock the cover.
UV UNIT MAINTENANCE
SYSTEM MAINTENANCE
Check the ballast every few days to ensure the green ( or blue ) light is showing.
When the UV lamp has been working for 9000 hours ( 12 months ) it is time to replace
with a new lamp to make sure the UV system is working at its optimal performance.
To disassemble the UV lamp and quartz sleeve please see the instructions below.
CLEAN QUARTZ SLEEVE
The quartz sleeve needs to be cleaned regularly depending on water quality but as
a minimum once per year. If the sleeve appears cloudy or scaled up due poor water
quality clean the sleeve more regularly to avoid this happening. A cloudy or scaled up
sleeve will not be allowing the UV light to disinfect the water at its optimal level.
When cleaning the sleeve please use a soft non abrasive cloth and glass cleaner or for
stubborn stains vinegar or a slightly acid liquid such as a diluted citric acid cleaner.
Then clean and rinse the glass with clean water.
To disassemble the UV lamp and quartz sleeve please see the instructions below.
